    Technological developments in photography have continued to facilitate and enhance the practice of dentistry. This evolution to a contemporary photographic process is revolutionizing the way clinicians diagnose, treat, and communicate with patients and colleagues. In this technologically progressing profession, clinicians should consider using an objective strategy for the selection and application of a reliable camera system that best suits the needs of their practice. This article provides clinicians with an overview of the function and basic components of a professional digital single lens reflex camera system, the criteria for evaluating and selecting a digital camera system, and the clinical applications for dental photography, as well as presents guidelines for obtaining a quality dental image.

    Dental photography is one of the special field in photography because of the particularity of the technology and approach. Lack of depth of field is one of the most possible problems for new learners. In dental photography, the control of depth of field depends on aperture only, deep depth of field can be achieved by decreasing the aperture. The parameters of exposure include aperture, shutter speed, flash intensity and ISO, which control the exposure together. The area of pictures is controlled by proportion, with manual exposure for getting right exposure. Manual focusing is suggested instead of auto focusing. The appropriate technology, method and right area are the most important factors for dental photography, and later treatment has to be avoided.

    Although the primary purpose of using digital photography in dentistry is for recording various aspects of clinical information in the oral cavity, other benefits also accrue. Detailed here are the uses of digital images for dento-legal documentation, education, communication with patients, dental team members and colleagues and for portfolios, and marketing. These uses enhance the status of a dental practice and improve delivery of care to patients. PMID:19424242

  6. Considerations for use of dental photography and electronic media in dental education and clinical practice.

    2015-04-01

    Photography and electronic media are indispensable tools for dental education and clinical practice. Although previous research has focused on privacy issues and general strategies to protect patient privacy when sharing clinical photographs for educational purposes, there are no published recommendations for developing a functional, privacy-compliant institutional framework for the capture, storage, transfer, and use of clinical photographs and other electronic media. The aims of this study were to research patient rights relating to electronic media and propose a framework for the use of patient media in education and clinical care. After a review of the relevant literature and consultation with the University of Washington's director of privacy and compliance and assistant attorney general, the researchers developed a privacy-compliant framework to ensure appropriate capture, storage, transfer, and use of clinical photography and electronic media. A four-part framework was created to guide the use of patient media that reflects considerations of patient autonomy and privacy, informed consent, capture and storage of media, and its transfer, use, and display. The best practices proposed for capture, storage, transfer, and use of clinical photographs and electronic media adhere to the health care code of ethics (based on patient autonomy, nonmaleficence, beneficence, justice, and veracity), which is most effectively upheld by a practical framework designed to protect patients and limit institutional liability. Educators have the opportunity and duty to convey these principles to students who will become the next generation of dentists, researchers, and educators.

    Digital cameras, when used correctly, can provide the basis for telemedicine services. The increasing sophistication of digital cameras, combined with the improved speed and availability of the Internet, make them an instrument that every health-care professional should be familiar with. Taking satisfactory images of patients requires clinical photography skills. Photographing charts, monitors, X-ray films and specimens also requires expertise. Image capture using digital cameras is often done with insufficient attention, which can lead to inaccurate study results. The procedures in clinical photography should not vary from camera to camera, or from country to country. Taking a photograph should be a standardised process. There are seven main scenarios in clinical photography and health professionals who use cameras should be familiar with all of them. Obtaining informed consent prior to photography should be a normal part of the clinical photography routine.

    The main objective was to assist in the production of electronic images in the Electronic Photography Lab (EPL). The EPL is a new facility serving the electronic photographic needs of the Langley community. The purpose of the Electronic Photography lab is to provide Langley with access to digital imaging technology. Although the EPL has been in operation for less than one year, almost 1,000 images have been produced. The decision to establish the lab was made after careful determination of the centers needs for electronic photography. The LaRC community requires electronic photography for the production of electronic printing, Web sites, desktop publications, and its increased enhancement capabilities. In addition to general use, other considerations went into the planning of the EPL. For example, electronic photography is much less of a burden on the environment compared to conventional photography. Also, the possibilities of an on-line database and retrieval system could make locating past work more efficient. Finally, information in an electronic image is quantified, making measurements and calculations easier for the researcher.

    We are just a few years away from celebrating the 200th anniversary of photography. The first permanent photographic record was made by Niepce in 1826, the view from his window at Le Gras. After many development cycles, including some periods of stagnation, photography is now experience an amazing period of growth. Change since the mid 90's going into the next several years will completely modify photography and its industry. We propose that the digital photography revolution can be divided into two phases. The first, from about 1994 to 2009, was primarily the transformation of film-based equipment into their digital counterparts. Now, in the second phase, photography is starting to change into something completely different, with forces like social networks, cell phone cameras and computational photography changing the business, the methods and the use of photographs.

    2010-09-10

    Photography often represents the best method to collect and preserve evidence in forensic cases. This is especially true in forensic odontology with cases involving dental identification, human abuse and, perhaps most significantly, bitemark cases. Basic visible light photography is adequate in most dental identification cases; however, full spectrum digital photography is best utilized to collect all available evidence in cases of human abuse and bitemarks. This paper will discuss the types of photographic evidence that should be collected with various forensic odontological cases and the specific techniques utilized in full spectrum forensic digital photography. The use of full spectrum photography captures the forensic injuries using special techniques recording the injuries in each of the four resultant events that occur when light strikes skin.

    The last few years have seen a number of new flaps described and a renewed interest in the use of fluorescein, but there have been few photographs of the fluorescein effect, because special light sources were required with the filters that were employed. The realization that fluorescein can be excited by electromagnetic radiation in the visible range allows a simplified technique in which an ordinary electronic flash unit may serve as the only light source. The photography of fluorescein is not difficult to perform, and since minimal additional equipment is required, all workers who use fluorescein should begin to document their work more accurately and dramatically.

    Antic scientists, sailors, warriors, physician, etc. were perceiving the space by means of their eye vision system. Nowadays the same people use eyeglasses, telescopes, microscopes, image converters. All these devices fit the necessary magnification, intensification gain and image spectrum to the eyes. The human brain is processing the image data offered to him in a format pertaining to eyes. Hence, the cognition of images can be regarded as a direct measurement. As to the time scale converters, they turned out to be harder done as compared with the spatial scale converters. Hence, the development of the high-speed photography (HSP) continues for more than a hundred and fifty years. The recent pico- femtosecond HSP branch sprang up in 1949 at the Kurchatov Institute -- its cradle. All about the HSP had been advertised. Instead of reprinting what is already well known, it makes sense to emphasize some instructive lessons drawn from past experience. Also it is tempting to look a bit into the high-speed photography future.

    2001-12-20

    A new technique that enables frequency-resolved cavity ringdown absorption spectra to be obtained over a large optical bandwidth by a single laser shot is described. The technique, ringdown spectral photography (RSP), simultaneously employs two key principles to record the time and frequency response of an optical cavity along orthogonal axes of a CCD array detector. Previously, the principles employed in RSP were demonstrated with narrow-band laser light that was scanned in frequency [Chem. Phys. Lett. 292, 143 (1998)]. Here, the RSP method is demonstrated using single pulses of broadband visible laser light. The ability to obtain broad as well as rotationally resolved spectra over a large bandwidth with high sensitivity is demonstrated. PMID:18364983

    The Aerial Photography Summary Record System (APSRS) describes aerial photography projects that meet specified criteria over a given geographic area of the United States and its territories. Aerial photographs are an important tool in cartography and a number of other professions. Land use planners, real estate developers, lawyers, environmental specialists, and many other professionals rely on detailed and timely aerial photographs. Until 1975, there was no systematic approach to locate an aerial photograph, or series of photographs, quickly and easily. In that year, the U.S. Geological Survey (USGS) inaugurated the APSRS, which has become a standard reference for users of aerial photographs.

  4. Medical photography: principles for orthopedics

    PubMed Central

    2014-01-01

    Background Medical photography is used clinically for patient evaluation, treatment decisions, and scientific documentation. Although standards for medical photography exist in many branches of medicine, we have not encountered such criteria in publications in the area of orthopedics. Purpose This study aims to (1) assess the quality of medical images used in an orthopedic publication and (2) to propose standards for medical photography in this area. Methods Clinical photographs were reviewed from all issues of a journal published between the years 2008 and 2012. A quality of clinical images was developed based on the criteria published for the specialties of dermatology and cosmetic surgery. All images were reviewed on the appropriateness of background, patient preparation, and technique. Results In this study, only 44.9% of clinical images in an orthopedic publication adhered to the proposed conventions. Conclusions Standards have not been established for medical photography in orthopedics as in other specialty areas. Our results suggest that photographic clinical information in orthopedic publications may be limited by inadequate presentation. We propose that formal conventions for clinical images should be established. PMID:24708703

  6. Photography-based image generator

    NASA Astrophysics Data System (ADS)

    Dalton, Nicholas M.; Deering, Charles S.

    1989-09-01

    A two-channel Photography Based Image Generator system was developed to drive the Helmet Mounted Laser Projector at the Naval Training System Center at Orlando, Florida. This projector is a two-channel system that displays a wide field-of-view color image with a high-resolution inset to efficiently match the pilot's visual capability. The image generator is a derivative of the LTV-developed visual system installed in the A-7E Weapon System Trainer at NAS Cecil Field. The Photography Based Image Generator is based on patented LTV technology for high resolution, multi-channel, real world visual simulation. Special provisions were developed for driving the NTSC-developed and patented Helmet Mounted Laser Projector. These include a special 1023-line raster format, an electronic image blending technique, spherical lens mapping for dome projection, a special computer interface for head/eye tracking and flight parameters, special software, and a number of data bases. Good gaze angle tracking is critical to the use of the NTSC projector in a flight simulation environment. The Photography Based Image Generator provides superior dynamic response by performing a relatively simple perspective transformation on stored, high-detail photography instead of generating this detail by "brute force" computer image generation methods. With this approach, high detail can be displayed and updated at the television field rate (60 Hz).

    2004-12-01

    Government, media and public focus on waiting times in the National Health Service in the United Kingdom has forced the organization to look closely at the process by which a patient progresses through an increasingly complex and ever changing system. In an effort to streamline the patient journey or care pathway, modernizers have turned to business and manufacturing for solutions. Whilst medical photographers need to recognize their role in this context, they are also facing major technological modernization through the development of digital photography. Part 1 of this paper looks at the origins of some of the techniques presently being used to modernize the patient journey. Part 2 shows how these tools of modernization can be utilized to harness the advantages of digital technology to provide a modern and appropriate medical photography service in a large, disparate teaching hospital.

    Part 1 of this paper explored the origins of process activity mapping, one of the major tools currently being used to modernize patient pathways in the National Health Service in Great Britain. Within medical photography the current notion of modernization is inextricably linked to the development of digital technology. Whilst the core principle of capturing light on a sensitive medium remains as clear and relevant as ever, the mechanisms by which the image is processed and presented to the client have changed profoundly. Part 2 shows how the principles of lean thinking and process activity mapping can be utilized to harness the advantages of digital technology to provide a modern and appropriate medical photography service in a large disparate teaching hospital.

    The application of speckle photography in biomechanical testing of bones and surgical fixing devices is presented. Double-exposure speckle photography is used for measuring the in-plane deformation of broken lower leg bones supported with different fixing devices under axial loading. An osteosynthesis plate, an external fixator, and an intramedullar nail mounted on the tibia shaft are tested. The results for different loading conditions are analyzed and compared with those obtained by holographic interferometry. Further, the human hyoid bone is investigated by this method. The load is applied to the anterior surface of the body of the bone. All tested specimen show an asymmetric displacement, the greatest in a plane vertical to the load. An evaluation of fracture behavior can be done from the displacement pattern.

  13. Ethical considerations in dermatologic photography.

    PubMed

    Lakdawala, Nikita; Fontanella, Demian; Grant-Kels, Jane M

    2012-01-01

    In dermatology, clinical photographs are an essential component of patient care, enabling clinicians to document changes in skin pathology over time. Recent advances in digital technology and the electronic medical record have revolutionized clinical photography; however, these advances bring with them new ethical, legal, and social concerns. Photographs, more than other forms of documentation, have the potential to make patients uncomfortable. The act of photography, especially for those images requiring exposure of the genital area or the entire body, can be an uncomfortable experience for patients, necessitating the clinician and photographer to take an empathic stance in this setting. The Internet has elicited an increasing, and a very real, concern for patients about possible distribution and use of images outside of their individual care. The clinician and staff can allay these fears by professionally and empathetically addressing their concerns. In addition, it is important that patients receive appropriate informed consent about clinical photographs and the potential use of the images in their care, education, and research. Given the multitude of methods for recording clinical photographs, combined with the increasing complexity of image storage, standardization becomes a critical tool in providing consistency among images and achieving more equitable and efficacious care. To achieve this goal and improve the baseline standard of continuity of care for dermatological practices, we review the role of photographs, develop a model for patient consent, and establish standards for photography so as to provide the most ethical care for the patient.

  14. Flash photography-induced maculopathy

    PubMed Central

    Veugelen, Tim; Coutteel, Carine; Leys, Anita

    2011-01-01

    Objective: To report a flash photography-induced maculopathy. Methods: A professional photographer blinded himself accidentally and he consulted 3 days after the event with a scotoma in his dominant left eye. A unilateral acute light-induced maculopathy with hemorrhage was observed. The lesion was studied with colour photography, fluorescein and indocyanin angiography, autofluorescence imaging and repeated optical coherence tomography (OCT) imaging. Results: At age 43, this professional photographer was blinded by the flash light of his camera and subsequently realized he had a scotoma in his dominant eye. Three days after the event visual acuity (VA) was 20/70 and an acute light-induced maculopathy was noted. Another three days later, VA was 20/50 and the lesions were less prominent. After one month, the photographer still had problems making sharp pictures, VA was 20/25 and a macular scar was observed. During further follow-up, he regained full vision and experienced no professional problems. Conclusions: This case illustrates that the light of flash photography can accidentally hit an eye and induce a light-induced maculopathy.

  16. Ocular Fundus Photography as an Educational Tool.

    PubMed

    Mackay, Devin D; Garza, Philip S

    2015-10-01

    The proficiency of nonophthalmologists with direct ophthalmoscopy is poor, which has prompted a search for alternative technologies to examine the ocular fundus. Although ocular fundus photography has existed for decades, its use has been traditionally restricted to ophthalmology clinical care settings and textbooks. Recent research has shown a role for nonmydriatic fundus photography in nonophthalmic settings, encouraging more widespread adoption of fundus photography technology. Recent studies have also affirmed the role of fundus photography as an adjunct or alternative to direct ophthalmoscopy in undergraduate medical education. In this review, the authors examine the use of ocular fundus photography as an educational tool and suggest future applications for this important technology. Novel applications of fundus photography as an educational tool have the potential to resurrect the dying art of funduscopy.

    2015-05-01

    In this paper the accommodation responses for integral photography still images were measured. The experimental results showed that the accommodation responses for integral photography images showed a linear change with images showing the depth position of integral photography, even if the integral photography images were located out of the depth of the field. Furthermore, the discrimination of depth perception, which relates to a blur effect in integral photography images, was subjectively evaluated for the examination of its influence on the accommodation response. As a result, the range of the discrimination of depth perception was narrow in comparison to the range of the rectilinear accommodation response. However, these results were consistent according to the propensity of statistical significance for the discrimination of depth perception in the out range of subjectively effective discriminations.

    Plastic surgery and photography are inseparable and with present-day technology, it is much easier and more affordable than ever before to incorporate high-quality and standardized images into clinical practice. Perfecting digital photography can have a learning curve that is many times hindered by old habits from the days of slide photography, macro lenses, and specialized flashes, which made it more difficult and complex to incorporate into a busy plastic surgery practice. With the current digital revolution, many of these barriers have been or can be eliminated and anyone can become a proficient photographer. The purpose of this article, first in a series, is to introduce the plastic surgical nurse to the history of photography and applications and the benefits of digital photography.

  3. Measuring gloss by digital photography

    NASA Astrophysics Data System (ADS)

    Kumar, Pancham; MacDonald, Lindsay

    2006-01-01

    The measurement of gloss is conventionally made by specialised instruments that determine the ratio of reflected to incident illumination at a single fixed angle. This study investigated whether digital photography with flash illumination could be used as an alternative. Multiple exposures were combined by a high dynamic range (HDR) imaging technique to produce a two-dimensional intensity profile of the reflectance around the specular point. The method was tested for six paper samples of varying gloss, and the results were found to correlate well with instrumental measurements. The image gloss profiles, however, provided more information about the distribution of the reflection over a range of angles and also gave an indication of the surface texture.

  5. Evaluation of multiband photography for rock discrimination

    NASA Technical Reports Server (NTRS)

    Raines, G. L.

    1974-01-01

    An evaluation is presented of the multiband photography concept that tonal differences between rock formations on aerial photography can be improved through the selection of the appropriate bands. The concept involves: (1) acquiring band reference data for the rocks being considered; (2) selecting the best combination of bands to discriminate the rocks using these reference data; (3) acquiring aerial photography using these selected bands; and (4) extracting the desired geologic information in an optimum manner. The test site geology and rock reflectance are discussed in detail. The evaluation found that the differences in contrast ratios are not statistically significant, and the spectral information in different bands is not advantageous.

    It is reported that the Apollo 16 command module astronomical photography was performed with the specific objective of capitalizing on the uniqueness of the double umbra as a vantage point to collect astronomical data that are obtainable only near our Moon. For this reason, these data will be compared directly to analogous photography performed from Earth orbit during Project Mercury and the Gemini Program as well as to the Apollo-duplicated photography taken from sites on the Earth surface. Comparison with Earth-based photography should yield direct information on the Earth airglow layer and on atmospheric scattering and extinction.

  11. Dental Implants.

    PubMed

    Zohrabian, Vahe M; Sonick, Michael; Hwang, Debby; Abrahams, James J

    2015-10-01

    Dental implants restore function to near normal in partially or completely edentulous patients. A root-form implant is the most frequently used type of dental implant today. The basis for dental implants is osseointegration, in which osteoblasts grow and directly integrate with the surface of titanium posts surgically embedded into the jaw. Radiologic assessment is critical in the preoperative evaluation of the dental implant patient, as the exact height, width, and contour of the alveolar ridge must be determined. Moreover, the precise locations of the maxillary sinuses and mandibular canals, as well as their relationships to the site of implant surgery must be ascertained. As such, radiologists must be familiar with implant design and surgical placement, as well as augmentation procedures utilized in those patients with insufficient bone in the maxilla and mandible to support dental implants.

  12. Flexible depth of field photography.

    PubMed

    Kuthirummal, Sujit; Nagahara, Hajime; Zhou, Changyin; Nayar, Shree K

    2011-01-01

    The range of scene depths that appear focused in an image is known as the depth of field (DOF). Conventional cameras are limited by a fundamental trade-off between depth of field and signal-to-noise ratio (SNR). For a dark scene, the aperture of the lens must be opened up to maintain SNR, which causes the DOF to reduce. Also, today's cameras have DOFs that correspond to a single slab that is perpendicular to the optical axis. In this paper, we present an imaging system that enables one to control the DOF in new and powerful ways. Our approach is to vary the position and/or orientation of the image detector during the integration time of a single photograph. Even when the detector motion is very small (tens of microns), a large range of scene depths (several meters) is captured, both in and out of focus. Our prototype camera uses a micro-actuator to translate the detector along the optical axis during image integration. Using this device, we demonstrate four applications of flexible DOF. First, we describe extended DOF where a large depth range is captured with a very wide aperture (low noise) but with nearly depth-independent defocus blur. Deconvolving a captured image with a single blur kernel gives an image with extended DOF and high SNR. Next, we show the capture of images with discontinuous DOFs. For instance, near and far objects can be imaged with sharpness, while objects in between are severely blurred. Third, we show that our camera can capture images with tilted DOFs (Scheimpflug imaging) without tilting the image detector. Finally, we demonstrate how our camera can be used to realize nonplanar DOFs. We believe flexible DOF imaging can open a new creative dimension in photography and lead to new capabilities in scientific imaging, vision, and graphics. PMID:21088319

    2011-01-01

    Objective: The aim of this paper is to document the practice of photography among clinicians whose daily work depends and is influenced so much by medical photography. Materials and Methods: Questionnaires documenting the bio data, place of practice, and experience of cleft caregivers with clinical photography were distributed. Knowledge of rules guiding clinical photography and adherence to them were also asked. Types of camera used were documented and knowledge of the value of clinical photographs were also inquired. Results: Plastic surgeons constitute the highest proportion of 27 (38.6%), followed by Oral and Maxillofacial surgeons with 14 (20.0%). Twenty one (30.0%) of the respondents always, 21 (30.0%) often, 12 (17.1%) frequently, while 9 respondents sometimes took photographs of their patients. Suggested uses of clinical photographs included training, 52 (74.3%), education, 51 (72.9%), medicolegal, 44 (62.9%) and advertisement, 44 (62.9%) among others. Twenty two (31.4%) did not know that there were standard guidelines for taking clinical photographs. Twenty three (32.9%) of them did not seek the consent of the patients before taking clinical photographs. Conclusion: While the practice of clinical photography is high among African cleft caregivers, there is a need for further education on the issues of standard rules and obtaining consent from patients.

  14. Dental OCT

    NASA Astrophysics Data System (ADS)

    Wilder-Smith, Petra; Otis, Linda; Zhang, Jun; Chen, Zhongping

    This chapter describes the applications of OCT for imaging in vivo dental and oral tissue. The oral cavity is a diverse environment that includes oral mucosa, gingival tissues, teeth and their supporting structures. Because OCT can image both hard and soft tissues of the oral cavity at high resolution, it offers the unique capacity to identity dental disease before destructive changes have progressed. OCT images depict clinically important anatomical features such as the location of soft tissue attachments, morphological changes in gingival tissue, tooth decay, enamel thickness and decay, as well as the structural integrity of dental restorations. OCT imaging allows for earlier intervention than is possible with current diagnostic modalities.

    A system is described that electronically controls the medical photography for a computed tomography (CT) scanner system. Multiple CT exams can be photographed with each image automatically adjusted to a specific gamma table presentation and positioned to any film location within a given film format. Our approach uses a library that can store 24 CT exam photography protocols. Library entries can be added, deleted, or edited. Mixed film formats, multiple image types, and automated annotation capabilities allow all CT exams to be filmed at our clinic cost-effectively and unattended. Using this automated approach to CT exam photography, one full-time equivalent CT technologist has been saved from the operational cost of our center. We outline the film protocol database, illustrate protocol options and by example, show the flexibility of this approach. Features of this system illustrate essential components of any such approach.

    The primary objectives of the earth observations and photography experiment of the Apollo Soyuz Test Project were to photograph various terrestrial structures and to use the capabilities of man as a trained observer in visually studying earth features and phenomena. Man's special capabilities include the sensitivity of the eye to subtle color variations and the speed with which the eye/brain system can interpret what is seen and select targets for photography. Real time astronaut observations constitute a useful complement to orbital photographs and greatly aid in their interpretation. Targets for mapping and hand held photography were selected on the basis of their value to specialists in the earth sciences including geology, oceanography, desert study, hydrology, meteorology, and environmental science.

    1980-01-01

    Results of a one-year experimental study on the use of aerial color infrared photography in citrus grove management are presented. It is found that the spring season, when trees are in flush (have young leaves), is the best season to photograph visible differences between healthy and diseased trees. It is also shown that the best photography can be obtained with a 12-in. focal length lens. The photographic scale that allowed good photo interpretation with simple inexpensive equipment was 1 in. = 330 ft. The use of a window-overlay transparency method allowed rapid photo interpretation and data recording in computer-compatible forms. Aerial color infrared photography carried out during the spring season revealed a more accurate status of tree condition than visual inspection.

  18. Ethereal presences in holography and photography

    NASA Astrophysics Data System (ADS)

    Richardson, M.; Byrne, Kay

    2007-02-01

    This paper examines the concept of the 'Presence of Absence' in post-mortem photography and holography, drawing upon both historical and lesser-known images as reference. To create a photographic negative one needs the presence of light to expose the light sensitive surface, be it glass, a polished plate or plastic. A hologram may also be created when a coherent light source, for example from a Laser, travels through a light sensitive material and falls upon the subject to be recorded. A holograph however, retains the optical qualities of both phase and amplitude, the memory of light. Both mediums recall, as it were, 'now absent moments', and confronts us with what is 'not there' as much as 'what is'. This paper examines the exploration of absence and presence in post-mortem photography and holography and it's a richly visceral visual language. A photonic syntax can interpret death as an elegant yet horrific aesthetic, the photograph may be beautify screened and yet obscene in its content. In essence one can be a voyeur, experiencing a mere visual whisper of the true nature of the subject. Our Victorian forefathers explored postmortem photography as an object of mourning, and at the close of the nineteenth century when Jack the Ripper had the inhabitants of White Chapel in a grip of fear, photography made its mark as a documentation of violent crime. Today, within contemporary photography, death is now presented within the confines of the 'Art Gallery', as a sensual, and at times, sensationalised art form. In exploring post-mortem imagery, both in holography and conventional photography, absence presents an aspect of death as startling in its unanimated form and detailed in its finite examination of mortality.

    Colour imaging of fundus tumours has been transformed by the development of digital and confocal scanning laser photography. These advances provide numerous benefits, such as panoramic images, increased contrast, non-contact wide-angle imaging, non-mydriatic photography, and simultaneous angiography. False tumour colour representation can, however, cause serious diagnostic errors. Large choroidal tumours can be totally invisible on angiography. Pseudogrowth can occur because of artefacts caused by different methods of fundus illumination, movement of reference blood vessels, and flattening of Bruch's membrane and sclera when tumour regression occurs. Awareness of these pitfalls should prevent the clinician from misdiagnosing tumours and wrongfully concluding that a tumour has grown. PMID:23238442

    2016-01-01

    Background An inverse relationship between dental calculus mineralization and dental caries demineralization on teeth has been noted in some studies. Dental calculus may even form superficial layers over existing dental caries and arrest their progression, but this phenomenon has been only rarely documented and infrequently considered in the field of Cariology. To further assess the occurrence of dental calculus arrest of dental caries, this study evaluated a large number of extracted human teeth for the presence and location of dental caries, dental calculus, and dental plaque biofilms. Materials and methods A total of 1,200 teeth were preserved in 10% buffered formal saline, and viewed while moist by a single experienced examiner using a research stereomicroscope at 15-25× magnification. Representative teeth were sectioned and photographed, and their dental plaque biofilms subjected to gram-stain examination with light microscopy at 100× magnification. Results Dental calculus was observed on 1,140 (95%) of the extracted human teeth, and no dental carious lesions were found underlying dental calculus-covered surfaces on 1,139 of these teeth. However, dental calculus arrest of dental caries was found on one (0.54%) of 187 evaluated teeth that presented with unrestored proximal enamel caries. On the distal surface of a maxillary premolar tooth, dental calculus mineralization filled the outer surface cavitation of an incipient dental caries lesion. The dental calculus-covered carious lesion extended only slightly into enamel, and exhibited a brown pigmentation characteristic of inactive or arrested dental caries. In contrast, the tooth's mesial surface, without a superficial layer of dental calculus, had a large carious lesion going through enamel and deep into dentin. Conclusions These observations further document the potential protective effects of dental calculus mineralization against dental caries. PMID:27446993

    For BOReal Ecosystem-Atmosphere Study (BOREAS), C-130 and other aerial photography was collected to provide finely detailed and spatially extensive documentation of the condition of the primary study sites. The NASA C-130 Earth Resources aircraft can accommodate two mapping cameras during flight, each of which can be fitted with 6- or 12-inch focal-length lenses and black-and-white, natural-color, or color-IR film, depending upon requirements. Both cameras were often in operation simultaneously, although sometimes only the lower resolution camera was deployed. When both cameras were in operation, the higher resolution camera was often used in a more limited fashion. The acquired photography covers the period of April to September 1994. The aerial photography was delivered as rolls of large format (9 x 9 inch) color transparency prints, with imagery from multiple missions (hundreds of prints) often contained within a single roll. A total of 1533 frames were collected from the C-130 platform for BOREAS in 1994. Note that the level-0 C-130 transparencies are not contained on the BOREAS CD-ROM set. An inventory file is supplied on the CD-ROM to inform users of all the data that were collected. Some photographic prints were made from the transparencies. In addition, BORIS staff digitized a subset of the tranparencies and stored the images in JPEG format. The CD-ROM set contains a small subset of the collected aerial photography that were the digitally scanned and stored as JPEG files for most tower and auxiliary sites in the NSA and SSA. See Section 15 for information about how to acquire additional imagery.

  11. Mars Cameras Make Panoramic Photography a Snap

    2008-01-01

    If you wish to explore a Martian landscape without leaving your armchair, a few simple clicks around the NASA Web site will lead you to panoramic photographs taken from the Mars Exploration Rovers, Spirit and Opportunity. Many of the technologies that enable this spectacular Mars photography have also inspired advancements in photography here on Earth, including the panoramic camera (Pancam) and its housing assembly, designed by the Jet Propulsion Laboratory and Cornell University for the Mars missions. Mounted atop each rover, the Pancam mast assembly (PMA) can tilt a full 180 degrees and swivel 360 degrees, allowing for a complete, highly detailed view of the Martian landscape. The rover Pancams take small, 1 megapixel (1 million pixel) digital photographs, which are stitched together into large panoramas that sometimes measure 4 by 24 megapixels. The Pancam software performs some image correction and stitching after the photographs are transmitted back to Earth. Different lens filters and a spectrometer also assist scientists in their analyses of infrared radiation from the objects in the photographs. These photographs from Mars spurred developers to begin thinking in terms of larger and higher quality images: super-sized digital pictures, or gigapixels, which are images composed of 1 billion or more pixels. Gigapixel images are more than 200 times the size captured by today s standard 4 megapixel digital camera. Although originally created for the Mars missions, the detail provided by these large photographs allows for many purposes, not all of which are limited to extraterrestrial photography.

    External cutaneous photography involves photographic documentation, which helps in treatment planning, documentation of facial features, teaching, publishing and pre- and post-procedural comparisons. The key is not simply documenting, but documenting it the right way and ensuring that photography is standardised and reproducible. In this review, basic photography techniques, standardised and reproducible angles such as frontal, oblique and lateral views and specific photographic angles for conditions such as facial rejuvenation are discussed. Use of photography accessories and a few tips on how to click good photographs in the examination room and how to achieve consistency in standardised photography are also presented. External photography in ophthalmic and facial plastic surgery like any other speciality too has standardised guidelines. Even small variations cause a drastic change in the photos and it's clinical and research value. Unless stringent criteria are met, the photographs lose their relevance and impact. PMID:27398013

Students are concerned with such issues as a universally accepted, non-patient-based licensure process, mid-level providers, loan availability and tax deductibility, financial support for schools, and service early in one's professional career (giving forward rather than giving back). Through collaboration with the American Dental Education Association and with many state associations, students participate in lobbying, awareness campaigns, and behind the scenes as legislative aids. Although students share the same love for the profession that animates established practitioners, they are perceived by legislators as being different. Students are involved in the legislative process because it represents their future.

    In most crimes where bite marks are discovered, photographic accuracy is crucial to the investigative process since in many instances the bite mark(s) may be the only evidence linking a particular suspect to the crime. Therefore, the rationale for employing superior photographic principles is mandatory for the investigation team. This paper will discuss current standards, best practice, and armamentaria for digital photography of bite mark injuries on skin. Full spectrum protocols will be described including Alternate Light Imaging, Reflective Ultra-violet, and Infrared techniques for photo-documentation of images of bite marks and other bruise patterns that have been inflicted on human skin.

    A medical photograph can transfer more information to a health professional than subjective descriptions, which are open to misinterpretation. For the best photographic results, a medical photographer should be used. However, in small hospitals, or in the community, this is not always practicable, therefore nurses should have some knowledge of the most appropriate equipment to use, and know the techniques to employ to attain consistent results. Consistency is one of the most important aspects of medical photography as it allows for comparisons between photographic images over time.

    The digital photography of foods method accurately estimates the food intake of adults and children in cafeterias. When using this method, images of food selection and leftovers are quickly captured in the cafeteria. These images are later compared with images of 'standard' portions of food using computer software. The amount of food selected and discarded is estimated based upon this comparison, and the application automatically calculates energy and nutrient intake. In the present review, we describe this method, as well as a related method called the Remote Food Photography Method (RFPM), which relies on smartphones to estimate food intake in near real-time in free-living conditions. When using the RFPM, participants capture images of food selection and leftovers using a smartphone and these images are wirelessly transmitted in near real-time to a server for analysis. Because data are transferred and analysed in near real-time, the RFPM provides a platform for participants to quickly receive feedback about their food intake behaviour and to receive dietary recommendations for achieving weight loss and health promotion goals. The reliability and validity of measuring food intake with the RFPM in adults and children is also reviewed. In sum, the body of research reviewed demonstrates that digital imaging accurately estimates food intake in many environments and it has many advantages over other methods, including reduced participant burden, elimination of the need for participants to estimate portion size, and the incorporation of computer automation to improve the accuracy, efficiency and cost-effectiveness of the method.

    Dental caries continues to be the most prevalent bacteria-mediated non-contagious disease of humankind. Dental professionals assert the disease can be explained by poor oral hygiene and a diet rich in sugars but this does not account for caries free individuals exposed to the same risk factors. In order to test the hypothesis that amount of amelogenin during enamel development can influence caries susceptibility, we generated multiple strains of mice with varying levels of available amelogenin during dental development. Mechanical tests showed that dental enamel developed with less amelogenin is "weaker" while the dental enamel of animals over-expressing amelogenin appears to be more resistant to acid dissolution.

    This article describes Colombia's development of formal dentistry, its dental school system, curriculum, and dental licensure, and current issues in oral health care. In 1969, there were only 4 dental schools in Colombia; at this writing there are 21. Five dental schools are public and the other 16 are private. Nearly all classes are conducted in Spanish. Undergraduate pre-dental coursework is not a prerequisite for dental school in Colombia. To obtain licensure, Colombian dental students must complete 5 years of study in dental school, earn a diploma, and work for the government for 1 year. There are approximately 41,400 dentists in Colombia, and the number is increasing quickly. However, the unemployment rate among dentists is very high, even though graduation from dental school is extremely difficult. Although the 1,100:1 ratio of citizens to dentists is considered satisfactory, access to dental care is limited due to the high rate of poverty. PMID:20339245

    There is substantial evidence supporting the use of cutaneous imaging in combination with standard total-body skin examinations for early detection and treatment of melanoma. In the last 2 decades, total-body photography (TBP) has been widely used in combination with standard total-body skin examinations for active skin cancer surveillance with proven clinical utility; however, the groundbreaking image detail provided by gigapixel photography (GP) could improve dermatologists' ability to monitor suspicious lesions and therefore could serve a critical role in supplementing traditional total-body skin examinations for skin cancer surveillance. Although it has been successfully implemented in other fields, future studies are required to determine the effectiveness of GP in dermatology.

    This investigation focuses on the potential use of astronaut acquired photography for the validation of current, land cover maps. More specifically, this study is directed at assessing the potential for the use of astronaut acquired photography to document and validate land cover change. Space Shuttle, astronaut acquired photography is employed to test the potential utility of data that may be acquired by astronauts employing the Window Observational Rack Facility (WORF) on International Space Station (ISS). The majority of astronaut acquired photography has been obtained under conditions similar to ISS operations in terms of both spectral as well as spatial resolution. Validation of land cover maps utilizing this type of imagery is being accomplished through a process of comparison among three different land cover classification legends created from the Eros Data Center (EDC) Land Characteristics Database. Our study area is a subregional scale portion of an Advanced Very High Resolution Radiometer (AVHRR) based global Land Characteristics Database. The goal of this research is to attempt to establish: 1. which legend derived for this area provides the highest overall accuracy for the land cover classes present: 2. which legend is best validated using astronaut acquired photography; and 3. which classes of these legends best lend themselves to validation with astronaut acquired photography. Preliminary results indicate that astronaut acquired photography can be employed to validate land cover maps and that results achieved using this imagery corresponds well to those achieved utilizing Landsat data. .

    A 14-year-old girl developed dental pain and was treated for acute infected pulpitis of her right upper lateral incisor with drilling and filling. The pain continued and was helped by analgesia, sucking ice cubes and drinking cold water. Forty-eight hours later, she became confused and disoriented. She started to vomit and complained of headache. Investigations revealed hyponatraemia with normal serum potassium levels and initially normal urinary sodium excretion. Over the next 24 hours, she passed 5.45 L of urine and her serum sodium rose from 125 to 143 mmol/L. Self-induced water intoxication has been described during drinking games and initiation ceremonies, but this would appear to an unusual cause. Conservative management proved successful in allowing this girl to recover without sequelae. PMID:21873727

    Determination of aerial camera shutter and aperture settings to produce consistently high-quality aerial photographs is a task complicated by numerous variables. Presented in this article are brief discussions of each variable and specific data which may be used for the systematic control of each. The variables discussed include sunlight, aircraft altitude, subject and season, film speed, and optical system. Data which may be used as a base reference are included, and encompass two sets of sensitometric specifications for two film-chemistry processes along with camera-aircraft parameters, which have been established and used to produce good exposures. Information contained here may be used to design and implement an exposure-determination system for aerial photography.

    Scales for photography provide a geometrical reference in the photographic documentation of a crime scene, pattern, or item of evidence. The ABFO No. 2 Standard Reference Scale (1) is used by the forensic science community as an accurate reference scale. We investigated the overall accuracy of the major centimeter graduations, internal/external diameters of the circles, error in placement of the circle centers, and leg perpendicularity. Four vendors were selected for the scales, and the features were measured on a vision-based coordinate measurement system. The scales were well within the specified tolerance for the length graduations. After 4 years, the same scales were measured to determine what change could be measured. The scales demonstrated acceptable stability in the scale length and center-to-center measurements; however, the perpendicularity exhibited change. The study results indicate that scale quality checks using certified metal rulers are good practice. PMID:27404626

    This paper reports further progress on photography of faint astronomical and geophysical phenomena accomplished during the recent Apollo missions. Command module pilots have been able to photograph such astronomical objects as the solar corona, zodiacal light-corona transition region, lunar libration region, and portions of the Milky Way. The methods utilized for calibration of the film by adaptation of the High Altitude Observatory sensitometer are discussed. Kodak 2485 high-speed recording film was used in both 35-mm and 70-mm formats. The cameras used were Nikon f/1.2 55-mm focal length and Hasselblad f/2.8 80-mm focal length. Preflight and postflight calibration exposures were included on both the flight and control films, corresponding to luminances extending from the inner solar corona to as faint as 1/10 of the luminance of the light of the night sky. The photographs obtained from unique vantage points available during lunar orbit are discussed.

    Since astronomers began to use photography on a scientific basis, a number of pictures of the Milky Way band, or large parts thereof, has been made. Barnard (1890, 1927) produced a series of fine Milky Way photos. Later attempts by Rodgers, Whiteoak et al. (1960), Schmidt-Kaler and Schlosser (1972), Sivan (1974) and others resulted in impressive pictures, either in the form of panoramas or extreme wide-field views, mostly in weil defined (narrow) spectral bands. The most famous depietion of the Milky Way, however, is not a photograph but a drawing made by hand. This was made by M. and T. Keskula at Lund Observatory, and it has become the standard representation of the Milky Way band in textbooks.

    Burton, Christopher; Mitchell, Jerry T; Cutter, Susan L

    2011-07-01

    Hurricane Katrina of August 2005 had extensive consequences for the state of Mississippi in the United States. Widespread infrastructure and property damage, massive social dislocation, and ecological loss remain among the many challenges faced by communities as they work towards 'normalcy'. This study employs repeat photography to understand differential recovery from Hurricane Katrina in Mississippi. Revealing change with conventional landscape photography, a process known as repeat photography, is common in the natural sciences. Simply stated, repeat photography is the practice of re-photographing the same scene as it appears in an earlier photograph. Photographs were taken at 131 sites every six months over a three-year period. Each photograph was assigned a recovery score and a spatially interpolated recovery surface was generated for each time period.

    PubMed Central

    Ashique, KT; Kaliyadan, Feroze

    2011-01-01

    Clinical photography of hair disorders is an extension of photography in dermatology practice. Some points should be kept in mind while taking images of the hair and hair bearing areas in view of the reflection of light and the subsequent glare that may spoil the result. For documentation of most conditions of the hair, the same general rules of dermatological photography apply. The correct lighting is the most important aspect of clinical photography in trichology practice and can be achieved by reflected light than direct light. Special care should be taken in conditions requiring serial images to document progress/response to treatment and the most important factor in this context is consistency with respect to patient positioning, lighting, camera settings and background. Dermoscopy/trichoscopy can also be incorporated in clinical practice for image documentation. PMID:21769229

    2015-04-01

    Medical photographic image capture and data management has undergone a rapid and compelling change in complexity over the last 20 years. This is because of multiple factors, including significant advances in ease of photograph capture, alongside an evolution of mechanisms of data portability/dissemination, combined with governmental focus on health information privacy. Literature to guide medical, legal, governmental and business professionals when dealing with issues related to medical photography is virtually nonexistent. Herein, we will address the breadth of uses of medical photography, device properties/specific devices utilised for image capture, methods of data transfer and dissemination and patient perceptions and attitudes regarding photography in a medical setting. In addition, we will address the legal implications, including legal precedent, copyright and privacy law, informed consent, protected health information and the Health Insurance Portability and Accountability Act (HIPAA), as they pertain to medical photography.

    1974-01-01

    The ability of multiband photography to discriminate sedimentary rocks is investigated. Measurements showed that there is a large natural variation in the band reflectance of rock formations and that the differences in the contrast ratios for different Wratten filters is small, making it statistically impossible to select a set of best bands from in situ reflectance measurements. It is concluded that the designed multiband photography concept is not a practical method for improving sedimentary-rock discrimination capabilities.

    Dental technology is rapidly affecting the treatment options available to patients. Dental lasers are an innovative technology for both hard- and soft-tissue treatment applications. The ability to recontour soft tissues efficiently and predictably with immediate hemostatsis and minimal postoperative sequelae is of value to both the dentist and the patient. This article reviews the principles of dental lasers, criteria to consider when selecting a dental laser, and some of their clinical applications.

    Nuzzolese, E; Lepore, M M; Cukovic-Bagic, I; Montagna, F; Di Vella, G

    2008-12-01

    The scientific literature contains very little about the role of the dental hygienist/therapist in the specific areas of forensic investigations and collection of evidence. The authors examine how the contribution of a highly qualified dental hygienist can be particularly helpful during human forensic identification operations and non-accidental traumas like domestic violence, child abuse, neglect and bitemarks. Forensic dental identification of human remains is a highly complex multidisciplinary challenge. It requires the involvement of several professionals who are expert in forensic science. Among these, one or more adequately trained dental hygienists could be involved. Dental hygienists/therapists may also be asked to record cutaneous lesions in two different situations. The first may be the dental office where she/he may detect oval, elliptic, or semicircular lesions on the skin of the uncovered neck, shoulder and arms of a patient. The second is the crime scene or the morgue (if one is involved), which may require a visit by the forensic odontologist called by the medical examiner or the coroner to perform an odontological autopsy. The purpose of our study is to highlight procedures that should be followed by the dental hygienist/therapist in collecting forensic information in the above-mentioned scenarios. As a valuable resource, the authors recommend training of dental hygienists in the area of forensic sciences, with particular attention to information technology and photography. PMID:19145795

    Dental caries continues to be the most prevalent bacteria-mediated non-contagious disease of humankind. Dental professionals assert the disease can be explained by poor oral hygiene and a diet rich in sugars but this does not account for caries free individuals exposed to the same risk factors. In order to test the hypothesis that amount of amelogenin during enamel development can influence caries susceptibility, we generated multiple strains of mice with varying levels of available amelogenin during dental development. Mechanical tests showed that dental enamel developed with less amelogenin is "weaker" while the dental enamel of animals over-expressing amelogenin appears to be more resistant to acid dissolution.

    Whenever blunt or sharp forces are used in a crime, analysis of bloodstain pattern distribution may provide important information for the reconstruction of happenings. Thereby, attention should be paid to both the crime scene and the clothes of everyone involved in the crime. On dark textiles, though, it is difficult or even impossible for the human eye to detect bloodstains because of the low contrast to the background. However, in the near infrared wavelength range, contrast is considerably higher. Many textiles reflect light beyond a wavelength of 830 nm and thus appear light-colored, whereas blood absorbs the light and appears dark. In our studies, a D7000 NIKON reflex camera modified for infrared photography produced high-resolution photographs visualizing even very small spatter stains on dark textiles. The equipment can be used at any crime scene or lab and provides immediately available and interpretable images. Thus, important findings can be obtained at an early stage of police investigations, as two examples (homicide and attempted homicide) illustrate. PMID:26932868

    The field of photography began a metamorphosis several years ago which promises to fundamentally change how images are captured, transmitted, and output. At this time the metamorphosis is still in the early stages, but already new processes, hardware, and software are allowing many individuals and organizations to explore the entry of imaging into the information revolution. Exploration at this time is prerequisite to leading expertise in the future, and a number of branches at LaRC have ventured into electronic and digital imaging. Their progress until recently has been limited by two factors: the lack of an integrated approach and the lack of an electronic photographic capability. The purpose of the research conducted was to address these two items. In some respects, the lack of electronic photographs has prevented application of an integrated imaging approach. Since everything could not be electronic, the tendency was to work with hard copy. Over the summer, the Photographics Section has set up an Electronic Photography Laboratory. This laboratory now has the capability to scan film images, process the images, and output the images in a variety of forms. Future plans also include electronic capture capability. The current forms of image processing available include sharpening, noise reduction, dust removal, tone correction, color balancing, image editing, cropping, electronic separations, and halftoning. Output choices include customer specified electronic file formats which can be output on magnetic or optical disks or over the network, 4400 line photographic quality prints and transparencies to 8.5 by 11 inches, and 8000 line film negatives and transparencies to 4 by 5 inches.

    Forensic photographs not only need to be unaltered and authentic and capture context-relevant images, along with certain minimum requirements for image sharpness and information density, but color accuracy also plays an important role, for instance, in the assessment of injuries or taphonomic stages, or in the identification and evaluation of traces from photos. The perception of color not only varies subjectively from person to person, but as a discrete property of an image, color in digital photos is also to a considerable extent influenced by technical factors such as lighting, acquisition settings, camera, and output medium (print, monitor). For these reasons, consistent color accuracy has so far been limited in digital photography. Because images usually contain a wealth of color information, especially for complex or composite colors or shades of color, and the wavelength-dependent sensitivity to factors such as light and shadow may vary between cameras, the usefulness of issuing general recommendations for camera capture settings is limited. Our results indicate that true image colors can best and most realistically be captured with the SpyderCheckr technical calibration tool for digital cameras tested in this study. Apart from aspects such as the simplicity and quickness of the calibration procedure, a further advantage of the tool is that the results are independent of the camera used and can also be used for the color management of output devices such as monitors and printers. The SpyderCheckr color-code patches allow true colors to be captured more realistically than with a manual white balance tool or an automatic flash. We therefore recommend that the use of a color management tool should be considered for the acquisition of all images that demand high true color accuracy (in particular in the setting of injury documentation).

    Nightscape photos and timelapse videos, where the Earth & sky are framed together with an astronomical purpose, support the dark skies activities by improving public awareness. TWAN or The World at Night program (www.twanight.org) presents the world's best collection of such landscape astrophotos and aims to introduce the night sky as a part of nature, an essential element of our living environment besides being the astronomers lab. The nightscape images also present views of our civilizations landmarks, both natural and historic sites, against the night-time backdrop of stars, planets, and celestial events. In this context TWAN is a bridge between art, science and culture.TWAN images contribute to programs such as the Dark Sky Parks by the International Dark Sky Association or Starlight reserves by assisting local efforts in better illustrating their dark skies and by producing stunning images that not only educate the local people on their night sky heritage also communicate with the governments that are responsible to support the dark sky area.Since 2009 TWAN organizes the world's largest annual photo contest on nightscape imaging, in collaboration with the Dark Skies Awareness, National Optical Astronomy Observatory, and Astronomers Without Borders. The International Earth & Sky Photo Contest promotes the photography that documents the beauty of natural skies against the problem of light pollution. In 2014 the entries received from about 50 countries and the contest result news was widely published in the most popular sources internationally.*Babak A.

  19. Image modulation in corona discharge photography.

    PubMed

    Pehek, J O; Kyler, H J; Faust, D L

    1976-10-15

    Photographic images obtained by the Kirlian technique are principally a record of corona activity during an exposure interval. Most of the variations in the images of the corona of a living subject who is in contact with the photographic film can be accounted for by the presence of moisture on or within the subject's surface. During exposure, moisture is transferred from the subject to the emulsion surface of the photographic film and causes an alteration of the electric charge pattern on the film, hence the electric field at the surface of the subject. As a result, large variations in the density of corona images, corona streamer trajectories, and image coloration can be brought about. The radial extent of corona images--that is, the range of corona streamers--is an inverse function of the resistance in the circuit formed by the high-voltage supply, the subject, and the film-electrode configuration. This is because the voltage at which corona is initiated is dependent on the rate of rise of the voltage impressed between the subject and the electrode, and the rate of rise is governed by the applied voltage waveform and the voltage drop across the resistance. The range of streamers is proportional to the corona onset voltage. However, we have not seen any influence of large changes in skin resistance on streamer range. Presumably, this is due to the shunting effect of skin capacitance. In general, the photographic response to moisture suggests that corona discharge photography may be useful in the detection and quantification of moisture in animate and inanimate specimens through the orderly modulation of the image due to various levels of moisture.

    Reports of in-hospital bereavement photography focus largely on stillborns and neonates. Empiric data regarding the implementation of bereavement photography in pediatrics beyond the neonatal period and the impact of such programs on healthcare professionals (HCPs) is lacking. We describe the implementation of a pediatric intensive care unit (PICU) bereavement photography program and use questionnaire data from HCPs to describe HCPs’ reflections on the program and to identify program barriers. From July, 2007 through April, 2010 families of 59 (36%) of the 164 patients who died in the PICU participated in our bereavement photography program. Forty questionnaires from 29 HCPs caring for 39 participating patients/families indicated that families seemed grateful for the service (n=34, 85%) and that the program helped HCPs feel better about their role (n=30, 70%). Many HCPs disagreed that the program consumed too much of his/her time (n=34, 85%) and that the photographer made his/her job difficult (n=37, 92.5%). Qualitative analysis of responses to open ended questions revealed four categories: the program’s general value; positive aspects of the program; negative aspects of the program; and suggestions for improvements. Implementing bereavement photography in the PICU is feasible though some barriers exist. HCPs may benefit from such programs. PMID:24520925

    High-quality medical photography plays an important role in teaching and demonstrating the functional capacity of the hands as well as in medicolegal documentation. Obtaining standardized, high-quality photographs is now an essential component of many surgery practices. The importance of standardized photography in facial and cosmetic surgery has been well documented in previous studies, but no studies have thoroughly addressed the details of photography for hand surgery. In this paper, we provide a set of guidelines and basic camera concepts for different scenarios to help hand surgeons obtain appropriate and informative high-quality photographs. A camera used for medical photography should come equipped with a large sensor size and an optical zoom lens with a focal length ranging anywhere from 14 to 75 mm. In a clinic or office setting, we recommend 6 standardized views of the hand and 4 views for the wrist; additional views should be taken for tendon ruptures, nerve injuries, or other deformities of the hand. For intraoperative pictures, the camera operator should understand the procedure and pertinent anatomy in order to properly obtain high-quality photographs. When digital radiographs are not available and radiographic film must be photographed, it is recommended to reduce the exposure and change the color mode to black and white to obtain the best possible pictures. The goal of medical photography is to present the subject in an accurate and precise fashion.

  4. What is dental ecology?

    Cuozzo, Frank P; Sauther, Michelle L

    2012-06-01

    Teeth have long been used as indicators of primate ecology. Early work focused on the links between dental morphology, diet, and behavior, with more recent years emphasizing dental wear, microstructure, development, and biogeochemistry, to understand primate ecology. Our study of Lemur catta at the Beza Mahafaly Special Reserve, Madagascar, has revealed an unusual pattern of severe tooth wear and frequent tooth loss, primarily the result of consuming a fallback food for which these primates are not dentally adapted. Interpreting these data was only possible by combining our areas of expertise (dental anatomy [FC] and primate ecology [MS]). By integrating theoretical, methodological, and applied aspects of both areas of research, we adopted the term "dental ecology"-defined as the broad study of how teeth respond to the environment. Specifically, we view dental ecology as an interpretive framework using teeth as a vehicle for understanding an organism's ecology, which builds upon earlier work, but creates a new synthesis of anatomy and ecology that is only possible with detailed knowledge of living primates. This framework includes (1) identifying patterns of dental pathology and tooth use-wear, within the context of feeding ecology, behavior, habitat variation, and anthropogenic change, (2) assessing ways in which dental development and biogeochemical signals can reflect habitat, environmental change and/or stress, and (3) how dental microstructure and macro-morphology are adapted to, and reflect feeding ecology. Here we define dental ecology, provide a short summary of the development of this perspective, and place our new work into this context.

The aim is to inform about current developments and to examine, how access to qualified dental hygiene care might be improved and how professional challenges might be met. For an international study on dental hygiene, secondary source data were obtained from members of the House of Delegates of the International Federation of Dental Hygienists (IFDH) or by fax and e-mail from experts involved in the national professional and educational organization of dental hygiene in non-IFDH member countries, such as Slovakia. Responses were followed-up by interviews, e-mail correspondence, visits to international universities, and a review of supporting studies and reference literature. Results show that the introduction of dental hygiene in Slovakia in 1992 was inspired by the delivery of preventive care in Switzerland. Initiating local dentists and dental hygienists strive to attain a high educational level, equitable to that of countries in which dental hygiene has an established tradition of high quality care. Low access to qualified dental hygiene care may be a result of insufficient funding for preventive services, social and cultural lack of awareness of the benefits of preventive care, and of limitations inherent in the legal constraints preventing unsupervised dental hygiene practice. These may be a result of gender politics affecting a female-dominated profession and of a perception that dental hygiene is auxiliary to dental care. International comparison show that of all Eastern European countries, the dental hygiene profession appears most advanced in Slovakia. This is expressed in high evidence-based academic goals, in extensive work with international consultants from the Netherlands and Switzerland, in annual congresses of high professional quality, and in the establishment of a profession, which has not been introduced in all Western EU countries

  8. Determining density of maize canopy. 1: Digitized photography

    NASA Technical Reports Server (NTRS)

    Stoner, E. R.; Baumgardner, M. F.; Swain, P. H.

    1972-01-01

    The relationship between different densities of maize (Zea mays L.) canopies and the energy reflected by these canopies was studied. Field plots were laid out, representing four growth stages of maize, on a dark soil and on a very light colored surface soil. Spectral and spatial data were obtained from color and color infrared photography taken from a vertical distance of 10 m above the maize canopies. Estimates of ground cover were related to field measurements of leaf area index. Ground cover was predicted from leaf area index measurements by a second order equation. Color infrared photography proved helpful in determining the density of maize canopy on dark soils. Color photography was useful for determining canopy density on light colored soils. The near infrared dye layer is the most valuable in canopy density determinations.

  9. Digital data from shuttle photography: The effects of platform variables

    NASA Technical Reports Server (NTRS)

    Davis, Bruce E.

    1987-01-01

    Two major criticisms of using Shuttle hand held photography as an Earth science sensor are that it is nondigital, nonquantitative and that it has inconsistent platform characteristics, e.g., variable look angles, especially as compared to remote sensing satellites such as LANDSAT and SPOT. However, these criticisms are assumptions and have not been systematically investigated. The spectral effects of off-nadir views of hand held photography from the Shuttle and their role in interpretation of lava flow morphology on the island of Hawaii are studied. Digitization of photography at JSC and use of LIPS image analysis software in obtaining data is discussed. Preliminary interpretative results of one flow are given. Most of the time was spent in developing procedures and overcoming equipment problems. Preliminary data are satisfactory for detailed analysis.

    Medical photography is the state of the art for the documentation of dermatological disease. Experienced photographers take pictures of the most typical skin lesions in order to assist the clinician in assessing disease morphology and activity. In this study, we present 6 individuals with a variety of dermatoses and the expression of the patients’ emotions. The patients were asked to show their diseased skin and to present typically involved areas in the respective disease. The feelings expressed by their body movements and positions are viewed and interpreted. The patients’ history will be reported retrospectively. The aim of the report is to show that the art of medical photography does not only document skin lesions but also the disease burden and the associated impairment of quality of life. Moreover, dermatologic photography is a sensitive intervention for patients viewed in the light of teaching and patient care. PMID:27790112

  15. Case based dental radiology.

    PubMed

    Niemiec, Brook A

    2009-02-01

    Dental radiology is quickly becoming integral to the standard of care in veterinary dentistry. This is not only because it is critical for proper patient care, but also because client expectations have increased. Furthermore, providing dental radiographs as a routine service can create significant practice income. This article details numerous conditions that are indications for dental radiographs. As you will see, dental radiographs are often critical for proper diagnosis and treatment. These conditions should not be viewed as unusual; they are present within all of our practices. When you choose not to radiograph these teeth, you leave behind painful pathology. Utilizing the knowledge gained from dental radiographs will both improve patient care and increase acceptance of treatment recommendations. Consequently, this leads to increased numbers of dental procedures performed at your practice. PMID:19410233

    The application of space and high flight photography to vegetational resources in Arizona is discussed. Ecologically based vegetation-landform and land use maps are prepared. The use of material from the Apollo 9 flight and high flight aerial photography are discussed. Land uses that result in a conversion or strong modification of the natural vegetation are presented. The vegetation-landform units have an ecological basis and are meaningful from a land use point of view because they identify areas with unique potentials or limitations for use or development under various land uses. Examples of these relationships are given.

    1981-01-01

    Expanded polyethylene foam (Plastazote) is used in the treatment of rheumatoid, diabetic, and leprotic foot disorders. This paper describes a diagnostic use for this material. Two photographic techniques combine to give vivid and quantitative representations of foot deformities which are easily applicable to clinical use. Relief photography uses illumination to create an illusion of solidity in a 2-dimensional photography. Stereophotogrammetry produces contour plots from stereopairs of photographs of the Plastazote footprint. After use the impressions are trimmed and slipped into the patient's shoes in the same way as any other foam insole. Images PMID:7469529

    2005-01-01

    A review of the most commonly used dental age estimating techniques is generated. The most important issue for the forensic odontologist involved in dental age estimation is to employ as many of these methods as possible by performing repetitive measurements and calculations of different age-related parameters. That is the only way in order to try and establish reliable dental age estimations. In particular, a special chapter is attributed to the complex problem of determining the age of majority.

    2010-01-01

    Among various dental materials and their successful applications, a dental implant is a good example of the integrated system of science and technology involved in multiple disciplines including surface chemistry and physics, biomechanics, from macro-scale to nano-scale manufacturing technologies and surface engineering. As many other dental materials and devices, there are crucial requirements taken upon on dental implants systems, since surface of dental implants is directly in contact with vital hard/soft tissue and is subjected to chemical as well as mechanical bio-environments. Such requirements should, at least, include biological compatibility, mechanical compatibility, and morphological compatibility to surrounding vital tissues. In this review, based on carefully selected about 500 published articles, these requirements plus MRI compatibility are firstly reviewed, followed by surface texturing methods in details. Normally dental implants are placed to lost tooth/teeth location(s) in adult patients whose skeleton and bony growth have already completed. However, there are some controversial issues for placing dental implants in growing patients. This point has been, in most of dental articles, overlooked. This review, therefore, throws a deliberate sight on this point. Concluding this review, we are proposing a novel implant system that integrates materials science and up-dated surface technology to improve dental implant systems exhibiting bio- and mechano-functionalities.

    This study evaluated color variability in the A hue between the VITA Classical (VITA Zahnfabrik) shade guide and four other VITA-coded ceramic shade guides using a Canon EOS 60D camera and software (Photoshop CC, Adobe). A total of 125 photographs were taken, 5 per shade tab for each of 5 shades (A1 to A4) from the following shade guides: VITA Classical (control), IPS e.max Ceram (Ivoclar Vivadent), IPS d.SIGN (Ivoclar Vivadent), Initial ZI (GC), and Creation CC (Creation Willi Geller). Photos were processed with Adobe Photoshop CC to allow standardized evaluation of hue, chroma, and value between shade tabs. None of the VITA-coded shade tabs fully matched the VITA Classical shade tab for hue, chroma, or value. The VITA-coded shade guides evaluated herein showed an overall unmatched shade in all tabs when compared with the control, suggesting that shade selection should be made using the guide produced by the manufacturer of the ceramic intended for the final restoration.

  16. Filling gaps in cultural heritage documentation by 3D photography

    2015-08-01

    This contribution promotes 3D photography as an important tool to obtain objective object information. Keeping mainly in mind World Heritage documentation as well as Heritage protection, it is another intention of this paper, to stimulate the interest in applications of 3D photography for professionals as well as for amateurs. In addition this is also an activity report of the international CIPA task group 3. The main part of this paper starts with "Digging the treasure of existing international 3D photography". This does not only belong to tangible but also to intangible Cultural Heritage. 3D photography clearly supports the recording, the visualization, the preservation and the restoration of architectural and archaeological objects. Therefore the use of 3D photography in C.H. should increase on an international level. The presented samples in 3D represent a voluminous, almost partly "forgotten treasure" of international archives for 3D photography. The next chapter is on "Promoting new 3D photography in Cultural Heritage". Though 3D photographs are a well-established basic photographic and photogrammetric tool, even suited to provide "near real" documentation, they are still a matter of research and improvement. Beside the use of 3D cameras even single lenses cameras are very much suited for photographic 3D documentation purposes in Cultural Heritage. Currently at the Faculty of Civil Engineering of the University of Applied Sciences Magdeburg-Stendal, low altitude aerial photography is exposed from a maximum height of 13m, using a hand hold carbon telescope rod. The use of this "huge selfie stick" is also an (international) recommendation, to expose high resolution 3D photography of monuments under expedition conditions. In addition to the carbon rod recently a captive balloon and a hexacopter UAV- platform is in use, mainly to take better synoptically (extremely low altitude, ground truth) aerial photography.

    In 2005, Public Act No. 161 (PA 161) was passed in Michigan, allowing dental hygienists to practice in approved public dental prevention programs to provide services for underserved populations while utilizing a collaborative agreement with a supervising dentist. The aims of this study were to assess how well dental and dental hygiene students and faculty members and practicing dental hygienists have been educated about PA 161, what attitudes and knowledge about the act they have, and how interested they are in additional education about it. University of Michigan dental and dental hygiene students and faculty members, students in other Michigan dental hygiene programs, and dental hygienists in the state were surveyed. Respondents (response rate) were 160 dental students (50%), 63 dental hygiene students (82%), 30 dental faculty members (26%), and 12 dental hygiene faculty members (52%) at the University of Michigan; 143 dental hygiene students in other programs (20%); and 95 members of the Michigan Dental Hygienists' Association (10%). The results showed that the dental students were less educated about PA 161 than the dental hygiene students, and the dental faculty members were less informed than the dental hygiene faculty members and dental hygienists. Responding dental hygiene faculty members and dental hygienists had more positive attitudes about PA 161 than did the students and dental faculty members. Most of the dental hygiene faculty members and dental hygienists knew a person providing services in a PA 161 program. Most dental hygiene students, faculty members, and dental hygienists wanted more education about PA 161. Overall, the better educated about the program the respondents were, the more positive their attitudes, and the more interested they were in learning more. PMID:27587574

  20. Faces and Photography in 19th-Century Visual Science.

    PubMed

    Wade, Nicholas J

    2016-09-01

    Reading faces for identity, character, and expression is as old as humanity but representing these states is relatively recent. From the 16th century, physiognomists classified character in terms of both facial form and represented the types graphically. Darwin distinguished between physiognomy (which concerned static features reflecting character) and expression (which was dynamic and reflected emotions). Artists represented personality, pleasure, and pain in their paintings and drawings, but the scientific study of faces was revolutionized by photography in the 19th century. Rather than relying on artistic abstractions of fleeting facial expressions, scientists photographed what the eye could not discriminate. Photography was applied first to stereoscopic portraiture (by Wheatstone) then to the study of facial expressions (by Duchenne) and to identity (by Galton and Bertillon). Photography opened new methods for investigating face perception, most markedly with Galton's composites derived from combining aligned photographs of many sitters. In the same decade (1870s), Kühne took the process of photography as a model for the chemical action of light in the retina. These developments and their developers are described and fixed in time, but the ideas they initiated have proved impossible to stop. PMID:27146124

    Astronaut photography acquired from the International Space Station (ISS) using commercial off-the-shelf cameras offers a freely-accessible source for high to very high resolution (4-20 m/pixel) visible-wavelength digital data of Earth. Since ISS Expedition 1 in 2000, over 373,000 images of the Earth-Moon system (including land surface, ocean, atmospheric, and lunar images) have been added to the Gateway to Astronaut Photography of Earth online database (http://eol.jsc.nasa.gov ). Handheld astronaut photographs vary in look angle, time of acquisition, solar illumination, and spatial resolution. These attributes of digital astronaut photography result from a unique combination of ISS orbital dynamics, mission operations, camera systems, and the individual skills of the astronaut. The variable nature of astronaut photography makes the dataset uniquely useful for archaeological applications in comparison with more traditional nadir-viewing multispectral datasets acquired from unmanned orbital platforms. For example, surface features such as trenches, walls, ruins, urban patterns, and vegetation clearing and regrowth patterns may be accentuated by low sun angles and oblique viewing conditions (Fig. 1). High spatial resolution digital astronaut photographs can also be used with sophisticated land cover classification and spatial analysis approaches like Object Based Image Analysis, increasing the potential for use in archaeological characterization of landscapes and specific sites.

  7. Faces and Photography in 19th-Century Visual Science.

    PubMed

    Wade, Nicholas J

    2016-09-01

    Reading faces for identity, character, and expression is as old as humanity but representing these states is relatively recent. From the 16th century, physiognomists classified character in terms of both facial form and represented the types graphically. Darwin distinguished between physiognomy (which concerned static features reflecting character) and expression (which was dynamic and reflected emotions). Artists represented personality, pleasure, and pain in their paintings and drawings, but the scientific study of faces was revolutionized by photography in the 19th century. Rather than relying on artistic abstractions of fleeting facial expressions, scientists photographed what the eye could not discriminate. Photography was applied first to stereoscopic portraiture (by Wheatstone) then to the study of facial expressions (by Duchenne) and to identity (by Galton and Bertillon). Photography opened new methods for investigating face perception, most markedly with Galton's composites derived from combining aligned photographs of many sitters. In the same decade (1870s), Kühne took the process of photography as a model for the chemical action of light in the retina. These developments and their developers are described and fixed in time, but the ideas they initiated have proved impossible to stop.

It is now time to revisit this issue. Much has changed since the last workforce review in England and Wales, and the rate of change is in all probability set to increase. First, at the time of writing this paper the momentous step of including dental care professionals (DCPs) on General Dental Council (GDC) registers in the United Kingdom has recently been completed. Second, the Scope of Practice of all dental professionals has been under consultation by the General Dental Council, and research evidence suggests that greater use should be made of skill-mix in the dental team. Third, within England, Lord Darzi has just published the 'Final Report of the NHS Next Stage Review', which emphasises 'quality care' and 'team-working' as key features of healthcare; this report was accompanied by an important document entitled 'A High Quality Workforce', in which plans for local workforce planning within the NHS are outlined, placing responsibilities at national, local and regional levels. Fourth, policy makers across the UK are wrestling with addressing oral health needs, promoting health and facilitating access to dental care, all of which have implications for the nature and shape of the dental workforce. Fifth, with the impact of globalisation and European policies we are net gainers of dentists as well as having more in training. Sixth, although there have been reviews and policy initiatives by regulatory, professional and other bodies in support of shaping the dental workforce, there has been little serious consideration of skill-mix and funding mechanisms to encourage team-working.

  2. What is dental ecology?

    PubMed

    Cuozzo, Frank P; Sauther, Michelle L

    2012-06-01

    Teeth have long been used as indicators of primate ecology. Early work focused on the links between dental morphology, diet, and behavior, with more recent years emphasizing dental wear, microstructure, development, and biogeochemistry, to understand primate ecology. Our study of Lemur catta at the Beza Mahafaly Special Reserve, Madagascar, has revealed an unusual pattern of severe tooth wear and frequent tooth loss, primarily the result of consuming a fallback food for which these primates are not dentally adapted. Interpreting these data was only possible by combining our areas of expertise (dental anatomy [FC] and primate ecology [MS]). By integrating theoretical, methodological, and applied aspects of both areas of research, we adopted the term "dental ecology"-defined as the broad study of how teeth respond to the environment. Specifically, we view dental ecology as an interpretive framework using teeth as a vehicle for understanding an organism's ecology, which builds upon earlier work, but creates a new synthesis of anatomy and ecology that is only possible with detailed knowledge of living primates. This framework includes (1) identifying patterns of dental pathology and tooth use-wear, within the context of feeding ecology, behavior, habitat variation, and anthropogenic change, (2) assessing ways in which dental development and biogeochemical signals can reflect habitat, environmental change and/or stress, and (3) how dental microstructure and macro-morphology are adapted to, and reflect feeding ecology. Here we define dental ecology, provide a short summary of the development of this perspective, and place our new work into this context. PMID:22610892

    1995-09-01

    The aim of this investigation is to provide information about the financial status of dental students enrolled on the Bachelor of Dental Surgery degree course at the University of Birmingham. All undergraduate dental students enrolled during the academic year 1993-94 were asked to participate in the study. The pre-tested questionnaire, which was given to all students, covered personal details, expenditure levels, income, loans, overdrafts, use of government schemes ('top-up loans'), and so on. The questionnaire was completed by 115 dental students (response rate 47%). The results showed that dental students' debts increased each year throughout the course. A top-up loan (range 700 Pounds-850 Pounds) had been taken out by 36% of students. The financial status of 9% of students was severe enough to warrant their eligibility for awards from access funds. Credit cards were possessed by 52% of the surveyed students, and although only half of these owed money, 22% owed between 500 Pounds and 2000 Pounds. Personal overdrafts were held by 56% of respondents. A total of 17% of students engaged in weekly part-time employment. The average debt for final year students was 1200 Pounds. Dental students' estimates of the level of debt they were likely to incur was greater than the actual debt presently experienced by final year students. In conclusion, this preliminary study showed that most dental students incur debt during their undergraduate course and that this debt increases during the course.

  6. Economic impact of dental hygienists on solo dental practices.

    PubMed

    Lazar, Vickie F; Guay, Albert H; Beazoglou, Tryfon J

    2012-08-01

    The fact that a significant percentage of dentists employ dental hygienists raises an important question: Are dental practices that utilize a dental hygienist structurally and operationally different from practices that do not? This article explores differences among dental practices that operate with and without dental hygienists. Using data from the American Dental Association's 2003 Survey of Dental Practice, a random sample survey of U.S. dentists, descriptive statistics were used to compare selected characteristics of solo general practitioners with and without dental hygienists. Multivariate regression analysis was used to estimate the effect of dental hygienists on the gross billings and net incomes of solo general practitioners. Differences in practice characteristics--such as hours spent in the practice and hours spent treating patients, wait time for a recall visit, number of operatories, square feet of office space, net income, and gross billings--were found between solo general practitioners who had dental hygienists and those who did not. Solo general practitioners with dental hygienists had higher gross billings. Higher gross billings would be expected, as would higher expenses. However, net incomes of those with dental hygienists were also higher. In contrast, the mean waiting time for a recall visit was higher among dentists who employed dental hygienists. Depending on personal preferences, availability of qualified personnel, etc., dentists who do not employ dental hygienists but have been contemplating that path may want to further research the benefits and opportunities that may be realized.

  7. Noise-optimal capture for coded exposure photography

    NASA Astrophysics Data System (ADS)

    Huang, Kuihua; Zhang, Jun; Li, Guohui

    2012-09-01

    Searching for the optimal shutter sequence is the key problem in coded exposure photography. Previous shutter sequence searching methods focus on the point spread function estimation and invertibility, and ignore the influence of the scene light level or avoid noise calibration of real cameras. For practical purposes, we address the problem of finding an optimal shutter sequence for coded exposure photography in the presence of photon noise. We analyze the effect of photon noise on the optimal shutter sequence in terms of deconvolution noise and derive analytic formulas. We show that Raskar's code is a special case of our analysis. Based on noise calibration of the coded exposure camera, an effective fitness function is proposed, and using our carefully designed genetic algorithm, we obtain the optimal shutter sequence with little running time. Experimental results with synthetic and real data demonstrate the advantage of our approach compared to the state of the art approach.

    1972-01-01

    The Apollo program has been the most complex exploration ever attempted by man, requiring extensive research, development, and engineering in most of the sciences before the leap through space could begin. Photography has been used at each step of the way to document the efforts and activities, isolate mistakes, reveal new phenomena, and to record much that cannot be seen by the human eye. At the same time, the capabilities of photography were extended because of the need of meeting space requirements. The results of this work have been applied to community planning and ecology, for example, as well as to space and engineering. Special uses of standard equipment, modifications and new designs, as well as film combinations that indicate actual or potential ecological problems are described.

  9. Clinical photography and patient rights: the need for orthopraxy.

    PubMed

    Berle, I

    2008-02-01

    The increasing use of digital image recording devices, whether they are digital cameras or mobile phone cameras, has democratised clinical photography in the UK. However, when non-professional clinical photographers take photographs of patients the issues of consent and confidentiality are either ignored or given scant attention. Whatever the status of the clinician, the taking of clinical photographs must be practised within the context of a professional etiquette. Best practice recognises the need for informed consent and the constraints associated with confidentiality. Against the background of the poverty of the current discourse of these issues, as presented during the Valentine GMC Fitness to Practice hearing, the paper considers the need for orthopraxy in the use of clinical photography.

    The Live from the Poles project (http://polardiscovery.whoi.edu) is a partnership between polar scientists, media professionals, museums, and the general public. The goal of Live from the Poles is to educate an informal audience about polar science fieldwork using an interactive, photo-driven website and live connections to museum audiences. An embedded media team (photographer and science writer) joins each of the expeditions, reporting on the daily scientific discoveries and life on the ice. This presentation will focus on the use of digital photography not only as a tool to inspire and educate the public, but also as an aid to scientific research. Linder will show photographs from Live from the Poles expeditions to northern Canada, the eastern Arctic Ocean, Antarctica, and Greenland that illustrate the exhilaration and challenges of polar fieldwork. In addition, the presentation will address ways that digital photography, paired with new lightweight GPS receivers, benefit and enhance the research itself.

    2016-07-01

    Mammalian teeth harbour mesenchymal stem cells (MSCs), which contribute to tooth growth and repair. These dental MSCs possess many in vitro features of bone marrow-derived MSCs, including clonogenicity, expression of certain markers, and following stimulation, differentiation into cells that have the characteristics of osteoblasts, chondrocytes and adipocytes. Teeth and their support tissues provide not only an easily accessible source of MSCs but also a tractable model system to study their function and properties in vivo In addition, the accessibility of teeth together with their clinical relevance provides a valuable opportunity to test stem cell-based treatments for dental disorders. This Review outlines some recent discoveries in dental MSC function and behaviour and discusses how these and other advances are paving the way for the development of new biologically based dental therapies.

    Clinical photography in the field of oculoplastic surgery has many applications. It is possible for clinicians to obtain standardized clinical photographs without a studio. A clinician photographer has the advantage of knowing exactly what to photograph as well as having immediate access to the images. In order to maintain standardization in the photographs, the photographic settings should remain constant. This article covers essential photographic equipment, camera settings, patient pose, and digital asset management. PMID:27630805

    The aim of this study was to evaluate interpretations and the reproducibility of interpretations when looking at colposcopic photographs in a forensic setting, as well as discussing some of the dilemmas and pitfalls of forensic colposcopic photography. A total of 316 colposcopic photographs from 51 women taken on three occasions following consensual sexual intercourse, and 78 colposcopic photographs from 39 rape victims, were evaluated by four different observers. Photographs were taken in the same setting, by the same group of investigators, before and after application of toluidine blue dye. The overall Kappa-value for the four observers' judgment of lesion vs. no lesion was 0.41 which can be interpreted as moderate agreement. Intra-observer agreement was calculated for two of the observers looking at photographs with a 10 months' time-gap, and the Kappa-values were 0.41 and 0.52. Positive and negative predictive values of the photographs were 82 and 81 % respectively. This study demonstrates relatively poor reliability of colposcopic photography. Some would argue that this makes colposcopic photography a low-quality method of evaluation and that forensic science should aim for higher standards because of its use in court. Others would argue that as long as the limitations of a scientific method are acknowledged then it is still eligible for use. The moderate agreement and accuracy stresses the need for quality control in the gynecological part of a rape examination. Colposcopic photography also provides a good option for supervision and teaching in an ethically difficult setting. It strengthens the legal rights for both victim and perpetrator.

    The aim of the study was to determine the acceptance and perception of Nigerian patients to medical photography. A self-administered questionnaire was distributed among Nigerian patients attending oral and maxillofacial surgery and plastic surgery clinics of 3 tertiary health institutions. Information requested included patients' opinion about consent process, capturing equipment, distribution and accessibility of medical photographs. The use of non-identifiable medical photographs was more acceptable than identifiable to respondents for all purposes (P = 0.003). Most respondents were favourably disposed to photographs being taken for inclusion in the case note, but opposed to identifiable photographs being used for other purposes most especially in medical websites and medical journals. Female respondents preferred non-identifiable medical photographs to identifiable ones (P = 0.001). Most respondents (78%) indicated that their consent be sought for each of the outline needs for medical photography. Half of the respondents indicated that identifiable photographs may have a negative effect on their persons; and the most commonly mentioned effects were social stigmatization, bad publicity and emotional/psychological effects. Most of the respondents preferred the use of hospital-owned camera to personal camera/personal camera-phone for their medical photographs. Most respondents (67.8%) indicated that they would like to be informed about the use of their photographs on every occasion, and 74% indicated that they would like to be informed of the specific journal in which their medical photographs are to be published. In conclusion, non-identifiable rather than identifiable medical photography is acceptable to most patients in the studied Nigerian environment. The use of personal camera/personal camera-phone should be discouraged as its acceptance by respondents is very low. Judicious use of medical photography is therefore advocated to avoid breach of principle of

    Artificial defoliation in corn was used to explore the usefulness of aerial photography in detecting crop insect infestations. Defoliation on the top of plants was easily detected, while that on the base was less so. Aero infrared film with Wratten 89B filter gave the best results, and morning flights at the scale of 1:15840 are recommended. Row direction, plant growth stage, and time elapse since defoliation were not important factors.

    Objective: This study was conducted to assess the dental arch asymmetry in a Yemeni sample aged (18-25) years. Materials and Methods: The investigation involved clinical examination of 1479 adults; only 253 (129 females, 124 males) out of the total sample were selected to fulfill the criteria for the study sample. Study models were constructed and evaluated to measure mandibular arch dimensions. Three linear distances were utilized on each side on the dental arch: Incisal-canine distance, canine-molar distance and incisal-molar distance, which represent the dental arch segmental measurements. Results: When applying “t-test” at P < 0.05, no significant differences were found between the right and left canine-molar, incisal-canine and incisal-molar distances in both dental arches for both sexes. The greater variation (0.30 mm) was observed between right and left canine-molar distance in the maxillary dental arch in male and the smaller (0.04 mm) in the mandibular dental arch between the right and left canine-molar distance in females. Conclusion: The findings of the present study revealed a symmetrical pattern of dental arches, since the right and left sides showed no statistically significant difference. In general, it can be observed that the measurements related to the central incisors and canines have the widest range of reading and give the impression that the location of central incisor and canines to each other and to other teeth is the strongest factor in determining the dental arch asymmetry.

    1991-01-01

    The National Aerial Photography Program (NAPP) is jointly funded by Federal agencies and States that choose to participate in a 50-50 cost sharing cooperative arrangement. The NAPP is designed to acquire black-and-white (B&W) or color infrared (CIR) photography at a scale of 1:40,000. The status of NAPP flying, now going into the first year of its second 5-year cycle, is reviewed to inform the user community of NAPP's coverage. The resolution, geometric quality and flight parameters are used to estimate the system's cartographic potential to produce orthophotoquads, digital elevation models, topographic maps and digital information to meet national map accuracy standards at 1:12,000 and 1:24,000-scale and serve as a geographic information system resource. Also, a technique is presented to compute the optimum scanning spot size (15 ??m) and storage required for converting the B&W or CIR photography to digital, machine-readable pixel form. The resulting digital NAPP data are suitable for a wide variety of new applications, including use in geographic information systems.

    2006-12-01

    Hope as a concept is commonly described in everyday life and is generally regarded as an important component of health and fulfillment. The importance of hope in relation to people who are marginalised due to illness or other social circumstances has been examined in the research literature. There is, however, a paucity of research addressing the importance of hope for people living with schizophrenia. The authors, in attempting to redress this paucity, identified that participants have difficulty articulating the concept of hope and its meaning to them as individuals. Participant photography was introduced as a research method during the course of the study. This paper presents an overview of the use of participant photography as a method to assist participants to describe their view of hope and its importance. A brief overview of findings are presented and compared with findings derived from traditional interview techniques. Participant photography proved beneficial in facilitating a discussion of hope at a very personal level. The potential ethical implications of this approach are discussed.

    The range of color spaces for possible use with digital photography presents challenges and opportunities for engineers, developers and users of digital cameras. This paper will provide an overview and comparison of a sub-set of these color spaces, with specific consideration for digital photography. Primarily the RGB or red, green and blue color spaces will be compared and although other spaces, such as CIELAB and Yu"v", will be mentioned. Background will be provided with respect to key considerations for design and use of color spaces for digital photography. Data will be presented on color space uniformity using a radial sampling of the OSA Uniform Color Scales and tritanopic confusion lines. In addition, color difference statistics across a fixed sampling will be used to assess the similarity of color spaces and to quantify the resulting error when color spaces are incorrectly assigned. Finally, the gamut shapes will be compared using procrustes analysis of a set of gamut landmark colors. The resulting dendrogram provides a means of visualizing relative similarities of the gamut shapes.

    There are a number of groups across the country working on redesigning introductory physics courses by incorporating physics education research, modeling, and making the courses appeal to students in broader fields. We spent the summer exploring Kirlian photography, a subject that can be understood by students with a basic comprehension of electrostatics but is still questioned by many people in other fields. Kirlian photography's applications have captivated alternative medicine but still requires research from both physics and biology to understand if it has potential as medical tool. We used a simple setup to reproduce the physics that has been done to see if it could be used in an educational setting. I will demonstrate how Kirlian photography can be explained by physics but also how the topic still needs research to completely understand its possible biological applications. By incorporating such a topic into a curriculum, one is able to teach students to explore supposed supernatural phenomena scientifically and to promote research among undergraduate students.

    Dental erosion is a multifactorial condition. The consideration of chemical, biological and behavioral factors is fundamental for its prevention and therapy. Among the biological factors, saliva is one of the most important parameters in the protection against erosive wear. Objective This review discusses the role of salivary factors on the development of dental erosion. Material and Methods A search was undertaken on MEDLINE website for papers from 1969 to 2010. The keywords used in the research were "saliva", "acquired pellicle", "salivary flow", "salivary buffering capacity" and "dental erosion". Inclusion of studies, data extraction and quality assessment were undertaken independently and in duplicate by two members of the review team. Disagreements were solved by discussion and consensus or by a third party. Results Several characteristics and properties of saliva play an important role in dental erosion. Salivary clearance gradually eliminates the acids through swallowing and saliva presents buffering capacity causing neutralization and buffering of dietary acids. Salivary flow allows dilution of the acids. In addition, saliva is supersaturated with respect to tooth mineral, providing calcium, phosphate and fluoride necessary for remineralization after an erosive challenge. Furthermore, many proteins present in saliva and acquired pellicle play an important role in dental erosion. Conclusions Saliva is the most important biological factor affecting the progression of dental erosion. Knowledge of its components and properties involved in this protective role can drive the development of preventive measures targeting to enhance its known beneficial effects. PMID:23138733

    Aim To evaluate the sensitivity and specificity of “fundus on phone’ (FOP) camera, a smartphone based retinal imaging system, as a screening tool for diabetic retinopathy (DR) detection and DR severity in comparison with 7-standard field digital retinal photography. Design Single-site, prospective, comparative, instrument validation study. Methods 301 patients (602 eyes) with type 2 diabetes underwent standard seven-field digital fundus photography with both Carl Zeiss fundus camera and indigenous FOP at a tertiary care diabetes centre in South India. Grading of DR was performed by two independent retina specialists using modified Early Treatment of Diabetic Retinopathy Study grading system. Sight threatening DR (STDR) was defined by the presence of proliferative DR(PDR) or diabetic macular edema. The sensitivity, specificity and image quality were assessed. Results The mean age of the participants was 53.5 ±9.6 years and mean duration of diabetes 12.5±7.3 years. The Zeiss camera showed that 43.9% had non-proliferative DR(NPDR) and 15.3% had PDR while the FOP camera showed that 40.2% had NPDR and 15.3% had PDR. The sensitivity and specificity for detecting any DR by FOP was 92.7% (95%CI 87.8–96.1) and 98.4% (95%CI 94.3–99.8) respectively and the kappa (ĸ) agreement was 0.90 (95%CI-0.85–0.95 p<0.001) while for STDR, the sensitivity was 87.9% (95%CI 83.2–92.9), specificity 94.9% (95%CI 89.7–98.2) and ĸ agreement was 0.80 (95%CI 0.71–0.89 p<0.001), compared to conventional photography. Conclusion Retinal photography using FOP camera is effective for screening and diagnosis of DR and STDR with high sensitivity and specificity and has substantial agreement with conventional retinal photography.

    Objectives: To investigate the potential influence of standard dental materials on dental MRI (dMRI) by estimating the magnetic susceptibility with the help of the MRI-based geometric distortion method and to classify the materials from the standpoint of dMRI. Methods: A series of standard dental materials was studied on a 1.5 T MRI system using spin echo and gradient echo pulse sequences and their magnetic susceptibility was estimated using the geometric method. Measurements on samples of dental materials were supported by in vivo examples obtained in dedicated dMRI procedures. Results: The tested materials showed a range of distortion degrees. The following materials were classified as fully compatible materials that can be present even in the tooth of interest: the resin-based sealer AH Plus® (Dentsply, Maillefer, Germany), glass ionomer cement, gutta-percha, zirconium dioxide and composites from one of the tested manufacturers. Interestingly, composites provided by the other manufacturer caused relatively strong distortions and were therefore classified as compatible I, along with amalgam, gold alloy, gold–ceramic crowns, titanium alloy and NiTi orthodontic wires. Materials, the magnetic susceptibility of which differed from that of water by more than 200 ppm, were classified as non-compatible materials that should not be present in the patient’s mouth for any dMRI applications. They included stainless steel orthodontic appliances and CoCr. Conclusions: A classification of the materials that complies with the standard grouping of materials according to their magnetic susceptibility was proposed and adopted for the purposes of dMRI. The proposed classification can serve as a guideline in future dMRI research. PMID:23610088

    Bowen, Denise M

    2013-01-01

    Dental hygiene is defined as the science and practice of the recognition, treatment and prevention of oral diseases. The history of dental hygiene research is considered in the context of the development of the discipline and an emerging infrastructure. Research-related events supporting the growth and maturation of the profession are considered from the early years to the most recent. The benefits of preventive oral health services provided by dental hygienists have been supported by research, and the practice of dental hygiene has expanded as a result of research findings since its inception 100 years ago. Dental hygienists' engagement in research, however, did not begin until the 1960s as research associates or administrators, primarily with dental researchers as primary investigators. The Journal of Dental Hygiene (JDH) has provided information for dental hygiene practice since 1927, and has been the primary venue for dissemination of dental hygiene research since 1945. Graduate education in dental hygiene at the master's degree level and the work of early dental hygiene researchers led to the first conference on dental hygiene research in 1982. Over 30 years later, dental hygiene has established a meta-paradigm and defined conceptual models, built an initial infrastructure to support research endeavors and contributed much to the development of dental hygiene as a unique discipline. A doctoral degree in the discipline, continued theory-based research, initiatives to foster collaborations between dental hygiene and other researchers and enhanced capabilities to attract funding to support large scale studies are goals that must be attained through the efforts of future researchers to address the needs for additional development in the discipline of dental hygiene. Dental hygiene research supports the growing discipline and its value to society. PMID:24046337

    2008-01-01

    It is often argued that photography's scientific inauguration meaningfully coincided with a shift towards the ideal of mechanical objectivity. Values of disinterestedness and precision were readily attributed to photography and were cherished by the emerging field of neurology as well. However, after the publication of the first neuroanatomical atlas to contain photographs, Jules Bernard Luys' Iconographie Photographique des Centres Nerveux (1873), the use of photography in macroscopic neuroanatomy remained rare. The present article sketches this largely overlooked terrain of investigation and will expand on why in macroscopical neuroanatomy photography failed to offer a satisfactory alternative to drawing or engraving.

    2009-12-01

    As dental schools incorporate training in evidence-based dentistry (EBD) into their curricula, students must learn how to critically evaluate systematic reviews and meta-analyses. It is important that dental education in the United States support the American Dental Association's position statement on EBD, which defines "best evidence" as data obtained from all study designs. Given that much evidence is missing when EBD is derived from Cochrane Systematic Reviews' randomized clinical trials, we propose the creation of a dental practice network of U.S. dental schools. We developed an electronic clinical dentistry research database for EBD using Epi-Info (available at www.cdc.gov/epiinfo/downloads.htm). As a free, public use software, Epi-Info provides the foundation for the development of clinical research databases that can increase the research capacity through multisite studies designed to generate outcomes data on the effectiveness of dental treatment. The creation of a dental practice network of dental schools with their large number of patients would expand the research capacity for EBD practice and advance the EBD science regarding the effectiveness of dental treatment. The next step is to link clinical dental researchers/educators at multiple dental schools through a collaborative clinical research network, so that the findings can be applied to the EBD component of problem-based learning curricula of dental education.

  14. Maintaining proper dental records.

    PubMed

    Leeuw, Wilhemina

    2014-01-01

    Referred to as Standard of Care, the legal duty of a dentist requires exercising the degree of skill and care that would be exhibited by other prudent dentists faced with the same patient-care situation. Primarily, the goal of keeping good dental records is to maintain continuity of care. Diligent and complete documentation and charting procedures are essential to fulfilling the Standard of Care. Secondly, because dental records are considered legal documents they help protect the interest of the dentist and/or the patient by establishing the details of the services rendered. Patients today are better educated and more assertive than ever before and dentists must be equipped to protect themselves against malpractice claims. Every record component must be handled as if it could be summoned to a court room and scrutinized by an attorney, judge or jury. Complete, accurate, objective and honest entries in a patient record are the only way to defend against any clinical and/or legal problems that might arise. Most medical and dental malpractice claims arise from an unfavorable interaction with the dentist and not from a poor treatment outcome. By implementing the suggestions mentioned in this course, dental health care professionals can minimize the legal risks associated with the delivery of dental care to promote greater understanding for patients of their rights and privileges to their complete record.

    2006-10-01

    During the last decades, people have tried to develop a better material for use in dental obturation materials. This new material should meet the following requirements: durability, wear resistance, biocompatibility and chemical adhesion to dentin enamel. Wear resistance is very important and it is related with the service life of dental replacements. We have obtained aesthetically promising novel nano composites that can be used as dental replacements. The main objective of this work is to study the scratch and wear resistance of these nano composites. To meet this goal, scratch tests are performed using a micro scratch tester machine (CSEM), where a diamond indenter is used to make the scratch and the penetration of this indenter is measured with high resolution (7nm). We will be looking at the penetration depth (Rp) and the residual (or healing) depth (Rh) to calculate the percent recovery. These measurements represent the scratch resistance of the material.

    Dental amalgam has served as an excellent and versatile restorative material for many years, despite periods of controversy. The authors review its history, summarize the evidence with regard to its performance and offer predictions for the future of this material. The PubMed database was used initially; the reference list for dental amalgam featured 8641 articles and 13 publications dealing with recent advances in dental amalgam. A forward search was undertaken on selected articles and using some author names. For the present, amalgam should remain the material of choice for economic direct restoration of posterior teeth. When esthetic concerns are paramount, tooth-colored materials, placed meticulously, can provide an acceptable alternative. All alternative restorative materials and procedures, however, have certain limitations. PMID:21217947

    Inflammatory periodontal disease is a major cause of loss of tooth-supporting structures. Novel approaches for regeneration of periodontal apparatus is an area of intensive research. Periodontal tissue engineering implies the use of appropriate regenerative cells, delivered through a suitable scaffold, and guided through signaling molecules. Dental pulp stem cells have been used in an increasing number of studies in dental tissue engineering. Those cells show mesenchymal (stromal) stem cell-like properties including self-renewal and multilineage differentiation potentials, aside from their relative accessibility and pleasant handling properties. The purpose of this article is to review the biological principles of periodontal tissue engineering, along with the challenges facing the development of a consistent and clinically relevant tissue regeneration platform. This article includes an updated review on dental pulp stem cells and their applications in periodontal regeneration, in combination with different scaffolds and growth factors. PMID:26620980

    2015-10-01

    Dental implants have increased in the last few decades thus increasing the number of complications. Since many of these complications are easily diagnosed on postsurgical images, it is important for radiologists to be familiar with them and to be able to recognize and diagnose them. Radiologists should also have a basic understanding of their treatment. In a pictorial fashion, this article will present the basic complications of dental implants which we have divided into three general categories: biomechanical overload, infection or inflammation, and other causes. Examples of implant fracture, loosening, infection, inflammation from subgingival cement, failure of bone and soft tissue preservation, injury to surround structures, and other complications will be discussed as well as their common imaging appearances and treatment. Lastly, we will review pertinent dental anatomy and important structures that are vital for radiologists to evaluate in postoperative oral cavity imaging.

    1983-01-01

    The National High-Altitude Photography Program (NHAP) is a multi-Federal agency activity to acquire uniform imagery for the establishment of a national high-altitude photographic data base. Federal agencies participating in NHAP have pooled their resources and consolidated photographic requirements in a systematic 6-year effort that will minimize duplication of photographic programs, reduce overall Federal expenditures for aerial photography, and provide imagery for a wide range of public and private users, The U.S. Geological Survey has the lead coordination role and shares, with the other participating agencies, the responsibility for funding the acquisition of photography. Since the inception of NHAP in 1980, black-and-white and color infrared stereoscopic imagery has been acquired for about 50% of the 3,000,000 square miles in the conterminous United States. An additional 40% of the 48-State area is under contract to provide aerial survey firms, and the sixth and final contract to achieve complete once-over coverage will be awarded early in 1985. Extensive use has been made of the newly established data base for mapping, landform studies, land use planning, natural resource inventory, evaluation and management, engineering, and education. In anticipation of the completion of once-over coverage, the participating agencies have begun studies to define the requirements for a maintenance program which would provide cyclic coverage of the conterminous United States and imagery for specific agency needs. Although continued funding at the same level is not assured, under consideration are requirements for new cameras, films, and other remote sensors, photographic parameters, and extension of program coverage to Alaska, Hawaii, and outlying areas. In addition, new applications of the data base to prepare cartographic map and data products are being investigated. It is becoming increasingly clear that some major decision needs to be made soon if a NHAP II is to begin in

    Athabasca University (AU), Athabasca University Geophysical and Geo-Space Observatories (AUGO / AUGSO), the Rotary Club of Athabasca and Science Outreach Athabasca has designed a three day science workshop entitled Photography and the Night Sky. This pilot workshop, aimed primarily at high-school aged students, serves as an introduction to observational astronomy as seen in the western Canadian night sky using digital astrophotography without the use of a telescope or tracking mount. Participants learn the layout of the night sky by proficiently photographing it using digital single lens reflex camera (DSLR) kits including telephoto and wide-angle lenses, tripod and cable release. The kits are assembled with entry-level consumer-grade camera gear as to be affordable by the participants, if they so desire to purchase their own equipment after the workshop. Basic digital photo editing is covered using free photo editing software (IrfanView). Students are given an overview of observational astronomy using interactive planetarium software (Stellarium) before heading outdoors to shoot the night sky. Photography is conducted at AU's auroral observatories, both of which possess dark open sky that is ideal for night sky viewing. If space weather conditions are favorable, there are opportunities to photograph the aurora borealis, then compare results with imagery generated by the all-sky auroral imagers located at the Geo-Space observatory. The aim of this program is to develop awareness to the science and beauty of the night sky, while promoting photography as a rewarding, lifelong hobby. Moreover, emphasis is placed on western Canada's unique subauroral location that makes aurora watching highly accessible and rewarding in 2013, the maximum of the current solar cycle.

  4. Practice of near-infrared photography of snowpits

    Schneebeli, M.

    2008-12-01

    Documentation and quantification of snow pits using near-infrared sensitive photography is a cheap and efficient technique (Matzl and Schneebeli, 2006). However, the quantitative processing of images from conventional digital cameras is not without pitfalls. The camera must be calibrated for intensity variation caused by the optic, which must done under homogenous illumination. In the field, a simple way was found to setup diffuse illumination, to prepare the pit, to position the calibration targets and to take the flat field reference image. The processing of the raw image to determine the absolute reflectivity requires several steps. First, the green channel of the raw image is extracted and interpolated. The green channel of most digital CCD has the highest number of pixels. Because the red-green-blue filters on the chip filter near- infrared red differently, a single color channel image is less noisy than a composite image. This raw image is then normalized by the optical correction image, and subsequently corrected for illumination heterogeneity by the field flat field image. This image can now be referenced to absolute reflectivity using the calibration targets. The calibrated image is used to segment quantitatively for optical grain diameter and specific surface area. A more qualitative interpretation of the snow stratigraphy, using image classification algorithms, is also possible. The equipment developed for near-infrared photography is transportable in a backpack and is used in alpine terrain. Images from different field campaigns in the Alps show the wide range of features, which are not easily documented using traditional stratigraphy.

    Airborne color-infrared photography (CIR) (1:12,000 scale) was used to map localized occurrences of the widespread and aggressive Chinese tallow (Sapium sebiferum), an invasive species. Photography was collected during senescence when Chinese tallow's bright red leaves presented a high spectral contrast within the native bottomland hardwood and upland forests and marsh land-cover types. Mapped occurrences were conservative because not all senescing tallow leaves are bright red simultaneously. To simulate low spectral but high spatial resolution satellite/airborne image and digital video data, the CIR photography was transformed into raster images at spatial resolutions approximating 0.5 in and 1.0 m. The image data were then spectrally classified for the occurrence of bright red leaves associated with senescing Chinese tallow. Classification accuracies were greater than 95 percent at both spatial resolutions. There was no significant difference in either forest in the detection of tallow or inclusion of non-tallow trees associated with the two spatial resolutions. In marshes, slightly more tallow occurrences were mapped with the lower spatial resolution, but there were also more misclassifications of native land covers as tallow. Combining all land covers, there was no difference at detecting tallow occurrences (equal omission errors) between the two resolutions, but the higher spatial resolution was associated with less inclusion of non-tallow land covers as tallow (lower commission error). Overall, these results confirm that high spatial (???1 m) but low spectral resolution remote sensing data can be used for mapping Chinese tallow trees in dominant environments found in coastal and adjacent upland landscapes.

    The service works in high-speed photography carried out by the Department of Precision Instruments, Tianjin University are described in this paper. A compensation type high-speed camera was used in these works. The photographic methods adopted and better results achieved in the studies of several technical fields, such as velocity field of flow of overflow surface of high dam, combustion process of internal combustion engine, metal cutting, electrical are welding, experiment of piling of steel tube piles for supporting the marine platforms and characteristics of motion of wrist watch escape mechanism and so on are illustrated in more detail. As the extension of human visual organs and for increasing the abi-lities of observing and studying the high-speed processes, high-speed photography plays a very important role. In order to promote the application and development on high-speed photography, we have carried out the consultative and service works inside and outside Tianjin Uni-versity. The Pentazet 35 compensation type high-speed camera, made in East Germany, was used to record the high-speed events in various kinds of technical investigations and necessary results have been ob-tained. 1. Measurement of flow velocity on the overflow surface of high dam. In the design of a key water control project with high head, it is extremely necessary to determinate various characteristics of flow velocity field on the overflow surface of high dam. Since the water flow on the surface of high overflow dam possesses the features of large flow velocity and shallow water depth, therefore it is difficult to use the conventional current meters such as pilot tube, miniature cur-rent meter or electrical measuring methods of non-electrical quantities for studying this problem. Adopting the high-speed photographic method to study analogously the characteristics of flow velocity field on the overflow surface of high dam is a kind of new measuring method. People

    1984-01-01

    A continuing problem in high-speed motion picture photography is adequate lighting and the associated temperature rise. Large temperature rises can damage subject matter and make recording of the desired images impossible. The problem is more severe in macrophotography because of bellows extension and the necessary increase in light. This report covers one approach to reducing the initial temperature rise: the use of filters and heat-absorbing materials. The accompanying figures provide the starting point for selecting distance as a function of light intensity and determining the associated temperature rise. Using these figures will allow the photographer greater freedom in meeting different photographic situations.

  8. Long-term change detection from historical photography

    Yoon, T.; Schenk, T.

    2006-12-01

    There is an increasing awareness in the science community about the potential of utilizing old photography and derived products together with new data for change detection and for extending the timeline as far back as possible. For example recent observations have revealed dramatic changes in the behavior of many ice streams and outlet glaciers in Greenland and Antarctica, ranging from complete shutdown of ice streams to manifold increases in velocity. Most observations are typically from the comparatively short time period since the beginning of the civilian satellite imagery (1980s), with most quantitative measurements starting only 10-15 years ago. To evaluate whether ongoing observed changes are climatically significant, changes must be determined over longer time frames. Earlier terrestrial and aerial photography and maps indeed exist and the objective of the project to disseminate these historical data and to develop techniques and tools for combining (fusing) old and new data in order to compile long-term time series of changes in the polar regions, for example in ice extent, velocity and surface elevations. The presentation focuses on new methodologies and interdisciplinary approaches that greatly facilitate the use of old photography for quantitative studies in the polar regions. An absolute prerequisite for the successful use of old photography is a rigorous registration, either with other sensory input data or with respect to 3D reference systems. Recent advances in digital photogrammetry allow registration with linear features, such as lines, curves and free-form lines without the need for identifying identical points. The concept of sensor invariant features was developed to register such disparate data sets as aerial imagery and 3D laser point clouds, originating from satellite laser altimetry or airborne laser scanning systems. Examples illustrating these concepts are shown from the Transantarctic Mountains, including the registration of aerial

    Summary Ocular fundus examination is a fundamental component of the neurologic examination. Finding papilledema in headache patients or retinal arterial emboli in stroke patients can be extremely useful. Although examination of the ocular fundus with a direct ophthalmoscope is an important skill for all neurologists, it is rarely and unreliably performed. Nonmydriatic ocular fundus photography, which allows direct visualization of high-quality photographs of the ocular fundus, has been recently proposed for screening neurologic patients in urgent care settings such as emergency departments. This new technology has many potential applications in neurology, including e-transmission of images for remote interpretation. PMID:24353924

    The underutilized practice of photographing anatomic pathology specimens from surgical pathology and autopsies is an invaluable benefit to patients, clinicians, pathologists, and students. Photographic documentation of clinical specimens is essential for the effective practice of pathology. When considering what specimens to photograph, all grossly evident pathology, absent yet expected pathologic features, and gross-only specimens should be thoroughly documented. Specimen preparation prior to photography includes proper lighting and background, wiping surfaces of blood, removing material such as tubes or bandages, orienting the specimen in a logical fashion, framing the specimen to fill the screen, positioning of probes, and using the right-sized scale.

    2007-05-10

    The use of different pupils for storing each speckled image in speckle photography is employed to determine multiple in-plane rotations. The method consists of recording a four-exposure specklegram where the rotations are done between exposures. This specklegram is then optically processed in a whole field approach rendering isothetic fringes, which give detailed information about the multiple rotations. It is experimentally demonstrated that the proposed arrangement permits the depiction of six isothetics in order to measure either six different angles or three nonparallel components for two local general in-plane displacements.

    By all outward signs, the dental profession is prospering. However, signs of a looming crisis in dental education threaten the future effectiveness of the profession. Transforming dental education through the application of principles espoused by the ADEA Commission on Change and Innovation in Dental Education (CCI) is essential for securing the future of the profession. To meet the future oral health needs of the public, dental schools must retain their research mission and prepare students for evidence-based practice. To accomplish this, both the curricular content and the environment and approach to dental education must change. Besides the knowledge and abilities needed to care for a more diverse and aging population, future practitioners must possess tools needed to thrive in the world of small business and have the ethical foundation to conduct themselves as responsible professionals. Ensuring the future of the profession is a leadership challenge to be shared by both dental educators and practitioners.

    2015-10-01

    Red-free light allows better detection of vascular lesions as this wavelength is absorbed by hemoglobin; however, the current gold standard for the detection and grading of diabetic retinopathy remains 7-field color fundus photography. The goal of this study was to compare the ability of 7-field fundus photography using red-free light to detect retinopathy lesions with corresponding images captured using standard 7-field color photography. Non-stereoscopic standard 7-field 30° digital color fundus photography and 7-field 30° digital red-free fundus photography were performed in 200 eyes of 103 patients with various grades of diabetic retinopathy ranging from mild to moderate non-proliferative diabetic retinopathy to proliferative diabetic retinopathy. The color images (n = 1,400) were studied with corresponding red-free images (n = 1,400) by one retina consultant (PV) and two senior residents training in retina. The various retinal lesions [microaneurysms, hemorrhages, hard exudates, soft exudates, intra-retinal microvascular anomalies (IRMA), neovascularization of the retina elsewhere (NVE), and neovascularization of the disc (NVD)] detected by all three observers in each of the photographs were noted followed by determination of agreement scores using κ values (range 0-1). Kappa coefficient was categorized as poor (≤0), slight (0.01-0.20), fair (0.2 -0.40), moderate (0.41-0.60), substantial (0.61-0.80), and almost perfect (0.81-1). The number of lesions detected by red-free images alone was higher for all observers and all abnormalities except hard exudates. Detection of IRMA was especially higher for all observers with red-free images. Between image pairs, there was substantial agreement for detection of hard exudates (average κ = 0.62, range 0.60-0.65) and moderate agreement for detection of hemorrhages (average κ = 0.52, range 0.45-0.58), soft exudates (average κ = 0.51, range 0.42-0.61), NVE (average κ = 0.47, range 0.39-0.53), and NVD

  2. Drugs that promote dental caries.

    PubMed

    2015-02-01

    Dental caries result from erosion of tooth enamel or cementum by acidic substances produced by bacteria found in dental plaque. Caries can lead to pulp necrosis and tooth loss. Risk factors include certain dietary habits, poor oral hygiene, and dry mouth. Diabetes and Sjogren's syndrome can also promote dental caries. Psychotropic substances such as cocaine, methamphetamine, heroin and cannabis can promote dental caries. Many medicinal drugs facilitate the formation of dental caries, through various mechanisms; they include formulations with a high sugar content; drugs that cause dry mouth (especially antimuscarinics); drugs that lower the buccal pH (inhaled powders, etc.); and drugs that cause demineralisation (tetracyclines, etc.). In practice, patients (and parents) should be informed that some drugs can increase the risk of dental caries. They should be encouraged to adapt and reinforce dental hygiene, and advised to visit a dentist regularly. PMID:25802916

  4. Review of Spaceflight Dental Emergencies

    NASA Technical Reports Server (NTRS)

    Menon, Anil

    2012-01-01

    All exploration class missions--extending beyond earth's orbit--differ from existing orbital missions by being of longer duration and often not having a means of evacuation. If an exploration mission extends beyond a year, then there will be a greater lapse since the crewmembers last terrestrial dental exams, which routinely occur each year. This increased time since professional dental care could increase the chance of a dental emergency such as intractable pain, dental decay requiring a temporary filling, crown replacement, exposed pulp, abscess, tooth avulsion, or toothache. Additionally, any dental emergency will have to be treated in-flight with available resources and personnel who may not have extensive training in dental care. Thus, dental emergencies are an important risk to assess in preparation for exploration missions.

    Procedures were developed and tested for using KA-80A optical bar camera panoramic photography for timber typing forest land and classifying nonforest land. The study area was the south half of the Lake Tahoe Basin Management Unit. Final products from this study include four timber type map overlays on 1:24,000 orthophoto maps. The following conclusions can be drawn from this study: (1) established conventional timber typing procedures can be used on panoramic photography if the necessary equipment is available, (2) The classification and consistency results warrant further study in using panoramic photography for timber typing; and (3) timber type mapping can be done as fast or faster with panoramic photography than with resource photography while maintaining comparable accuracy.

  7. FATIGUE OF DENTAL CERAMICS

    PubMed Central

    Zhang, Yu; Sailer, Irena; Lawn, Brian R

    2013-01-01

    Objectives Clinical data on survival rates reveal that all-ceramic dental prostheses are susceptible to fracture from repetitive occlusal loading. The objective of this review is to examine the underlying mechanisms of fatigue in current and future dental ceramics. Data/sources The nature of various fatigue modes is elucidated using fracture test data on ceramic layer specimens from the dental and biomechanics literature. Conclusions Failure modes can change over a lifetime, depending on restoration geometry, loading conditions and material properties. Modes that operate in single-cycle loading may be dominated by alternative modes in multi-cycle loading. While post-mortem examination of failed prostheses can determine the sources of certain fractures, the evolution of these fractures en route to failure remains poorly understood. Whereas it is commonly held that loss of load-bearing capacity of dental ceramics in repetitive loading is attributable to chemically-assisted 'slow crack growth' in the presence of water, we demonstrate the existence of more deleterious fatigue mechanisms, mechanical rather than chemical in nature. Neglecting to account for mechanical fatigue can lead to gross overestimates in predicted survival rates. Clinical significance Strategies for prolonging the clinical lifetimes of ceramic restorations are proposed based on a crack-containment philosophy. PMID:24135295

  12. Ethics of dental health screening.

    PubMed

    Janakiram, Chandrashekar; Taha, Farheen

    2016-01-01

    Screening is the detection of disease at a point in its natural history when it is not yet symptomatic. In the natural history of dental caries, for example, the incipient lesions are at a reversible stage, which is a pre-symptomatic or an unrecognised symptomatic disease. Ideally, this is the stage during which screening should identify the risk of dental caries; however, presently, the so-called dental screening employed identifies the clinical cavitation of the tooth, which is very obvious to the individual. The individual already knows that he/she has dental caries and needs treatment, which the screening personnel (dental doctor) explains again during the screening procedure. Is it ethical to call such an event screening? The mushrooming of dental teaching hospitals has promoted regular screening of dental diseases among the communities and schoolchildren through their community dentistry-related activities. More often, it is a dental "check-up" that is carried out on the pretext of screening for dental diseases. Though the basic intention of this activity is to promote awareness of dental diseases and promote good health, there is also a hidden agenda to it. An artificial demand for dental care is created that is easily capitalised on by the dental teaching institutions to enhance its clinical activity. Dental screening is doing more harm than good as patients are made aware of the diseases for which they may not be able to afford treatment. This narrative review gives an account of the scientific evidence on screening for oral diseases, the current practices in screening and the ethical dilemmas of dental screening programmes.

  13. Computational photography with plenoptic camera and light field capture: tutorial.

    PubMed

    Lam, Edmund Y

    2015-11-01

    Photography is a cornerstone of imaging. Ever since cameras became consumer products more than a century ago, we have witnessed great technological progress in optics and recording mediums, with digital sensors replacing photographic films in most instances. The latest revolution is computational photography, which seeks to make image reconstruction computation an integral part of the image formation process; in this way, there can be new capabilities or better performance in the overall imaging system. A leading effort in this area is called the plenoptic camera, which aims at capturing the light field of an object; proper reconstruction algorithms can then adjust the focus after the image capture. In this tutorial paper, we first illustrate the concept of plenoptic function and light field from the perspective of geometric optics. This is followed by a discussion on early attempts and recent advances in the construction of the plenoptic camera. We will then describe the imaging model and computational algorithms that can reconstruct images at different focus points, using mathematical tools from ray optics and Fourier optics. Last, but not least, we will consider the trade-off in spatial resolution and highlight some research work to increase the spatial resolution of the resulting images. PMID:26560916

    2014-04-01

    Accurate assessment of acne severity is essential for determining the appropriate treatment required. This paper reviews photographic methods for such assessment. Literature included met the following criteria: proposed photographic standards to assess acne, evaluated such standards, or offered photographic methods to improve visualization and assessment. Validity was evaluated by comparing given photographic grading methods to other methods, such as lesion counting. Many photographic standards were shown to be objective, time-efficient, and have intra-grader and inter-grader consistency. Photography also documents progress for retrospective verification. Drawbacks include not allowing determination of depth, minimization of small lesions and erythema, and difficulty in maintaining consistent settings. Fluorescence and polarized photography improve visualization beyond clinical observation alone. Advances such as computer alignment, imaging segmentation, and three-dimensional analysis methods track lesions and measure objective characteristics. The combined experience summarized here strongly promotes the use of a photographic standard in assessing acne severity. Cook's method can also be used to train and qualify graders. Photographic advancements improve accuracy of assessment by solving problems with consistent settings and depth visualization. Further advancements can improve image analysis through analysis of objective attributes.

    Launched on July 26, 2005 from the Kennedy Space Center in Florida, STS-114 was classified as Logistics Flight 1. Among the Station-related activities of the mission were the delivery of new supplies and the replacement of one of the orbital outpost's Control Moment Gyroscopes (CMGs). STS-114 also carried the Raffaello Multi-Purpose Logistics Module and the External Stowage Platform-2. A major focus of the mission was the testing and evaluation of new Space Shuttle flight safety, which included new inspection and repair techniques. Upon its approach to the International Space Station (ISS), the Space Shuttle Discovery underwent a photography session in order to assess any damages that may have occurred during its launch and/or journey through Space. Discovery was over Switzerland, about 600 feet from the ISS, when Cosmonaut Sergei K. Kriklev, Expedition 11 Commander, and John L. Phillips, NASA Space Station officer and flight engineer photographed the spacecraft as it performed a back flip to allow photography of its heat shield. Astronaut Eileen M. Collins, STS-114 Commander, guided the shuttle through the flip. The photographs were analyzed by engineers on the ground to evaluate the condition of Discovery's heat shield. The crew safely returned to Earth on August 9, 2005. The mission historically marked the Return to Flight after nearly a two and one half year delay in flight after the Space Shuttle Columbia tragedy in February 2003.

    1988-01-01

    This study demonstrates the feasibility of using low-altitude aerial photography to inventory submersed macrophytes in the connecting channels of the Great Lakes. For this purpose, we obtained aerial color transparencies and collateral ground truth information about submersed vegetation at 160 stations within four study sites in the St. Clair and Detroit rivers, September 17 to October 4, 1984. Photographs were interpreted by five test subjects to determine with what accuracy they could detect beds of submersed macrophytes, and the precision of delineating the extent of such vegetation beds. The interpreters correctly determined the presence or absence of vegetation 80% of the time (range 73-86%). Differences between individuals were statistically significant. Determination of the presence or absence of macrophytes depended partly on their relative abundance and water clarity. Analysis of one photograph from each of the four study sites revealed that photointerpreters delineated between 35 and 75 ha of river bottom covered by vegetation. This wide range indicates that individuals should be tested to assess their relative capability and be trained before they are employed to delineate plant beds in large-scale inventories. Within limits, low-altitude aerial photography, combined with collateral ground truth information, can be used to determine the presence or absence and delineate the extent of submersed macrophytes in connecting channels of the Great Lakes.

    A committee of trained classroom teachers, backed by a volunteer team of technical experts and academic advisors has developed a program for earth science based on photographs obtained from low earth orbit. In selecting targeting objectives, immediate note was made of the fact nearly one generation (20 years) has passed since the United States' ambitious SKYLAB program was conducted. A critical part of those missions was the acquisition of earth photography using a six camera, multi-spectral camera system. This objective was systematically furthered through the term of three separate crew visits to the Space Station. Not merely an exercise in randomly photographing the Earth below, the purpose of the Earth Resource Experiment Package (EREP) was to determine what kind, and how much, photographic data could be acquired of the broad variety of Earth features witnessed on the mission's ground track. The collection of 35,000 photos produced by EREP represents the most complete coverage of Earth. However, it remains under used.

    2010-01-01

    This chapter explores iconography in neurology from the birth of photography up to the early medical applications of cinematography before 1914. The important visual part of neurological diagnosis explains why these techniques were adopted very early by neurologists. Duchenne published the first medical book illustrated with photographs of patients. The first and most famous photographic laboratory was created in Charcot's department, at the Salpêtrière in Paris, under the direction of Albert Londe. Londe published the first book dedicated to medical photography. The physiologist Marey and the photographer Muybridge, in association with neurologists, played key roles in the development of chronophotography and cinematography. Germany was the first country to welcome cinematography in a neurology department. Independently, neurologists began to film patients in other countries in Europe and in America. In 1905, Arthur Van Gehuchten (1861-1914), Belgian anatomist and neurologist, began systematically to film neurologic patients, with the intention of building up a complete neurological iconographic collection. This collection has survived and has been restored in the laboratory of the Royal Belgian Film Archive where the films are now safely stored in their vaults.

    Background: A sensitive method is required to detect retinal hamartomas in patients with tuberous sclerosis complex (TSC). The aim of the present study was to compare the color fundus photography, infrared imaging (IFG), and optical coherence tomography (OCT) in the detection rate of retinal hamartoma in patients with TSC. Methods: This study included 11 patients (22 eyes) with TSC, who underwent color fundus photography, IFG, and spectral-domain OCT to detect retinal hamartomas. TSC1 and TSC2 mutations were tested in eight patients. Results: The mean age of the 11 patients was 8.0 ± 2.1 years. The mean spherical equivalent was −0.55 ± 1.42 D by autorefraction with cycloplegia. In 11 patients (22 eyes), OCT, infrared fundus photography, and color fundus photography revealed 26, 18, and 9 hamartomas, respectively. The predominant hamartoma was type I (55.6%). All the hamartomas that detected by color fundus photography or IFG can be detected by OCT. Conclusion: Among the methods of color fundus photography, IFG, and OCT, the OCT has higher detection rate for retinal hamartoma in TSC patients; therefore, OCT might be promising for the clinical diagnosis of TSC.

  15. Dental extractions using improvised equipment.

    PubMed

    Iserson, Kenneth V

    2013-12-01

    Extracting a tooth is the final treatment for multiple dental problems. Persons who are not dentists, however, have little experience with tooth extractions. When a remote setting makes it impossible to send a patient for optimal dental treatment, the clinician may need to extract teeth, sometimes using improvised equipment. The following cases of two patients with three carious, painful molars describe such a situation. The non-dental clinicians had to improvise not only appropriate dental tools, but also personal protective equipment, a functional suction machine, medications for a dental block, a dental chair, and dental consent forms and follow-up instructions in the patients' language. In these cases, they also communicated with their patients through a translator. To prepare to do tooth extractions in remote settings, clinicians should learn and practice dental blocks and review extraction techniques before they deploy. If they must do an extraction, clinicians should use the closest approximation available to the appropriate dental tools. When done correctly, a dental extraction can take some time and should not be rushed. PMID:24076092

  16. Dental care demand among children with dental insurance.

    PubMed Central

    Grembowski, D; Conrad, D A; Milgrom, P

    1987-01-01

    As the number of families with dental insurance and expenditures for dental care has increased over the past two decades, so has interest in determining cost-sharing effects on dental demand among insureds. Using a representative sample of Pennsylvania Blue Shield children insureds during 1980, we estimate cost-sharing effects on dental demand for basic (diagnostic, preventive, restorative, endodontic, and extraction services) and orthodontic care. Results indicate that cost-sharing has little influence on the probability of using any dental services and basic expenditures. However, the probability of using orthodontic services decreases 2.1 percent when the proportion of orthodontic expenditures paid by the parent increases 10 percent. By reducing the cost of care, cost-sharing reduces social class differences in dental demand common in unisured populations, likely producing public oral health benefits. PMID:2952622

  17. Dental therapists in general dental practices: an economic evaluation.

    2012-08-01

    Dental access disparities are well documented and have been recognized as a national problem. Their major cause is the lack of reasonable Medicaid reimbursement rates for the underserved. Specifically, Medicaid reimbursement rates for children average 40 percent below market rates. In addition, most state Medicaid programs do not cover adults. To address these issues, advocates of better oral health for the underserved are considering support for a new allied provider--a dental therapist--capable of providing services at a lower cost per service and in low-income and rural areas. Using a standard economic analysis, this study estimated the potential cost, price, utilization, and dentist's income effects of dental therapists employed in general dental practices. The analysis is based on national general dental practice data and the broadest scope of responsibility for dental therapists that their advocates have advanced, including the ability to provide restorations and extractions to adults and children, training for three years, and minimum supervision. Assuming dental therapists provide restorative, extraction, and pulpal services to patients of all ages and dental hygienists continue to deliver all hygiene services, the mean reduction in a general practice costs ranges between 1.57 and 2.36 percent. For dental therapists treating children only, the range is 0.31 to 0.47 percent. The effects on price and utilization are even smaller. In addition, the effects on most dentists' gross income, hours of work, and net income are negative. The estimated economic impact of dental therapists in the United States on private dental practice is very limited; therefore, the demand for dental therapists by private practices also would probably be very limited.

    Minimal dimensional changes in free standing dental implants when incinerated in a kiln to a temperature of 1125°C have been reported previously. However, in the same study colour changes were observed between commercially pure titanium and titanium alloy type of implants, with speculation that this change may be a useful distinguishing tool in cases requiring forensic identification. The present study was instigated to determine what changes occur following cremation to bone-supported dental implants placed within mandibles of sheep. A selection of dental implants was photographed and radiographed. They were then surgically placed in sheep mandibles and the entire sheep heads cremated in a commercial cremator. There was detachment of the dental implants from the mandible, which could have implications for scene recovery. Following retrieval and re-irradiating of the implants, image subtraction evaluation of the radiographs was recorded using Adobe(®) Photoshop.(®) As with the previous study there was slight oxidation of the implant surfaces leading to minor alteration of the images. There was, however, no gold crust colour change in the commercially pure titanium. Photography within the retrieved implants revealed the batch number within the Straumann™ implant was still visible, which could significantly add weight to the identification of deceased persons.

  20. Volga shallow offing dynamics investigation based on space photography

    NASA Astrophysics Data System (ADS)

    Kovalev, E. E.

    Volga mouth region is investigated much better, than sea mouths of other river in Russia. In spite of the fact, not enough attention was devoted to Volga shallow offing. Volga shallow offing covers area about 9,3 ths. sq. km and has great significance for Caspian sea fish industry, because environmental conditions of this region and neighboring shallows of Northern Caspian Sea are determinative for passage, spawning and young fish growth of valuable sorts of fish. Insufficient investigation of Volga shallow offing is caused as by difficulty of access to this region through small depths (1 - 2 m) and intensive vegetation, so by data deficiency. Data deficiency notably intensified during recent 10 - 15 years, when significant reduction of hydro-meteorological investigations in Volga mouth area occurred. Gradual accumulation of on-site data, development of new technologies of map material analysis and space photography data processing allows to expect new scientific and application results. The purpose of our investigation concludes in determination of space-time mechanism of hydro-meteorological processes in Volga shallow offing based on space photography materials. Main results of our investigation can be summarized in following basic statements: (1) The most efficient method of Volga shallow offing investigation appears to be combined application of space photography data and on-site materials. (2) Electronic atlas of Volga shallow offing photomaps for the period of 1975 to 1997 yrs. is created. (3) Maps of above-water flora of Volga shallow offing for 1975 and 1997 yrs are created. (4) Electronic atlas of streams in Volga shallow offing for the period of 1975 to 1997 yrs. is created. On basis of it four maps of drain streams at Volga shallow offing are created. (5) Landscape zoning of Volga shallow offing is made and most active and passive regions are determined depending on drain streams and water vegetation. (6) It is shown, that development of Volga shallow

  1. Predicting dental avoidance among dentally fearful Australian adults.

    Armfield, Jason M

    2013-06-01

    Dental fear is related to poorer oral health outcomes, and this might be explained by the less frequent dental visiting of many fearful people. The objectives of this study were to investigate differences between dentally fearful people who regularly attend the dentist and fearful people who infrequently visit the dentist. A random sample of 1,082 Australians ≥ 15 yr of age completed a mailed questionnaire (response rate = 71.6%), and 191 dentate, high-fear adults (≥ 18 yr of age) were selected for further analysis. Dental avoidance was recorded if a person was currently avoiding or delaying dental care and if he/she had not been to a dentist in the previous 2 yr. Among the selected dentally fearful adults, dental avoidance was predicted by smoking status, toothbrushing frequency, coping strategy use, perceptions of dental visits as uncontrollable and unpredictable, and by anxiety relating to numbness, not knowing what the dentist is going to do, and cost. In a multivariate logistic regression model, smoking, toothbrushing, coping, and anxiety about numbness and cost remained as statistically significant predictors, with the model accounting for 30% of the variance. While several variables were associated with dental avoidance among fearful adults, the nature and causal directions of these associations remain to be established.

    Orofacial injuries and diseases occur in athletes, and they may not always have access to dentists. Therefore team physicians should be aware of the common injuries and initial management. Treatment of dental injuries will depend on whether the teeth are primary or permanent. The most common type of fracture is crown fracture, but there are other dental injuries that can lead to future complications if not treated promptly and monitored closely. Tooth avulsions need to be handled properly, and athletes should see a dentist as soon as possible. Despite the urgency of some injuries, other orofacial injuries or diseases, such as lacerations and caries, should not be overlooked. Proper education and use of mouth guards can assist athletes in reducing their risk of orofacial injuries. PMID:25574879

  3. Let's go outside: using photography to explore values and culture in mental health nursing.

    2015-06-01

    Creative and imaginative approaches to mental healthcare education are known to help students explore emotions, empathy and others' experiences, as well as address ambivalence and ambiguity. Very few studies in mental health nursing education specifically utilise photography as a participatory pedagogic tool, with even fewer utilising photography to explore understandings of culture, values and diversity. Photography makes visible complex, collaborative forms of learning and previously unidentified, unarticulated ideas about culture and values. Photography as a critical pedagogic method helps develop critical, politicized understandings of culture and values. Increasing culturally diverse populations means complex and conflicting values have become a common feature in mental health nursing. In education the need to critically examine such topics necessitates creative and engaging pedagogy, and visual methods are readily acknowledged as such. Yet while many studies advocate and demonstrate the value of art-based methods in student learning, very few studies in mental health nursing specifically utilize photography as a participatory pedagogic tool, and fewer still use photography to explore understandings of culture, values and diversity. In this paper, we discuss a qualitative study where mental health nursing students used photography to create images in order to explore their own and often dominant culture and attendant values. Findings suggest that photography makes visible situated, relational and collaborative learning, and surfaces previously unidentified, unarticulated ideas about culture and values. These practices mimic important processes central to mental health nursing practice and contemporaneous understandings of diverse cultures. We argue that photography provides an important resource with which to unearth subjugated knowledge, promote critical understandings of culture and values, and thereby help address inequalities in mental health care.

  4. Application of multispectral color photography to flame flow visualization

    1979-01-01

    For flames of short duration and low intensity of radiation a spectroscopical flame diagnostics is difficult. In order to find some other means of extracting information about the flame structure from its radiation, the feasibility of using multispectral color photography was successfully evaluated. Since the flame photographs are close-ups, there is a considerable parallax between the single images, when several cameras are used, and additive color viewing is not possible. Each image must be analyzed individually, it is advisable to use color film in all cameras. One can either use color films of different spectral sensitivities or color films of the same type with different color filters. Sharp cutting filters are recommended.

  5. Absorbing New Subjects: Holography as an Analog of Photography

    Johnston, Sean F.

    2006-05-01

    I discuss the early history of holography and explore how perceptions, applications, and forecasts of the subject were shaped by prior experience. I focus on the work of Dennis Gabor (1900 1979) in England,Yury N. Denisyuk (b. 1924) in the Soviet Union, and Emmett N. Leith (1927 2005) and Juris Upatnieks (b. 1936) in the United States. I show that the evolution of holography was simultaneously promoted and constrained by its identification as an analog of photography, an association that influenced its assessment by successive audiences of practitioners, entrepreneurs, and consumers. One consequence is that holography can be seen as an example of a modern technical subject that has been shaped by cultural influences more powerfully than generally appreciated. Conversely, the understanding of this new science and technology in terms of an older one helps to explain why the cultural effects of holography have been more muted than anticipated by forecasters between the 1960s and 1990s.

    The National High-Altitude Photography Program (NHAP) is a multi-Federal agency activity to acquire uniform imagery for the establishment of a national high-altitude photographic data base. Since the inception of NHAP in 1980, black-and-white and color infrared stereoscopic imagery has been acquired for about 50% of the 3,000,000 square miles in the conterminous United States. An additional 40% of the 48-State area is under contract to private aerial survey firms, and the sixth and final contract to achieve complete once-over coverage will be awarded early in 1985. Extensive use has been made of the newly established data base. The participating agencies have begun studies to define the requirements for a maintenance program which would provide cyclic coverage of the conterminous United States and imagery for specific agency needs.

    Community arts and cultural development is a process that builds on and responds to the aspirations and needs of communities through creative means. It is participatory and inclusive, and uses multiple modes of representation to produce local knowledge. 'Voices' used photography and photo elicitation as the medium for exploring and expressing sense of place among Aboriginal and non-Indigenous children, young people and adults in four rural towns. An analysis of data generated by the project shows the diverse images that people chose to capture and the different meanings they afforded to their pictures. These meanings reflected individual and collective constructions of place, based on positive experiences and emotions tied to the natural environment and features of the built environment. We discuss community arts and cultural development practice with reference to creative visual methodologies and suggest that it is an approach that can contribute to community psychology's empowerment agenda.

    Digital terrain models are becoming increasingly available and are readily generated at a whole range of scales. However, the lack of realistic colour and tone in images of terrains remains a problem. Realistic colour and tone are very desirable attributes because they contribute significantly to a powerful visualization of landscapes, both for scientists (Kam's ref) and for the general public. But these attributes are generally still unavailable because few sensors, air- or space-borne, provide true colour, and even fewer do so at a realistic cost. The exception is the growing and accessible archive of US Space Shuttle photography which provides a wealth of potential data suited for more realistic visualization of landscapes.

    1969-05-01

    The application of color-coded image separation to multiple-spark photography provides a simple method for recording shadow or schlieren photographs with arbitrary magnification, extremely high frame rate, short exposure time per frame, and no parallax. A color separation, multiple-spark camera is described which produces a sequence of three frames at 5 x magnification with a maximum frame rate of 10(6)/sec and an exposure time per frame of about 0.3 microsec. Standard 10.16-cm x 12.7-cm (4-in. x 5-in.) color film is used. This camera has been useful for observing liquid atomization processes and spray motion, since it enables direct measurement droplet size, location, velocity, and deceleration. PMID:20072366

    1985-11-01

    An automated image recognition system is described for speckle photography investigations in fluid dynamics. The system is employed for characterizing the pattern of interference fringes obtained using speckle interferometry. A rotating ground glass serves as a screen on which laser light passing through a specklegraph plate, the flow and a compensation plate (CP) is shone to produce a compensated Young's pattern. The image produced on the ground glass is photographed by a video camera whose signal is digitized and processed through a microcomputer using a 6502 CPU chip. The normalized correlation function of the intensity is calculated in two directions of the recorded pattern to obtain the wavelength and the light deflection angle. The system has a capability of one picture every two seconds. Sample data are provided for a free jet of CO2 issuing into air in both laminar and turbulent form.

I present five photographic and narrative case studies, spanning a range of trans partnerships in the UK, to demonstrate some of the complex ways in which bodies, genders, sexualities, and time intersect in trans intimacy. I argue that the photographs create an imaginative resource, both for the people depicted in the photographs and for those viewing the photographs, providing new possibilities for thinking about trans partnerships, expanding the ways in which trans intimate partnerships are imag(in)ed, and opening up new spaces of possibility for gender and sexual identities.

    2015-08-01

    Digital documentation is one of the most useful techniques to record the condition of cultural heritage. Recently, high-resolution images become increasingly useful because it is possible to show general views of mural paintings and also detailed mural conditions in a single image. As mural paintings are damaged by environmental stresses, it is necessary to record the details of painting condition on high-resolution base maps. Unfortunately, the cost of high-resolution photography and the difficulty of operating its instruments and software have commonly been an impediment for researchers and conservators. However, the recent development of graphic software makes its operation simpler and less expensive. In this paper, we suggest a new approach to make digital heritage inventories without special instruments, based on our recent our research project in Üzümlü church in Cappadocia, Turkey. This method enables us to achieve a high-resolution image database with low costs, short time, and limited human resources.

    1976-01-01

    Four-band multispectral photography obtained from an aerial platform at an altitude of about 10,000 feet has been utilized to measure near-surface turbidity at numerous sampling sites in the Ross Barnett Reservoir, Mississippi. Correlation of the photographs with turbidity measurements has been accomplished via an empirical mathematical model which depends upon visual color recognition when the composited photographs are examined on either an I squared S model 600 or a Spectral Data model 65 color-additive viewer. The mathematical model was developed utilizing least-squares, iterative, and standard statistical methods and includes a time-dependent term related to sun angle. This model is consistent with information obtained from two overflights of the target area - July 30, 1973 and October 30, 1973 - and now is being evaluated with regard to information obtained from a third overflight on November 8, 1974.

    1973-01-01

    Studies were conducted utilizing six different film and filter combinations to quantitatively detect chlorophyll and turbidity in six farm ponds. The low range of turbidity from 0-35 JTU correlated well with the density readings from the green band of normal color film and the high range above 35 JTU was found to correlate with density readings in the red band of color infrared film. The effect of many of the significant variables can be reduced by using standardized procedures in taking the photography. Attempts to detect chlorophyll were masked by the turbidity. The ponds which were highly turbid also had high chlorophyll concentrations; whereas, the ponds with low turbidity also had low chlorophyll concentrations. This prevented a direct correlation for this parameter. Several suggested approaches are cited for possible future investigations.

  17. Schlieren photography to study sound interaction with highly absorbing materials.

    PubMed

    Declercq, Nico F; Degrieck, Joris; Leroy, Oswald

    2005-06-01

    Strong absorption of sound is often caused by the conversion of sound energy into heat. When this happens, it is not possible to study the interaction of sound with the absorbing material by means of reflected sound characteristics, because there is no reflected sound. Detecting for example the distance that sound travels in a strongly absorbing material, can be done by heat detection systems. However, the presence of temperature detectors in such materials interferes with the sound field and is therefore not really suitable. Infrared measurements are a possible option. Another option is the use of Schlieren photography for simultaneous visualization of sound and heat. This technique is briefly outlined with a 3 MHz sound beam incident on a highly absorbing sponge.

    Based on the experience gained with the Condor2 long-range oblique photography (LOROP) camera, ELOP is expanding its airborne reconnaissance product line with the Condor TAC tactical photography system. The latter was designed for overflight imaging of extended areas from a fighter or special mission aircraft, at day and night. The Condor TAC is mounted in an aerodynamically shaped pod and can operate in wide envelope of flight altitude and speed. Besides the camera, the pod contains mission management and video processing unit (MVU), solid state recorder (SSR), wide-band data link (DL) for real-time imagery transmission, and two environmental control units (ECU). Complex multi-segment optical windows were successfully developed for the system. The camera system design is modular and highly flexible. Two independent imaging payload modules are mounted inside a gimbal system. Each of the modules is equipped with a strap-down IMU, and may carry a cluster of cameras or a single large camera with gross weight up to 35 kg. The payload modules are interchangeable, with an identical interface to the gimbal. The modularity and open architecture of the system facilitate its adaptation to various operational requirements, as well as allow easy and relatively non-expensive upgrades and configuration changes. In the current configuration, both EO and IR payload modules are equipped with a combination of longer focal length cameras for bi-directional panoramic scan at medium and high flight altitudes, and shorter focal length cameras for fixed wide angle coverage at low altitudes. All the camera types are equipped with standard format, off-the-shelf area detector arrays. Precise motion compensation is achieved by calibrated back-scan mirrors.

  1. Duchenne De Boulogne: a pioneer in neurology and medical photography.

    Guillaume-Benjamin-Amand Duchenne was born 200 years ago in Boulogne-sur-Mer (Pas-de-Calais, France). He studied medicine in Paris and became a physician in 1831. He practiced general medicine in his native town for about 11 years and then returned to Paris to initiate pioneering studies on electrical stimulation of muscles. Duchenne used electricity not only as a therapeutic agent, as it was commonly the case earlier in the 19th century, but chiefly as a physiological investigation tool to study the anatomy of the living body. Without formal appointment he visited hospital wards across Paris searching for rare cases of neuromuscular disorders. He built a portable electrical device that he used to functionally map all bodily muscles and to study their coordinating action in health and disease. He gave accurate descriptions of many neuromuscular disorders, including pseudohypertrophic muscular dystrophy to which his name is still attached (Duchenne muscular dystrophy). He also invented a needle system (Duchenne's histological harpoon) for percutaneous sampling of muscular tissue without anesthesia, a forerunner of today's biopsy. Duchenne summarized his work in two major treatises entitled De l'électrisation localisée (1855) and Physiologie des mouvements (1867). Duchenne's iconographic work stands at the crossroads of three major discoveries of the 19th century: electricity, physiology and photography. This is best exemplified by his investigation of the mechanisms of human physiognomy in which he used localized faradic stimulation to reproduce various forms of human facial expression. The album that complements his book on this issue is considered a true incunabulum of photography. Duchenne de Boulogne, a shy but hard-working, acute and ingenious observer, became one of most original clinicians of the 19th century. He died in Paris in 1875.

  2. Mapping Urban Ecosystem Services Using High Resolution Aerial Photography

    Ecosystem services (ES) are the many life-sustaining benefits we receive from nature: e.g., clean air and water, food and fiber, cultural-aesthetic-recreational benefits, pollination and flood control. The ES concept is emerging as a means of integrating complex environmental and economic information to support informed environmental decision making. The US EPA is developing a web-based National Atlas of Ecosystem Services, with a component for urban ecosystems. Currently, the only wall-to-wall, national scale land cover data suitable for this analysis is the National Land Cover Data (NLCD) at 30 m spatial resolution with 5 and 10 year updates. However, aerial photography is acquired at higher spatial resolution (0.5-3 m) and more frequently (1-5 years, typically) for most urban areas. Land cover was mapped in Raleigh, NC using freely available USDA National Agricultural Imagery Program (NAIP) with 1 m ground sample distance to test the suitability of aerial photography for urban ES analysis. Automated feature extraction techniques were used to extract five land cover classes, and an accuracy assessment was performed using standard techniques. Results will be presented that demonstrate applications to mapping ES in urban environments: greenways, corridors, fragmentation, habitat, impervious surfaces, dark and light pavement (urban heat island). Automated feature extraction results mapped over NAIP color aerial photograph. At this scale, we can look at land cover and related ecosystem services at the 2-10 m scale. Small features such as individual trees and sidewalks are visible and mappable. Classified aerial photo of Downtown Raleigh NC Red: impervious surface Dark Green: trees Light Green: grass Tan: soil

    Dental stem cells have recently become one of the widely researched areas in dentistry. Ever since the identification of stem cells from various dental tissues like deciduous teeth, dental papilla, periodontal ligament and third molars, storing them for future use for various clinical applications was being explored. Dental stem cells were harvested and isolated using various techniques by different investigators and laboratories. This article explains the technical aspects of preparing the patient, atraumatic and aseptic removal of the tooth and its safe transportation and preservation for future expansion. PMID:26538883

  4. Dental injuries during general anaesthesia.

    Chadwick, R G; Lindsay, S M

    1996-04-01

    Although most anaesthetic textbooks cite dental injury as a complication of endotracheal intubation few studies have examined the extent and nature of the problem. Such damage however, formed the basis for one-third of all confirmed or potential anaesthetic claims notified to the Medical Protection Society between 1977 and 1986. This article seeks to explore the extent of the problem, outline predisposing factors, summarise current prophylactic measures and make recommendations to reduce the overall incidence. Increased awareness of the problem, by both anaesthetists and dental surgeons, coupled with appropriate prophylactic measures may result in a reduced incidence of dental injury arising from general anaesthesia. Given the high incidence of dental damage we recommend that all patients undergoing a surgical operation under endotracheal intubation should have a pre-operative dental check wherever possible. Clearly, the first dental examination would be conducted by an anaesthetist familiar with the predisposing factors. Where he/she considers there to be a higher than average risk of dental damage occurring during intubation a more specialised examination should be conducted by a dental surgeon. It may, where appropriate, be possible for remedial dental treatment to be carried out and customised mouth guards to be constructed prior to the operation. Obviously such recommendations have certain financial implications and would have to be subject to controlled cost-benefit analysis before their widespread application. PMID:8935289

  5. Coinsurance effects on dental prices.

    For many Americans the cost of dental services represents a barrier to receiving regular dental care and maintaining proper oral health. The recent growth of the dental insurance industry, however, may partly offset this price barrier among insureds. Our purpose is to examine the relationship between coinsurance and dental prices for 16 dental services among a sample of Pennsylvania Blue Shield (PBS) adult insureds. The dependent price measure is the annual average gross price paid for 16 specific preventive, restorative, periodontic, endodontic, prosthodontic, and surgical dental services. Independent variables in the price model include the insured's age, education, coinsurance rates, time costs, market area, non-wage income, oral health status, area dentist-population ratio and usual source of care. Data sources are 1980 PBS claims and coinsurance rate data and a mail survey of sampled insureds. OLS regression analysis reveals that the model's independent variables explain little dental price variation. No variable is consistently significant across services, but market area, coinsurance rates, and time costs alternately dominate across equations. These results suggest that, among adult insureds, coinsurance and time costs influence dental fees in a minority of dental services. Insurance reduces the patient's sensitivity to money price, and non-price factors correspondingly seem to become more important in patient search.

    Postmortem photography is a widespread practice in perinatal bereavement care, yet few studies have explored how it affects bereaved parents, or how it might be received by parents of older children. This study is an examination of the meaning, utility, and social context of postmortem photography in a sample of 181 bereaved parents. Data were subjected to both quantitative and qualitative analysis. Photographs were positively regarded by most parents after perinatal death and several parents of older children. Other parents rejected postmortem photography for aesthetic, personal, or cultural reasons. Brief recommendations are offered for healthcare providers.

    1970-01-01

    The use of lunar surface photography to achieve the photogrammetric transfer of available selenographic coordinates from future lunar landing sites to neighboring, photoidentifiable features was investigated. It can be implied from the procedures developed that overhead photography, were it available, could be utilized and would provide a material strengthening of the total solution. By the methodic selection of features and confirmation that they can in reality be identified from orbital photography, a modest selenodetic control system can be expanded into a net that could ultimately control all future, manned or unmanned, orbital photographic missions.

    Interpretations of photography of Orientale Basin deposits obtained under earthshine illumination conditions during the Apollo 16 mission are presented. Although the quality of these photographs is less than that obtainable in sunshine, these regions are in the dark during Apollo missions because of the locations of the Apollo landing sites. Photography of these regions under different lighting geometry and from different viewpoints is therefore a useful addition to previous photographic data. Oblique photography was obtained of Riccioli Crater and adjacent areas, which lie northeast of the Orientale Basin.

    Red Hill Studio and World View of Global Warming co-developed apps for the iPad and iPhone which graphically show climate-driven changes in repeat photographs and maps. The climate app, with 17 interactive screens that show climate changes to glaciers, coasts, rivers and world temperature, reaches a new part of the public, was featured in USA Today and is used in schoolrooms and museums. It led a list of top ten climate apps for 2012. The low price for this app encourages more users and income is being shared with the Union of Concerned Scientists. Red Hill Studio is also developing an app which is an aid for making time series and repeat photography. The Now & Then Cam app will allow scientists and citizens to take closely aligned repeat photos by overlaying the iPad/iPhone's camera image on top of an archival photo. This guides the photographer back towards the original location of the archival shot - leading to a more carefully aligned repeat photograph. The developers hope this app will contribute to both scientific and artistic creation of time-series photographs, an important and persuasive visualization of change. The Painting with Time and Now & Then Cam apps build upon a traveling museum exhibition, Playing with Time, and an international documentary special, Exploring Time, that were developed by Red Hill Studios under grants from the National Science Foundation. The app programmers, Charlie Brown and J.A. Nelson, use Objective C to create fluid, responsive interfaces with no distracting latencies or delays. World View of Global Warming is an independent photojournalistic documentation of global warming and rapid climate change begun in 1999. Repeat and time-series photography is an integral part it its climate communication.

    Formal teaching and training in medical photography at Cardiff started in 1969 when a School of Medical Photography was established, as part of the Department of Medical Illustration, at the Cardiff Royal Infirmary. In the early 1970s the school was transferred with the Medical Illustration Department to the newly built University Hospital of Wales, and housed in planned accommodation at what is now the Institute of Health Care Studies. The school offered courses in medical photography at the level of the qualifying examinations of the Professional Institutes, to suitably qualified in-service students appointed to the Medical Illustration Department as Trainee Medical Photographers. In 1990, the University of Wales approved a Master of Science course in Medical Illustration (Photography and Video) offered by the school. The course is available both to in-service students of the school and to practising medical photographers as mature students on a distance learning programme. Details of the new course and its delivery are given.

    2005-06-01

    Clinical photography in the late 19th century aimed at unveiling the hidden processes invisible to the clinical eye. Changes in the outer form hinted at deeper lying causes, and decoding these forms was supposed to extend the range of the clinical eye in to the realm of invisibility. Two suppositions supported this hope: the belief that each disease as an ontological entity showed typical exterior signs which allowed a diagnosis at sight, and the technological trust in photography as a precise and objective means of representation superior to the human eye. For a short time, clinical photography seemed to be the 'via regia" of diagnosis. Heinrich Curschmann's Klinische Abbildungen and Ludwig Jankau's periodical Internationale medizinisch-photographische Monatsschrift marked the climax of this development in Germany. Röntgen's discovery and its immediate application in clinical medicine put an end to the optimistic expectations: clinical photography was from now on only one among many different means of documenting clinical signs and findings.

    1974-01-01

    The author has identified the following significant results. With the advent of ERTS and Skylab satellites, multiband imagery and photography have become readily available to geologists. The ability of multiband photography to discriminate sedimentary rocks was examined. More than 8600 in situ measurements of band reflectance of the sedimentary rocks of the Front Range, Colorado, were acquired. Statistical analysis of these measurements showed that: (1) measurements from one site can be used at another site 100 miles away; (2) there is basically only one spectral reflectance curve for these rocks, with constant amplitude differences between the curves; and (3) the natural variation is so large that at least 150 measurements per formation are required to select best filters. These conclusions are supported by subjective tests with aerial multiband photography. The designed multiband photography concept for rock discrimination is not a practical method of improving sedimentary rock discrimination capabilities.

  20. From photography to cinematography: recording movement and gait in a neurological context.

    PubMed

    Aubert, Geneviève

    2002-09-01

    The major challenge of photography has been freezing movement, to transform it into a fixed image or series of images. Very soon, photographers became interested in movement itself and tried to use photography as a tool to analyze movement. At the early stages, physicians interested in movement, perhaps surprisingly, made important technical contributions. Mécanisme de la physionomie humaine, by Duchenne, the first book with physiological experiments illustrated by photographs, is a landmark in this historical development. At the Salpêtrière, thanks to Charcot, photography officially entered clinical neurology. Medical journals with photographs were actively developed by Bourneville. Londe established a clinical photographic laboratory and published the first book on medical photography. The study of animal and human movement by Muybridge and Marey in the 1880s led to chronophotography and later cinematography. Clinicians such as Dercum and Richer took advantage of these new techniques to study pathological movement and gait in neurological diseases. PMID:12481476

    The purpose of the present investigation was to study the utilization of dental services, the distribution of dental diseases and treatment needs in a Danish industrial population. The study covered the male population at a Danish shipyard, and a sample of 988 workers and clerical and managerial staff was drawn by stratified random sampling. 841 persons were interviewed regarding dental visits and attitudes towards dental health services and data on dental health and treatment needs were collected. 61% of the participants aged 15-64 years made regular dental visits at least once a year. The percentages of regular visitors varied according to age and occupation, from 68 to 82% among clerical staff to 34 to 51% among workers. The mean DMF-T increased from 16.6 in the age group 15-24 to 27.0 among the 55-64-year-olds. Untreated dental decay was predominant among workers and persons never seeing a dentist, whereas there were more filled teeth and fewer missing teeth among staff and regular visitors. The periodontal status was less satisfactory in the older age groups and among workers, and most denture wearers were found in the age group 35-64 and among workers. Concordant to the findings on dental health status, dental treatment needs due to caries and periodontal disease as well as prosthetic treatment needs varied according to age, occupation and dental visits. More radical treatment types were needed in the older age groups, among workers and non-regular visitors. The present study seems to indicate that dental diseases in the adult Danish population are not under control.

The second aim was to assess whether one group of dental students' experiences with dental hygiene student peer teaching affected their perceptions of the dental hygiene profession. Survey respondents were 57 dental hygiene students in all three years of the program (response rate 60% to 100%); 476 dental students in all four years (response rate 56% to 100%); 28 dental and dental hygiene graduate students (response rate 28%); and 67 dental and dental hygiene faculty members (response rate 56%). Compared to the other groups, dental students reported the lowest average number of services dental hygienists can provide (p≤0.001) and the lowest average number of patient groups for which dental hygienists can provide periodontal care (p<0.001). Dental students also had the least positive attitudes about clinical interactions between dental hygiene and dental students (p<0.001) and perceived the fewest benefits of dental hygiene student peer teaching (p<0.001) before experiencing peer teaching. After experiencing dental hygiene student peer teaching, the dental students' perceptions of dental hygienists' roles, attitudes about clinical interactions with dental hygienists, and perceived benefits of dental hygiene student peer teachers improved and were more positive than the responses of their peers with no peer teaching experiences. These results suggest that dental hygiene student peer teaching may improve dental students' perceptions of dental hygienists' roles and attitudes about

Dental students also had the least positive attitudes about clinical interactions between dental hygiene and dental students (p<0.001) and perceived the fewest benefits of dental hygiene student peer teaching (p<0.001) before experiencing peer teaching. After experiencing dental hygiene student peer teaching, the dental students' perceptions of dental hygienists' roles, attitudes about clinical interactions with dental hygienists, and perceived benefits of dental hygiene student peer teachers improved and were more positive than the responses of their peers with no peer teaching experiences. These results suggest that dental hygiene student peer teaching may improve dental students' perceptions of dental hygienists' roles and attitudes about

    Dental science researchers do not really need a detailed, ready-at-hand knowledge of statistics to design and perform high quality scientific research. Although the acquisition and utilization of such knowledge by dental researchers is not discouraged, it is proposed that it is more important for dental researchers to be committed to developing and maintaining a long term, ongoing, interactive consulting relationship with a biostatistician. The nature of this relationship will depend in large part on the complexity of the dental research being conducted. While the statistical consultant will assist in interpreting analytic results for the dental researcher, the latter will need to provide extensive input in assisting in the estimation of sample size and power, and for expressing scientific hypotheses in statistical terms so that the appropriate data analytic methodology can be specified.
