    Successful breastfeeding is dependent upon an infant's ability to correctly latch onto a mother's breast. If an infant is born with oral soft tissue abnormalities such as tongue-tie or lip-tie, breastfeeding may become challenging or impossible. During the oral evaluation of an infant presenting with breastfeeding problems, one area that is often overlooked and undiagnosed and, thus, untreated is the attachment of the upper lip to the maxillary gingival tissue. Historically, this tissue has been described as the superior labial frenum, median labial frenum, or maxillary labial frenum. These terms all refer to a segment of the mucous membrane in the midline of the upper lip containing loose connective tissue that inserts into the maxillary arch's loose, unattached gingival or tight, attached gingival tissue. There is no muscle contained within this tissue. In severe instances, this tissue may extend into the area behind the upper central incisors and incisive papilla. The author has defined and identified the restrictions of mobility of this tissue as a lip-tie, which reflects the clinical attachment of the upper lip to the maxillary arch. This article discusses the diagnosis and classifications of the lip-tie, as it affects an infant's latch onto the mother's breast. As more and more women choose to breastfeed, lip-ties must be considered as an impediment to breastfeeding, recognizing that they can affect a successful, painless latch and milk transfer.

    Two cases where aberrant tissue was attached to the lower lip mimicking the inferior labial frenum were reported. The frenum-like tissue extended from the gingival margin between the lower left deciduous central and lateral incisors in case 1 and between the lower right deciduous central and lateral incisors in case 2, to the dry lower lip. Histologically, the resected specimen was regarded as normal oral mucosa covered with stratified squamous epithelium, without a clear amniotic band. The frenum-like tissue of the lower lip found in both our patients was diagnosed as a category of oral synechiae, of unknown origin. PMID:26780195

    Introduction A torn labial frenum is widely regarded as pathognomonic of abuse. Methods We systematically reviewed the evidence for this, and to define other intra‐oral injuries found in physical abuse. Nine studies documented abusive torn labial frena in 30 children and 27 were fatally abused: 22 were less than 5 years old. Only a direct blow to the face was substantiated as a mechanism of injury. Results Two studies noted accidentally torn labial frena, both from intubation. Abusive intra‐oral injuries were widely distributed to the lips, gums, tongue and palate and included fractures, intrusion and extraction of the dentition, bites and contusions. Conclusions Current literature does not support the diagnosis of abuse based on a torn labial frenum in isolation. The intra‐oral hard and soft tissue should be examined in all suspected abuse cases, and a dental opinion sought where abnormalities are found. PMID:17468129

    The aim of this study was to determine the prevalence of midline diastema, tongue tie and frenum attachments amongst school children in Nairobi. A total of 1802 children aged between 4 and 16 years were selected randomly using multistage sampling technique. To avoid oversampling in either sex, a proportionate sampling procedure was used. Thereafter, a thorough intra-oral examination was carried out using a mouth mirror under artificial or natural light with the children lying on a supine position. Presence or absence of midline interdental spaces unusually bigger than other interdental spaces were noted and recorded on a prepared dateacollection form. Accurate location of the origin of the frenum was done using Placek et al Morphological-functional classification of the labial frenum attachments. Data was analyzed manually by tally method. Results showed that 35% had upper and lower midline diastema. 55% were females and 45% were males. Their mean age was 7.6 years. 0.2% had a high lingual frenum. The commonest location of frenum attachment amongst children with lower midline diastema was the mucogingival junction (86%) whereas amongst those with upper midline diastema it was attached gingiva (50%). None of the children had frenum attachment on the interdental papilla. It was concluded that the maxilla had a higher prevalence of midline diastema than the mandible and that papillary penetrating frenum attachments amongst these patients were higher in the maxilla than the mandible.

    The labial frenum may impede oral hygiene and result in diastema between anterior teeth and traction of the attached gingiva. Surgical removal of the frenum during puberty has been recommended for these patients. This article clinically evaluates the efficacy of an Er,Cr:YSGG laser in removing the labial frenum in an adolescent and pre-pubescent population. Using an Er,Cr:YSGG laser at a power setting of 1.5 W or less and 20 to 30 pulses per second, a total of 156 frenectomies were performed on 143 children. Patients returned for recall visits at 3, 7, 21, and 30 days and at one, two, and three years. Surgical areas were checked for adverse events, recurrency of frenum, and functional complications. Patient acceptance was also evaluated by using the Wong-Baker FACES pain rating scale. Thirteen recurrences were reported in the adolescent population at 21 or 30 days, all of which required re-intervention; however, only two cases displayed recurrence of the frenum. None of the three pre-pubescent cases required additional intervention, maintaining acceptable clinical results after three years. Patient acceptance was very high, and no postoperative adverse events were reported. PMID:20478790

    Ankiloglossia or frenum lingual alteration leads to important tongue dysfunction, which, besides discomfort and pain during function, is generally responsible for the difficulty to express specific phonemes. In other cases, a heavy muscular abnormal attachment of labial frenum can promote clinical changes. In such case, an eventual orthodontic therapy is indicated and aesthetic alteration is observed. In both cases, surgical removal is indicated. The surgery, for prevention purposes, must be done as soon as possible, but considering that the majority of patients are young (5 - 14 years old), difficulties during surgery are expected to occur. Correction of speech or orthodontic dysfunction in advanced ages is much more complex and difficult than in childhood. In the present work we demonstrate that the use of CO2 lasers in these cases are advantageous and simple. The laser energy causes the tissue of the frenum to open in the classic shape with no bleeding and no need for suture, reducing the risk of cross- contamination and of postoperative infection. Scarring and other complications are also minimized. A CO2 laser (continuous, 8 W, 10.6 micrometers) was used assisted with local anesthesia. The major advantage of laser is the possibility of its application in early ages, preventing further problems.

    To report a rare case of a lateral frenum hypertrophy in an infant, this paper describes the case of a girl who came to a first dental appointment when she was 4 months old. A hypertrophic lateral frenum in the upper left canine region was detected. A great depression in the gingival rodet separated the anterior maxillary segment from the posterior one and also decreased the lip mobility in this region. A frenectomy was performed when the patient was 11 months old and the clinical follow-up was done up to the age of 30 months. There was normalization in the vestibular insertion of the lateral frenum, lip mobility, physiological development of the maxilla, and eruption of the upper incisors, canines, and first primary molars. Infants should go to a dental examination precociously in order to detect possible congenital and development alterations. PMID:25180104

    Introduction  Altered lingual frenum modifies the normal tongue mobility, which may influence the stomatognathic functions, resulting in anatomical, physiological and social damage to the subject. It is necessary that health professionals are aware of the process of evaluation, diagnostics and treatment used today, guiding their intervention. Objective  To perform a systematic review of what are the treatment methods used in cases of lingual frenum alteration. Data Synthesis  The literature searches were conducted in MEDLINE, LILACS, SciELO, Cochrane and IBECS, delimited by language (Portuguese, English, Spanish), date of publication (January 2000 to January 2014) and studies performed in humans. The selection order used to verify the eligibility of the studies were related to: full text availability; review the abstract; text analysis; final selection. Of the total 443 publications, 26 remained for analysis. The surgical approach was used in all studies, regardless of the study population (infants, children and adults), with a range of tools and techniques employed; speech therapy was recommended in the post surgical in 4 studies. Only 4 studies, all with infants, showed scientific evidence. Conclusion  Surgical intervention is effective for the remission of the limitations caused by the alteration on lingual frenum, but there is a deficit of studies with higher methodological quality. The benefits of speech therapy in the post surgical period are described from improvement in the language of mobility aspects and speech articulation. PMID:27413412

    Labial adhesions, also known as labial agglutination, are a common finding in prepubertal adolescents. They are defined as fusion of the labia minora in the midline or are termed vulvar adhesions when they occur below the labia minora (inner labia). Patients are often asymptomatic but might present with genitourinary complaints. The decision for treatment is based on symptoms. The mainstay of treatment in asymptomatic patients is conservative, with careful attention to vulvar hygiene and reassurance to parents. In symptomatic patients, topical treatment with estrogen and/or steroid cream is often curative. Less often, corrective surgery is necessary. Recurrence is common until a patient goes through puberty. These recommendations are intended for pediatric and gynecologic health care providers who care for pediatric and adolescent girls to facilitate diagnosis and treatment. PMID:26162697

    Clinical implication The purpose of this study is to record the vertical distance between anterior attachment of lingual frenum and incisal edge of mandibular central incisors in dentulous subjects and then determine the mean vertical distance and to suggest guidelines for positioning of mandibular central incisors in complete dentures. Method In this study, 150 dentulous subjects (75 males and 75 females) were chosen based on predecided inclusion criteria. A mandibular cast was obtained from irreversible hydrocolloid impression in modified stock trays for each subject. All subjects were instructed to elevate the tongue while the impressions were made. The vertical distance between the anterior attachment of the lingual frenum and incisal edges of mandibular central incisors was measured on the casts and then the values were statistically analyzed. Result The distance between anterior attachment of lingual frenum (AALF) mesioincisal edge of mandibular central incisor (CI) in male, female and total (male + female) subjects was measured. In males it ranged from 7.3 to 8.9 mm with mean (±SD) 8.29 ± 0.36 mm while in females it ranged from 7.1 to 9.0 mm with mean (±SD) 8.21 ± 0.38 mm. Conclusion It is believed that the application of this anatomic relation can provide a reliable point for arranging and checking the position of the mandibular central incisors for complete dentures in patients with class I ridge relationship.

    Labial adhesions after puberty are rare and are usually the result of chronic inflammation, urinary tract infection, hypoestrogenism or surgical procedures leading to vulval trauma. Sexual abuse leading to labial adhesions is extremely rare in girls who have attained menarche. Complete vulval fusion can rarely occur without any evidence of hypoestrogenism. We address this rare entity in three young pubertal girls wherein one had a history of genital trauma, the second had a history of surgical intervention due to urinary retention and the last one had a history of sexual abuse. All patients had history of genital trauma in common. Accepted management of this condition is adhesiolysis followed by application of estrogen cream in the postoperative period. PMID:16189695

  12. A labial gesture for /l/

    Both in language change and in substitutions during language acquisition and disordered speech, /l/ has often been observed to alternate with labial sounds such as [w] or rounded vowels, particularly in postvocalic position. While there are many possible explanations for this alternation, including acoustic enhancement and articulator coupling, one possibility that has not been tested is whether normal adult speakers of English actually produce lip rounding for /l/. A study was conducted to test for the presence of a labial gesture in normal productions of /l/. Front and side video data of lip positions were collected from three adult English speakers during productions of /l/ and /d/. Significant differences were found for all subjects in lip protrusion (upper and lower) and/or lip aperture (horizontal and vertical) in post-vocalic allophones, as well as between the pre- and post-vocalic allophones of /l/. No significant differences were observed in comparisons of pre-vocalic /l/ and /d/. Results suggest that there is in fact a labial gesture in the post-vocalic allophone of /l/, but not in the pre-vocalic allophone. These findings are consistent with a notion of gestural simplification as a possible explanation for substitutions and in language change. [Research supported by NSERC.

  13. Leukoplakia of the labial commissure.

    A white lesion located in the labial commissure can pose problems for both the clinician and the pathologist. The clinician may be limited in his surgical treatment because of aesthetic reasons, whilst the pathologist may be confronted with a lesion with or without candidal involvement, showing the histological features of hyperplastic candidiasis, verrucous hyperplasia, verrucous carcinoma, epithelial dysplasia, carcinoma-in-situ and, occasionally, squamous cell carcinoma. A retrospective study was undertaken of 10 patients with leukoplakic commissural lesions, who visited the Department of Oral Surgery in the Teaching Hospital of the Free University, Amsterdam in the period between 1973-1986. The clinical and histopathological findings are presented. Although a carcinoma in this particular region is rather rare, alertness remains necessary as one patient with the clinical appearance typical of leukoplakia, showed on biopsy the presence of a squamous cell carcinoma at this first visit. In another two patients the areas of leukoplakic change were shown histologically to be based on verrucous carcinoma. In one patient a squamous cell carcinoma developed after several years, in spite of treatment. In view of the small number of patients under discussion and also the somewhat debatable diagnosis of verrucous carcinoma, we do not feel justified in drawing any firm conclusions from our findings with regard to the malignant potential of leukoplakia of the oral commissures.

  15. Silks produced by insect labial glands.

    PubMed

    2008-01-01

    Insect silks are secreted from diverse gland types; this chapter deals with the silks produced by labial glands of Holometabola (insects with pupa in their life cycle). Labial silk glands are composed of a few tens or hundreds of large polyploid cells that secrete polymerizing proteins which are stored in the gland lumen as a semi-liquid gel. Polymerization is based on weak molecular interactions between repetitive amino acid motifs present in one or more silk proteins; cross-linking by disulfide bonds may be important in the silks spun under water. The mechanism of long-term storage of the silk dope inside the glands and its conversion into the silk fiber during spinning is not fully understood. The conversion occurs within seconds at ambient temperature and pressure, under minimal drawing force and in some cases under water. The silk filament is largely built of proteins called fibroins and in Lepidoptera and Trichoptera coated by glue-type proteins known as sericins. Silks often contain small amounts of additional proteins of poorly known function. The silk components controlling dope storage and filament formation seem to be conserved at the level of orders, while the nature of polymerizing motifs in the fibroins, which determine the physical properties of silk, differ at the level of family and even genus. Most silks are based on fibroin beta-sheets interrupted with other structures such as alpha-helices but the silk proteins of certain sawflies have predominantly a collagen-like or polyglycine II arrangement and the silks of social Hymenoptera are formed from proteins in a coiled coil arrangement.

    Background: Labial adhesion is one of the most common reasons for gynaecologic consultations in children. We sought to determine the prevalence of labial adhesions, mode of presentation and treatment in children at the Jos University Teaching Hospital. Materials and Methods: A retrospective study of labial adhesions in children from January 2004 to December 2013. Data on paediatric gynaecological consultations, and labial adhesions were retrieved from the gynaecological clinic and the theatre records. The case notes of those with labial adhesions were retrieved and the relevant data extracted. Results: The total number of paediatric patients seen at the gynaecology clinic over the study period was 379 and 25 had labial adhesion (6.6%). The majority (88%) presented in the first 2 years of life, all the patients were asymptomatic, and 2 (8%) had surgical separation of the adhesions while the rest were managed conservatively. A total of 5 (20%) came for follow-up. While 2 (8%) came a week later following surgical management, 3 (12%) came back more than 6 months later due to recurrence following conservative management. Conclusion: Labial adhesions account for significant proportion of paediatric gynaecologic consultations. They are usually asymptomatic, occur in the first 2 years of life and frequently managed conservatively. PMID:27251516

    Labial glands are present in all castes and developmental stages of all termite species. In workers, their secretion contains a food-marking pheromone and digestive enzymes, while soldier secretion plays a defensive role. However, these functions were studied only in a limited set of species, and do not allow drawing general conclusions. Hence, we have investigated the chemical composition of the labial gland extracts from soldiers and workers in 15 termite species belonging to 6 families using an integrative approach based on proteomic and small-molecule profiling. We confirmed the presence of hydroquinone and cellulase in the labial glands of workers, and we identified new toxic compounds in soldiers and workers of several species. Our results highlight the dual role of labial gland secretion, i.e. the defensive role in soldiers and workers of several termite species, and the digestive function in workers. PMID:23071569

    Labial fusion is benign genital disorder, which more frequent in children at 6 years old and less in women in reproductive and postmenopausal age. It can be congenital or acquired condition. Its etiology is unclear. The low serum estrogen concentration is the basic cause of labial fusion. As a result of physiological hypoestrogenism in the vulvar skin and mucosa come on atrophic changes, which together with the chronic inflammatory changes lead to labial adhesia with subsequent partial or total obstruction of the vagina and/or the urethra. The treatment can be conservative or surgical depending on the degree of labial fusion. We perform two clinical cases respectively of total and partial vulvarsynechiae in postmenopausal women. The clinical picture of the patient with total synechiae is represented by a difficult and prolonged micturition and urinary incontinence, while in patients with partial synechiae is represented by an inability to carry out sexual intercourse.

  20. Representing female desire within a labial framework of sexuality.

    PubMed

    Schiller, Britt-Marie

    2012-12-01

    Sexual experiences, rather than being neutral, are specifically male or female. Yet at present no conceptual framework exists for representing female sexual desire. This has resulted in frequent misrepresentations of female sexual experience. To correct this, a labial framework is proposed, not to replace or oppose a phallic framework, but to exist alongside it. The lips of the mouth and those of the genitals provide a felicitous doubling of sexuality and speech to represent female desire and sexual pleasure as labial. Phallic and labial rhythms are organized differently in sexual arousal and desire, since, as Simone de Beauvoir put it, "Man 'gets stiff,' but woman 'gets wet.'" The labial framework therefore represents female psychosexuality more in terms of "wetware" than of "hardware." PMID:23118235

    2014-12-01

    Labial adhesion is a thin membranous fusion of the labia minora of varying length. It is not a rare condition in prepubertal girls, but since it is often asymptomatic, it remains undiagnosed. It is usually discovered during regular check-ups or when the fusion results in post-void dripping, bacteriuria, vaginal irritation, dysuria, urinary tract infection or obstruction. The cause of labial adhesions is unclear. Chronic irritation of the vulva in combination with poor hygiene is believed to be important etiologic factors. A theory of hypoestrogenic status in prepubertal girls as a potential etiologic factor for labial adhesions is no longer widely accepted, since a recent study concluded that there was no difference in estrogen levels between children with and those without labial adhesions. Treatment options include conservative management with topical estrogen or betmethasone creams or, when indicated, manual separation or surgery. Topical estrogen and betamethasone creams are generally considered safe and effective treatment of labial adhesions, even over prolonged periods of time, with minimal if any side effects. No guidelines have been structured for the limits or duration of topical therapy, but most authors agree that optimal treatment should last from 1 to 2 or 3 months on twice-a-day regimen. Parental education concerning appropriate application technique is important not only for the success of treatment, but also to avoid the possible side effects. PMID:26285472

    The earthworm provides an excellent model for investigating regeneration. Here we report the full-length cloning of three labial genes (Pex-lab01, Pex-lab02, and Pex-lab03) in the earthworm Perionyx excavatus. To analyze their expression pattern during head and tail regeneration, we used the reverse transcription-polymerase chain reaction. Our results indicate that the three labial genes were expressed only in the head-regenerating tissues. Also, we found that the expression of Pex-lab01 and Pex-lab02 is up-regulated, and this indicates their involvement in wound healing and the blastema formation processes during early head regeneration.

    Calibre persistent labial artery (CPLA) usually presents as an asymptomatic papule on the lower lip and can be easily misdiagnosed as a mucocele, haemangioma, venous lake, varix or fibroma. When it is ulcerated, squamous cell carcinoma is the most usual differential diagnosis. Here, we report a case of a 25-year-old woman with no previous relevant medical history who presented with a complaint of an asymptomatic, non-ulcerated, progressively growing nodule (over the last 5 months) on the upper lip. In this case, the diagnosis was made clinically and confirmed by immunohistochemical analysis. We conclude that clinicians should be aware of CPLA and it should be included in the differential diagnosis of labial mucosal papules. Sometimes, the immunohistochemical analysis is necessary to make a correct diagnosis. PMID:26225087

    Oral mucoceles are common lesions characterized by accumulation of mucus following rupture of a minor salivary gland duct. However, congenital mucoceles are a rare and distinctive oral condition observed in newborns. This case report details the features of a congenital labial nodule diagnosed as congenital mucocele. These lesions are rare in the oral cavity and should be diagnosed in the delivery room, but many cases are referred for further evaluation. Management is simple, and recurrence is not expected.

    1998-09-01

    Sixteen cases of caliber-persistent labial artery of the lips have been reported to date in the English literature. Six of these were clinically misdiagnosed as squamous cell carcinoma and treated with wedge resection. To date, we have seen 187 cases clinically and an additional 23 cases through our surgical oral pathology services. Careful clinical observation usually reveals a soft linear or papular bluish elevation above the labial mucosal surface. The unique feature is pulsation--not simply pulsation toward and away from the observer, which can be caused by an underlying artery, but lateral pulsation, which only an artery can exhibit. All but 2 of our 187 clinical cases were asymptomatic. To the best of our knowledge, this is the first report of caliber-persistent labial artery of the upper lip. The upper:lower lip ratio for the clinical cases was almost 2:1. Three times as many lower lip as upper lip lesions were biopsied. Males and females were almost equally affected (clinical cases, 76:86; histopathologic cases, 9:13). Although a vascular term (artery, hemangioma, phlebolith, varix, vascular malformation) was used on the biopsy form in one half of the clinical differential diagnoses, none of the clinical histories mentioned pulsation. In contrast to the cases of Miko et al. in 1980 and 1983, none of our cases manifested itself as an ulcer, nor was carcinoma ever mentioned in the clinical differential diagnosis. The purpose of this article is to familiarize clinicians and pathologists with the clinical and histopathologic features of this seldom reported but common vascular anomaly. Clinicians should carefully look for lateral pulsation in lip mucosal papules so as to avoid unnecessary surgery and intraoperative arterial bleeding. Pathologists should recognize that a relatively large-caliber superficial artery in a lip biopsy may not be an incidental finding but rather the clinical lesion that was biopsied. PMID:9768420

    Pyogenic granuloma is thought to represent an exuberant tissue response to a local irritation or trauma. It is a reactional response to constant minor trauma and it might be related to hormonal changes. Clinically, these lesions usually present as single nodules or sessile papules with smooth or lobulated surfaces. These may be seen in any size, from a few millimetres to several centimetres. Pyogenic granuloma of the oral cavity is known to involve the gingiva more commonly (75% of all the cases). An extragingival occurrence of pyogenic granuloma is rare. This paper has described an extragingival pyogenic granuloma which occurred on the upper labial mucosa in a 30 years old female patient. PMID:23905151

    The present study provides new data concerning the morphology and distribution of the labial sensilla of 55 species of 12 nepomorphan families (Heteroptera: Nepomorpha) using the scanning electron microscope. On the labial tip, three morphologically distinct types of chemosensilla have been identified: two types of papillae sensilla and one type of peg-in-pit sensilla. Twenty-one morphologically distinct types of the mechanosensilla as well as two types of the trichoid sensilla (contact-chemoreceptive sensillum) have been identified on all labial segments in representatives of subfamilies. In Nepomorpha, morphological ground plan of the labial sensory structures is represented by an apical sensory field with 10–13 pairs of papillae sensilla and the peg-in-pit ones placed more laterally; numerous trichoid sensilla are placed on the IV segment; the chaetica sensilla are present and placed in groups or rows distributed along the labium near the labial groove on the dorsal side, and also several chaetica sensilla are unevenly scattered on the surface of that segment; the cupola and peg sensilla are numerous and evenly scattered on the fourth labial segment; the prioprerecptive sensilla, one pair is positioned on the dorsal side and on the fourth segment of the labium. The new apomorphical characters have been established for the labial sensilla in the Nepomorpha. PMID:23935421

    The labial thermistor offers several potential psychometric advantages over existing measures of female sexual response; however, the thermistor lacked data to support these presumed advantages, especially with respect to its discriminant validity. In this study, both the labial thermistor was worn simultaneously with the vaginal photoplethysmograph as women viewed films. They also indicated their level of subjective sexual arousal using a lever. The labial thermistor discriminated sexual from nonsexual arousing stimuli and was sensitive to different levels of sexual arousal. The correspondence of the instrument with subjective sexual arousal, measured using a continuous lever, was lower during the mildly arousing sexual film and higher during the maximally sexual arousing film. One woman reported that the labial thermistor was very uncomfortable, while others indicated no or mild discomfort from each instrument. The vaginal photoplethysmograph largely replicated the effects documented by the labial thermistor, although it did not discriminate sexual stimuli of different intensity nor correspond with women's continuous lever responses as closely during the more arousing stimulus. Difficulties recording simultaneously with these instruments are noted. The labial thermistor adequately discriminates between generally arousing and sexually arousing stimuli, increasing its utility as a measure for between-subject study designs. PMID:19041673

    The effect of tuning slots on the sound characteristics of labial organ pipes is investigated in this paper by means of laboratory experiments. Besides changing the pitch of the pipe, the tuning slot also plays an important role in forming the timbre. The objectives of this contribution are to document the influence of tuning slots built with different geometries on the pipe sound and to validate the observed tendencies by means of reproducible experiments. It is found that the measured steady state sound spectra show unique characteristics, typical only for tuning slot organ pipes. By separately adjusting the geometrical parameters of the tuning slots on experimental pipes, the impact of each scaling parameter on the steady state spectrum is determined. It is shown that the scaling procedures used currently in organ building practice do not provide sufficient control over the sound characteristics, leaving the capabilities provided by the tuning slot unexploited. Subjective comparison made by organ builders of sound recordings of various setups confirms that the observed sound quality of tuning slot pipes is strongly dependent on the scaling of the slot.

    2010-01-01

    Hox transcription factors play an essential role in patterning the anteroposterior axis during embryogenesis and exhibit a complex array of spatial and temporal patterns of expression. Their earliest onset of expression in vertebrates is during gastrulation in a temporally collinear sequence in the presomitic/ventrolateral mesoderm, and it is not clear which upstream signal transduction events initiate this expression. Using Xenopus, we present evidence that Xwnt8 is necessary for initiation of this collinear sequence by activating Hox-1 expression in three Hox clusters: hoxd, hoxa, and hoxb. All three labial genes appear to be direct targets of canonical Wnt signaling through Tcf/Lef. In addition, Xwnt8 loss- and gain-of-function leads to indirect regulation of other Hox genes: Hoxb4, Hoxd4, Hoxa7, Hoxc6, and Hoxc8. These findings shed new light on the early role of Wnt8 as well as of a proposed WNT gradient in patterning the Xenopus central nervous system (Kiecker and Niehrs [2001] Development 128:4189-4201).

    Adult moths possess an organ in their labial palps, the labial-palp pit organ, which is specialized for sensing carbon dioxide (CO2). They use CO2 as a cue to detect healthy plants and find food or lay eggs on them. The molecular bases of the CO2 receptor in Drosophila melanogaster and Aedes aegypti have been reported, but the molecular mechanisms of the CO2 receptor in Lepidoptera remains elusive. In this study, we first re-examined three putative Helicoverpa armigera CO2 gustatory receptor genes (HarmGr1, HarmGr2, and HarmGr3), and then analyzed expression patterns of them. RT-PCR results verified they were predominantly expressed in the labial palps of H. armigera. Thus, we used in situ hybridization to localize the expression of three genes in the labial palps. We found that all three genes were co-expressed in the same cells of the labial palps. Next, we employed the Xenopus laevis oocyte expression system and the two-electrode voltage-clamp recording to study the function of the three genes. Results showed that only oocytes co-expressing HarmGr1 and HarmGr3 or co-expressing HarmGr1, HarmGr2 and HarmGr3 gave robust responses to NaHCO3. Finally, we confirmed that the sensory cells in labial palps of both females and males show dose dependent responses to CO2 stimuli by using single sensillum recording. Our work uncovers that HarmGr1 and HarmGr3 are indispensable and sufficient for CO2 sensing in labial palps of H. armigera. PMID:27060445

    X-ray microanalysis of freeze-dried labial gland cryosections revealed that Na concentration was doubled and the Ca/S concentration ratio was decreased in secretory granules of labial glands from patients with cystic fibrosis (CF) when compared with glands from normal subjects. Other results suggested that the decrease in the Ca/S concentration ratio resulted from an increase in S concentration. These findings imply that mucous granules in labial saliva showed a CF-related increase in Na and S content, and such changes would be expected to affect the rheology of the mucus after exocytosis. In contrast with a previous study in human parotid glands, no evidence was found for CF-related changes in cytoplasmic or nuclear Na, K, and Ca concentrations. Significant elemental differences were found between secretory granules and nuclei and cytoplasm of control cells.

    Human labial glands secrete mucous and serous substances for maintaining oral health. The normal microbial flora of the oral cavity is regulated by the acquired and innate immune systems. The localization and distribution of proteins of the innate immune system were investigated in serous acinar cells and the ductal system by the method of immunohistochemistry. Numerous antimicrobial proteins could be detected in the labial glands: β-defensin-1, -2, -3; lysozyme; lactoferrin; and cathelicidin. Cytoskeletal components such as actin, myosin II, cytokeratins 7 and 19, α- and β-tubulin were predominantly observed in apical cell regions and may be involved in secretory activities.

    The intercalary segment is a limbless version of the tritocerebral segment and is present in the head of all insects, whereas other extant arthropods have retained limbs on their tritocerebral segment (e.g. the pedipalp limbs in spiders). The evolutionary origin of limb loss on the intercalary segment has puzzled zoologists for over a century. Here we show that an intercalary segment-like phenotype can be created in spiders by interfering with the function of the Hox gene labial. This links the origin of the intercalary segment to a functional change in labial. We show that in the spider Parasteatoda tepidariorum the labial gene has two functions: one function in head tissue maintenance that is conserved between spiders and insects, and a second function in pedipalp limb promotion and specification, which is only present in spiders. These results imply that labial was originally crucial for limb formation on the tritocerebral segment, but that it has lost this particular subfunction in the insect ancestor, resulting in limb loss on the intercalary segment. Such loss of a subfunction is a way to avoid adverse pleiotropic effects normally associated with mutations in developmental genes, and may thus be a common mechanism to accelerate regressive evolution.

    The purpose of this pilot study was to begin characterizing changes in labial vibrotactile somatosensation in healthy older adults as a foundational step in determining how changes in orofacial sensation can affect functional behaviors, such as speech and feeding. Labial vibrotactile perception capacity of healthy older adults (n = 15) was compared to a cohort of healthy young adults (n = 5). Vibrotactile inputs were delivered to the glabrous surface of the left lower lip at 5, 10, 50, and 150 Hz. A modified von Bekesy (staircase) method was used to identify participants' thresholds and response standard deviations for each test frequency. Consistent with findings in other body regions, a decrease in labial vibrotactile detection sensitivity was expected in healthy older adults. The threshold values for the 5 and 10 Hz test frequencies were higher in the older group and the differences in response standard deviations at these frequencies were statistically significant. This pilot study identified changes in labial perception among healthy older adults. PMID:24897891

    The authors report a genioplasty technique in which the advancement of an anterior mandibular segment is executed with a specific osteotomy form that helps to avoid a deep mentolabial fold and improves labial competence. The osteotomy presented achieves this by creating a 'chin shield' where the mandibular segment advanced is relatively high on the side of the buccal cortex and lower on the lingual side and where the osteotomy or down-fracture in between is in an oblique angle in the sagittal plane.

    Background: The intensity and duration of speech difficulty inherently associated with lingual therapy is a significant issue of concern in orthodontics. This study was designed to evaluate and to compare the duration of changes in speech between labial and lingual orthodontics. Materials and Methods: A prospective longitudinal clinical study was designed to assess speech of 24 patients undergoing labial or lingual orthodontic treatment. An objective spectrographic evaluation of/s/sound was done using software PRAAT version 5.0.47, a semiobjective auditive evaluation of articulation was done by four speech pathologists and a subjective assessment of speech was done by four laypersons. The tests were performed before (T1), within 24 h (T2), after 1 week (T3) and after 1 month (T4) of the start of therapy. The Mann-Whitney U-test for independent samples was used to assess the significance difference between the labial and lingual appliances. A speech alteration with P < 0.05 was considered to be significant. Results: The objective method showed a significant difference to be present between the two groups for the/s/sound in the middle position (P < 0.001) at T3. The semiobjective assessment showed worst speech performance in the lingual group to be present at T3 for vowels and blends (P < 0.01) and at T3 and T4 for alveolar and palatal consonants (P < 0.01). The subjective assessment also showed a significant difference between the two groups at T3 (P < 0.01) and T4 (P < 0.05). Conclusion: Both appliance systems caused a comparable speech difficulty immediately after bonding (T2). Although the speech recovered within a week in the labial group (T3), the lingual group continued to experience discomfort even after a month (T4). PMID:25540661

    Immediate implant therapy involving implants placed into intact Type 1 extraction sockets has become a consistent clinical technique. The classification of Type 2 extraction sockets, where the mucosal tissues are present but there is a midfacial osseous dehiscence defect, has been described according to the extent of the buccal bone plate absence. The literature has offered different techniques in the treatment of Type 2 sockets; however, the extent of the defect has never been defined or delineated. In this article, the authors describe a subclassification of Type 2 sockets: Type 2A presents with a dehiscence defect roughly 5 mm to 6 mm from the free gingival margin (FGM) involving the coronal one-third of the labial bone plate; Type 2B presents with a dehiscence defect involving the middle one-third of the labial plate, approximately 7 mm to 9 mm from the FGM; and in Type 2C the dehiscence defect involves the apical one-third of the labial osseous plate roughly 10 mm or greater from the FGM. The authors also offer a protocol and technique employing immediate implant placement, guided bone regeneration, and bone graft containment with a custom two-piece healing abutment that can lead to consistent and satisfactory clinical outcomes in low-smile-line patients. The treatment protocol and sequence is outlined in a clinical case presentation involving a Type 2B socket. PMID:26247445

    Introduction Increasing numbers of women are seeking labial reduction surgery. We studied the motivations for considering labial reduction surgery as recounted on women's online communities and surgery provider's websites. Aims The study analyzed motivations for considering labial reduction surgery expressed by women on online communities, looked at the role of the women's age and nationality, compared findings with motivations indicated on the websites of an international sample of surgery providers, and identified similarities to and differences from what is known from extant studies. Methods Quantitative content analysis of the posts of 78 American, British, and Dutch women on online communities, and 40 international surgery providers' websites about labial reduction surgery was conducted. Main Outcome Measures Main outcome measures concerned the incidence and prominence of different motivational categories (functional/emotional and discomfort/enhancement related). Differences in motivations as a function of age, national background, and women's vs. surgeons' stated motivations were tested. Results Emotional discomfort regarding self-appearance and social and sexual relationships was found to be the most frequent and most prominent motivation for considering labial reduction surgery on women's online communities, regardless of age and national background. Functional discomfort and desired emotional enhancement ranked second. Very few age or national differences were found. The surgeons' websites recognized functional discomfort more and elaborated upon emotional issues in sexual relationships less than members of the online communities. Conclusions Feelings of emotional and psychosexual distress in addition to functional distress are a highly prevalent motivation among women considering labial reduction surgery. Emotional distress appears to be greater and more freely emphasized when women communicate on online communities, while functional issues appear to

    Topical calcineurin inhibitors are widely used to treat inflammatory dermatoses for their steroid-sparing advantage. Herein, we report a patient with chronic lip dermatitis who developed multiple labial melanotic macules after application of tacrolimus 0.1% ointment and pimecrolimus 1% cream. Prior and current reports raise concerns for potential development of pigmented lesions associated with topical calcineurin inhibitor use. These reports highlight the need for careful risk-benefit assessment when prescribing topical calcineurin inhibitors for inflammatory dermatoses, especially when used on sun-exposed sites.

    Ecthyma gangrenosum (EG) is a cutaneous infection most commonly associated with Pseudomonas aeruginosa sepsis. EG generally occurs in immunocompromised hosts, such as patients with severe neutropenia. EG presents as erythematous, hemorrhagic, or necrotic macules or plaques most commonly in the perineal or gluteal areas, but can occur elsewhere. EG is a dermatologic emergency in immunocompromised patients and should be included in the differential diagnosis when urologists are asked to evaluate perineal lesions. We describe the case of a highly immunocompromised infant with labial EG to highlight the importance of prompt clinical diagnosis and of multi-disciplinary medical and surgical management.

    The inguinal canal is traversed by the spermatic cord in men and the round ligament of uterus in women. The round ligament is attached to the uterine cornu near the origin of fallopian tube at one end and to the ipsilateral labia majora at the other. The round ligament accompanies a pouch of parietal peritoneum in the inguinal canal, which is known as 'canal of nuck'. It is analogous to the processus vaginalis in males. Incomplete obliteration of the peritoneal pouch causes indirect inguinal hernia or hydrocele of the canal of nuck; a very rare condition in women. As these types of cases are rarely seen in surgical practice we present a case of such little-known developmental disorder in a three-year-old girl. She presented with irreducible, tender right inguino-labial swelling with tachycardia simulating incarcerated inguinal hernia, which necessitates emergency surgical exploration. On exploration it was found to be an encysted hydrocele of canal of nuck; so although rare, this entity should be considered in differential diagnosis in a female child presented with inguino-labial swelling.

    Damage to periodontal tissue as a result of thermal injury often causes severe gingival recession and denuded alveolar bone. In this case report, two patients undergoing gingival coverage of iatrogenically denuded labial bone associated with the maxillary central incisor and the lateral incisor are presented. The first patient had gingival necrosis and labial alveolar bone exposure on the maxillary left central incisor and was referred from a local dental clinic. The patient had undergone root canal treatment 2 weeks previously. The gingival necrosis was assumed to be caused by a heated plugger. The denuded root surface was immediately covered by a laterally positioned flap over a connective tissue graft obtained from the palate. The gingival margin and overall appearance were symmetrically in harmony with those of the adjacent teeth. Another patient with the same symptoms and dental history was treated using the same procedure. Normal periodontal architecture was successfully reconstructed and maintained. In the cases presented, laterally positioned flap coverage over a subepithelial connective tissue graft was successfully applied to cover thermally injured bone and the root surface. PMID:23998159

    Malignant peripheral nerve sheath tumor (MPNST) is an uncommon soft tissue sarcoma with a predilection for the extremities and trunk of adults, rarely occurring in the oral cavity. To date, 10 cases of MPNSTs affecting the lower labial mucosa have been reported in the English language literature. We describe an additional case of MPNST in the lower labial mucosa of a 67-year-old male patient, who exhibited a painful swelling with a history of 4 months of evolution. Microscopic examination showed dense plexiform fascicles of spindle cells with wavy atypical nuclei. Mitotic figures and nuclear pleomorphism were evident. Immunohistochemical analysis of tumor cells revealed positivity for S-100 protein, CD56, CD34, and neuron-specific enolase but was negative for neurofilament protein, glut-1, claudin-1, desmin, and smooth muscle actin. Ki-67 labeling was 20%. The final diagnosis was MPNST. The lesion was surgically removed with wide margins, with no signs of recurrence after 4 years of follow-up. PMID:26852824

    Background/Aims Midgut formation in Drosophila melanogaster is dependent upon the integrity of a signaling loop in the endoderm which requires the TGFβ-related peptide, Decapentaplegic, and the Hox transcription factor, Labial. Interestingly, although Labial-like homeobox genes are present in mammals, their participation in endoderm morphogenesis is not clearly understood. Methods We report the cloning, expression, localization, TGFβ inducibility, and biochemical properties of the mammalian Labial-like homeobox, HoxA1, in exocrine pancreatic cells that are embryologically derived from the gut endoderm. Results HoxA1 is expressed in pancreatic cell populations as two alternatively spliced messages, encoding proteins that share their N-terminal domain, but either lack or include the homeobox at the C-terminus. Transcriptional regulatory assays demonstrate that the shared N-terminal domain behaves as a strong transcriptional activator in exocrine pancreatic cells. HoxA1 is an early response gene for TGFβ1 in pancreatic epithelial cell populations and HoxA1 protein co-localizes with TGFβ1 receptors in the embryonic pancreatic epithelium at a time when exocrine pancreatic morphogenesis occurs (days E16 and E17). Conclusions These results report a role for HoxA1 in linking TGFβ-mediated signaling to gene expression in pancreatic epithelial cell populations, thus suggesting a high degree of conservation for a TGFβ/labial signaling loop in endoderm-derived cells between Drosophila and mammals.

    Pyogenic granuloma is tumor-like proliferation to a nonspecific infection. Clinically, pyogenic granuloma presents as sessile or pedunculated exophytic mass with a smooth or lobulated surface which has a tendency to bleed easily. These lesions tend to occur slightly more in females, frequently involving the gingiva of the maxillary region. Histologically, these lesions show an excessive proliferation of vascular type of connective tissue to a nonspecific infection. The most common treatment is surgical excision with eradication of local irritants. This case report describes a pyogenic granuloma on the labial mucosa in a 33-year-old male, discussing the clinical features and histopathologic features that distinguish this lesion from other similar oral mucosa lesions.

    Temporary lingual and labial paraesthesia are not uncommon following the removal of mandibular third molar teeth. In patients with insulin-treated diabetes circum-oral paraesthesia is a common and important sign of impending hypoglycaemia. This report highlights the case of a 17-year-old girl with Type 1 (insulin-dependent) diabetes who, following the extraction of her four wisdom teeth, experienced minor circum-oral sensory disturbances. These effectively masked her early warning signs of impending hypoglycaemia which had hitherto allowed her to have very good glycaemic control. Trembling, sweating and loss of concentration became the new presenting symptom complex, which she found both disabling and worrying. Fortunately, within six months the paraesthesia had subsided and the patient was once again able to appreciate her usual warning symptom of impending hypoglycaemia. PMID:9718802

    Maxillofacial trauma in cats often results in mandibular symphyseal separation in addition to injuries of the caudal mandible and/or temporomandibular joint (TMJ). Caudal mandibular and TMJ injuries are difficult to access and stabilize using direct fixation techniques, thus indirect fixation is commonly employed. The immediate goals of fixation include stabilization for return to normal occlusion and function with the long-term objective of bony union. Indirect fixation techniques commonly used for stabilization of caudal mandibular and temporomandibular joint fracture/luxation include maxillomandibular fixation (MMF) with acrylic composite, interarcade wiring, tape muzzles, and the bignathic encircling and retaining device (BEARD) technique. This article introduces a modification of the previously described "labial reverse suture through buttons" technique used by Koestlin et al and the "labial locking with buttons" technique by Rocha et al. In cases with minimally displaced subcondylar and pericondylar fractures without joint involvement, the labial button technique can provide sufficient stabilization for healing. Advantages of the modified labial button technique include ease of application, noninvasive nature, and use of readily available materials. The construct can remain in place for a variable of amount of time, depending on its intended purpose. It serves as an alternative to the tape muzzle, which is rarely tolerated by cats. This technique can be easily used in conjunction with other maxillomandibular repairs, such as cerclage wire fixation of mandibular symphyseal separation. The purpose of this article is to demonstrate a modified labial button technique for maintaining occlusion of feline caudal mandibular fractures/TMJ luxations in a step-by-step fashion.

    Male marking pheromones (MPs) are used by the majority of bumblebee species (Hymenoptera: Apidae), including a commercially important greenhouse pollinator, the buff-tailed bumblebee (Bombus terrestris), to attract conspecific females. MP biosynthetic processes in the cephalic part of the bumblebee male labial gland (LG) are of extraordinary complexity, involving enzymes of fatty acid and isoprenoid biosynthesis, which jointly produce more than 50 compounds. We employed a differential transcriptomic approach to identify candidate genes involved in MP biosynthesis by sequencing Bombus terrestris LG and fat body (FB) transcriptomes. We identified 12 454 abundantly expressed gene products (reads per kilobase of exon model per million mapped reads value > 1) that had significant hits in the GenBank nonredundant database. Of these, 876 were upregulated in the LG (> 4-fold difference). We identified more than 140 candidate genes potentially involved in MP biosynthesis, including esterases, fatty acid reductases, lipases, enzymes involved in limited fatty acid chain shortening, neuropeptide receptors and enzymes involved in biosynthesis of triacylglycerols, isoprenoids and fatty acids. For selected candidates, we confirmed their abundant expression in LG using quantitative real-time reverse transcription-PCR (qRT-PCR). Our study shows that the Bombus terrestris LG transcriptome reflects both fatty acid and isoprenoid MP biosynthetic processes and identifies rational gene targets for future studies to disentangle the molecular basis of MP biosynthesis. Additionally, LG and FB transcriptomes enrich the available transcriptomic resources for Bombus terrestris. PMID:26945888

    An acoustic model suitable for the characterization of tuning slots of labial organ pipes is presented in this paper. Since the tuning slot arrangement is similar (but not identical) to that of toneholes in woodwind instruments, the adaptability of the well-established tonehole model for the specific problem is examined. A numerical model utilizing the finite element (FE) and perfectly matched layer techniques is set up for the simulation of tuning slots with design parameters varying over a wide range. Analytical tonehole models and the proposed numerical tuning slot model are both combined with analytical one-dimensional waveguide models to predict the acoustic behavior of tuning slot pipes. Comparison to measurements carried out on experimental pipes proves that the hybrid waveguide/FE model can predict the most important properties of the tuning slot pipe with good accuracy. The finite element method (FEM) also overcomes the limitations of traditional tonehole models relying on the equivalent T-circuit approximation. By means of the FE model the eigenfrequency-structure and its impact on the character of the sound can be foretold in the design phase, by which a more efficient scaling of tuning slot pipes can be achieved.

    Caenorhabditis elegans contains a set of six cluster-type homeobox (Hox) genes that are required during larval development. Some of them, but unlike in flies not all of them, are also required during embryogenesis. It has been suggested that the control of the embryonic expression of the worm Hox genes might differ from that of other species by being regulated in a lineal rather than a regional mode. Here, we present a trans-species analysis of the cis-regulatory region of ceh-13, the worm ortholog of the Drosophila labial and the vertebrate Hox1 genes, and find that the molecular mechanisms that regulate its expression may be similar to what has been found in species that follow a regulative, non-cell-autonomous mode of development. We have identified two enhancer fragments that are involved in different aspects of the embryonic ceh-13 expression pattern. We show that important features of comma-stage expression depend on an autoregulatory input that requires ceh-13 and ceh-20 functions. Our data show that the molecular nature of Hox1 class gene autoregulation has been conserved between worms, flies, and vertebrates. The second regulatory sequence is sufficient to drive correct early embryonic expression of ceh-13. Interestingly, this enhancer fragment acts as a response element of the Wnt/WG signaling pathway in Drosophila embryos. PMID:11820809

  16. Developmental analysis reveals labial and subradular ganglia and the primary framework of the nervous system in nudibranch gastropods.

    Previous ultrastructural observations on late stage larvae of dorid nudibranchs (Gastropoda, Opisthobranchia) revealed two pairs of ganglia within the base of the foot that do not have obvious counterparts in existing descriptions of other gastropod larvae [Chia and Koss (1989). Cell Tiss. Res. 256:17-26.] One of these ganglionic pairs has been implicated in the initiation of settlement preceding metamorphosis [Arkett et al. (1989). Biol. Bull. 176:155-160.] By examining neurogenesis in sequential larval stages, I have found that the pattern of connectives and commissures associated with these enigmatic ganglia is comparable to patterns found in less consolidated adult nervous systems of chitons, monoplacophorans, and archaeogastropods. These comparative data suggest that the two pairs of ganglia in dorid nudibranch larvae are homologues of labial and subradular ganglia. The labial ganglia become incorporated into the cerebral ganglia at metamorphosis. In an attempt to integrate anatomical and developmental observations with behavioral and neurophysiological results, I suggest that receptor cells of the larval labial ganglia may become postmetamorphic primary mechanoreceptors of the oral tube, which have central cell bodies within the "cerebral" ganglia and which help coordinate feeding. Results of this study also address a larger evolutionary issue by questioning the traditional model of an ancestral molluscan nervous system that consists of four longitudinal nerve cords that arise from separate sites along a circumesophageal nerve ring. This pattern results from secondary connections in nudibranchs and possibly other molluscs. The primary condition of a single axon bundle emerging from each cerebral ganglion is more similar to the developing nervous system in polychaete annelids than what has been recognized previously.

    The insect head is composed of several segments. During embryonic development, the segments fuse to form a rigid head capsule where obvious segmental boundaries are lacking. Hence, the assignment of regions of the insect head to specific segments is hampered, especially with respect to dorsal (vertex) and lateral (gena) parts. We show that upon Tribolium labial (Tc-lab) knock down, the intercalary segment is deleted but not transformed. Furthermore, we find that the intercalary segment contributes to lateral parts of the head cuticle in Tribolium. Based on several additional mutant and RNAi phenotypes that interfere with gnathal segment development, we show that these segments do not contribute to the dorsal head capsule apart from the dorsal ridge. Opposing the classical view but in line with findings in the vinegar fly Drosophila melanogaster and the milkweed bug Oncopeltus fasciatus, we propose a "bend and zipper" model for insect head capsule formation.

    The evolution of signals and reproductive traits involved in the pre-mating recognition has been in focus of abundant research in several model species, such as bumblebees (genus Bombus). However, the most-studied bumblebee reproductive trait, the male cephalic labial gland secretions (CLGS), remains unknown among bumblebee species from South America. In this study, the CLGS of five South American bumblebees of the subgenera Thoracobombus (Bombus excellens and B. atratus) and Cullumanobombus (B. rubicundus, B. hortulanus, and B. melaleucus) were investigated, by comparing the chemical compositions of their secretions to those of closely related European species. The results showed an obvious interspecific differentiation in both subgenera. The interspecific differentiation among the species of the Thoracobombus subgenus involved different compounds present at high contents (main compounds), while those of the Cullumanobombus subgenus shared the same main components. This suggests that among the species of the Cullumanobombus subgenus, the differentiation in minor components could lead to species discrimination. PMID:26460558

    Tinnitus is one of the most common symptoms in an audiologic field. It can be classified as either as subjective or objective; former referring to the sensation heard by both patient and examiner. Pulsatile tinnitus is perceived as sounds that vary in frequency, intensity and duration. The cause of pulsatile tinnitus include high jugular bulb, benign intracranial hypertension, glomus tumors, carotid artery stenosis, vascular lesions of the temporal bone, arteriovenous malformation, aneurysms, and Arnold-Chiari malformation. Vascular tinnitus is most common (7.6%). Recently, the authors experienced one case of the pulsatile tinnitus caused by atherosclerosis and atheroma in superior labial artery & facial artery. After surgery, the symptom had disappeared. We report a unique case regarding the objective tinnitus with the literature review. PMID:24653894

    The present study provides new data concerning the external morphology of the labial segments of 46 species from nine Nepomorpha families using the scanning electron microscope. The labial segments are described in detail and images of their structures are presented for the systematic groups. Subsequent segments of the labium (I, II, III, and IV) are shaped similarly in all investigated taxa but carry individual characters in some (sub-)families. Five morphologically distinct forms of the apical plate and five intercalary sclerites have been identified. Additionally, three types of the articulation on the dorsal side between the third and second segments are interpreted as the new characters. The presence of the midventral condyle on the distal edge of the first segment and the third segment has been reanalyzed. New position of the midventral condyle on the proximal edge of the fourth labial segment has been distinguished in several groups. The new set of characters has been estimated from the plesiomorphic taxa of the Nepoidea (Nepidae and Belostomatidae) and subsequently through the more advanced taxa in the relation to the outgroup (Gerromorpha). The evaluation of these characters has revealed twenty-seven new apomorphies for the labium in the Nepomorpha. PMID:24294137

    Background: The upper labial frenum is a normal anatomic structure with inherent morphological variations. Frenum has variations depending upon the attachment of fibers along with the presence of structural variations. Aim: The aim of this study was to evaluate the prevalence of frenal variations in a diverse ethnic population of Sundernagar, Himachal Pradesh. Materials and Methods: This study was conducted on 500 subjects within age group of 16–40 years (285 females, 215 males). Intraoral examination was done to evaluate the variations in frenum and photographs were taken. Results: In this study, depending upon structural variations, normal frenum was most common followed by frenum with nodule while frenum with appendix was found to be least common. However, no significant difference was found between males and females (P > 0.05) with respect to all frenal attachments. Furthermore, other structural variations were found in the diverse population of Sundernagar, Himachal Pradesh. Conclusion: Upper labial frenum is a small anatomical landmark in the oral cavity found to have diverse morphology. The dentist needs to give due importance for frenum assessment during the oral examination. PMID:27563207

    Brown marmorated stink bug, Halyomorpha halys (Stål), (Hemiptera: Pentatomidae) is an invasive polyphagous agricultural and urban nuisance pest of Asian origin that is becoming widespread in North America and Europe. Despite the economic importance of pentatomid pests worldwide, their feeding behavior is poorly understood. Electronically monitored insect feeding (EMIF) technology is a useful tool in studies of feeding behavior of Hemiptera. Here we examined H. halys feeding behavior using an EMIF system designed for high throughput studies in environmental chambers. Our objectives were to quantify feeding activity by monitoring proboscis contacts with green beans, including labial dabbing and stylet penetration of the beans, which we collectively define as ‘probes’. We examined frequency and duration of ‘probes’ in field-collected H. halys over 48 hours and we determined how environmental conditions could affect diel and seasonal periodicity of ‘probing’ activity. We found differences in ‘probing’ activity between months when the assays were conducted. These differences in activity may have reflected different environmental conditions, and they also coincide with what is known about the phenology of H. halys. While a substantial number of ‘probes’ occurred during scotophase, including some of the longest mean ‘probe’ durations, activity was either lower or similar to ‘probing’ activity levels during photophase on average. We found that temperature had a significant impact on H. halys ‘probing’ behavior and may influence periodicity of activity. Our data suggest that the minimal temperature at which ‘probing’ of H. halys occurs is between 3.5 and 6.1°C (95% CI), and that ‘probing’ does not occur at temperatures above 26.5 to 29.6°C (95% CI). We estimated that the optimal temperature for ‘probing’ is between 16 and 17°C. PMID:25474148

    An aberrant frenum causes gingival recession either due to an interference in the plaque control or due to a muscle pull. It also presents an aesthetic problem and may compromise the orthodontic result in midline diastema cases, thus causing a recurrence after the treatment.

    Objective The development of non-Hodgkin's lymphoma (NHL) confers a high risk of mortality in primary Sjögren's syndrome (pSS) patients, but the sensitivity and specificity of proposed lymphoma predictors are insufficient for practical use. The performance of lymphoid organisation in the form of germinal centre (GC)-like lesions was evaluated in labial salivary gland biopsies taken at pSS diagnosis as a potential lymphoma-predicting biomarker. Methods Labial salivary gland tissue biopsies available from two Swedish pSS research cohorts (n=175) were re-evaluated by light microscopy in a blind study in order to identify GC-like structures as a sign of ectopic lymphoid tissue formation and organisation. A linkage study was performed with the Swedish Cancer Registry for lymphoma identification. The risk of developing NHL in GC-positive patients in comparison with GC-negative patients was evaluated using Kaplan–Meier statistics and log-rank test. Associations between GC-like structures and clinical and/or laboratory disease markers were also determined using χ2 or Fisher's exact tests. Results At diagnosis, 25% of pSS patients had GC-like structures in their salivary glands. Seven of the 175 patients studied (14% GC+ and 0.8% GC−) developed NHL during 1855 patient-years at risk, with a median onset of 7 years following the initial diagnostic salivary gland biopsy. Six of the seven patients had GC-like structures at diagnosis; the remaining patient was GC negative at the time of diagnosis (p=0.001). Conclusions The detection of GC-like structures by light microscopy in pSS diagnostic salivary biopsies is proposed as a highly predictive and easy-to-obtain marker for NHL development. This allows for risk stratification of patients and the possibility to initiate preventive B-cell-directed therapy. PMID:21715359

    Background The cell-cycle inhibitor and tumor suppressor cyclin dependent kinase inhibitor, p16ink4a, is one of the two gene products of the ink4a/ARF (cdkn2a) locus on chromosome 9q21. Up-regulation of p16ink4a has been linked to cellular senescence, and findings from studies on different mammalian tissues suggest that p16ink4a may be a biomarker of organismal versus chronological age. Objective The aim of this study was to examine the immunolocalization pattern of p16ink4a in human labial salivary gland (LSG) tissue, and to analyze whether its expression level in LSGs is a peripheral correlate of cognitive decline in late midlife. Methods The present study was a part of a study of causes and predictors of cognitive decline in middle-aged men in a Danish birth cohort. It is based on data from 181 male participants from the Danish Metropolit birth cohort, born in 1953, who were examined for age-associated alterations in cognition, dental health, and morphological and autonomic innervation characteristics of the LSGs. The participants were allocated to two groups based on the relative change in cognitive performance from young adulthood to late midlife. LSG biopsies were analyzed by qRT-PCR for the expression level of p16ink4a. Immunohistochemistry was performed on formalin-fixed, paraffin-embedded sections of LSGs. Results p16ink4a immunoreactivity was observed in LSG ductal, myoepithelial, and stromal cells, but not in acinar cells. The mean relative expression of p16ink4a in LSGs was higher in the group of participants with decline in cognitive performance. A logistic regression analysis revealed that the relative p16 expression was predictive of the participant’s group assignment. A negative correlation was found between relative p16ink4a expression and the participant’s standardized regression residuals from early adulthood to late midlife cognitive performance scores. Conclusions p16ink4a expression in human LSGs may constitute a potential peripheral

    Recently, we revealed the importance of follicular helper T cells (TFH) in the pathogenesis of primary Sjögren's syndrome (pSS). In the present study, we focused on the site of the inflammation and determined the composition of lymphocyte infiltration in labial salivary gland (LSG) biopsies with special emphasis on TFH and germinal center B cells. We selected tissue blocks obtained from ten patients at the time of disease onset. Detection of cell specific markers was performed with immunohistochemical and immunofluorescence stainings. We evaluated patients' clinical and laboratory features retrospectively and assessed the relation between disease course and early histopathological findings. LSG biopsies were graded based on the extension and arrangement level of periductal inflammatory cell infiltrates. TFH cell markers (CD84, PD-1, and Bcl-6) occurred predominantly in more organized structures with higher focus scores. The coexpression of CD3 and Bcl-6 markers clearly identified TFH cells close to Bcl-6+ B cells with the typical formation of germinal centers. Systemic features were developed later in the disease course only in patients with highly structured infiltrates and the presence of TFH cells. Our observations suggest that the presence of TFH cells in LSGs at the disease onset may predict a more pronounced clinical course of pSS. PMID:25177110

    Buff-tailed bumblebees, Bombus terrestris, use a male sex pheromone for premating communication. Its main component is a sesquiterpene, 2,3-dihydrofarnesol. This paper reports the isolation of a thiolase (acetyl-CoA thiolase, AACT_BT), the first enzyme involved in the biosynthetic pathway leading to formation of isoprenoids in the B. terrestris male sex pheromone. Characterisation of AACT_BT might contribute to a better understanding of pheromonogenesis in the labial gland of B. terrestris males. The protein was purified to apparent homogeneity by column chromatography with subsequent stepwise treatment. AACT_BT showed optimum acetyltransferase activity at pH 7.1 and was strongly inhibited by iodoacetamide. The enzyme migrated as a band with an apparent mass of 42.9 kDa on SDS-PAGE. MS analysis of an AACT_BT tryptic digest revealed high homology to representatives of the thiolase family. AACT_BT has 96 % amino acid sequence identity with the previously reported Bombus impatiens thiolase. PMID:25801592

    We investigated in 15 consecutive patients a possible correlation between expression of CMV or EBV in labial salivary gland (LSG) biopsies performed 100 days after allogeneic BMT and subsequent development of chronic GVHD. Three techniques were performed for the detection of each virus: immunohistochemistry, in situ hybridization and PCR. Eleven patients developed chronic GVHD. Histologic examination detected a moderate lymphoid infiltrate (grade 1 according to Sale's score) in LSG biopsy in only one patient. CMV genes or proteins could not be detected in any patients. Likewise, EBV genome or proteins were not detected by in situ hybridization and immunohistochemistry. However, in three of the 15 patients, EBV DNA was detected by PCR in LSG biopsies. Only one of these three patients developed chronic GVHD. Therefore, at the present time, the presence of a lymphoid infiltrate on lip biopsies performed at day 100 post-BMT does not appear to be sensitive enough for the diagnosis or the prediction of the subsequent development of chronic GVHD. Moreover, the absence of EBV and CMV expression in a day-100 LSG biopsy does not preclude the development of chronic GVHD. PMID:8722363

    Hox complexes are important players in the establishment of the body plan of invertebrates and vertebrates. Sequence comparison demonstrates a remarkable phylogenetic conservation of key structural features of Hox genes. The correlation between the physical order of genes along the chromosomes and their domains of function along the body axis is conserved between arthropods and vertebrates. Ectopic expression experiments suggest that the functions of homeo proteins also are conserved between invertebrates and vertebrates. However, it remains an open question whether vertebrate Hox genes expressed under the control of Drosophila regulatory sequences can substitute the function of Drosophila Hox genes. We have studied this issue with the Drosophila labial (lab) gene and its chicken ortholog gHoxb-1. We fused the entire protein-coding region of gHoxb-1 with previously identified regulatory sequences of lab. This approach places gHoxb-1 into the normal embryonic spatiotemporal context in which lab acts. Ten transgenic lines carrying gHoxb-1 were established and tested for their ability to rescue lab null mutant animals. Eight lines rescued with high efficiency, embryonic lethality, and abnormal head morphogenesis, two defects observed in lab null mutant embryos. The rescue with the gHoxb-1 minigene was close to the efficiency of that obtained with the Drosophila lab minigene. This indicates that gHoxb-1 protein can regulate lab target genes and thereby restore embryonic viability. This is striking, as Lab and gHoxb-1 proteins are divergent except for their homeo domains and a short stretch of amino acids amino-terminal to the homeo domain. Our findings demonstrate a functional conservation of the lab class homeo proteins between insects and vertebrates and support the view that function of Hox genes resides in relatively few conserved motifs and largely in the homeo domain.

    Sixty patients (greater than 16 yrs old) suffering primary or relapse genital herpes simplex viruses (HSV) and relapse labial HSV were appointed for this study. Three or more relapses were experienced per year. Patients (under treatment) were divided into two groups (distribution areas), corresponding to either labial herpes or genital herpes. These groups were sub-divided into 3 groups. The total number of labial or facial HSV patients was 36 (10 in group 1, 12 in group 2, 14 in group 3) and 24 for genital, buttocks, or 'area pudenda' HSV patients (6 in group 1, 8 in group 2, 10 in group 3). The design was a randomized, double- blind study. The setting was hospital and outpatient. The patients diagnosed as having the HVS disease were sent to the dermatology department and were assigned to a group at random. Treatment was begun as follows: During the treatment signs and symptoms were assessed and after the treatment, the relapses were also assessed (biochemical and hematological tests before and after the treatment) and the diagnosis of the HSV type I and II. The statistical evaluation of the results was performed and carried out with the SPSS and BMDP program. The relapses of the herpes infection in the lips and the face were significantly reduced (p less than 0.026) in patients treated with laser He-Ne and laser He-Ne plus Acyclovir. The interim between the relapses also increased significantly (p less than 0.005) in relation with the group treated with Acyclovir. The duration of the herpetic eruptions was clearly reduced in all locations in patients treated with laser He-Ne plus Acyclovir. No differences were noted between patients treated with laser He-Ne only or Acyclovir only. Therefore it is probable that therapeutic synergism took place. In relation with this, laser He-Ne shows the same therapeutic efficacy as Acyclovir taken orally. The association of Acyclovir and laser Ne-Ne could be an alternative method for the treatment of HSV in the face. The number

    Intraoral salivary glands undergo remarkable age-related morphologic changes. This study investigated the expression of a panel of molecular markers known for cellular homeostatic activity, dependent on age and location of the salivary glands. Samples taken from healthy subjects were classified according to age ("young" <45 years, n=51, and "old" ≥60 years, n=45) and location (lip, n=47 and palate, n=49). They were immunohistochemically stained for mammary serine protease inhibitor (maspin), heat shock protein (HSP)70, HSP90, glutathione S-transferase (GST), aquaporine5 (AQP5), and nuclear factor kappa-B (NF-κB) for assessment of their expression in acini and ducts, and in cytoplasmic and nuclear compartments. Results were expressed as the mean percentage of positively stained component per age group, gland location and type of cell and cellular compartment. Statistical analysis was performed by two-way ANOVA and crosstabs. The expression of maspin was lower in the old group in both the palatal and labial glands (acini and ducts, cytoplasm and nuclei) compared to the young group (p<0.05). In both age groups, when compared to labial glands, palatal glands exhibited higher expression of HSP70 (p<0.05) and lower expression of AQP5 (p<0.001) and NF-κB (p=0.018). Collectively, the low expression of factors capable of preserving cellular homeostasis (i.e., maspin and AQP5) vis-à-vis a high expression of factors that are also related to cell survival (i.e., HSPs) that was demonstrated in the old palatal glands may point to their high vulnerability to undergo selective phenotypic changes.

    Background: High frenum attachment is a very common problem in the population. Various conventional techniques are available which has certain disadvantages; in addition to that high frenum also hinders oral hygiene maintenance. This study aims to evaluate patient's response to two different frenectomy technique, and oral hygiene maintenance before and after frenectomy. Materials and Methods: Twenty patients with high labial frenum were randomly selected from the outpatient department. Patients were divided into two groups according to the technique used. Each group contained ten patients. One group was treated by “conventional scalpel technique” and other group by “new paralleling technique”. To evaluate patients response, visual analogue scale for pain and speech were taken at first postoperative day, 1-week and 1-month. In other part of the study the oral hygiene maintenance was evaluated by using plaque and gingival bleeding index at baseline before frenectomy, 1-week and 1-month after frenectomy. Results: Results showed that new paralleling technique for frenectomy causes less postoperative discomfort and also there was significant improvement in the oral hygiene maintenance by the patient after frenectomy. Conclusion: High maxillary frenum causes hindrance in oral hygiene maintenance. Paralleling technique for frenectomy causes less discomfort to the patient during healing phase when compared with the conventional technique. PMID:27041834

    Gummy smile has been an esthetic concern for many patients. This clinical report describes a successful surgical coverage obtained by modified lip repositioning, thus surgically treating the gummy smile. The technique was performed to limit the retraction of elevator muscles (e.g., zygomaticus minor, orbicularis oris, leviator anguli oris and levator labi oris.) The technique is fulfilled by removing two strips of mucosa from maxillary buccal vestibule on both the sides leaving the frenum untouched and creating a partial thickness flap between mucogingival junction and upper lip musculature, and suturing the lip mucosa with mucogingival junction, resulting in a narrow vestibule and restricted muscle pull, thereby reducing gingival display. This technique is different from the conventional surgical lip repositioning as labial frenum is left untouched over here as it helps in maintain Litton the midline for lip repositioning and reduces the morbidity associated with it.

    Developmental disturbances of the tongue (aglossia, macroglossia, microglossia, and ankyloglossia) can adversely affect the development of the surrounding structures including the palate, alveolar process, and teeth. These developmental disturbances impair functions such as mastication, speech, and swallowing. Ankyloglossia is of various types and may be associated with other syndromic features like cleft palate. We report a rare type of non-syndromic ankyloglossia associated with missing of the permanent anterior tooth. PMID:25584061

    Canalicular adenoma (CA) is an uncommon benign neoplasia of salivary glands which is clinically difficult to recognise. Despite having an excellent prognosis, the histological diagnosis and clinical management of this entity can be troublesome. While the main differential diagnosis to consider is basal cell adenoma (BCA), similar histological patterns and multifocality have been observed in adenoid cystic carcinoma (ACC) and polymorphous low-grade adenocarcinoma (PLGA), both locally-aggressive malignancies which require radically different treatment to CA. An emphasis has been placed on the value of immunohistochemistry in avoiding diagnostic and surgical errors. CA is positive for AE1/AE3, CD117 and S-100 protein, and negative for p63, α-SMA, Ki 67 and vimentin. Here we discuss the case of a 61-year-old female with CA in her right upper lip, showing multifocal growth histologically. The differential diagnosis with other adenomas is discussed in addition to the role of immunohistochemical studies that can confirm the clinical and surgical findings. PMID:25550873

    Hymenoptera order includes bees, which have a stinging apparatus at the tail capable of delivering venom to the affected tissues. Myocardial infarction, acute renal failure, Necrotizing fasciitis, fatal infection and hemifacial asymmetry, are some of the unusual reactions reported following hymenoptera stings. This paper reports a case of bee sting in the right floor of the nose that mimicked an odontogenic infection affecting the upper lip, canine space and nasal cavity such as in cases of infection secondary to pulpal or periodontal pathology of the anterior teeth. After a thorough clinical and radiographic examination, odontogenic infection was discarded and the diagnosis of floor of the nose mucosal lysis and lip abscess secondary to a bee sting was made. This case was successfully managed with adequate incision, drainage and antibiotics without any further complication. There are several reports of unusual reactions following hymenoptera stings. However, just a few of them referred to infections of local reactions and none of them related to the anatomic location affected in the patient of the present case. Early diagnosis and treatment prevented infection dissemination and the likelihood of tissue necrosis as in previously reported cases of Necrotizing fasciitis. PMID:19784473

    Superficial mucocele is considered a relatively common, uncomplicated, and truly benign oral lesion, although a systematic review of the literature revealed only 27 well-documented cases. The general dentist frequently is confronted with questions from patients regarding these often recurrent blisters. While trauma is suspected to be the cause, the etiology of these lesions is not understood clearly due to the insufficient number of reported cases; as a result, their optimal management remains in question. Insufficient knowledge of the clinical appearance and histopathologic features of this lesion may generate diagnostic confusion, leading to improper diagnosis and inadequate management. This article presents an atypical case of superficial mucocele and summarizes the findings of all previously reported cases to emphasize the variable clinical features and increase general dentists' knowledge of the clinical spectrum regarding this condition's signs and symptoms.

    Advancing the posterior pharyngeal wall is a classic technique to treat velopharyngeal insufficiency. Injection of autologous fat behind the posterior pharyngeal mucosa according to the Coleman Lipostructure technique is a recent development. The authors report their experience in six cases using this modification. The preoperative work-up was performed by a speech therapist with a physical examination and measurement of the nasal air loss was performed using an aerophonometer. Fat was harvested either on the abdominal wall or on a buttock and then centrifuged. Fat injection was performed using a curved blunt cannula under the mucosa of the lateral and posterior pharyngeal walls. Injecting fat is an autologous graft of fat tissue: after a postoperative period of three months, the volume of fat becomes permanently stable. In five out of the six patients who presented moderate velopharyngeal insufficiency, speech improvement was significant. The single failure was a patient with bilateral cleft lip and palate sequels after previous pharyngoplasty using the Orticochea procedure. Treatment of moderate velopharyngeal insufficiency using fat injection is an efficient method. The advantages are its innocuousness and that scaring of the pharynx is avoided. PMID:17675123

    Aim. The aim of this study is to analyze the etiological factors underlying the presence of maxillary midline diastema in a sample of orthodontic patients. Materials and Methods. One hundred patients who fulfill the inclusion criteria were selected from 1355 patients seeking orthodontic treatment. The pretreatment orthodontic records were analyzed. The width of the maxillary midline diastema was measured clinically with a digital caliper at two levels: the mesioincisal angles of the central incisors and five millimeters from the incisal edge. The two measurements were averaged, and patients with diastema of more than 0.5 millimeter in width were enrolled. Results. Diastema is a multifactorial clinical finding with more than one underlying etiological cause. The interrelationship between the familial pattern of midline diastema and the microdontia, macroglossia, labial frenum, and alveolar cleft conforms was clear. The effect of a mesiodens and the upper lateral incisor whether bilaterally missing, unerupted, or peg shaped was minimal. Conclusion. Etiological factors underlying maxillary midline diastema are interconnected. Using a checklist as a guide during handling maxillary midline diastema is important in the different stages of treatment. PMID:27239374

    2014-01-01

    Frequency modulation is a salient acoustic feature of birdsong. Its control is usually attributed to the activity of syringeal muscles, which affect the tension of the labia responsible for sound production. We use experimental and theoretical tools to test the hypothesis that for birds producing tonal sounds such as domestic canaries (Serinus canaria), frequency modulation is determined by both the syringeal tension and the air sac pressure. For different models, we describe the structure of the isofrequency curves, which are sets of parameters leading to sounds presenting the same fundamental frequencies. We show how their shapes determine the relative roles of syringeal tension and air sac pressure in frequency modulation. Finally, we report experiments that allow us to unveil the features of the isofrequency curves. PMID:24730873

    2013-01-01

    This study examines articulatory lenition of intervocalic stops in Spanish and tests the theories that 1) /b, d, g/ have an intended target for closure equal to that of /p, t, k/ and 2) spirantization of /b, d, g/ is caused by undershoot due to their short duration phrase medially. Consistent with past acoustic studies, subjects produce /b/ with incomplete closure phrase medially and complete closure phrase initially. Additionally, /b/ is shorter than /p/ phrase medially though not initially. For /b/, though not for /p/, there is a correlation between constriction degree and duration, consistent with the theory of dynamical undershoot. The results from the study are accurately modeled with a virtual target for /b/ slightly beyond the point of articulator contact. Such a target results in full closure at long durations (such as found phrase initially) and incomplete closure at shorter durations. Based on this evidence, it is proposed that /b, d, g/ differ from /p, t, k/ in three ways: they are shorter, lack a devoicing gesture, and have a target closer to – but still beyond – the point of articulator contact.

    2014-01-01

    Background: The orofacial musculature plays a pivotal role in maintaining a balance in positioning of the teeth and any imbalance which occurs in this , results in malocclusion. Lingual frenum is a soft tissue structure which tethers the ventral surface of the tongue to the floor of the mouth. Objective: This study was performed to analyze the lingual frenal lengths in skeletal class I, class II and Class III malocclusion and to correlate relationship between both. Materials and Methods: This study comprised of 30 subjects, with 10 in each group and an impression was made with the maximum mouth opening position and the tip of tongue touching the incisive papilla. The length of the lingual frenum was then measured from the casts. The maximum mouth opening position was also determined by measuring the interincisal distance with the maximum mouth opening position. Statistical analysis was done to analyze the relationship between both. Results: The lingual frenum was found to be longest in class III malocclusion, with a statistical significant value of p<0.01. The class II and class I malocclusion did not show much difference. The maximum mouth opening position was also increased in class III malocclusion, followed by class II and class I malocclusion, in a descending order. Conclusion: The lingual frenum exerts erratic forces and a long lingual frenum pushes the mandibular anteriors forwards, resulting in malocclusion. Hence, a relationship between the lingual frenum and malocclusion is essential, so that the erratic forces can be eliminated and excellent results can be achieved, following the correction of malocclusion.

    1992-01-01

    In studying language change, Ohala and Lorentz (1977) observed that when the labial-velar glide [w] occurs adjacent to fricative noise, the resulting complex of acoustic features is most often perceived and pronounced as a labial, rather than a velar consonant. However, contemporary Spanish, as spoken in Mexico and the U.S. Southwest, presents a somewhat different pattern. The current research examined two directional predictions based on Ohala and Lorentz (1977) with reference to the perception and production of Spanish fricatives by Chicano children and adults: A Differential Effect of Context hypothesis (more labial/velar fricative interchanges will occur before rounded, rather than unrounded vowels or glides), and a Labial Predominance hypothesis (before a following rounded vowel or glide, labial fricatives will be favored in labial/velar interchanges). Results of perceptual tests provided support for these acoustically-based predictions, but subjects' productions also showed strong influence from sociolinguistic factors in the opposite direction.

  1. The acoustics of uvulars in Tlingit

    NASA Astrophysics Data System (ADS)

    Denzer-King, Ryan E.

    This paper looks at the acoustics of uvulars in Tlingit, an Athabaskan language spoken in Alaska and Canada. Data from five native speakers was used for acoustic analysis for tokens from five phoneme groups (alveolars, plain velars, labialized velars, plain uvulars, and labialized uvulars). The tokens were analyzed by computing spectral moments of plosive bursts and fricatives, and F2 and F3 values for post-consonantal vowels, which were used to calculate locus equations, a descriptive measure of the relationship between F2 at vowel onset and midpoint. Several trends were observed, including a greater difference between F2 and F 3 after uvulars than after velars, as well as a higher center of gravity (COG) and lower skew and kurtosis for uvulars than for velars. The comparison of plain versus labialized consonants supports the finding of Suh (2008) that labialization lowers mean burst energy, or COG, and additionally found labialization to raise skew and kurtosis.

    2016-01-01

    Objective The aim of this study was to investigate whether labial tooth inclination and alveolar bone loss affect the moment per unit of force (Mt/F) in controlled tipping and consequent stresses on the periodontal ligament (PDL). Methods Three-dimensional models (n = 20) of maxillary central incisors were created with different labial inclinations (5°, 10°, 15°, and 20°) and different amounts of alveolar bone loss (0, 2, 4, and 6 mm). The Mt/F necessary for controlled tipping (Mt/Fcont) and the principal stresses on the PDL were calculated for each model separately in a finite element analysis. Results As labial inclination increased, Mt/Fcont and the length of the moment arm decreased. In contrast, increased alveolar bone loss caused increases in Mt/Fcont and the length of the moment arm. When Mt/F was near Mt/Fcont, increases in Mt/F caused compressive stresses to move from a predominantly labial apical region to a palatal apical position, and tensile stresses in the labial area moved from a cervical position to a mid-root position. Although controlled tipping was applied to the incisors, increases in alveolar bone loss and labial tooth inclination caused increases in maximum compressive and tensile stresses at the root apices. Conclusions Increases in alveolar bone loss and labial tooth inclination caused increases in stresses that might cause root resorption at the root apex, despite the application of controlled tipping to the incisors.

    The preservation of an intact labial plate during tooth extraction is a critical determinant of whether an immediate implant can be placed and is also an important predictor of the esthetic result. The purpose of this clinical report was to present a method for atraumatic tooth extraction by using an air-driven sonic instrument with specially designed inserts. This surgical technique provides the clinician with an efficient method for atraumatic tooth extraction and preservation of an intact labial plate. PMID:23217465

    Objective To assess the labial and lingual alveolar bone thickness in adults with maxillary central incisors of different inclination by cone-beam computed tomography (CBCT). Methods Ninety maxillary central incisors from 45 patients were divided into three groups based on the maxillary central incisors to palatal plane angle; lingual-inclined, normal, and labial-inclined. Reformatted CBCT images were used to measure the labial and lingual alveolar bone thickness (ABT) at intervals corresponding to every 1/10 of the root length. The sum of labial ABT and lingual ABT at the level of the root apex was used to calculate the total ABT (TABT). The number of teeth exhibiting alveolar fenestration and dehiscence in each group was also tallied. One-way analysis of variance and Tukey's honestly significant difference test were applied for statistical analysis. Results The labial ABT and TABT values at the root apex in the lingual-inclined group were significantly lower than in the other groups (p < 0.05). Lingual and labial ABT values were very low at the cervical level in the lingual-inclined and normal groups. There was a higher prevalence of alveolar fenestration in the lingual-inclined group. Conclusions Lingual-inclined maxillary central incisors have less bone support at the level of the root apex and a greater frequency of alveolar bone defects than normal maxillary central incisors. The bone plate at the marginal level is also very thin. PMID:26445719

    Tongue tie, also known as ankyloglossia or ankyloglossia inferior, is a relatively common finding in pediatric surgical outpatient clinics. It occurs as a result of a short, tight, lingual frenum causing tethering of the tongue tip. It is a common oral finding in infants and children, which is often neglected. Although most cases resolve or are asymptomatic, some patients develop articulation problems and other concerns related to poor tongue-tip mobility. In this article, we report on a 5-year old girl with a tongue tie, who underwent frenectomy using monopolar diathermy under local anesthesia without any postoperative complication. PMID:20660983

    Dental specialists are frequently confronted with the task of attempting to determine whether a cause and effect relationship exists between a short or restricting lingual frenum (ankyloglossia or tongue-tie) and a specific oral motor dysfunction. Because there is no standardized definition of what constitutes a condition of tongue-tie, the dental practitioner is often unsure as to the appropriate course of action with a patient with suspected ankyloglossia. This paper describes clinical measures that permit quantifying several anatomic and functional aspects of the tongue. Such baseline analysis provides a more definitive appraisal of lingual function as well as a more objective basis for making pre- and posttreatment comparisons. PMID:3858347

    Hox genes encode evolutionarily conserved transcription factors involved in the specification of segmental identity during embryonic development. This specification of identity is thought to be directed by differential Hox gene action, based on differential spatiotemporal expression patterns, protein sequence differences, interactions with co-factors and regulation of specific downstream genes. During embryonic development of the Drosophila brain, the Hox gene labial is required for the regionalized specification of the tritocerebral neuromere; in the absence of labial, the cells in this brain region do not acquire a neuronal identity and major axonal pathfinding deficits result. We have used genetic rescue experiments to investigate the functional equivalence of the Drosophila Hox gene products in the specification of the tritocerebral neuromere. Using the Gal4-UAS system, we first demonstrate that the labial mutant brain phenotype can be rescued by targeted expression of the Labial protein under the control of CNS-specific labial regulatory elements. We then show that under the control of these CNS-specific regulatory elements, all other Drosophila Hox gene products, except Abdominal-B, are able to efficiently replace Labial in the specification of the tritocerebral neuromere. We also observe a correlation between the rescue efficiency of the Hox proteins and the chromosomal arrangement of their encoding loci. Our results indicate that, despite considerably diverged sequences, most Hox proteins are functionally equivalent in their ability to replace Labial in the specification of neuronal identity. This suggests that in embryonic brain development, differences in Hox gene action rely mainly on cis-acting regulatory elements and not on Hox protein specificity. PMID:11731458

    Abstract A new species of western Atlantic Coryphopterus is described from mesophotic depths off Curaçao, southern Caribbean. Coryphopterus curasub sp. n., is similar to Coryphopterus dicrus in, among other features, having two prominent pigment spots of roughly equal intensity on the pectoral-fin base, the pelvic fins fused to form a disk, and no pelvic frenum. The two species can be differentiated by body depth (shallower in Coryphopterus curasub at origin of dorsal fin and caudal peduncle); differences in the pigmentation on the head, trunk, and basicaudal region; and usually by total number of rays (spinous plus soft) in the second dorsal fin (10–11, usually 11, in Coryphopterus curasub, 10 in Coryphopterus dicrus). Coryphopterus curasub differs from other Coryphopterus species that have a prominent pigment spot on the lower portion of the pectoral-fin base (Coryphopterus punctipectophorus and Coryphopterus venezuelae) in, among other features, lacking a pelvic frenum. Coryphopterus curasub was collected between 70 and 80 m, the deepest depth range known for the genus. Collections of Coryphopterus venezuelae at depths of 65–69 m extend the depth range of that species by approximately 50 m. Mitochondrial cytochrome c oxidase subunit I (COI) data corroborate the recognition of Coryphopterus curasub as a distinct species but do not rigorously resolve its relationships within the genus. A revised key to the western Atlantic species of Coryphopterus is presented. PMID:26257572

    PURPOSE The midline fracture of maxillary complete dentures is a frequently encountered complication. The purpose of this study was to assess the effect of frenulum height on midline strains of maxillary complete dentures. MATERIALS AND METHODS A removable maxillary complete denture was fabricated and duplicated seven times. Four different labial frenulum heights were tested for stresses occurring on the palatal cameo surface. The strains were measured with strain gauges placed on 5 different locations and the stresses were calculated. To mimic occlusal forces bilaterally 100 N of load was applied from the premolar and molar region. RESULTS A statistically significant association between the height of the labial frenulum and the calculated stresses and strains was shown (P<.05) predominantly on the midline and especially on the incisive papilla. The results showed that stress on the anterior midline of the maxillary complete denture increases with a higher labial frenulum. CONCLUSION Within the limitations of this in vitro study, it can be concluded that the stress on the anterior midline of the maxillary complete denture increases with a higher labial frenulum. Surgical or mechanical precautions should be taken to prevent short-term failure of maxillary complete dentures due to stress concentration and low cycle fatigue tendency at the labial frenulum region.

    Anuran larvae, which are otherwise simple in shape, typically have complex keratinized mouthparts (i.e. labial teeth and jaw sheaths) that allow them to graze upon surfaces. The diversity in these structures among species presumably reflects specializations that allow for maximal feeding efficiency on different types of food. However, we lack a general understanding of how these oral structures function during feeding. We used high-speed digital imaging (500 Hz) to observe tadpoles of six species from the anuran family Hylidae grazing on a standardized food-covered substrate. Tadpoles of these species vary in the number of labial tooth rows, belong to two different feeding guilds (benthic and nektonic), and inhabit ponds and streams. We confirmed that the labial teeth in these species serve two functions: anchoring the mouth to the substrate and raking material off of the substrate. In general, tadpoles with a larger maximum gape or those with fewer labial tooth rows opened and closed their mouths slower than tadpoles with smaller gape or more tooth rows. Nektonic feeding tadpoles released each of their tooth rows proportionally earlier in the gape cycle compared with benthic feeding tadpoles. Lastly, we found some support for the idea that deformation of the jaw sheaths during a feeding cycle is predictable based on tadpole feeding guild. Collectively, our data show that anatomical (e.g. number of labial teeth) and ecological features (e.g. feeding guild) of tadpoles significantly influence how tadpoles open and close their mouths during feeding.

    This study is to use cone beam computed tomography (CBCT) to acquire accurate radiographic images for alveolar bone in lower incisors and the change after presurgical orthodontic treatment. Seventeen patients with skeletal Class III malocclusion, ten normal occlusion subjects, and fifteen patients treated with orthodontic treatment and orthognathic surgery were included. CBCT images were obtained. The labial and lingual inclinations of mandibular incisors, the thickness of alveolar bone, the vertical alveolar height and root length were measured. Alveolar bone thickness at the apex in patients with skeletal Class III malocclusion was thinner than normal subjects. The vertical alveolar bone heights at labial and lingual sides in patients with skeletal Class III malocclusion were both reduced compared with normal subjects, especially at the labial side. There were statistically significant correlations between lower incisor inclination and alveolar bone morphology. After orthodontics, the incisors root apex was closer to the lingual side of alveolar bone. The alveolar bone thickness at apex was not statistically changed. The vertical alveolar bone heights at the labial and lingual sides were both significantly reduced especially the lingual side after presurgical orthodontic treatment. The root length was not significantly changed. In conclusion, the alveolar bone thickness at apex is thinner and the vertical alveolar height is reduced at the labial side. Forward movement of lower incisors during presurgical orthodontic treatment can render the lower incisors root apex closer to the lingual side and the vertical alveolar height is reduced.

    By means of single-cell matrix assisted laser desorption/ionization time-of-flight mass spectrometry, we analysed neuropeptide expression in all FXPRLamide/pheromone biosynthesis activating neuropeptide synthesizing neurons of the adult tobacco hawk moth, Manduca sexta. Mass spectra clearly suggest a completely identical processing of the pheromone biosynthesis activating neuropeptide-precursor in the mandibular, maxillary and labial neuromeres of the subesophageal ganglion. Only in the pban-neurons of the labial neuromere, products of two neuropeptide genes, namely the pban-gene and the capa-gene, were detected. Both of these genes expressed, amongst others, sequence-related neuropeptides (extended WFGPRLamides). We speculate that the expression of the two neuropeptide genes is a plesiomorph character typical of moths. A detailed examination of the neuroanatomy and the peptidome of the (two) pban-neurons in the labial neuromere of moths with homologous neurons of different insects indicates a strong conservation of the function of this neuroendocrine system. In other insects, however, the labial neurons either express products of the fxprl-gene or products of the capa-gene. The processing of the respective genes is reduced to extended WFGPRLamides in each case and yields a unique peptidome in the labial cells. Thus, sequence-related messenger molecules are always produced in these cells and it seems that the respective neurons recruited different neuropeptide genes for this motif. PMID:19712058

    A unique example of phenotypic flexibility of the oral apparatus is present in newts (Salamandridae) that seasonally change between an aquatic and a terrestrial habitat. Newts grow flaps of skin between their upper and lower jaws, the labial lobes, to partly close the corners of the mouth when they adopt an aquatic lifestyle during their breeding season. Using hydrodynamic simulations based on μCT-scans and cranial kinematics during prey-capture in the smooth newt (Lissotriton vulgaris), we showed that this phenotypic flexibility is an adaptive solution to improve aquatic feeding performance: both suction distance and suction force increase by approximately 15% due to the labial lobes. As the subsequent freeing of the corners of the mouth by resorption of the labial lobes is assumed beneficial for the terrestrial capture of prey by the tongue, this flexibility of the mouth fine-tunes the process of capturing prey throughout the seasonal switching between water and land.

    This project was designed to collect normative data on the genital anatomy from a sample of nonabused prepubertal girls. A total of 114 girls between the ages of 10 months and 10 years were examined and photographed with a colposcope. After screening for the onset of puberty and the possibility of undetected abuse, 93 subjects remained. Examination techniques included a supine labial separation approach, a supine labial traction method, and a prone knee-chest position. Common genital finding included erythema of the vestibule (56%), periurethral bands (50.6%), labial adhesions (38.9%), lymphoid follicles on the fossa navicularis (33.7%), posterior fourchette midline avascular areas (25.6%), and urethral dilation with labial traction (14.9%). The hymenal orifice opened more frequently during the knee-chest (95.2%) and the labial traction (90.5%) methods than with the supine separation (79.3%) approach. Hymenal findings included mounds (33.8%), projections (33.3%), and "septal remnants"/midline hymenal tags (18.5%). Intravaginal findings of vaginal ridges (90.2%) and rugae (88.7%) were found primarily through the labial traction approach. The cervix was visualized without the use of speculum in 69% of the children during the knee-chest examination. Unusual findings included posterior fourchette friability (4.7%), anterior hymenal clefts (1.2%), and notches of the hymen (6%). One child had an imperforate hymen (1.2%) and 2 (2.5%) had hymenal septa. A vaginal discharge was detected in 2 (2.6%) and a foreign body in 1 (1.3%). Tables that include the vertical and horizontal hymenal orifice diameters by age group and by method are presented. PMID:2388791

    Labiaplasty (defined as the surgical reduction of the labia minora) is the most common procedure under the umbrella of female genital cosmetic surgery with the prevalence increasing over the past 10-15 years. However, the concept of labial hypertrophy holds an arbitrary definition, with no research into labial size undertaken within the pediatric and adolescent populations. Under the tenets of medical ethics there is acceptance of the need to avoid harm and so, for reasons to be outlined, performance of labiaplasty in children and adolescents should be avoided. This Mini-Review does not extend to pathological conditions that affect the labia minora. PMID:26453828

    Ankyloglossia, or tongue-tie, is a congenital condition characterized by a short, thickened, or abnormally tight lingual frenulum. This anomaly can cause a varying degree of reduced tongue mobility and has been associated with functional limitations including breastfeeding difficulties, atypical swallowing habits, speech articulation problems, mechanical problems such as inability to clean the oral cavity, and psychosocial stress. In this article, we report a 50-year-old female patient with tongue-tie having difficulty in speech and maintenance of oral hygiene due to high attachment of lingual frenum. The patient was managed by frenectomy by conventional method (scalpel and blade) under local anesthesia as an outpatient procedure without any complications. She later required speech therapy lessons for improvement of speech. PMID:24785748

    The purpose of this case report is to describe the efficacy of a modified Whale's tail technique to achieve primary closure and thereby aid in regeneration of an interdental osseous defect between maxillary central incisors complicated by an aberrant frenal attachment. A healthy 32-year-old female patient reported with the complaint of spacing between her upper front teeth. Clinical examination revealed an aberrant frenum extending into the interdental papilla in relation to the central incisors. There was a 6 mm periodontal pocket in relation to the mesiopalatal aspect of maxillary left central incisor. Intraoral periapical radiograph showed vertical bone loss in relation to mesial aspect of maxillary left central incisor. A modified Whale's tail flap was employed to access the area. The defect was filled with an alloplastic graft. Six months postoperative review showed complete elimination of the pocket along with radiographic bone fill of the defect. PMID:25810604

Ankyloglossia can results in difficulty during speech and deglutition. This case series presents a novel surgical technique in the management of ankyloglossia in using presuturing technique in which different sets of sutures are given on lingual frenum before severing it. This results in reduced opening of the wound, minimal bleeding, pain and discomfort. Two male patients with severe ankyloglossia had been managed with this technique and after 2 years of follow-up of these cases showed satisfactory protrusive and lateral movement of the tongue with minimal scarring and discomfort.

    Purpose To introduce theoretically-driven acoustic measures of /s/ that reflect aerodynamic and articulatory conditions. The measures were evaluated by assessing whether they revealed expected changes over time and labiality effects, along with possible gender differences suggested by past work. Method Productions of /s/ were extracted from various speaking tasks from typically-speaking adolescents (6 boys; 6 girls). Measures were made of relative spectral energies in low- (550–3000 Hz), mid- (3000–7000 Hz), and high-frequency regions (7000–11025 Hz); the mid-frequency amplitude peak; and temporal changes in these parameters. Spectral moments were also obtained to permit comparison with existing work. Results Spectral balance measures in low–mid and mid–high frequency bands varied over the time course of /s/, capturing the development of sibilance at mid-fricative along with showing some effects of gender and labiality. The mid-frequency spectral peak was significantly higher in non-labial contexts, and in girls. Temporal variation in the mid-frequency peak differentiated ±labial contexts while normalizing over gender. Discussion The measures showed expected patterns, supporting their validity. Comparison of these data with studies of adults suggests some developmental patterns that call for further study. The measures may also serve to differentiate some cases of typical and misarticulated /s/. PMID:23785194

    Geocenamus angelescresti n. sp. (Nematoda: Belonolaimidae) was found in rhizosphere of Pinus ponderosa and Arctostaphylos patula growing along Angeles Crest Highway in the San Gabriel mountains of California. The nematode species is characterized by a round-to-hexagonal labial disc with six bulging sectors, lateral sectors of first labial annule smaller than the submedian sectors, six to eight labial annules, distinct deirids, stylet length (45-57 µm), body length (666-996 µm), lateral field with or without areolation of outer bands on tail, and a rounded, smooth tail terminus. Geocenamus angelescresti n. sp. most closely resembles G. superbus but differs from it by a shorter stylet (45-57 µm vs. 67 µm), shorter body length (666-996 µm vs. 1,200 µm), bulged sectors and smaller diameter of the labial disc (2.3-2.8 µm vs. 4.0 µm, round, smooth), longer female tail (54-68 µm vs. 41 µm), and a narrower tail terminus. An emended description of the genus and a list of valid species are provided. Geocenamus arcticus (Mulvey, 1969) Tarjan 1973 and G. uralensis Baydulova 1983 are proposed as junior synonyms of G. tenuidens Thorne &Malek 1968. An identification key to 12 species of Geocenamus and a compendium of important diagnostic morphological characters used in the identification of species are included. PMID:19262887

    The cutaneous areas perfused by the cutaneous perforators of the facial artery have been well defined. However, the oral mucosal areas perfused by perforators of the facial artery have not been described. We studied 20 hemifaces from 10 cadavers. Perforators between the branching off sites of the labial arteries larger than 0.5 mm were selected and their diameters were measured; the distance between their exit point over the facial artery and the branching-off point from the superior labial artery was also measured. The selected perforators were injected with 1 ml of diluted ink. Both labial arteries were ligated to limit the study to the mucosal perforators from the facial artery. Seventy-four perforators from 20 hemifaces were studied; the mean diameter was 0.58 mm and the mean number per artery was 3.7. The total stained area, a triangle-shaped zone on the cheek, was determined. The more constant perforators larger than 0.5 mm were localized next to the branching-off site of the superior labial artery. With this information, flaps based on the mucosal perforators from the facial artery could be designed. PMID:25218801

    1992-01-01

    One hundred and forty two patients (62 with definite Sjögren's syndrome, 24 with probable Sjögren's syndrome, and 56 in whom Sjögren's syndrome was finally ruled out) were studied. Schirmer's test and rose bengal staining for the diagnosis of keratoconjunctivitis sicca and salivary scintigraphy and a labial biopsy sample for the diagnosis of xerostomaia were studied in all patients. Rose bengal staining showed high specificity (98%) but low sensitivity (55%). All patients with positive rose bengal staining results had associated xerostomia. In the rose bengal staining positive patients, scintigraphy had 100% specificity. A labial biopsy sample showed high sensitivity in the rose bengal staining, salivary scintigraphy positive group, and high specificity in the rose bengal staining positive, salivary scintigraphy negative group. In patients with negative rose bengal staining, salivary scintigraphy showed 96% specificity and 36% sensitivity. A labial biopsy sample had a sensitivity and specificity greater than 90% in rose bengal staining negative patients. Only 29 biopsy samples were needed to achieve a diagnosis of Sjögren's syndrome in 142 patients (20%). Hence the suggested approach may make it unnecessary to take biopsy samples in approximately 80% of patients with suspected Sjögren's syndrome. Using the stepwise approach of first rose bengal staining, then salivary scintigraphy, and eventually a labial biopsy sample in patients with suspected Sjögren's syndrome, the diagnosis is relatively simple.

    After the introduction of the colposcope for the examination of children suspected of being sexually abused in Leeds, a study was undertaken to describe the findings in detail. A total of 109 consecutive prepubertal girls, mean age 70.4 months were assessed including colposcopic genital and anal examination, and peer group review of reports and photographs. Fifty nine children had signs consistent with blunt force penetrating trauma (hymenal transection/major notch, scar, or hymenal attenuation). Transections were encountered most commonly at 6 o'clock (directly posterior). In 46 the hymenal orifice was gaping with thigh abduction only and in 47 the hymenal orifice transverse diameter was greater than 4 mm on labial separation. Overall, physical findings were commonly present and in only two cases were no signs recorded. Non-specific and frequent findings included patterns of labial and introital reddening. Supportive hymenal signs including swelling, rounding of edge, thickening, distortion, and loss of symmetry were common. Labial fusion was present in 20. Urethral dilatation with labial separation was noted in 14. Physical findings including normality are consistent with abuse and even minor anogenital signs as well as negative findings should be documented. Colposcopy and photography are valuable tools in peer review, teaching, and case management. PMID:8554370

    Understanding the cellular and molecular mechanisms that underlie tooth regeneration and renewal has become a topic of great interest1-4, and the mouse incisor provides a model for these processes. This remarkable organ grows continuously throughout the animal's life and generates all the necessary cell types from active pools of adult stem cells housed in the labial (toward the lip) and lingual (toward the tongue) cervical loop (CL) regions. Only the dental stem cells from the labial CL give rise to ameloblasts that generate enamel, the outer covering of teeth, on the labial surface. This asymmetric enamel formation allows abrasion at the incisor tip, and progenitors and stem cells in the proximal incisor ensure that the dental tissues are constantly replenished. The ability to isolate and grow these progenitor or stem cells in vitro allows their expansion and opens doors to numerous experiments not achievable in vivo, such as high throughput testing of potential stem cell regulatory factors. Here, we describe and demonstrate a reliable and consistent method to culture cells from the labial CL of the mouse incisor. PMID:24834972

    1975-04-01

    The complete structure of the anterior sensory nervous system of the small nematode C. elegans has been determined by reconstruction from serial section electronmicrographs. There are 58 neurons in the tip of the head. Fifty-two of these are arranged in sensilla. These include six inner labial sensilla, six outer labial sensilla, four cephalic sensilla and two amphids. Each sensillum consists of ciliated sensory neurons ending in a channel enclosed by two non-neuronal cells, the sheath and socket cells. The amphidial channel opens to the outside as does that of the inner labial sensilla so that these probably contain chemoreceptive neurons. The endings of the other sensilla are embedded in the cuticle and may be mechanoreceptive. The cell bodies of all the neurons lie near the nerve ring and their axons project into the ring or into ventral ganglia. One of the ciliated sensory neurons in each of the six inner labial sensilla makes direct chemical synapses onto a muscle making these sensory-motor neurons. The anatomy of four isogenic animals was compared in detail and found to be largely invariant. The anatomy of juveniles is nearly identical to that of the adult, but males have four additional neuron processes. PMID:1112927

    2015-11-01

    Recently, several studies have argued that infants capitalize on the statistical properties of natural languages to acquire the linguistic structure of their native language, but the kinds of constraints which apply to statistical computations remain largely unknown. Here we explored French-learning infants' perceptual preference for labial-coronal (LC) words over coronal-labial words (CL) words (e.g. preferring bat over tab) to determine whether this phonotactic preference is based on the acquisition of the statistical properties of the input based on a single phonological feature (i.e. place of articulation), multiple features (i.e. place and manner of articulation), or individual consonant pairs. Results from four experiments revealed that infants had a labial-coronal bias for nasal sequences (Experiment 1) and for all plosive sequences (Experiments 2 and 4) but a coronal-labial bias for all fricative sequences (Experiments 3 and 4), independently of the frequencies of individual consonant pairs. These results establish for the first time that constellations of multiple phonological features, defining broad consonant classes, constrain the early acquisition of phonotactic regularities of the native language.

    Patient perceptions of genital esthetics are motivating requests for plastic surgeries that could change sexual sensitivity. There is little information about the sensitivities of labial and introital sites. The aim of this study is to assess the relationship between sexual sensitivity and self-reported sizes of labial and introital sites. Sixty-two healthy, sexually active, adult women (mean age 37.9, range 21-60) with no history of genital or vaginal surgery gave written consent to participate in this study. A modified version of Self-Assessment of Genital Anatomy and Sexual Function (L-SAGASF-F) was used to assess labial and introital size. Site-specific sensation was rated on Likert scales of 1-5. Anatomical locations were compared for ratings. Of 62 responders, 84% (52) described their labia as "average-sized," 11% (7) described their labia minora and 13% (8) their labia majora as "large", and 3% (2) and 5% (3) as "small". Sexual pleasure ratings were "moderate" (median value: 3.0 for external genitalia and vaginal lumen) or "strong" (median value: 4.0 for the interior vagina). Significantly higher rankings related to the vaginal opening (P=0.007). Orgasm intensity for stimulation of the external genitalia progressively increased toward the vaginal opening, from 1.0 to 3.0 (P=0.001); vaginal ratings showed a similar progression, from 2.0 at the external luminal margin to 3.0 in the deep interior (P<0.0001). Orgasm effort scores were intermediate (median: 3.0), uniform throughout the external and internal areas (P=0.626). Ratings for labial and introital sensitivity, regardless of self-reported size, were very similar to those at other genital sites for sexual pleasure. Surgical excision of labial and introital structures could modify sexual sensation. PMID:25683213

    Objective: To discuss possible relationships between class III malocclusion and perioral forces by measuring the pressure from the lips and the tongue of children with class III malocclusion. Methods: Thirty-one children with class III malocclusion were investigated and their perioral forces were measured at rest and during swallowing under natural head position by a custom-made miniperioral force computer measuring system. Results: The resting pressures exerted on the labial side and palatine side of the upper left incisor, as well as the labial side and lingual side of the lower left incisor, were 0 g/cm2, 0 g/cm2, 0.57 g/cm2 and 0.23 g/cm2, respectively. Correspondingly, the swallowing forces were 2.87 g/cm2, 5.97 g/cm2, 4.09 g/cm2 and 7.89 g/cm2, respectively. No statistical difference between muscular pressure and gender existed. During swallowing, the lingual forces were significantly higher than the labial forces (P<0.01), however, at rest there was no significantly different force between these two sides. Compared to the normal occlusion patients, children with class III malocclusion had lower perioral forces. The upper labial resting forces (P<0.01), the lower labial resting forces (P<0.05) and all the swallowing pressures from the lips and the tongue (P<0.01) showed statistical differences between the two different occlusion conditions. Meanwhile, no significant difference was found for the resting pressure from the tongue between class III malocclusion and normal occlusion. Conclusion: Patients with class III malocclusion have lower perioral forces and this muscle hypofunction may be secondary to the spatial relations of the jaws. The findings support the spatial matrix hypothesis. PMID:17542055

    Epithelial stem cells reside in specific niches that regulate their self-renewal and differentiation, and are responsible for the continuous regeneration of tissues such as hair, skin, and gut. Although the regenerative potential of mammalian teeth is limited, mouse incisors grow continuously throughout life and contain stem cells at their proximal ends in the cervical loops. In the labial cervical loop, the epithelial stem cells proliferate and migrate along the labial surface, differentiating into enamel-forming ameloblasts. In contrast, the lingual cervical loop contains fewer proliferating stem cells, and the lingual incisor surface lacks ameloblasts and enamel. Here we have used a combination of mouse mutant analyses, organ culture experiments, and expression studies to identify the key signaling molecules that regulate stem cell proliferation in the rodent incisor stem cell niche, and to elucidate their role in the generation of the intrinsic asymmetry of the incisors. We show that epithelial stem cell proliferation in the cervical loops is controlled by an integrated gene regulatory network consisting of Activin, bone morphogenetic protein (BMP), fibroblast growth factor (FGF), and Follistatin within the incisor stem cell niche. Mesenchymal FGF3 stimulates epithelial stem cell proliferation, and BMP4 represses Fgf3 expression. In turn, Activin, which is strongly expressed in labial mesenchyme, inhibits the repressive effect of BMP4 and restricts Fgf3 expression to labial dental mesenchyme, resulting in increased stem cell proliferation and a large, labial stem cell niche. Follistatin limits the number of lingual stem cells, further contributing to the characteristic asymmetry of mouse incisors, and on the basis of our findings, we suggest a model in which Follistatin antagonizes the activity of Activin. These results show how the spatially restricted and balanced effects of specific components of a signaling network can regulate stem cell proliferation in

    Facial approximation techniques used in forensic anthropology are based on soft-tissue thickness databases. However most of articles deal with adult populations, and very few studies were conducted on minors. This study aims at providing data concerning facial thickness for George reconstruction, preliminary to the 3D facial approximation. Diagnostic cephalometric X-ray films were obtained from 222 healthy Caucasoid children (91 boys and 131 girls), aged between 6 and 18years, treated in a Department of Orthodontics of Northern Italy. After setting the Frankfurt plane horizontal, 14 measurements were taken at the mid-facial landmarks: supraglabella, glabella, nasion, nasale, subnasale, superior labial sulcus, labrale superius, stomion, labrale inferius, inferior labial sulcus, suprapogonion, pogonion, gnathion, menton. Mean and standard deviation of soft-tissues thickness at each point were calculated. A two-way analysis of variance (ANOVA) was performed to test the modifications of facial parameters with age and sex (p<0.01). The results demonstrated that there is an increase in tissue thickness as individuals grow; in most occasions, males showed thicker soft tissues than females of the same age, especially after the adolescent growth spurt. Facial thicknesses at subnasale, superior labial sulcus, labrale superius, labrale inferius, inferior labial sulcus, suprapogonion, pogonion and gnathion significantly modified with age, whereas the same parameters at subnasale, superior labial sulcus, labrale superius, labrale inferius, stomion and suprapogonion were significantly sexually dimorphic. In addition, a database for soft-tissue thicknesses in children aged between 6 and 18years was created, which may be of interest in cases of facial approximation of Italian minors. PMID:27591543

    Aim: To determine the effect of three different tooth preparation techniques had on operator's ability to appropriately and consistently prepare teeth for metal ceramic crowns. Materials and Methods: Ninety maxillary left central incisor typodont teeth were allocated to three equal groups (A, B and C) of thirty and mounted in standard working model one at a time. A freehand approach was used to prepare the teeth in Group A, which acted as a control. Groups B and C were prepared with the assistance of silicon index and suitable depth gauge burs, respectively. A silicon index of unprepared teeth, into which contrasting colored silicon injected to occupy the space created by tooth preparation, was sectioned in the midline. Images of sectioned index were captured with optical microscope attached to a personal computer. A calibrated image analysis software was used to measure the depth of preparation (in millimeters) at five points (labial-cervical, mid-labial, incisal, mid-palatal and palatal cervical) on two occasions. These results were pooled and averaged to give a mean labial, incisal and palatal preparation depths in mm. The data were analyzed by one-way analysis of variance and Scheffe's post-hoc statistical test. Results: The mean depth of labial and incisal preparation for Groups A, B and C was 1.23 and 1.72 mm, 1.45 and 1.96 mm, 1.47 and 1.95 mm, respectively. The difference between the groups’ labial preparation depth was significant as well as the difference between groups’ incisal preparation depth. The mean palatal preparation was 0.46 mm for Group A, 0.54 mm for Group B and 0.59 mm for Group C. Conclusion: Teeth preparation for metal ceramic crowns without any assistance can lead to under-preparation of labial and incisal surface. Clinical Significance: Whenever possible, considerable importance should be given to the use of index or depth gauge burs for preparing teeth for receiving metal ceramic crowns. PMID:26929505

    Background Gingival fibromas and dental pitting are among the diagnostic criteria for tuberous sclerosis complex (TSC). Objective Our goal was to document the oral findings in 58 adult patients with TSC. Results Forty patients (69%) had oral fibromas, appearing mostly on the attached or interdental gingiva. Other oral sites included buccal and labial mucosa, the superior labial frenulum, palate, and tongue. Fifty-six patients (97 %) had multiple dental enamel pits. Limitations This case series comprised predominantly adult females with TSC and lymphangioleiomyomatosis. Conclusions Oral fibromas in TSC are mostly, but not exclusively, gingival. Dental pits are present in nearly all patients. The multiple oral papules in TSC may appear similar to those observed in Cowden syndrome, Birt-Hogg-Dube syndrome, and rarely in multiple endocrine neoplasia type 1. PMID:17239986

    The study compared the effects of torque control spurs on upper incisor retroclination and extrusion with two designs of a twin-block functional appliance in Class II/1 cases. The two designs were also compared with respect to anchorage loss in the lower arch and for patient compliance rates. Consecutively started cases were chosen - 90 patients with a design incorporating a labial bow (CTB group) and 110 with upper incisor 'torquing' spurs (STB group) and used to calculate failure rates. Thirty consecutive patients with satisfactory records from each group were analysed cephalometrically. The STB group experienced substantially less upper incisor retroclination, reduced upper incisor extrusion and slightly more favourable mandibular growth. The labial movement of lower incisors and the patient compliance were not significantly different in the two groups. Overall, 82.5% of patients fully reduced their overjet with 9% failing to reduce the overjet below 6 mm.Fig. 1f PMID:11553075

    The aim of the present study was the retrospective evaluation of the distance of the labial hard and soft tissue margins from the implant shoulder in 24 periodontally compromised sites that were restored by immediate implant restorations. Volumetric analysis was performed 5 years postoperatively using cone beam computed tomography with limited field of view. In all cases, a labial radiopaque plate component was apparent 5 years postoperatively coronal to the implant shoulder (3.1 ± 0.6 mm), supporting the soft tissue margin, which was extending above this level (5.2 ± 1.1 mm). In 12 of the sites, preoperative evaluation showed that this plate was missing at the time of implant placement. PMID:27560669

    SUMMARY The continuously growing mouse incisor serves as a valuable model to study stem cell regulation during organ renewal. Epithelial stem cells are localized in the proximal end of the incisor in the labial cervical loop. Here, we show that the transcription factor Sox2 is a specific marker for these stem cells. Sox2+ cells became restricted to the labial cervical loop during tooth morphogenesis, and they contributed to the renewal of enamel-producing ameloblasts as well as all other epithelial cell lineages of the tooth. The early progeny of Sox2-positive stem cells transiently expressed the Wnt inhibitor Sfrp5. Sox2 expression was regulated by the tooth initiation marker FGF8 and specific miRNAs, suggesting a fine-tuning to maintain homeostasis of the dental epithelium. The identification of Sox2 as a marker for the dental epithelial stem cells will facilitate further studies on their lineage segregation and differentiation during tooth renewal. PMID:22819339

    Histological studies of oral cavity mucosa and salivary glands in subjects with chronic alcoholic intoxication revealed changes at the surface of the tongue and in the glandular tissues. Specific features of chronic alcoholic intoxication include acinar and ductal hyperplasia, reduction of the adipose tissue mass in salivary gland stroma, predominance of T-lymphocytes in hard palate minor salivary glands and B-lymphocytes in the stroma of labial minor salivary gland, the absence of plasma cells in the stroma of hard palate minor salivary glands and labial mucosa. Leukoplakia, dysplasia, and hyperplasia of the basal epithelial layer of oral cavity mucosa are considered to be the signs of long-term (over 12 months) alcohol consumption. PMID:21866840

    Some Class II malocclusions are due, at least in part, to a retruded lower dental arch relative to the mandibular body. The purpose of this study was to determine if a direct anterior force on the lower incisors could lead to bodily movement of these teeth. Twenty-seven patients (9 males, 18 females; mean age: 9.8 years) were treated with a reverse headgear (RHG) in the lower dental arch combined with labial root torque of the lower incisors. An activator was added to disclude the arches. This group was compared with 26 patients (10 males, 16 females; mean age: 9.7 years) treated with an activator combined with conventional posterior extraoral traction on the upper molars. All patients had a second stage of treatment with fixed appliances and Class II elastic wear. At the end of treatment, all patients had a Class I relationship and a normal overjet. Lateral cephalograms were taken before (T1), after the first stage (T2), and at the end of active (T3) treatment. Independent sample t-tests were used to assess the differences between the two groups of patients. In the RHG group, despite the applied root torque, the lower incisors showed anterior crown tipping. Labial root displacement was not observed. At T2, this labial tipping partially relapsed. Furthermore, the use of RHG appeared to decrease bone apposition in the anterior part of the symphysis, leading to a reduction in width. Bodily advancement of the lower incisors was not achieved with the application of labial root torque and anteriorly directed force on the mandibular arch. The width limit of the lower anterior apical base should be respected during orthodontic treatment planning. PMID:19395370

    In several primate groups enamel is reduced or absent from the lingual (tongue) side of the mandibular incisor crowns akin to other placental and marsupial mammalian groups such as rodents, lagomorphs and wombats. Here we investigate the presumed adaptation of crowns with unilateral enamel to the incision of tough foods in cercopithecines, an Old World monkey subfamily, using a simulation approach. We developed and validated a finite element model of the lower central incisor of the rhesus macaque (Macaca mulatta) with labial enamel only to compute three-dimensional displacements and maximum principal stresses on the crown subjected to compressive loads varying in orientation. Moreover, we developed a model of a macaque incisor with enamel present on both labial and lingual aspects, thus resembling the ancestral condition found in the sister taxon, the leaf-eating colobines. The results showed that, concomitant with experimental results, the cercopithecine crown with unilateral enamel bends predominantly towards the inside of the mouth, while displacements decreased when both labial and lingual enamel are present. Importantly, the cercopithecine incisor crown experienced lower maximum principal stress on the lingual side compared to the incisor with enamel on the lingual and labial aspects under non-axial loads directed either towards the inside or outside of the mouth. These findings suggest that cercopithecine mandibular incisors are adapted to a wide range of ingestive behaviours compared to colobines. We conclude that the evolutionary loss of lingual enamel in cercopithecines has conferred a safeguard against crown failure under a loading regime assumed for the ingestion (peeling, scraping) of tough-skinned fruits.

    Dental implants have to be placed with the long axis in different angulations due to the change in bone morphology. The objective of this study was to investigate the different bone remodeling response induced by the tilted dental implants and to assess whether it could lead to bone loss and implant failure. In this study, bone remodeling due to palato-labially inclined dental implants placed in the anterior maxillary incisor region was simulated. CT-based finite element models of a maxillary bone with dental implants were created herein. Five dental implants were placed at [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text], respectively. The remodeling progression was recorded and compared. Model [Formula: see text] (palatal side) shows the highest bone density values, but the inclined implant at [Formula: see text] (labial side) leads to significant bone loss. From a biomechanical perspective, it is speculated that a palatally inclined implant is more likely to enhance the bone density in the maxillary anterior region, but labial inclination of implant could jeopardize its stability.

    The organization of termite societies depends predominantly on intraspecific chemical signals (pheromones) produced by exocrine glands, which induce and modulate individual behavioral responses. Here, the saliva-producing labial glands of termites were investigated with respect to their pheromonal role in communal food exploitation of termite colonies. From these glands, we identified for the first time hydroquinone (1,4-dihydroxybenzene) as a phagostimulating pheromone in the Australian termite species Mastotermes darwiniensis. Hydroquinone is released from the labial glands of termite workers and applied onto the food. It stimulates nestmates to feed at the spot of application and is, thus, employed to mark feeding sites. No synergistic effect with other identified labial gland compounds, such as glucose, inositol, and arbutin, was evident. Significantly, we show that termite species from all over the world, irrespective of taxonomic position and biological traits, produce and employ hydroquinone as phagostimulating signal. The use of the same chemical signal throughout an order is a unique phenomenon, not reported before in animals. Its possible biosynthetic pathway, ecological significance, and evolution are discussed. PMID:11868667

    Background and aims. Anterior esthetic restoration is challenging in pediatric dentistry, due to limited durability and poor retention of the restoration.This study assessed the effect of air abrasion on tensile failure load of composite class III restorations using different preparation techniques. Materials and methods. 100 extracted human anterior primary teeth were divided, based on the preparation methods, into four groups each consisting of 25 subjects : conventional (A), labial surface bevel (B), conventional + air abrasion (C), and labial surface bevel + air abrasion (D). After restoring cavities, tensile failure load of samples was measured in Newton by Universal testing machine at a crosshead speed of 1 mm per minute. The data were analyzed by Kruskal-Wallis and Mann Whitney U tests using SPSS software. Results. There were statistically significant differences between groups A and C (P = 0.003), groups A and B (P & 0.001), groups A and D (P & 0.001), groups B and C (P = 0.028), groups B and D (P = 0.027), and also groups C and D (P& 0.001). Group D demonstrated the highest mean tensile failure load. Conclusion. Labial surface bevel treated by air abrasion showed significantly more retention of composite restoration. PMID:25093052

    Enfleurage, the extraction of elusive floral scents with the help of a lipophilic carrier (grease), is widely used in the perfume industry. Male neotropical orchid bees (Euglossini), which accumulate exogenous fragrances as pheromone analogues, use a similar technique. To collect fragrances, the bees apply large amounts of straight-chain lipids to odoriferous surfaces from their cephalic labial glands, which dissolve the volatiles, and the mixture is then transferred to voluminous hind-leg pockets. Here, we show that males do in fact operate a lipid conveyor belt to accumulate and concentrate their perfume. From the hind-leg pockets of caged male Euglossa viridissima, deuterated derivatives of carrier lipids were consecutively sequestered, shuttled back to the labial glands and reused on consecutive bouts of fragrance collection. Such lipid cycling is instrumental in creating complex perfume bouquets. Furthermore, we found that labial glands of male orchid bees are strikingly similar to those of scent-marking male bumblebees in terms of size, form and structure. This, and a prominent overlap in secretory products, led us to propose that perfume collection evolved from scent-marking in ancestral corbiculate bees. PMID:17848369

    Aim: To investigate the fracture resistance of restored endodontically treated teeth (RETT) with fiber posts, cores, and crowns with limited ferrules. Materials and Methods: Sixty maxillary anterior teeth were endodontically treated and decoronated 2 mm above the cemento-enamel junction, and then divided into 6 groups of 10 teeth each; Group circumferential ferrule (2FR), Group ferrule in the labial, mesial, and palatal region (2FR-LaMPa), Group ferrule in the labial, and palatal region (2FR-LaPa), Group 2FR-Pa and 2FR-La respectively, and Group 0FR (no ferrule). All 60 prepared teeth were then restored with quartz fiber posts, resin composite cores, and metal crowns. The specimens were subjected to load until failure occurred. Data were analyzed using one-way analysis of variance and Tukey's tests (α = 0.05). The mode of failure was determined under a stereoscope. Results: A statistical significant difference was found among groups 2FR-LaMPa, 2FR-Pa, 2FR-LaPa, and 2FR from the group 2FR-La, and from the group 0FR (P < 0.01). The predominant mode of failure was an oblique palatal to labial root fracture for the groups with remaining ferrules. Conclusion: For RETT that have incomplete crown ferrules, the location of the ferrules may affect their fracture resistance. PMID:26069401

    Two new species of Cylicospirura Vevers, 1922 are described from carnivores from southern Africa. Cylicospirura crocutae Junker et Mutafchiev sp. n. from Crocuta crocuta (Erxleben) in Zimbabwe is distinguished from its congeners by combinations of characters, including the presence of four cephalic and four external labial papillae, while internal labial papillae were not distinct, the presence of groups of small accessory teeth between the six large tricuspid teeth, the fifth and the sixth pairs of the caudal papillae being equidistant from the cloaca, and a large ratio of length of the muscular oesophagus to that of the glandular oesophagus. Cylicospirura pardalis Junker et Mutafchiev sp. n. from Panthera pardus (Linnaeus) in the Republic of South Africa is characterized by having tricuspid teeth with large, claw-like, abaxial cusps, four cephalic and six internal labial papillae. Based on the number of caudal papillae and the position of the vulva, the subgenera Gastronodus Singh, 1934 and Skrjabinocercina Matschulsky, 1952 are re-elevated to generic rank. Amended diagnoses are proposed for the genera Cylicospirura, Gastronodus and Skrjabinocercina. Petrowospirura lyncis Matschulsky, 1952 is recognized as valid and, together with P. petrowi Sadykhov, 1957 and P. barusi Arya, 1979, is transferred to Cylicospirura as C. lyncis (Matschulsky, 1952) Junker et Mutafchiev comb. n., C. petrowi (Sadykhov, 1957) Junker et Mutafchiev comb. n. and C. barusi (Arya, 1979) Junker et Mutafchiev comb. n., respectively.

    Recreating a harmonious gingival contour for contiguous missing teeth in the anterior maxilla is challenging. The aim of this study was to evaluate a split pedicle roll envelope technique designed for pontics. Twelve patients presented a labial flat or concave profile at the implant and pontic sites before second-stage surgery. The contour deficiency was compensated with a palatal split pedicle flap with the implant part rolled into the labial envelope and the pontic part covering the denuded ridge. Interim restorations were screwed in to guide tissue remodelling. The labial convex profile (CPF) and facial mucosal level (FML) at the implant and pontic sites, the Jemt papilla index (PIS) in the different restorative environments, and peri-implant bone levels were recorded at baseline and at 1 week, 3 months, and 6 months postoperative. Results showed that the CPF had increased by 1.4mm at the implant site and 1.5mm at the pontic site at 6 months after surgery. PIS had increased by 2 at the implant-tooth/pontic-tooth sites and by 2.6 at the implant-pontic site. FML was coordinated with that of the contralateral teeth. All indices were favourable at 3 months and then remained stable. Within the limitations identified, this combined therapy can be considered as an alternative to achieve aesthetic success when contiguous maxillary anterior teeth are missing. PMID:26058360

    The purpose of this study was to apply cone-beam computed tomography (CBCT) to observe contour changes in human alveolar bone after tooth extraction of the maxillary central incisor and to provide original morphological evidence for aesthetic implant treatment in the maxillary anterior area. Forty patients were recruited into the study. Each patient had two CBCT scans (CBCT I and CBCT II), one taken before and one taken three months after tooth extraction of maxillary central incisor (test tooth T). A fixed anatomic reference point was used to orient the starting axial slice of the two scans. On three CBCT I axial slices, which represented the deep, middle, and shallow layers of the socket, labial and palatal alveolar bone widths of T were measured. The number of sagittal slices from the start point to the pulp centre of T was recorded. On three CBCT II axial slices, the pulp centres of extracted T were oriented according to the number of moved sagittal slices recorded in CBCT I. Labial and palatal alveolar bone widths at the oriented sites were measured. On the CBCT I axial slice which represented the middle layer of the socket, sagittal slices were reconstructed. Relevant distances of T on the sagittal slice were measured, as were the alveolar bone width and tooth length of the opposite central incisor. On the CBCT II axial slice, which represented the middle layer of the socket, relevant distances recorded in CBCT I were transferred on the sagittal slice. The height reduction of alveolar bone on labial and palatal sides was measured, as were the alveolar bone width and tooth length of the opposite central incisor at the oriented site. Intraobserver reliability assessed by intraclass correlation coefficients (ICCs) was high. Paired sample t-tests were performed. The alveolar bone width and tooth length of the opposite central incisor showed no statistical differences (P<0.05). The labial alveolar bone widths of T at the deep, middle, and shallow layers all showed

    Introduction: Laser surgery as an alternative for conventional surgical procedure has gained special attention. Using Carbon Dioxide (CO2) laser has some benefits like less post-operative pain, swelling and infection, decrease in risk of metastasis and edema, and less bleeding providing dry sites for surgery. Case Report: A 12 years old boy with lingual frenum with indication for excision was referred to the laser department of Tehran University of medical sciences dental school.CO2 laser was used with 10600 nm wavelength, 1.5 W output power, 100 Hz frequency and 400 μsec pulse duration in non-contact mode. Results: The result of using CO2 laser was dry and bloodless field during operation, no post operative swelling, no pain or discomfort, with normal healing process. Conclusion: We suggest and stimulate the use of CO2 laser for soft tissue surgery because of elimination of suture, convenient coagulation, time saving, patients’ comfort and easy manipulation.

    Periodontal plastic surgery is the branch of periodontology that is focused mainly on the correction or elimination of mucogingival problems associated with lack of attached gingiva, a shallow vestibule and aberrant frenum. Various mucogingival surgical procedures are used to halt the progression of the gingival recession and to correct poor esthetic appearance. Free gingival autograft is one of the most common techniques used for a gingival recession in areas of inadequate attached gingiva in the mandibular anterior region. Fibrin sealants are human plasma derivatives that mimic the final stages of blood coagulation, forming a fibrin clot. Fibrin Sealants enhances the overall outcome of surgical intervention because of their hemostatic, adhesive, and healing properties. These properties of fibrin sealants may reduce operating time, prevent complications, and enhance the overall outcome of many surgical interventions. Hence, this case report aims to investigate the clinical effectiveness of free gingival graft along with the commercially available fibrin-fibronectin sealing system (Tissucol(®)) in the treatment of Miller's class II gingival recession.

    OBJECTIVES--Interactions between vascular cell adhesion molecule 1 (VCAM-1) and its ligand, the alpha 4/beta 1 integrin, have been shown to be important in a number of cellular events in vitro. To assess the importance of such interactions in the development of lymphocytic infiltration in diseased tissue the distribution of the two ligands has been studied immunohistochemically. METHODS--Cryostat sections of labial tissue from patients with Sjögren's syndrome, normal labial tissues, rheumatoid synovia, and normal tonsils were stained using antibodies to VCAM-1, alpha 4 and beta 1 integrin chains, and markers for T cells, B cells, macrophages, and follicular dendritic reticulum cells (FDRCs), visualised using alkaline phosphatase and fast red. RESULTS--Staining patterns for VCAM-1 and integrin chains in lymphocyte aggregates in synovial and labial tissues were similar. VCAM-1 staining was found on both vascular and ramifying dendritic cells at the centre of large T cell aggregates and in all aggregates where there was a central clustering of B cells. VCAM-1 colocalised with, but also extended beyond, staining for the FDRC marker R4/23. Staining for the alpha 4 and beta 1 integrin chains was more widespread than staining for VCAM-1, with no significant increase in staining at sites of maximum VCAM-1 staining. In tonsils VCAM-1 and R4/23 codistributed in germinal centres, but staining for the alpha 4 and beta 1 integrin chains was chiefly seen in T lymphocyte areas. CONCLUSIONS--VCAM-1 may be more important in determining the distribution of B than T lymphocytes in lymphocytic infiltration of non-lymphoid tissue. Unlike the follicles of lymphoid tissue, ectopic follicle-like structures in non-lymphoid tissues may form by immigration of B cells via VCAM-1+ vessels at the centre of T cell aggregates.

    A prospective randomized clinical study was designed to evaluate the effects of full continuous arch wires, rectangular in cross section, on the axial inclination of lower incisors. The intention of rectangular arch wires is to counteract the labial crown moment usually produced during leveling the curve of Spee with full arch mechanics. Patients were randomly assigned to 2 groups. Group 1 (N = 12) received round arch wires throughout the leveling stage. Group 2 (N = 16) started with flat 0.016 x 0.022 nickel titanium arch wires progressing to 0.016 x 0.022 stainless steel. The preadjusted 0.018 x 0.025 edgewise appliance was used in all cases. Lateral cephalometric radiographs and mandibular study models were taken before treatment and when the curve of Spee was leveled (or in some cases when the overbite was considered clinically acceptable). In group 1, the lower incisor proclined a mean of 6.75 degrees +/- 4.85 degrees (P <.01) and in group 2 it proclined a mean of 6.10 degrees +/- 3.95 degrees (P <.01). However, no significant difference in proclination was detected between the 2 groups. Statistically significant, but low, correlations were demonstrated between change in lower incisor axial inclination and relief of crowding r = 0.45) and change in mandibular arch depth r = 0.54), which was in turn inversely correlated with change in intercanine width r = -0.45). In both groups, the lower incisors proclined with uncontrolled tipping that can probably be attributed to the intrusive force introduced by the arch wire being labial to the center of resistance of the lower incisors. The ability of the rectangular arch wires to control labial proclination following leveling of the curve of Spee, as used in this study, was not supported. PMID:10547511

    It is known from the paleontology studies of eutherian mammals that incisor numbers were reduced during evolution. The evolutionary lost incisors may remain as vestigial structures at embryonic stages. The recapitulation of the incisor patterns among mammalian species will potentially uncover the mechanisms underlying the phenotypic transition of incisors during evolution. Here, we showed that a minute tooth formed in the presumptive groove region of the gerbil upper incisor at the early developmental stages, during which multiple epithelial swellings and Shh transcription domains spatiotemporally appeared in the dental epithelium, suggests the existence of vestigial dental primordia. Interestingly, when we trimmed the surrounding mesenchyme from incisor tooth germs at or before the bud stage prior to ex vivo culture, the explants developed different incisor phenotypes ranging from triplicated incisors, duplicated incisors, to Lagomorpha-like incisors, corresponding to the incisor patterns in the eutherian mammals. These results imply that the phenotypic transition of incisors during evolution, as well as the achievement of ultimate incisors in adults, arose from differential integrations of primordia. However, when the incisor tooth germ was trimmed at the cap stage, a grooved incisor developed similar to the normal condition. Furthermore, the incisor tooth germ developed a small but smooth incisor after the additional removal of the minute tooth and a lateral rudiment. These results suggest that multiple dental primordia integrated before the cap stage, with the labial primordia contributing to the labial face of the functional incisor. The minute tooth that occupied the boundary of the 2 labial primordia might be implicated in the groove formation. This study sheds light on how rudiments incorporate into functional organs and aids the understanding of incisor evolution. PMID:26912224

    Molluscs and especially bivalves are able to accumulate dinoflagelates, diatoms and cyanobacteria toxins, and, being vectors for these toxins, transfer them along food chains. The data obtained from laboratory experiments showed that bivalve molluscs are resistant to cyanobacteria toxins. In this work, we wanted to test if Mytilus galloprovincialis organs react to microcystins and other cyanobacteria compounds by inducing or decreasing its GST activity. Acclimated mussels M. galloprovincialis were exposed to the toxic Microcystis aeruginosa M13 strain. Exposure of mussels to toxins was done in three ways: living Microcystis cells, crude Microcystis extracts and pure toxins. The measurement of soluble and microsomal GST activity in the different mussel organs was done by using the substrates 1-chloro-2,4-dinitrobenzene (CDNB) and 2,4-dichloro-1-nitrobenzene (DCNB). Analysis of the GST activity of the control mussels using CDNB as a substrate showed that cytosolic activity is much more significant than microsomal. Intact M. aeruginosa cells did not induce any significant response from the mussels, showing that these animals are quite resistant to the cyanobacteria if they are intact. On the other hand, cell extracts caused an important effect in the gut, in the gills and in the labial palps, although in different ways. There was an increase in GST activity in the gut and gills of mussels exposed to Microcystis extracts, showing a response of this detoxication pathway, but in the labial palps a severe reduction in GST activity occurred. Pure MC LR+YR induced an increase in GST activity in all organs but the labial palps. The results showed that other substances apart from microcystins may cause stress to mussels and affect detoxication enzymes such as GST. PMID:17675203

    Objective : To obtain objective average measurements of the profile and frontal facial soft tissue to be used as a guide for aesthetic treatment goals. Methods and Materials : This observational study included 110 females and 130 males high school students aged 16-18 years. None of the subjects had any facial deformities. All of them and their parents gave consent to take part in this study. In each case, two standard photographs of profile and frontal views were taken 27 landmarks were digitized on photographs. The mean, standard deviation, and range for a total of 43 facial indices were calculated digitally by computer software. The Student’s t-test was used to compare males and females. Results : The ratio between the lower and middle facial thirds was one to one, but the height of the upper facial third was proportionally smaller than the other two-thirds in both sexes. Boys had greater nasal length, depth, and prominence than girls with statistically significant differences. Both upper and lower lips were more prominent in girls than in boys. All measurements of the chin showed sexual dimorphism characterized by greater chin height and prominence and deeper mentolabial sulcus. Boys had greater facial dimensions than girls. Mouth width, nasal base width, and intercanthal distance were significantly greater in boys. Conclusion : The labial, nasal, and chin areas showed sexual dimorphism in most of the parameters used in this study. Boys had larger faces, greater facial heights, longer nasal, labial, and chin lengths, and greater nasal, labial, and chin prominence. PMID:26464606

    The median neuroendocrine cells of the subesophageal ganglion, important components of the neuroendocrine system of the tobacco hawkmoth, Manduca sexta, have not been well investigated. Therefore, we studied the anatomy of these cells by axonal backfills and characterized their peptide immunoreactivities. Both larvae and adults were examined, and developmental changes in these neuroendocrine cells were followed. Processes of the median neuroendocrine cells project to terminations in the corpora cardiaca via the third and the ventral nerves of this neurohemal organ, but the ventral nerve of the corpus cardiacum is the principal neurohemal surface for this system. Cobalt backfills of the third cardiacal nerves revealed lateral cells in the maxillary neuromere and a ventro-median pair in the labial neuromere. Backfills of the ventral cardiacal nerves revealed two ventro-median pairs of cells in the mandibular neuromere and two ventro-median triplets in the maxillary neuromere. The efferent projections of these cells are contralateral. The anatomy of the system is basically the same in larvae and adults. The three sets of median neuroendocrine cells are PBAN- and FMRFamide-immunoreactive, but only the mandibular and maxillary cells are proctolin-immunoreactive. During metamorphosis, the mandibular and maxillary cells also acquire CCK-like immunoreactivity and the labial cells become SCP- and sulfakinin-immunoreactive. Characteristics of FMRFamide-like immunostaining suggest that the median neuroendocrine cells may contain one or more of the FLRFamides that have been identified in M. sexta. The mandibular and maxillary neuroendocrine cells appear to produce the same set of hormones, and a somewhat different set of hormones is produced by the labial neuroendocrine cells. Two pairs of interneurons immunologically related to the neurosecretory cells are associated with the median maxillary neuroendocrine cells. These cells are PBAN-, FMRFamide-, SCP-, and sulfakinin

    BACKGROUND: An objective method that accurately quantifies the severity of Acute Mountain Sickness (AMS) symptoms is needed to enable more reliable evaluation of altitude acclimatization and testing of potentially beneficial interventions. HYPOTHESIS: Changes in human articulation, as quantified by timed variations in acoustic waveforms of specific spoken words (voice onset time; VOT), are correlated with the severity of AMS. METHODS: Fifteen volunteers were exposed to a simulated altitude of 4300 m (446 mm Hg) in a hypobaric chamber for 48 h. Speech motor control was determined from digitally recorded and analyzed timing patterns of 30 different monosyllabic words characterized as voiced and unvoiced, and as labial, alveolar, or velar. The Environmental Symptoms Questionnaire (ESQ) was used to assess AMS. RESULTS: Significant AMS symptoms occurred after 4 h, peaked at 16 h, and returned toward baseline after 48 h. Labial VOTs were shorter after 4 and 39 h of exposure; velar VOTs were altered only after 4 h; and there were no changes in alveolar VOTs. The duration of vowel sounds was increased after 4 h of exposure and returned to normal thereafter. Only 1 of 15 subjects did not increase vowel time after 4 h of exposure. The 39-h labial (p = 0.009) and velar (p = 0.037) voiced-unvoiced timed separations consonants and the symptoms of AMS were significantly correlated. CONCLUSIONS: Two objective measures of speech production were affected by exposure to 4300 m altitude and correlated with AMS severity. Alterations in speech production may represent an objective measure of AMS and central vulnerability to hypoxia.

    This study evaluated volume stability after alveolar ridge contouring with free connective tissue grafts at implant placement in single-tooth gaps. A total of 52 single-tooth gaps with labial volume deficiencies in the maxilla (incisors, canines, and premolars) were consecutively treated with implants and concomitant free palatal connective tissue grafts in 46 patients between 2006 and 2009. Implants had to be covered with at least 2 mm peri-implant local bone after insertion. At implant placement, a free connective tissue graft from the palate was fixed inside a labial split-thickness flap to form an existing concave buccal alveolar ridge contour due to tissue volume deficiency into a convex shape. Standardized volumetric measurements of the labial alveolar contour using a template were evaluated before connective tissue grafting and at 2 weeks, 1 year, and 5 years after implantprosthetic incorporation. Tissue volume had increased significantly (P < .05) in all six reference points representing the outer alveolar soft tissue contour of the implant before connective tissue grafting to baseline (2 weeks after implant-prosthetic incorporation). Statistically, 50% of the reference points (P > .05) kept their volume from baseline to 1 year after prosthetic incorporation and from baseline to 5 years after prosthetic incorporation, respectively, whereas reference points located within the area of the implant sulcus showed a significant (P < .05) decrease in volume. Clinically, 5 years after prosthetic incorporation the originally concave buccal alveolar contour was still convex in all implants, leading to a continuous favorable anatomical shape and improved esthetic situation. Intraoral radiographs confirmed osseointegration and stable peri-implant parameters with a survival rate of 100% after a follow-up of approximately 5 years. Implant placement with concomitant free connective tissue grafting appears to be an appropriate long-term means to contour preexisting buccal

    Abstract We propose the name Bumba as a new name for Maraca, preoccupied by Maraca Hebard, 1926 (Orthoptera). We describe and illustrate Bumba lennoni, a new theraphosid species from Caxiuanã, Pará, Brazil. This species differs from the other species of the genus in the extremely reduced keel on male palpal organ and in the higher number of labial and maxillary cuspules. Females additionally differ in the spermathecal morphology. As a consequence of the name replacement, three new combinations are established. PMID:25408606

    Mucocele and traumatic neuroma are two lesions related to the traumatic events; however there is only one reported case in which these two entities were perceived simultaneously. The current study reported a 21-year-old man who complained of painless recurrent swelling, accompanied by paresthesia on his left lower labial mucosa. He had a previous history of similar lesion and had been treated with surgery and cauterization last year. The primary clinical impression was a recurrent mucocele. Microscopic surveys displayed a traumatic neuroma in the vicinity of a mucocele which seems to be arising from the previous surgical treatment. PMID:24724117

    A mucocele is a common pathological lesion involving the minor salivary glands. It usually presents as an asymptomatic small superficial swelling over the lower labial mucosa. However, uncommon variants of oral mucoceles sometimes occur. Such lesions may be difficult to diagnose due to their unusual size and atypical clinical presentation. This article describes the case of a deeply embedded large mucocele over the buccal mucosa. Ultrasonography was used to visualize the size and position of the lesion, and aspiration was used to help in the eventual diagnosis. An intraoral approach was used in the complete removal of the lesion. PMID:25574732

    Although the oral cavity and dental arches of the Australian aborigine are large, studies of lingual and labial pressures indicate that the tongue is neither unusually large nor strong. The Australian aborigine's pharyngeal cavity is smaller in height and depth than that of the American; just the opposite is true for the oral cavity. To the extent that environmental factors are important at all, the resting pressure of the lips, not tongue pressure during swallowing, is probably the significant determinant of dental arch dimensions.

  13. Ideal implant positioning in an anterior maxillary extraction socket by creating an apico-palatal guiding slot: a technical note.

    2008-01-01

    In anterior maxillary extraction sockets, immediate implants are usually positioned along the palatal slope of the extraction socket. However, this positioning frequently causes unintentional slipping of dental implant toward thin labial plate, leading to its fracture or perforation. To prevent this, the present authors have created a simple apico-palatal guiding slot in the extraction socket following atraumatic extraction. Guided by this slot, sequential drilling up to implant placement can be easily accomplished while maintaining ideal axial orientation of the dental implant. PMID:18416421

    The Tifinagh alphabet-IRCAM is the official alphabet of the Amazigh language widely used in North Africa [1]. It includes thirty-one basic letter and two letters each composed of a base letter followed by the sign of labialization. Normalized only in 2003 (Unicode) [2], ICRAM-Tifinagh is a young character repertoire. Which needs more work on all levels. In this context we propose a data set for handwritten Tifinagh characters composed of 1376 image; 43 Image For Each character. The dataset can be used to train a Tifinagh character recognition system, or to extract the meaning characteristics of each character. PMID:26217753

    Among 350 inhabitants of two villages, 31 (8.9%) cleaned their teeth using table salt and charcoal applied to their forefinger or a Melastoma brush. As a result, all had distinct forms of abrasion cavity on the labial surfaces of their teeth. All of the above three agents are highly abrasive and injurious to both the hard and soft oral tissues. This dying practice is only popular among a very small number of persons in the older age group, and should be discouraged. PMID:2230960

    Lichen sclerosus is a chronic inflammatory condition affecting the anogenital region that may present in the prepubertal or adolescent patient. Clinical presentations include significant pruritus, labial adhesions, and loss of pigmentation. Treatment includes topical anti-inflammatory agents and long-term follow-up as there is a high risk of recurrence and an increased risk of vulvar cancer in adult women with history of lichen sclerosus. These recommendations are intended for pediatricians, gynecologists, nurse practitioners and others who care for pediatric/adolescent girls in order to facilitate diagnosis and treatment.

    Background: Superficial mucocele presents as small, clear vesicle on noninflamed mucosa. In this study, we report several vesicles on the bucal mucosa of a woman diagnosed as superficial mucocele. Case Presentation: A 48-year old woman presented with multiple vesicles on her labial mucosa, ventral surface of the tongue, floor of the mouth and palate. A mucosal biopsy was taken from the vesicle. Histopathologically, intraepithelial mucocele was diagnosed. The lesion was successfully treated with mouthwash betamethasone. There has been no recurrence for 18 months. Conclusion: In the present study, several mucoceles were seen in the oral mucosa. No similar case was reported previously. PMID:24294477

Oral cysticercosis is a rare entity and represents difficulty in clinical diagnosis. This article reports two cases of oral cysticercosis involving buccal and labial mucosa. Both the cases presented with solitary, nodular swelling that had been clinically diagnosed as a mucocele. Histopathology of excisional biopsy revealed it to be cysticercosis. Single, cystic nodular swelling of oral cavity may be the only evidence of cysticercosis and may present first to dentist. These cases emphasise the role of dentist and thorough histopathological examination in the early diagnosis of disease that can prevent potential systemic complication. PMID:23580668

    A number of minor urological surgical procedures can be readily carried out in children in outpatient clinics with the availability of a good topical local anaesthetic. In boys, the separation of preputial adhesions, frenulotomy, meatoplasty, meatal dilatation following circumcision or meatal surgery, the removal of smegma and excision of penile skin lesions can be performed as outpatient treatment. In girls, hymenal abnormalities, meatal abnormalities and labial adhesions come into consideration for its use. Success is dependent on a good estimation of the mental capacity of the child to undergo a local surgical procedure and correct use of the anaesthetic. PMID:9497593

    The aim of this study was to examine the consonant-vowel co-occurrence patterns predicted by the Frame-Content theory in 16 nine-month-old babies with unrepaired cleft palate (± cleft lip) and 16 age-matched non-cleft babies. Babble from these babies was phonetically transcribed and grouped according to the intrasyllabic predictions of the theory (labial-central, alveolar-front, and velar-back). Both groups demonstrated the three consonant-vowel co-occurrence patterns predicted by the Frame-Content theory. Other patterns not predicted by the Frame-Content theory emerged as strong patterns as well. PMID:21889772

    The cellular location of heparin in Mercenaria mercenaria, the northern quahog clam, was identified histologically by azure II and alcian blue/safranin staining. A survey of various organs indicates that heparin was found in several morphological cell subpopulations of the labial palp, ctenidia, intestine, siphon, and pallium. Cells containing these compounds were restricted to areas proximal to epithelial surfaces and granules were observed in all of the cell types except those of the intestine. The "mast-like" cells that we report here may play a role analogous to that of mammalian mast cells in inflammatory responses, using heparin proteoglycan as a supportive defense molecule.

    Stingless bees of the species Trigona spinipes (Fabricius 1793) use their saliva to lay scent trails communicating the location of profitable food sources. Extracts of the cephalic labial glands of the salivary system (not the mandibular glands, however) contain a large amount (approx. 74%) of octyl octanoate. This ester is also found on the scent-marked substrates at the feeding site. We demonstrate octyl octanoate to be a single compound pheromone which induces full trail following behaviour. The identification of the trail pheromone in this widely distributed bee makes it an ideal organism for studying the mechanism of trail following in a day flying insect. PMID:17251108

    The genus Habronema has four valid species, of which only two are properly known. The present study aimed to describe in detail the morphology of Habronema clarki through optical and scanning electron microscopy analyses. Our results showed that the labial morphology of this parasite is closer to H. muscae than to H. microstoma. Even so, the characteristic pseudolabia and the slightly convex border of the dorsal and ventral lips are sufficient to distinguish these nematodes. Additional morphological data are presented, thus contributing to the knowledge on this little known nematode. In addition, this study provides new locality records for this species. PMID:25054508

The large oral apparatus of the tadpole of Boophis picturatus Glaw, Vences, Andreone, and Vallan, 2001 lacks all keratinized structures and has an elaborately-folded lower labium with five, radially oriented, flattopped ridges. The tadpole of Mantidactylus guttulatus (Boulenger, 1881) lacks all keratinized mouthparts and has three immense papillae where the upper jaw normally occurs. The tadpole of Mantidactylus lugubris (Dumeril, 1853) has an ornate oral apparatus involving greatly hypertrophied derivatives of jaw serrations and unique structures on the lower labium that resemble labial teeth.

    In the correction of dental Class III molar relationship in skeletal Class II patients, uprighting of the mandibular posterior segments without opening the mandible is an important treatment objective. In the case reported herein, a C-tube miniplate fixed to the lower labial symphysis and connected with a nickel-titanium reverse-curved archwire provided effective uprighting of the lower molars, without the need of orthodontic appliances on the mandibular anteriors. Using this approach, an appropriate magnitude of force is exerted on the molars while avoiding any negative effect on the mandibular anteriors. PMID:23173121

    An overview of Kuwaiti Arabic is presented, with very preliminary data from two typically developing brothers (ages 2;4 and 5;2) and a 6-year-old with a severe sensorineural hearing impairment. The siblings show early mastery of many aspects of the complex Arabic phonological system, with universally expected later mastery of coronal fricatives and /r/. The 6-year-old shows patterns typical of children with hearing impairments, e.g. hypernasality, a prevalence of 'visible' segments, particularly labials, and simplified syllable structure. Her accurate use of /l/, /r/, and some gutturals, however, raise questions about the enhanced perceptibility and functionality of these segments in Arabic. PMID:19891521

    The purpose of this letter is to explore some reasons for what appear to be conflicting reports regarding the nature and extent of anticipatory coarticulation, in general, and anticipatory lip rounding, in particular. Analyses of labial electromyographic and kinematic data using a minimal-pair paradigm allowed for the differentiation of consonantal and vocalic effects, supporting a frame versus a feature-spreading model of coarticulation. It is believed that the apparent conflicts of previous studies of anticipatory coarticulation might be resolved if experimental design made more use of contrastive minimal pairs and relied less on assumptions about feature specifications of phones.

    More than half of the proteome from mandibular glands in caterpillars is represented by chemosensory proteins. Based on sequence similarity, these proteins are putative transporters of ligands to gustatory receptors in sensory organs of insects. We sought to determine whether these proteins are inducible by comparing, both qualitatively and quantitatively, the salivary (mandibular and labial) proteomes from caterpillars (Vanessa cardui) reared on different plants and artificial diet containing either bacteria or bacterial cell-walls. We included a treatment where the caterpillars were switched from feeding on artificial diet to plant material at some point in their development. Additionally, we evaluated the degree of overlap between the proteomes in the hemolymph-filled coelom and salivary glands of caterpillars reared on plant material. We found that the quality and quantity of the identified proteins differed clearly between hemolymph-filled coelome, labial and mandibular glands. Our results indicated that even after molting and two-day feeding on a new diet, protein production is affected by the previous food source used by the caterpillar. Candidate proteins involved in chemosensory perception by insects were detected: three chemosensory (CSPs) and two odorant-binding proteins (OBPs). Using the relative amounts of these proteins across tissues and treatments as criteria for their classification, we detected hemolymph- and mandibular gland-specific CSPs and observed that their levels were affected by caterpillar diet. Moreover, we could compare the protein and transcript levels across tissues and treatment for at least one CSP and one OBP. Therefore, we have identified specific isoforms for testing the role of CSPs and OBPs in plant and pathogen recognition. We detected catalase, immune-related protein and serine proteases and their inhibitors in high relative levels in the mandibular glands in comparison to the labial glands. These findings suggest that the

    Abnormal labial frena are capable of retracting gingival margins, creating diastemas, and limiting lip movement. When these frena are present, the traditional frenectomy alone generally is successful. However, when the frenulum is extensive, the possibility of coronal reformation exists. Several procedures have combined the frenectomy with either a lateral pedicle flap, free papilla graft, or free gingival (mucosal) graft taken from the palate. Three case reports demonstrate the continued efficacy of the traditional palatal free gingival graft when the patient has an extensive frenulum or an area of minimal esthetic concern is involved.

    Gingival recession of lower incisors in the young population has become more prevalent in association with the increased uptake of orthodontic treatment. The two main predisposing factors are thin gingival biotype and bone dehiscence caused by labially displaced roots. Management is sometimes challenging, and the achievement of a successful result requires close cooperation between the orthodontist and periodontist. This article proposes a decision tree, which includes both orthodontic and periodontal considerations, to help the clinician in making the correct diagnosis and choosing the most suitable treatment in post-orthodontic gingival recessions.

The treatment protocol involved surgical intervention, followed by sequential traction of the impacted teeth. An interdisciplinary approach to treatment with different mechanical strategies led to the achievement of the desired esthetic, functional, and occlusal treatment goals. PMID:25395776

    Two new blind species of Sinella are described from Guangdong Province, China. Sinella colubra sp. n. possesses minute smooth postlabial chaetae, long mucronal spine, and 4+4(5) lateral mac on Abd. IV, and can be distinguished from two closely related species by the postlabial chaetae and the dorsal macrochaetotaxy. Sinella zhangi sp. n. is also described and can be diagnosed by having minute labial chaeta r and postlabial chaetae X and X4, 5+5 mac on Abd. I, 4+4 central mac on Abd. II, and 4+4 central and 5+5 lateral mac on Abd. IV. PMID:27594797

    Aims: To assess and compare the thickness of gingiva in the anterior maxilla using radiovisiography (RVG) and cone beam computed tomography (CBCT) and its correlation with the thickness of underlying alveolar bone. Settings and Design: This cross-sectional study included 10 male subjects in the age group of 20–45 years. Materials and Methods: After analyzing the width of keratinized gingiva of the maxillary right central incisor, the radiographic assessment was done using a modified technique for RVG and CBCT, to measure the thickness of both the labial gingiva and labial plate of alveolar bone at 4 predetermined locations along the length of the root in each case. Statistical Analysis Used: Statistical analysis was performed using Student's t-test and Pearson's correlation test, with the help of statistical software (SPSS V13). Results: No statistically significant differences were obtained in the measurement made using RVG and CBCT. The results of the present study also failed to reveal any significant correlation between the width of gingiva and the alveolar bone in the maxillary anterior region. Conclusions: Within the limitations of this study, it can be concluded that both CBCT and RVG can be used as valuable tools in the assessment of the soft and hard tissue dimensions. PMID:27143830

    This paper examines unusual eighteenth and nineteenth century dental treatment and its consequences, in a nobleman excavated from beneath St. Nicholas' Church, Sevenoaks, Kent, UK in the early 1990s. This rare archaeological case exhibits erosion of dental enamel on the labial surface of all the anterior dentition. A programme of historical research suggests that this might be attributed to the application of an acid-based dental tincture or the use of an abrasive substance to whiten the teeth. Palliative treatment for the consequence of this application was prescribed by Dr Robert Blake of Dublin. Further, it bears witness to three dental restorations, two of gold and one tin. The two gold (foil) fillings are an occlusal in the upper-right second molar and a cervical on the labial surface of the upper left canine. The tin filling is an occlusal in the upper left second molar. Excavation of the carious tissue appears to have been undertaken using a spoon shaped implement. PMID:11132689
