    The Italian lizard (Podarcis sicula) is the most diffused reptile in Italy, but it is also present in other European countries. This lizard belongs to the Lacertidae family, lives near walls, slants and along the borders of the paths; its diet includes bugs and aracnids. No data are so far available in literature about the three-dimensional morphology of the tongue of Podarcis sicula, therefore the aim of the present paper was to study by scanning electron and light microscopy the three-dimensional characteristics of the dorsal lingual surface and moreover the presence of chemosensory receptors like the taste buds in the oral cavity. Our results demonstrate that the Podarcis sicula tongue is a triangular muscular membranous organ, dorsoventrally flattened and that three different areas can be observed: a bifid apex, a body and a root. No papillae were observed in the apex, characterized by a flattened mucosa and by two deep median pouches. In the body cylindrical papillae with a flat surface are present, aborally gradually substituted by imbricated papillae. Foliate-like papillae were observed in the lateral parts of the tongue body. No sensory structures were showed on the lingual dorsal surface, while they were numerous in the oral cavity, particularly on the gingival epithelium. The light microscopy shows, on the dorsal surface, a stratified pavimentous not keratinized epithelium, conversely keratinized along the ventral surface. Many caliciform cells on the lateral parts of the papillae, deputed to the secretion of mucus, were also observed. Therefore, the results obtained in this paper could give a contribution to the knowledge of the tongue anatomy in a species widely diffused in different European countries and could be of help for clinical purposes in reptiles.

    Here is a rare case of lingual leiomyomatous hamartoma (LLH) with bifid tongue tip and tongue-tie in a patient with non-oral-facial-digital syndrome (OFDS). A 29-year-old male consulted for a painless tumor over the midline of the tongue dorsum measuring 2 × 1.5 cm. The tumor was excised and the tongue-tie was corrected. Diagnosis of LLH was based on histo-pathologic and immuno-histochemical studies. The epidemiologic data and differential diagnosis of LLH, as well as related literature, are discussed. To date, only 14 cases of LLH have been reported in English literature. This may be the first reported case of LLH with bifid tip and ankyloglossia in a non-OFDS patient.

  11. Lingual articulation in songbirds.

    Science.gov (United States)

    Suthers, Roderick A; Rothgerber, John R; Jensen, Kenneth Kragh

    2016-02-01

    Lingual articulation in humans is one of the primary means of vocal tract resonance filtering that produces the characteristic vowel formants of speech. In songbirds, the function of the tongue in song has not been thoroughly examined, although recent research has identified the oropharyngeal-esophageal cavity as a resonance filter that is actively tuned to the frequency of the song. In northern cardinals (Cardinalis cardinalis), the volume of this cavity is inversely proportional to the frequency of the song above 2 kHz. However, cardinal song extends below this range, leaving the question of whether and how the vocal tract is tracking these low frequencies. We investigated the possible role of the tongue in vocal tract filtering using X-ray cineradiography of northern cardinals. Below 2 kHz, there was prominent tongue elevation in which the tip of the tongue was raised until it seemed to touch the palate. These results suggest that tongue elevation lowers the resonance frequency below 2 kHz by reducing the area of the passage from the oral cavity into the beak. This is consistent with a computational model of the songbird vocal tract in which resonance frequencies are actively adjusted by both changing the volume of the oropharyngeal-esophageal cavity and constricting the opening into the beak.

    2003-02-01

    This investigation assessed the effect of phonetics training on lingual awareness in normal adult speakers of English. The study also compared Trained subjects' scores from a study in 2000 by Lohman and Fucci to subjects' posttraining scores in this investigation. Subjects were 36 students (M age=19.7, SD=.7) enrolled in an undergraduate phonetics class. All passed a speech and hearing screening. A pretest-posttest design was used. Subjects received approximately 40 hours of phonetics training over a 10-wk. period. The lingual awareness test required subjects imitate seven syllables and respond to four multiple-choice questions about each syllable. Subjects were aided by a line drawing of the oral cavity. A significant improvement in lingual awareness was found following training. However, scores for only two phonemes (sh and k) improved significantly. No significant difference was found between posttest scores and scores from Lohman and Fucci's Trained group.

    The search for the ideal artificial tooth arrangement that maximizes denture stability, comfort, aesthetics, and function has occupied the dental literature for many years and still continues to do so. Of the many occlusal schemes that have been presented to the dental profession, that of lingualized occlusion has emerged as one of the more popular. The popularity of lingualized occlusion stems from the simplicity and flexibility of the concept and from its wide application to clinical practice (Parr & Ivanhoe, 1996). The registration of a repeatable correct centric jaw relation is not always possible. We don't know whether the patient will use centric relation during normal function. It is therefore useful to provide the patient with some freedom of movement around centric. lingualized occlusion provides freedom in centric. For many dentists the arrangement of artificial denture teeth into balanced occlusion is difficult and time consuming. As a result this task is most often performed by the dental technician. In the South African countryside dental laboratories are often far away. If dentists perform the arrangement of the denture teeth, time and costs can be saved. The mounting of denture teeth in lingualized occlusion is simple and fast. This will motivate dentists to arrange denture teeth themselves, with obvious benefits for both the patient and the dentist. The School of Oral Health Sciences of the University of Stellenbosch teaches this concept to its undergraduate students in order to improve the prosthetic service to the large edentulous population of South Africa.

    Full Text Available AbstractObjectiveSome clinical periodontal health parameters were assessed comparatively in patients using conventional and lingual brackets.Material and methodA trained examiner registered the frequencies of visible plaque (VP, bleeding on probing (BOP, as well as the simplified oral hygiene (OHI-S and modified gingival (MGI indices in 83 subjects from two clinics. The effects of orthodontic treatments on periodontal health were analyzed using logistic regression (α = 0.05.ResultIn the conventional group, the frequency of visible plaque was significantly higher on the buccal surfaces of anterior (OR = 12.5 and maxillary posterior (OR = 3.6 teeth, p < 0.01. BOP in posterior teeth was also more frequent in this group, p < 0.05. The lingual group presented higher frequency of visible plaque on the lingual surfaces of anterior teeth (OR = 4.3; p = 0.0034. The conventional group had significantly higher frequencies of mild gingivitis in the buccal regions of anterior (OR = 9.0 and maxillary posterior (OR = 16.7 teeth, p < 0.05, and anterior papillae (OR = 9.0; p = 0.0003. On the other hand, the lingual group evidenced mild gingivitis more often in the lingual regions of anterior teeth (OR = 54.5, p < 0.01.ConclusionBased on the results of this study, the clinical periodontal health conditions may be considered acceptable for patients using both conventional and lingual brackets.

    Full Text Available Despite increasing demand for lingual orthodontics, the technique is not very popular among the orthodontists in general. Lingual orthodontics differs from the conventional labial technique in all aspects. Lack of comprehensive training in this field is a major obstacle in popularizing this science of invisible orthodontics. At present, short-term courses and part-time degree programs are the means to learn this technique and the demand for more comprehensive lingual orthodontic education is on a rise among orthodontists. Lingual orthodontics as a super specialty discipline with full-time residency program can be a step forward. This will groom orthodontists to acquire the finest skills to finish lingual cases but also help to the science to grow with dedicated research work.

  3. A frequent phenotype for paediatric sleep apnoea: short lingual frenulum

    Directory of Open Access Journals (Sweden)

    Christian Guilleminault

    2016-07-01

    Full Text Available A short lingual frenulum has been associated with difficulties in sucking, swallowing and speech. The oral dysfunction induced by a short lingual frenulum can lead to oral-facial dysmorphosis, which decreases the size of upper airway support. Such progressive change increases the risk of upper airway collapsibility during sleep. Clinical investigation of the oral cavity was conducted as a part of a clinical evaluation of children suspected of having sleep disordered breathing (SDB based on complaints, symptoms and signs. Systematic polysomnographic evaluation followed the clinical examination. A retrospective analysis of 150 successively seen children suspected of having SDB was performed, in addition to a comparison of the findings between children with and without short lingual frenula. Among the children, two groups of obstructive sleep apnoea syndrome (OSAS were found: 1 absence of adenotonsils enlargement and short frenula (n=63; and 2 normal frenula and enlarged adenotonsils (n=87. Children in the first group had significantly more abnormal oral anatomy findings, and a positive family of short frenulum and SDB was documented in at least one direct family member in 60 cases. A short lingual frenulum left untreated at birth is associated with OSAS at later age, and a systematic screening for the syndrome should be conducted when this anatomical abnormality is recognised.

    Full Text Available Kebebe Bekele,1 Desalegn Markos2 1Department of Surgery, School of Medicine, Madda Walabu University, Bale Goba, 2Department of Neonatology Nursing, St. Paul Hospital Millennium Medical College, Addis Ababa, Ethiopia Background: Lingual abscesses have become extremely rare since the discovery of antibiotics, despite the relatively frequent exposure of tongue to bite trauma during mastication and seizures. It is a potentially life-threatening clinical entity. Even though there were some case reports on tongue abscess from overseas, none of them were reported from Africa, particularly from Ethiopia.Case presentation: A 36-year-old male patient with severe, continuous pain and swelling of tongue for 6 weeks was presented to Goba Referral Hospital. The swelling was 2 cm by 1 cm, located on posterior central tongue, and frank pus oozed from the center of the swelling. He had associated dysphagia, odynophagia, and speech difficulty. He had no previous personal and family history of similar illness and tonsillitis. Gram staining revealed the presence of Gram-positive cocci in clusters. Pyogenic lingual abscess was the diagnosis. Treatment included incision and drainage with the administration of systemic antibiotics, which covered both aerobic and anaerobic organisms, and anti-pain drugs. The condition did not relapse in 6 months of follow-up. Conclusion: Lingual abscess should be considered in patients presenting with tongue swelling, dysphagia, odynophagia, and speech difficulty. Since lingual abscess that occurs on the posterior part of the tongue has diagnostic difficulty, professionals in rural setup where diagnostic resources (such as ultrasound and magnetic resonance imaging are scarce should be careful not to misdiagnose it. Incision and drainage with the administration of systemic antibiotics and anti-pain drugs is an effective treatment option for lingual abscess.

    2012-08-01

    An 11-year-old male Belgian shepherd dog was evaluated for a one-week history of progressive lethargy, decreased appetite and excessive panting. On physical examination, a pedunculated mass protruding from the right side of the tongue base was observed. The mass was solid, irregular and multi-lobulated, and it measured approximately 4 × 2 cm. The mass was surgically excised. The histological examination was consistent with a lingual osteoma and the margins were free of neoplastic cells. The dog was euthanased eight months after the diagnosis because of an unrelated problem and no evidence of recurrence at the surgical site was appreciated at that time. To the author's knowledge, this is the first report of a lingual osteoma in a dog, and, therefore, it should be included in the differential diagnosis of masses on the tongue, especially pedunculated masses located at the base of the tongue.

    The purpose of the study was to evaluate the effects of the lingual nerve impairment on phonetic quality of speech by analyzing the main acoustic features of vowel sounds when the normal lingual nerve function was partly distorted by local anesthesia. The study group consisted of 7 men, whose right side lingual nerve was anesthetized with 0.8 mL of Ultracaine D-Suprarenin (Aventis Pharma Deutschland GmpH, Frankfurt am Main, Germany). The speech material analyzed consisted of 8 vowels produced in sentence context by speakers. Every utterance was repeated 10 times with and without local anesthesia. After recording, the speech samples were analyzed with a computerized speech laboratory. In addition, the vowels of 1 man with permanent nerve impairment were studied. The results show that the deprived function of the tongue after lingual nerve impairment had various effects on vowel quality for every subject. The main acoustic determinants of different vowels, the lowest vocal tract resonances, changed in frequency. In addition, the total duration of vowels changed and the vowels had different fundamental frequencies. However, these effects were extremely individual and variable. According to the results of acoustic analysis, the distortion of lingual nerve function has effects on vowel production. Some of these changes were so extensive that they also could be perceptually detectable. Lingual nerve impairment seems to have potential to change speech production.

    2004-07-15

    To evaluate whether cone beam computed tomography can depict the distribution, position, frequency, relative vertical dimension, and the diameter of the lingual foramen and direction of lingual bone canal. Cone beam computed tomography of mandible was performed on 25 males and 25 females with no history of any orthodontic treatments or any other dental surgeries. A statistical comparison was done on the mean values of males and females. In the location and distribution of lingual foramina, median lingual foramen was found in all subjects and lateral lingual foramen in 58%. In the lateral lingual foramen, bilateral type was found in 28% and unilateral type in 30%. In the number of lingual foramina, median lingual foramen had two foramina and lateral lingual foramen had one foramen, mostly. In the relative mean vertical dimension of lingual foramina, median lingual foramen was 0.03 {+-} 0.08, and both lateral lingual foramina was 0.20 {+-} 0.04. The mean diameter of lingual foramina, median lingual foramen was 0.9 mm {+-} 0.28, right lateral lingual foramen was 0.92 mm {+-} 0.23, and left lateral lingual foramen was 0.88 mm {+-} 0.27. The most frequent direction of the lingual bone canals, median lingual bone canal proceeded in anteroinferior direction and lateral lingual bone canal in anterosuperolateral direction. Cone beam computed tomography can be helpful for surgery and implantation on the mandibular area. Radiologist should be aware of this anatomical feature and its possible implications.

After appliance insertion, patients completed a Health-Related Quality of Life questionnaire daily for the first week and again on day 14, in order to assess patients' perception of pain and analgesic consumption. In addition, four areas of dysfunction were assessed: oral dysfunction, eating disturbances, general activity parameters, and oral symptoms. Lingual appliance was associated with more severe pain and analgesic consumption, the greatest oral and general dysfunction, and the most difficult and longest recovery. The Invisalign patients complained of relatively high levels of pain in the first days after insertion; however this group was characterized by the lowest level of oral symptoms and by a similar level of general activity disturbances and oral dysfunction compared to the Buccal appliance. Many Lingual and some Buccal patients did not reach a full recovery from their eating difficulties by the end of the study period. The present study provides information to adult patients and clinicians assisting them in choosing the most appropriate treatment modality in relation to Health-Related Quality of Life parameters.

    There are some differences between the two kinds of foreign language teaching methods .The Audio-lingual Method can help students gain control over grammatical structures as well as develop their oral ability, and the teaching focus is often on forms rather than functions, so students have learned a lot of structures or patterns without knowing how to use them appropriately in real situations. While the aim of the Communicative Approach is to develop student's communicative competence, which includes both the knowledge about the language and the knowledge about how to use the language appropriately in communication situations.

    We present the case of a 15-year-old boy who presented to our emergency department because of a soft lesion growing on the back of his tongue. On examination, a vegetant mass on the posteromidline lingual part of the body of the tongue was noticed: it was not painful, even if the boy reported discomfort because of its size; there was no bleeding or signs of infection. The magnetic resonance imaging showed the lesion as trilobated and capsulated, but was not diriment to define a diagnosis; excisional biopsy was performed under general anesthesia, and the mass was identified as a schwannoma. Schwannoma, or neurilemmoma, is a benign tumor originating from Schwann cells of the nerve sheath surrounding peripheral nerves. It is slow-growing, usually solitary, and encapsulated. Intraoral schwannomas are rare and account for 1% of lesions of the head and neck region. There is no sex predilection. The symptoms depend on size and location of the tumor. Recurrence is rare after complete surgical resection. The present study aimed to retrospectively describe our experience with a case of neurilemmoma of the tongue presenting in childhood, the diagnostic methods used, the surgical decision, and the treatment outcome and to analyze the data and review the literature available on this type of tumor. The etiology, clinical presentation, differential diagnosis, and management are discussed.

    The aim of this study was the description of the lingual and buccal papillae in adult alpaca (Vicugna pacos) by light and scanning electron microscopy (SEM). The tongue consisted of apex, body and root. Four types of lingual papillae (filiform, fungiform, conical and circumvallate) in addition to two types of buccal papillae were observed. The filiform papillae, some with secondary papillae, were distributed on both the corpus and apex of the tongue, with stratified epithelium, and layer of keratin coat were recognized. The short (small) cone papillae had pointed top, while bunoform papillae were wide with smooth apex. The much less numerous circumvallate papillae with pseudopapillae on the each rim of the caudal lingual body were present with weak layer of keratin and intra-epithelial taste buds. The small fungiform papillae were found on the dorsal lingual surface, while the large fungiform papillae were situated on the ventral surface of the tongue, especially, in rostral part and were round in shape with numerous gustatory pores and very thin keratin coat. Pseudopapillae were present on the buccal conical 'bunoform' papillae surface, while 'elongate' buccal papillae surface was rather softly folded with thin coat of keratin. Microridges were observed in the less keratinized parts of each type of papillae. The orientation of either lingual or buccal papillae into the throat side facilitates the emptying of oral cavity from nutrient and swallowing of food. In conclusion, the anatomical features of the alpaca tongue are an adaptation to the feeding habits.

    Dental hygienists are often faced with patients wearing lingual orthodontic therapy, as ultrasonic instrumentation (UI) is crucial for oral health. As the application of external forces can lead to premature bonding failure, the aim of this study was to evaluate the effect of UI on shear bond strength (SBS) and on adhesive remnant index (ARI) of different lingual orthodontic brackets. 200 bovine incisors were divided into 10 groups. Four different lingual (STB, Ormco; TTR, Rocky Mountain Orthodontics; Idea, Leone; 2D, Forestadent) and vestibular control (Victory, 3M) brackets were bonded. UI was performed in half of specimens, whereas the other half did not receive any treatment. All groups were tested with a universal testing machine. SBS and ARI values were recorded. Statistical analysis was performed (significance: P = 0.05). TTR, Idea, and 2D lingual brackets significantly lowered SBS after UI, whereas for other braces no effect was recorded. Appliances with lower mesh area significantly reduced their adhesion capacity after UI. Moreover groups subjected to UI showed higher ARI scores than controls. UI lowered SBS of lingual appliances of small dimensions so particular care should be posed avoiding prolonged instrumentation around bracket base during plaque removal. Moreover, UI influenced also ARI scores. PMID:28904955

    Full Text Available Abstract Wegener's granulomatosis (WG is a multi-system disease, characterised by the triad of necrotising granulomata affecting the upper and lower respiratory tracts, disseminated vasculitis and glomerulonephritis. Oral lesions are associated with up to 50% of cases, although are rare as a presenting feature. The most common oral lesions associated with WG are ulceration and strawberry gingivitis. We review the literature regarding oral manifestations of WG and present a case of lingual infarction, an extremely rare oral lesion associated with WG, in a severe, rapidly progressive and ultimately fatal form of the disease.

    Aim: To determine the relationship between the lingual artery and lingual markers for preoperative evaluation of the lingual artery in patients with obstructive sleep apnoea/hypopnoea syndrome (OSAHS). Methods: A 16-section computed tomographic angiography (CTA) of the lingual artery was performed in 87 inpatient cases with OSAHS, from December 2007 to May 2009. The course of the lingual artery and the anatomic relationship between the lingual artery and the lingual markers were analyzed using CTA imaging. Results: The course of the lingual artery with the tongue in a resting position was similar to that of the Big Dipper constellation (Plough) in the sagittal view of CTA imaging. The first segment of the lingual artery declined approximately 19.27 {+-} 5.24 mm, the middle segment of the lingual artery was forward approximately 19.30 {+-} 6.79 mm, and the ascending segment of the lingual artery rose approximately 52.49 {+-} 10.98 mm. The entry point where the lingual artery entered into the tongue was adjacent to the tip of the greater horn of the hyoid bone. The relationship between the second segment of the lingual artery and the greater horn of the hyoid bone was relatively steady with the tongue in whatever position. The interval between the bilateral greater horn of the hyoid bone equalled that between the bilateral lingual arteries. Conclusions: Recognizing some lingual markers in the patients with OSAHS, such as the greater horn of the hyoid bone, foramen cecum, circumvallate papilla, lingual vein and tongue midline, may facilitate the surgeon's ability to define the course of the lingual artery accurately in the treatment of OSAHS.

    Lingual involvement can occur in a variety of neurological disorders including pyramidal, extrapyramidal and lower motor neuron disorders. It can be seen in the form of tremor, bradykinesia, dystonia, atrophy and weakness of tongue movements and can clinically present as difficulty in swallowing and dysarthria which can be a source of great discomfort to the patient. We describe a patient who presented with isolated lingual involvement and was diagnosed to have Wilsons's disease. This case emphasizes the clinical variability in presentation of Wilson's disease and importance of early clinical diagnosis.

    There are different ways of closing extraction spaces with lingual orthodontics. One is to use loop mechanics and the other is to use sliding mechanics. This case report describes the treatment of closing spaces using sliding mechanics with and without the use of microscrews. Understanding and applying basic biomechanical principles is necessary for lingual orthodontics and the use of miniscrews. The purpose of this article is to demonstrate the effect of orthodontic miniscrews in controlling anchorage and the basic biomechanical considerations in understanding the influence of the anterior teeth.

    Lingual tonsils are lymphatic tissues located at the base of the tongue that may hypertrophy causing difficulty and sometimes inability to ventilate or intubate during anesthesia. Routine airway assessment fails to diagnose lingual tonsil hypertrophy. There is limited experience with use of videolaryngoscopy in cases of lingual tonsil hypertrophy. We present a case of difficult airway due to unanticipated lingual tonsil hypertrophy successfully managed by atypical video laryngoscope positioning. Copyright © 2016 Elsevier Inc.

    A 44-year-old female presented to her general dentist with the chief complaint of a painful mouth sore of 2 weeks duration. Clinical examination revealed an irregularly shaped ulcer of the buccal and lingual attached gingiva of the anterior mandible. A biopsy was performed and microscopic evaluation revealed histoplasmosis. Histoplasmosis, caused by Histoplasma capsulate, is the most common fungal infection in the United States. Oral lesions of histoplasmosis are generally associated with the disseminated form of histoplasmosis and may present as a fungating or ulcerative lesion of the oral mucosa. The histologic findings and differential diagnosis for oral histoplasmosis are discussed.

    In sleep apnea syndrome, surgical treatment is applied in obstructive-type cases and some mixed-type cases. If the obstructive part is in the root of the tongue, forward transfer of the tongue, lingual tonsillectomy and laser midline glossectomy are applied. In this study, we demonstrate the surgical technique of lingual tonsillectomy using an ultrasonic coagulating dissector (SonoSurg) with a blade tip shape developed in our department. We conclude that lingual tonsillectomy using SonoSurg, which we have frequently used, should be the first choice of treatment for snoring and sleep apnea caused by hypertrophy of the lingual tonsils from the viewpoints of effectiveness, prevention of hemorrhage, safety and handling.

    We performed a retrospective study of lingual nerve injury assessment comparing the techniques of current perception threshold testing versus clinical sensory testing. We designed and implemented a cross-sectional study and enrolled a patient sample with lingual nerve injuries presenting for treatment to the principal investigator. The predictor variables were clinical sensory testing modalities (ie, temperature, nocioception, vibration, 2-point discrimination, brush stroke, and von Frey monofilament perception). The primary outcome variable was the electrical current perception thresholds of the tongue dorsum (neurometer measurements at 5, 250, and 2,000 Hz). Comparisons were established with the ipsilateral affected and contralateral unaffected lingual nerve distributions. The associations between the clinical sensory testing and current perception threshold measurements were assessed using correlation coefficients, with the level of statistical significance set at P thresholds at 2,000 Hz and the 2-point discrimination, reaction to brushing, reaction to vibration, and von Frey fiber thresholds, between the electrical stimulation thresholds at 250 Hz to the nociceptive and thermal thresholds, and between the electrical stimulation thresholds at 5 Hz to thermal stimuli. The significant correlations observed in the present study indicate that current perception threshold can be a complementary or alternative tool in the assessment and evaluation of lingual nerve injuries.

    Iatrogenic lingual nerve (LN) injuries are quite common in oral surgery both in maxillo-facial surgery and in oral surgery. LN runs superficially into the lateral mouth floor just beneath the mucous layer and this position enhances damage frequency. This article lists the different aetiologies of iatrogenic LN injuries and it almost focuses on lesions due to surgical treatment of ranulas. In the case report a LN lesion due to oral ranula excision is discussed; the patient experienced anaesthesia and hyperpatia in the corrisponded tongue side. It was treated with a microneurosugical anastomosis of LN, after amputation neuroma excision. The partial and definitive recovery of perception happened in six months and was deemed satisfying with 70% of functionality restored (results compared with the functionality of the contralateral side). An algorithm for diagnosis and therapy indication for iatrogenic injuries to nerves is also proposed. In case of surgical treatment, funcitonal recovery manifests after 4-6 month; a functional recovery of 70% of total nerve function is possible. The variable that most affects nerve functional recovery is surgical treatment timing; it must be performed as soon as possible.

    Full Text Available Lingual thyroid gland is a rare clinical entity. The presence of an ectopic thyroid gland located at the base of the tongue may be presented with symptoms like dysphagia, dysphonia, and upper airway obstruction. We are introducing a case of an 8-year-old girl who had lingual thyroid that presented dysphagia and foreign body sensation in the throat. The diagnostic was reached with clinical examination, thyroid scintigraphy with Tc99m and ultrasound. A laryngoscopy was performed which confirmed a spherical mass at base of tongue. Investigation should include thyroid function tests. In this case we observed subclinical hypothyroidism. There are different types of surgical approaches for the treatment of this condition; however, the treatment with Levothyroxine Sodium allowed the stabilization of TSH levels and clinical improvement of symptoms in a follow-up of 2 years.

    Although mepivacaine has a known biphasic action on the aortic and coronary artery in several animal species, its effects on the lingual and pulmonary artery are not well understood and it is not yet known whether mepivacaine produces vasoconstriction in these vessels. The present study aims to investigate the direct effects of mepivacaine on swine lingual, pulmonary and coronary arterial endothelium-denuded rings. Artery rings were perfused with isotonic 40 mM KCl until a stable constricted plateau was reached. The rings were then perfused with isotonic 40 mM KCl plus a particular concentration of mepivacaine (0.4 μM, 4.0 μM, 40 μM, 0.4 mM and 4.0 mM). The isometric tension strengths in each experiment were normalized to the strength of the isometric tension immediately before mepivacaine perfusion and expressed as a percentage. Mepivacaine at 0.4 to 40 μM did not significantly alter 40 mM KCl-induced contraction in the lingual, pulmonary and coronary arterial rings. In contrast, mepivacaine at 4 mM produced attenuated vasoconstriction in the lingual, pulmonary and coronary arterial compared with isotonic 40 mM KCl. Mepivacaine produced vasoconstriction at lower concentrations, followed by attenuated vasoconstriction at higher concentrations on swine lingual, pulmonary and coronary arterial endothelium-denuded rings. Mepivacaine (4 μM) appeared to increase isotonic 40 mM KCl-induced contraction, followed by attenuated vasoconstriction at 4 mM. Dentists using 3 % mepivacaine should take into consideration that the risk of complications may be increased if more than six mepivacaine cartridges are used in dental treatment or minor surgery, or if over 15 ml of mepivacaine is administered to a patient with cardiovascular complications during general anesthesia for oral maxillofacial surgery.

    Full Text Available The tongue epithelium is one of the most rapidly self-renewing tissues in adult mammals. Multiple stem cell populations are currently believed to exist in tongue epithelia. Keratin 14 (K14 positive cells differentiate into either lingual epithelia or lingual papillae, while ecto-nucleoside triphosphate diphosphohydrolase 2 (NTPDase2 is associated with neural stem cells and astrocyte-like cells ensheathing the migrating neuroblasts. Here, using a transgenic mouse expressing rtTA from the mouse NTPDase2 promoter, we generated an inducible model by treatment with Doxycycline. By immunohistochemical analysis and in situ hybridization, we found exclusive expression of NTPDase2 in lingual epithelia and lingual papillae. Using inducible genetic cell fate mapping, we further showed that the NTPDase2+ cells generated lingual papillae and epithelia in the adult tongue. Finally, building on our previously proposed paradigm of cell migration stream, a model is further described here for lingual epithelia cell genesis. In short, the current results not only extend our understanding of the cell migration stream in lingual epithelia and lingual papillae, but they also support the concept of multiple stem cell populations in lingual epithelia and papillae.

    Full Text Available Abstract Background Opportunistic oral infections can be found in over 80% of HIV + patients, often causing debilitating lesions that also contribute to deterioration in nutritional health. Although appreciation for the role that the microbiota is likely to play in the initiation and/or enhancement of oral infections has grown considerably in recent years, little is known about the impact of HIV infection on host-microbe interactions within the oral cavity. In the current study, we characterize modulations in the bacterial composition of the lingual microbiome in patients with treated and untreated HIV infection. Bacterial species profiles were elucidated by microarray assay and compared between untreated HIV infected patients, HIV infected patients receiving antiretroviral therapy, and healthy HIV negative controls. The relationship between clinical parameters (viral burden and CD4+ T cell depletion and the loss or gain of bacterial species was evaluated in each HIV patient group. Results In untreated HIV infection, elevated viremia was associated with significantly higher proportions of potentially pathogenic Veillonella, Prevotella, Megasphaera, and Campylobacter species in the lingual microbiome than observed in healthy controls. The upsurge in the prevalence of potential pathogens was juxtaposed by diminished representation of commensal Streptococcus and Veillonella species. Colonization of Neisseria flavescens was lower in the lingual microbiome of HIV infected patients receiving antiretroviral therapy than in uninfected controls. Conclusions Our findings provide novel insights into the potential impact of HIV infection and antiretroviral therapy on the community structure of the oral microbiome, and implicate potential mechanisms that may increase the capacity of non-commensal species to gain a stronger foothold.

    As tongue cancer is one of the major malignant cancers in the world, understanding the mechanism of maintenance of lingual epithelial tissue, which is known to be the origin of tongue cancer, is unquestionably important. However, the actual stem cells that are responsible for the long-term maintenance of the lingual epithelium have not been identified. Moreover, a simple and convenient culture method for lingual epithelial stem cells has not yet been established. Recently, we have shown that Bmi1-positive cells, residing at the second or third layer of the epithelial cell layer at the base of the interpapillary pit (IPP), were slow-cycling and could supply keratinized epithelial cells for over one year, indicating that Bmi1-positive cells are long-term lingual epithelial stem cells. In addition, we have developed a novel lingual epithelium organoid culture system using a three-dimensional matrix and growth factors. Here, we discuss current progress in the identification of lingual stem cells and future applications of the lingual culture system for studying the regulatory mechanisms of the lingual epithelium and for regenerative medicine.

    Full Text Available As tongue cancer is one of the major malignant cancers in the world, understanding the mechanism of maintenance of lingual epithelial tissue, which is known to be the origin of tongue cancer, is unquestionably important. However, the actual stem cells that are responsible for the long-term maintenance of the lingual epithelium have not been identified. Moreover, a simple and convenient culture method for lingual epithelial stem cells has not yet been established. Recently, we have shown that Bmi1-positive cells, residing at the second or third layer of the epithelial cell layer at the base of the interpapillary pit (IPP, were slow-cycling and could supply keratinized epithelial cells for over one year, indicating that Bmi1-positive cells are long-term lingual epithelial stem cells. In addition, we have developed a novel lingual epithelium organoid culture system using a three-dimensional matrix and growth factors. Here, we discuss current progress in the identification of lingual stem cells and future applications of the lingual culture system for studying the regulatory mechanisms of the lingual epithelium and for regenerative medicine.

    Surgical manipulation of the sensory and motor nerves of the rat tongue is often employed in studies evaluating the oral cavity functions of mastication and deglutition. A noninvasive, atraumatic approach that will then facilitate sufficient manipulation of these structures is required. In this study, we detail an approach that consistently allows identification of the hypoglossal (motor) and lingual (sensory) nerves of the rat. Six Wistar rats (250-500 g) were anesthetized and dissected either as fresh tissue (N = 3) or following transcardial perfusion with 4% paraformaldehyde (N = 3). Both fixed and non-fixed specimens of the rat head and neck were incised in the right submandibular region. The first animal in each group was used to gain a basic understanding of the regional muscular anatomy with reference to the hypoglossal and lingual nerves. Subsequent animals were used for the development of an efficient and minimally invasive approach to these nerves. The resultant approach begins as an incision through skin and platysma, followed by medial reflection of the digastric muscle. This allows visualization of the hypoglossal nerve in the region of the bifurcation of the common trunk into medial and lateral subdivisions. Next, the lingual nerve dissection is approached by reflection rostrally of the transversus mandibularis muscle and a caudal reflection of the mylohyoid muscle. This dissection reveals the geniohyoid muscle which when separated bluntly using forceps, exposes the lingual nerve. The anatomical approach described and illustrated herein will aid investigators in consistent identification of these two nerves as fundamental methods of their projects.

    Congenital hearing loss still remain an important medical and social problem for the delayed language development. Object of this study is to provide an updated and close estimate of the economic burden involved in pre-lingual hearing loss. Data were provided by the Ministry of Health data bank, the Ministry of Education national data bank, the National Institute of Social Insurance national data bank and the Italian Central Statistics Institute. The information was collected by means of a specially provided Societal Cost Questionnaire (SCQ). Direct medical costs, direct non-medical costs and indirect welfare costs involved in deafness were included in the cost estimate. Was enrolled in the study a sample of subjects with pre-lingual deafness, with a mean bilateral neuro-sensorial hearing impairment equal to 60 dB or more for 500, 1,000 and 2,000 Hz frequency tones in the better ear detected in neonatal age, had prevented speech from developing. The statistical assessment was performed according to an actuarial approach, considering the estimated life expectancy at birth, based on updated population data from census 2001. Based on life expectancy, the lifetime mean cost assessed for a subject affected by profound pre-lingual deafness turned out to be equal to Euro 737,994.76 for a male and Euro 755,404.02 for a female. Unlike other disabling affections, deafness weighs significantly more on the social system than on the health system. As a matter of fact, the direct medical costs, such as audiological diagnosis, hearing aids, etc., only account for 3.8% of the societal cost, whereas education, rehabilitation and welfare costs reach 96.2% of the total. Finally, our results suggest that societal costs can only be reduced by zeroing in on promotion and broadening of effective prevention strategies. The appropriate public health measures (such as the universal newborn hearing screening) set up and implemented in several European and non-European countries proved

    Not having access to one sense profoundly modifies our interactions with the environment, in turn producing changes in brain organization. Deafness and its rehabilitation by cochlear implantation offer a unique model of brain adaptation during sensory deprivation and recovery. Functional imaging allows the study of brain plasticity as a function of the times of deafness and implantation. Even long after the end of the sensitive period for auditory brain physiological maturation, some plasticity may be observed. In this way the mature brain that becomes deaf after language acquisition can adapt to its modified sensory inputs. Oral communication difficulties induced by post-lingual deafness shape cortical reorganization of brain networks already specialized for processing oral language. Left hemisphere language specialization tends to be more preserved than functions of the right hemisphere. We hypothesize that the right hemisphere offers cognitive resources re-purposed to palliate difficulties in left hemisphere speech processing due to sensory and auditory memory degradation. If cochlear implantation is considered, this reorganization during deafness may influence speech understanding outcomes positively or negatively. Understanding brain plasticity during post-lingual deafness should thus inform the development of cognitive rehabilitation, which promotes positive reorganization of the brain networks that process oral language before surgery. This article is part of a Special Issue entitled Human Auditory Neuroimaging.

    Running through the infratemporal fossa is the lingual nerve (i.e. the third branch of the posterior trunk of the mandibular nerve). Due to its location, there are various anatomic structures that might entrap and potentially compress the lingual nerve. These anatomical sites of entrapment are: (a) the partially or completely ossified pterygospinous or pterygoalar ligaments; (b) the large lamina of the lateral plate of the pterygoid process; and (c) the medial fibers of the anterior region of the lateral pterygoid muscle. Due to the connection between these nerve and anatomic structures, a contraction of the lateral pterygoid muscle, for example, might cause a compression of the lingual nerve. Any variations in the course of the lingual nerve can be of clinical significance to surgeons and neurologists because of the significant complications that might occur. To name a few of such complications, lingual nerve entrapment can lead to: (a) numbness, hypoesthesia or even anesthesia of the tongue's mucous glands; (b) anesthesia and loss of taste in the anterior two-thirds of the tongue; (c) anesthesia of the lingual gums; and (d) pain related to speech articulation disorder. Dentists should, therefore, be alert to possible signs of neurovascular compression in regions where the lingual nerve is distributed. PMID:21404967

    Common origin of lingual and facial artery is a relatively frequent anatomic varia-tion. Instead, bilateral lingual-facial trunk has been described only sparsely in the literature. In this report authors describe and analyse a case of bilateral common lingual-facial trunk in the context of its anatomical, clinical and embryological implications. We also describe possible consequences in performance of elective and emergent surgical operations and modification in surgical techniques that should be considered. We believe that surgeons should be suspicious for this variation's existence and keep alternative solutions in their armentarium.

    The incidence of tuberculosis has lately increased in developed countries. The most frequent affectation is the pulmonar one and in the ORL area the laryngeal. The lingual affectation is exceptional. We present a case of a man 39 years old, with bilateral pulmonar, left vocal cord and mobile tongue affectation, negative Mantoux, positive spit culture and presence of acido-alcohol resistent bacillus in lingual and laryngeal biopsies. After antituberculosis treatment during 6 months the laryngeal and lingual lesions disappeared. We have only found two cases published of simultaneous tuberculosis in these three localisations in the last 30 years.

  19. Cross-Lingual Adaptation using Structural Correspondence Learning

    CERN Document Server

    Prettenhofer, Peter

    2010-01-01

    Cross-lingual adaptation, a special case of domain adaptation, refers to the transfer of classification knowledge between two languages. In this article we describe an extension of Structural Correspondence Learning (SCL), a recently proposed algorithm for domain adaptation, for cross-lingual adaptation. The proposed method uses unlabeled documents from both languages, along with a word translation oracle, to induce cross-lingual feature correspondences. From these correspondences a cross-lingual representation is created that enables the transfer of classification knowledge from the source to the target language. The main advantages of this approach over other approaches are its resource efficiency and task specificity. We conduct experiments in the area of cross-language topic and sentiment classification involving English as source language and German, French, and Japanese as target languages. The results show a significant improvement of the proposed method over a machine translation baseline, reducing th...

    The report describes an HIV/AIDS patient seen at a referral center in Mexico City, in whom a mycobacterial infection in the oral mucosa, probably tuberculosis (TB) was identified. The purpose is to describe the clinical and histological findings in an HIV-infected patient, who after being treated successfully for tuberculous lymphangitis 4 years ago, presented with a lingual ulcer as the only suggestive sign of recurrence of mycobacterial infection, probably M. tuberculosis. A 39-year-old man seen in the HIV clinic of the Instituto Nacional de Ciencias Médicas y Nutrición "Salvador Zubirán" in Mexico City since 1991 for HIV infection. In 1999 the patient developed tuberculous lymphangitis; he was managed with a 4-drug regimen for 12 months, with improvement of local and systemic symptoms. In May of 2003, the patient presented a painful superficial lingual ulcer, 0.7 cm in diameter, well circumscribed, crateriform with slightly elevated, irregular and indurated borders, of 4 months duration. The histopathological examination showed chronic granulomatous inflammation with giant multinucleated cells, suggestive of mycobacterial infection, and recurrence of TB was considered. Rifampin, isoniazide, pyrazinamide, ethambutol and streptomycin were administered. The lingual lesion improved with partial healing at the first week and total remission at 45 days after the beginning of the antituberculous treatment. In June, 2003, the patient began highly active antiretroviral therapy (HAART) that included two NRTIs and one NNRTI. At 7 months of follow-up, the patient remains free of lingual lesions. The particularity of the present case is that the lingual ulcer was the only sign of infection by mycobacteria, suggestive of TB, in an HIV/AIDS patient that probably represented a recurrence of a previous episode.

  1. Tempat Kedudukan Rest Lingual dalam Pembuatan Gigi Tiruan Sebagian Lepas Kerangka Logam Lingual Rest Seat in Removable Partial Denture

    Directory of Open Access Journals (Sweden)

    Armida Sofyanis

    2015-09-01

    Full Text Available In certain cases, lingual rest is needed to provide better retention for RPD. Lingual rest is a cingulum rest placed on the lower jaw in RPD design. It is used as an indirect retainer. To make the rest fit best, a good rest seat should be prepared in the cingulum. The outline form of the lingual rest is a half moon shaped with a smooth curve from one marginal ridge to the other, crossing the center of the tooth. The rest seat itself should be V shaped, and the depth is 1 - 1 1/2mm. In this situation, one of four options should be considered i.e.: fabricate a cast veneer crown, or a three quarter crown to place a lingual pin-lay, or put a small amalgam restoration in the base of the preparation when the dentin has been touched.  

  2. Transient isolated lingual nerve neuropraxia associated with general anaesthesia and laryngeal mask use: two case reports and a review of the literature.

    LENUS (Irish Health Repository)

    Foley, E

    2012-02-01

    BACKGROUND: Transient, isolated lingual nerve neuropraxia is a rare complication following general anaesthesia. Reports implicate airway manipulation and we describe two new cases associated with laryngeal mask airway (LMA) and review the related English language literature. RESULTS: Unilateral numbness and loss of taste on the anterior tongue were the characteristic symptoms. Collation of literature data (median and range) with that from the new cases showed: patient age was 38 (20-61) years and female to male ratio was 1.2:1. Surgery time was 62.5 (20-150) min and symptom duration was 28 (7-120) days. CONCLUSION: Lingual neuropraxias reported have been transient and patients can be advised, despite disturbing symptoms, that recovery is anticipated in about 1 month. Lingual neuropraxia reports are becoming more frequent, perhaps associated with increasing LMA use. Research is recommended as modification to LMA cuff volume, pressure and\\/or position within the oral cavity might ameliorate the entity.

    Full Text Available Ectopic thyroid gland may be detected at any place between foramen caecaum and normal thyroid localization due to inadequacy of the embryological migration of the thyroid gland. It has a prevalence varying between 1/10.000 and 1/100000 in the community. Usually follow-up without treatment is preferred except for obstructive symptoms, bleeding, and suspicion of malignity. Main symptoms are dysphagia, dysphonia, bleeding, dyspnea, and obstructive sleep apnea. In symptomatic cases, the first described method in surgical treatment is open approach since it is a region difficult to have access to. However, this approach has an increased risk of morbidity and postoperative complications. Transoral robotic surgery, which is a minimally invasive surgical procedure, has advantages such as larger three-dimensional point of view and ease of manipulation due to robotic instruments. In this report, a case at the age of 49 who presented to our clinic with obstructive symptoms increasing within the last year and was found to have lingual thyroid and underwent excision of ectopic thyroid tissue by da Vinci surgical system is presented.

  4. Bcl11b/Ctip2 is required for development of lingual papillae in mice.

    Molecular mechanisms underlying the development and morphogenesis of oral epithelia, comprising the gustatory and nongustatory epithelium, remain unclear. Here, we show that Bcl11b, a zinc finger transcription factor, plays an important role in the development of lingual papillae, especially filiform papillae. In both gustatory and nongustatory epithelium, Bcl11b was expressed in keratin 14-positive epithelial basal cells, which differentiate into keratinocytes and/or taste cells. Loss of Bcl11b function resulted in abnormal morphology of the gustatory papillae: flattened fungiform papillae, shorter trench wall in the foliate and circumvallate papillae, and ectopic invagination in more than half of circumvallate papillae. However, Bcl11b loss caused no effect on differentiation of taste receptor cells. In nongustatory epithelium, the impact of Bcl11b deficiency was much more striking, resulting in a smooth surface on the tongue tip and hypoplastic filiform papillae in the dorsal lingual epithelium. Immunohistochemical analyses revealed that a keratinocyte differentiation marker, Tchh expression was severely decreased in the Bcl11b(-/-) filiform papillae. In addition, expression of Pax9, required for morphogenesis of filiform papillae and its downstream target genes, hard keratins, almost disappeared in the tongue tip and was decreased in the dorsal tongue of Bcl11b(-/-) mice. Gene expression analyses demonstrated a delayed onset of expression of epithelial differentiation complex genes, which disturbed barrier formation in the mutant tongue. These results indicate that Bcl11b regulates the differentiation of keratinocytes in the tongue and identify Bcl11b as an essential factor for the lingual papilla morphogenesis.

    2013-01-01

    We examined the dorsal lingual surfaces of an adult jaguar (Panthera onca) by scanning electron microscopy. The tongue of the jaguar was about 17 cm long, and the center of the lingual apex became hollow. There were 7 vallate papillae in total. The filiform papilla on the lingual apex consisted of a larger main papilla and some secondary papillae. The connective tissue core of the filiform papilla was mountain-like in shape. The connective tissue core of the fungiform papilla was mushroom-like in shape. The filiform papilla on the anterior part of the lingual body was large and cylinder-like in shape. The connective tissue core of the filiform papilla consisted of a big conical papilla and many rod-like papillae. The filiform papilla on the central part of the lingual body was a big conical papilla. The connective tissue core of the filiform papilla consisted of a rod process and bowl-like structure. The vallate papillae were located on both sides of the posterolateral aspects. The vallate papillae were flattened-oval in shape and the papillae were surrounded by a groove and pad. The top of the connective tissue core of the vallate papilla had a rough surface with no spines.

    2014-05-01

    The aim of this study was to retrospectively assess the frequency and localizations of bond failures (BFs) in patients treated with either lingual (TOP-Service für Lingualtechnik GmbH, a 3M Company, Bad Essen, Germany) or buccal (Mini Diamond brackets/Accent molar tubes; Ormco, Orange, Calif) full multibracket appliances in both dental arches. Data were acquired by an independent investigator from the patient records of 3 practitioners. To establish a standardized observation period, the first year of treatment was analyzed for each patient. Statistical analysis comprised the Kruskal-Wallis, Wilcoxon, Mann-Whitney U, and Fisher exact tests. The significance level was set at P <0.05. The mean number of BFs per patient in the first year of treatment did not differ significantly between the lingual group (n = 59; mean age, 31.1 years; mean BFs per patient, 2.63; SD, 2.77; minimum, 0; maximum, 13) and the buccal group (n = 44; mean age, 15.14 years; mean BFs per patient, 2.61; SD, 3.41; minimum, 0; maximum, 14) (P = 0.428) or with respect to sex (lingual group, P = 0.251; buccal group, P = 0.414) or practitioner (lingual group, P = 0.755; buccal group, P = 0.060), but molar attachments were more prone to BFs than were premolar brackets (lingual group, P = 0.015; buccal group, P = 0.049), and premolar brackets were more prone to BF than anterior brackets (lingual group, P = 0.005; buccal group, P = 0.004). With both appliances, a mean of 2.62 BFs per patient in the first year of treatment can be expected; this benchmark provides a reference for patient briefing, which is very important considering the large interindividual variances and budgeting considerations.

    2013-01-01

    Introduction Demineralization of the dental enamel is a finding associated with fixed orthodontic treatment. When an indirect bonding procedure is used in children and adolescents the area beneath the bracket base may be affected. Aim To evaluate if the addition of an extra layer of a hydrophilic resin, to a conventional indirect bonding protocol, can reduce the incidence of demineralization beneath the bracket base. Methods 40 patients under 18 years of age were treated with completely customized lingual appliances. Two different bonding protocols were used either with or without the application of an additional layer of hydrophilic resin. Demineralization beneath the bracket base, after de-bonding, was evaluated by standardized intra-oral photographs. Results The addition of an extra layer of a hydrophilic resin helps to reduce the number of demineralized areas beneath the bracket bases significantly (three times less). The severity of the few remaining defects were minor and without any clinical consequence. Conclusion When bonding a completely customized lingual appliance in children and adolescents, an extra layer of a hydrophilic resin should be added to the teeth. PMID:24025345

    Full Text Available Lingual thyroid is a rare embryological anomaly originated from the thyroid gland failure that descends from the foramen cecum to its normal eutopic pre-laryngeal site. The case in this study was a 39 year old female, presenting with the sensation of a foreign body, progressive dysphagia and dyspnea. Indirect laryngoscopy revealed a large well-defined mass in the tongue base. Imaging studies confirmed the diagnosis of large ectopic lingual thyroid. The surgery was performed via an external cervical approach due to the mass size. The decision on the best treatment looks into the mass position, size, symptoms, airway emergency and medical facilities.

    Pelletier, Cathy A; Dhanaraj, Glory E

    2006-04-01

    There is evidence that a strong, unpalatable, sour bolus improves swallowing in neurogenic dysphagia. It is not known whether other tastes may alter swallowing physiology. This study investigated the effect of moderate versus high taste concentrations (sweet, sour, salty, bitter) and barium taste samples on lingual swallowing pressure in ten healthy young adults, using a three-bulb lingual pressure array secured to the hard palate. Palatability of the samples was analyzed using the nine-point hedonic scale. Results showed that moderate sucrose, high salt, and high citric acid elicited significantly higher lingual swallowing pressures compared with the pressures generated by water. Pressures in the anterior bulb were significantly higher than those recorded from the middle or posterior bulb. There was no significant effect of palatability on lingual swallowing pressures. High salt and citric acid are known to elicit chemesthesis mediated by the trigeminal nerve. These results suggest that chemesthesis may play a crucial role in swallowing physiology. If true, dysphagia diet recommendations that include trigeminal irritants such as carbonation may be beneficial to individuals with dysphagia. However, before this recommendation more research is needed to examine how food properties and their perception affect swallowing in individuals with and without dysphagia.

    Epithelial tissues are characterized by specialized cell-cell junctions, typically localized to the apical regions of cells. These junctions are formed by interacting membrane proteins and by cytoskeletal and extracellular matrix components. Within the lingual epithelium, tight junctions join the apical tips of the gustatory sensory cells in taste buds. These junctions constitute a selective barrier that limits penetration of chemosensory stimuli into taste buds (Michlig et al. J Comp Neurol 502: 1003-1011, 2007). We tested the ability of chemical compounds to permeate into sensory end organs in the lingual epithelium. Our findings reveal a robust barrier that surrounds the entire body of taste buds, not limited to the apical tight junctions. This barrier prevents penetration of many, but not all, compounds, whether they are applied topically, injected into the parenchyma of the tongue, or circulating in the blood supply, into taste buds. Enzymatic treatments indicate that this barrier likely includes glycosaminoglycans, as it was disrupted by chondroitinase but, less effectively, by proteases. The barrier surrounding taste buds could also be disrupted by brief treatment of lingual tissue samples with DMSO. Brief exposure of lingual slices to DMSO did not affect the ability of taste buds within the slice to respond to chemical stimulation. The existence of a highly impermeable barrier surrounding taste buds and methods to break through this barrier may be relevant to basic research and to clinical treatments of taste.

    Full Text Available It is belong to the order Squamata, family, Chamaeleonidae. They have characteristic features of tongue protrusion during capturing prey attracts many research works and assay its velocity during protrusion. Yet little studies touched the anatomical and histological feature of the juvenile tongue and especially the middle tongue region involved in the tongue elongation, the present study aimed to focus on the histological structure of the mid-tongue and clarify its role in projection of the tongue as well as the glandular structure, keratinization of lingual epithelium and proliferation capacity of the fore-tongue region in relation with their feeding habits during the juvenile age. Juvenile Chameleo chameleon are collected from Abu Rawash, north of Giza Governorate, Egypt during summer 2015. Three juvenile developmental stages are used in the present study and categorized according to the gross morphological criteria of head, abdomen and limb lengths. The tongue and hyoid apparatus were removed and photographed. Histological, immunohistochemistry of cytokeratin and stem cell factor and scanning electronic microscopic investigations were carried out on the fore-tongue region, meanwhile only histological studies were done for the median tongue region. Morphometric assessments of number and length of lingual papillae and grades of cytokeratin and stem cell expression were done. Histologically, the dorsal lingual mucosa of the fore-tongue possessed different pattern of lingual papillae including finger-like, club, cubical, biforked and multi-branched papillae. The finger-like papillae are more abundant compared to the other types. The lamina propria of anterior median tongue pad are more glandular and exhibited abundant distribution of PAS-positive tubular glands and moderate alcian blue staining affinity of both alveolar and branched alveolar glands. There is no detected keratinization of the lingual epithelium. Stem cell factor appeared denser on

    Full Text Available Abstract Background Orthodontic treatment with fixed appliances requires - among others - the correct clinical expression of torque, which depends on the precise fitting of archwire and slot. Especially in the lingual technique torque problems become clinically more evident than in labial appliances also with respect to the vertical alignment of teeth due to different distances from the center of resistance. The purpose of the present study was to compare the preciseness of slot dimensions of different lingual bracket systems. Methods Three lingual bracket systems were included in the study (7th Generation and STb, Ormco, Glendora, CA, USA; Incognito, TOP-Service/3 M Unitek, Monrovia, CA, USA. Non destructive analysis of vertical slot dimensions was performed using precision pin gauges (Azurea, Belprahon, Switzerland that were tapered in increments of 0.002 mm (0.00008 inch. The sizes of 240 incisor and canine brackets were measured per system (total: 720. Data were compared using one-way ANOVA. A p-value Results Average slot dimensions were 0.467 mm ± 0.007 mm (0.0184 inch ± 0.0003 inch for the 7th Generation bracket system, 0.466 mm ± 0.004 mm (0.0183 inch ± 0.0001 inch for the STb bracket system and 0.459 mm ± 0.004 mm (0.0181 inch ± 0.0001 inch for the Incognito bracket system. Differences between systems were statistically significant (p Conclusions The analyzed bracket systems for lingual treatment exhibited significant differences in slot dimension that will clinically result in torque play. These aspects must be considered in lingual orthodontic treatment.

    PURPOSE The aim of this study was to analyze the shapes of lingual polished surfaces in lower complete dentures formed by polished surface impressions and to provide reference data for use when manufacturing edentulous trays and lower complete dentures. MATERIALS AND METHODS Twenty-six patients with mandibular edentulism were studied. After lower wax dentures were fabricated, wax was removed from the lingual side of the wax denture and a lingual polished surface impression was obtained with tissue conditioner. The definitive denture was scanned with a three-dimensional scanner, and scanned images were obtained. At the cross-sections of the lingual frenum, lateral incisors, first premolars, first molars, and anterior border of the retromolar pads, three points were marked and eight measurements were taken. The Kruskal-Wallis test and a post hoc analysis with the Mann-Whitney test were performed. RESULTS Each patient showed similar values for the same areas on the left and right sides without a statistically significant difference. The height of the contour of the lingual polished surface at the lingual frenum was halfway between the occlusal plane and lingual border, it moved gradually in a downward direction. The angle from the occlusal plane to the height of the contour of the lingual polished surface was increased as it progressed from the lingual frenum towards the retromolar pads. CONCLUSION The shape of the mandibular lingual polished surface was convex at the lingual frenum, lateral incisors and gradually flattened towards the first molars and retromolar pads. PMID:28018565

    Full Text Available Ergonomics is the way to work smarter and not harder, by designing tools, equipments, work stations so that the task fits to the operator and not vice versa. Lingual orthodontics entails long chair side time, working in indirect vision. The technique requires use of tools bimanually thus hand held mouth mirror becomes more of a handicap and there is always a need to have better indirect vision. Our postdoctoral research work in ergonomics has had an innovative outcome wherein we have devised a method using custom designed mirrors cut in the shape of lower metal stock tray and used by mounting them on those trays for full arch view of maxillary lingual aspect. This ensures upright posture and thus reduced lower back pain and discomfort.

    Full Text Available Although a thyroglossal duct cyst is a congenital anomaly, it can also appear in adults. Despite the presence of embryological remnants, it is still unclear why the cyst should suddenly develop later in life. We report a case of a 46-year-old male with an extravasation mucocele arising from a long-standing lingual thyroglossal duct remnant. MRI demonstrated a lingual cystic lesion near the hyoid bone associated with a suprahyoid tract-like structure masquerading as a thyroglossal duct cyst. However, histopathological examination demonstrated a mucocele secondary to a rupture of a thyroglossal duct remnant with numerous intramural heterotopic salivary glands. We propose a new mechanism of an acquired cystic formation of this congenital disease that excessive production of mucus from heterotopic salivary glands and a physical trauma such as swallowing may lead to extravasation of mucus from the thyroglossal duct.

  7. Lingual Kinematics in Dysarthric and Nondysarthric Speakers with Parkinson's Disease

    Min Ney Wong

    2011-01-01

    Full Text Available Articulatory dysfunction is recognised as a major contributor to the speech disturbances seen in Parkinson's disease (PD. The present study aimed to compare lingual kinematics during consonant production within a sentence in eight dysarthric (DPD and seven nondysarthric (NDPD speakers with PD with those of eleven nonneurologically impaired normal participants. The tongue tip and tongue back movements of the participants during sentence production were recorded using electromagnetic articulography (EMA. Results showed that both the DPD and NDPD had deviant articulatory movement during consonant production that resulted in longer duration of consonant production. When compared with the NDPD group, the DPD group primarily exhibited increased range of lingual movement and compatible duration of production with an accompanying increase in maximum velocity, maximum acceleration, and maximum deceleration. These findings are contrary to proposed theories that suggest articulatory imprecision in dysarthric speakers with PD is the outcome of reduced range of articulatory movement.

    Background In order to choose the appropriate implant size and to prevent complications, an oral surgeon must know the size and shape of the mandible. In the posterior mandibular region, a lingual undercut is often found and could represent a difficulty hard to manage if a lingual or buccal perforation occur. A large series of computed tomography (CT) images of the mandibular first molar was evaluated and the bone morphology, the prevalence and the degree of the lingual concavity in the first molar region were studied. Material and Methods One hundred and fifty-one computed tomography (CT) examinations of patients were retrospectively evaluated to determine anatomical variations in bone morphology in the submandibular fossa region. Results A total of 151 subjects were included, consisting of 64 males (M) (42.4%) and 87 females (F) (57.6%). The under-cut type ridge was present in 64.2% of the cases. The concavity angle was 66.6 ± 8.9° (M) and 71.6 ± 8.4° (F) and the linear concavity depth 4.5 ± 2.3 mm (M) and 3.1 ± 1.7 mm (F) (p>0.05). Conclusions Mandibles with any lingual concavity present a potential increased risk of lingual cortical perforation during implant placement surgery. CT imaging allows characterizing the anatomy of the submandibular fossa and provides other important information for the preoperative assessment of the posterior mandible for dental implants placement.

    To investigate the composition and the microstructural and mechanical characterization of three different types of lingual brackets. Incognito™ (3M Unitek), In-Ovation L (DENTSPLY GAC) and STb™ (Light Lingual System, ORMCO) lingual brackets were studied under the scanning electron microscope employing backscattered electron imaging and their elemental composition was analysed by energy-dispersive X-ray microanalysis. Additionally, Vickers hardness was assessed using a universal hardness-testing machine, and the indentation modulus was measured according to instrumented indentation test. Two-way analysis of variance was conducted employing bracket type and location (base and wing) as discriminating variable. Significant differences among groups were allocated by post hoc Student-Newman-Keuls multiple comparison analysis at 95% level of significance. Three different phases were identified for Incognito and In-Ovation L bracket based on mean atomic number contrast. On the contrary, STb did not show mean atomic contrast areas and thus it is recognized as a single phase. Incognito is a one-piece bracket with the same structure in wing and base regions. Incognito consists mainly of noble metals while In-Ovation L and STb show similar formulations of ferrous alloys in wing and base regions. No significant differences were found between ferrous brackets in hardness and modulus values, but there were significant differences between wing and base regions. Incognito illustrated intermediate values with significant differences from base and wing values of ferrous brackets. Significant differences exist in microstructure, elemental composition, and mechanical properties among the brackets tested; these might have a series of clinical implications during mechanotherapy. © The Author 2013.

    Full Text Available A Frenum is a fold of mucous membrane, usually with enclosed muscle fibers, that attaches the lips and cheeks to the alveolar mucosa and/or mucosa and underlying periosteum. Tongue tie or ankyloglossia is a developmental anomaly of the tongue characterized by an abnormally short, thick lingual frenum resulting in limitation of tongue movement. It causes difficulty in speech articulation due to limitation in tongue movement. In this article we report a case of 24 years old female with Tongue tie, complaining of difficulty in speech. It was surgically treated with uneventful healing and good patient satisfaction.

    2009-01-01

    Full Text Available Background: Oral lichen planus is an inflammatory chronic disease with an autimmune pathogenesis and unknown etiology that affects oral mucosa, with or without the involvement of the skin and other mucous membranes. The principal histological characteristics are the degeneration of the basal cell layer and the abnormal infiltration of inflammatory cells into the subepithelial layer of connective tissue. Objectives: This study is aimed to appraise if lingual lichen planus (LLP is sustained by alteration of the oral microcirculation and if this abnormal vascularisation increases the degeneration of basal keratinocytes and the disruption of the basement membrane. Materials and Methods: Fifteen patients with a histological diagnosis of LLP with higher degree of degeneration of the basement membrane, fifteen LLP patients with lower degree of basement membrane (BM degeneration and fifteen healthy patients were included in the study. The microcirculation of the left margin of the lingual mucosa of all the patients and subjects was analysed with the videocapillaroscopy. The following parameters were analyzed on each capillaroscopic image: c0 apillary loop length, loop diameter, and capillary density. The results obtained by videocapillaroscopy software were subjected to statistical analysis using Mann Whitney U-test (P < 0.001. Statistical analysis was performed using PAST software, v. 1.53. Results: Capillary density, loop length, and total diameter showed statistically significant differences between LLP patients with histologically lower degree of BM degeneration and healthy subjects and a meaningful significant difference between LLP patients with higher degree of BM degeneration. Conclusions: A remarkable increase in capillary density was showed by videocapillaroscopic exam. The increased value of the density could be associated with angiogenesis mechanism and it could be an indicator of the evolutionary condition of LLP. Videocapillaroscopy may be

    The inferior alveolar nerve is sometimes affected by periapical pathoses and mandibular cysts. However, mandibular intraosseous lesions have not been reported to disturb the lingual nerve. A case of simultaneous paresthesia of the right lingual nerve and the right inferior alveolar nerve is presented. The possible mechanisms of this extremely uncommon condition are discussed.

    This paper addresses the design and implementation of BiLingual Information Retrieval system on the domain, Festivals. A generic platform is built for BiLingual Information retrieval which can be extended to any foreign or Indian language working with the same efficiency. Search for the solution of the query is not done in a specific predefined set of standard languages but is chosen dynamically on processing the user's query. This paper deals with Indian language Tamil apart from English. The task is to retrieve the solution for the user given query in the same language as that of the query. In this process, a Ontological tree is built for the domain in such a way that there are entries in the above listed two languages in every node of the tree. A Part-Of-Speech (POS) Tagger is used to determine the keywords from the given query. Based on the context, the keywords are translated to appropriate languages using the Ontological tree. A search is performed and documents are retrieved based on the keywords. With...

    This study investigated the feasibility, safety and efficacy of Coblation endoscopic lingual lightening (CELL) surgery for obstructive sleep apnea (OSA). This study was a retrospective case series in a tertiary referral sleep center. Twenty-five adults with moderate to severe OSA and determined to have retropalatal and tongue base obstruction based on Friedman tongue position III and fiberoptic endoscopy underwent CELL in combination with modified uvulopalatopharyngoplasty, known as relocation pharyngoplasty. CELL involves transoral resection of tongue base muscle tissue and lingual tonsil using Coblation under endoscopic guidance. The mean operation time for CELL was 42.6 ± 13.7 min. Total blood loss for CELL plus relocation pharyngoplasty was <50 ml in all patients. Mean postoperative pain score (sum of total pain scores/sum of total hospitalization day, visual analog scale, 0-10) was 2.6 ± 0.6. Postoperative bleeding and taste disturbance extending beyond 3 months occurred in one patient (4 %) individually. No patients reported tongue weakness or speech dysfunction. Epworth sleepiness scale improved from 9.6 ± 4.9 to 7.5 ± 4.3 (p = 0.023). Apnea-hypopnea index decreased from 45.7 ± 21.7 to 12.8 ± 8.2 events/hour (p < 0.001) 6 months after surgery. The overall response rate was 80 %. CELL is feasible, safe and effective in treating tongue base obstruction in OSA patients who underwent simultaneous relocation pharyngoplasty.

    2007-01-01

    Objective: Microcapsule chemoembolism is a promising treatment of tumors. We describe a deep lingual arterial embolization of tongue carcinoma with microcapsuled carboplatinum. Methods: Lingual artery cast specimens from cadavers were microscopically examined, and 78 patients with tongue cancer were recruited and treated with the deep lingual arterial embolization therapy. Results: Microcapsule embolism occurred approximately at the fifth or sixth level of the deep lingual artery branches. The five-year survival rate was 88.5% (69 out of 78), and the ten-year survival rate 52.6% (41 out of 78). Conclusion:The deep lingual arterial embolization of tongue carcinoma with microcapsuled carboplatinum is an effective therapy to treat carcinoma in mid-margin or mid-body of the tongue.

    The dorsal lingual surfaces of the raccoon dogs (Nyctereutes procyonoides) and fox (Vulpes vulpes japonica) were examined by scanning electron microscopical (SEM) observations. The distribution and type of the lingual papillae found in the raccoon dog were similar to those in the fox. Filiform, fungiform, foliate and vallate papillae were observed. The filiform papillae were distributed over the entire dosal surface of the tongue. Each filiform papilla on the apical surface of the tongue had several pointed processes. The filiform papillae of the lingual body consisted of a main papilla and some secondary papillae. The fungiform papillae were present rounded bodies, and more densely distributed on the lingual apex. The foliate papillae were seen on the dorsolateral aspect of the tongue. The vallate papillae were located on both sides of the posterior end of the lingual body. Each papilla was surrounded by groove and crescent pad. On the periphery of the papillae, large conical papillae were observed.

    Purpose: To evaluate if two pharmacological agents, Tempol and D-methionine (D-met), are able to prevent oral mucositis in mice after exposure to ionizing radiation {+-} cisplatin. Methods and Materials: Female C3H mice, {approx}8 weeks old, were irradiated with five fractionated doses {+-} cisplatin to induce oral mucositis (lingual ulcers). Just before irradiation and chemotherapy, mice were treated, either alone or in combination, with different doses of Tempol (by intraperitoneal [ip] injection or topically, as an oral gel) and D-met (by gavage). Thereafter, mice were sacrificed and tongues were harvested and stained with a solution of Toluidine Blue. Ulcer size and tongue epithelial thickness were measured. Results: Significant lingual ulcers resulted from 5 Multiplication-Sign 8 Gy radiation fractions, which were enhanced with cisplatin treatment. D-met provided stereospecific partial protection from lingual ulceration after radiation. Tempol, via both routes of administration, provided nearly complete protection from lingual ulceration. D-met plus a suboptimal ip dose of Tempol also provided complete protection. Conclusions: Two fairly simple pharmacological treatments were able to markedly reduce chemoradiation-induced oral mucositis in mice. This proof of concept study suggests that Tempol, alone or in combination with D-met, may be a useful and convenient way to prevent the severe oral mucositis that results from head-and-neck cancer therapy.

    2003-01-01

    A non-invasive protocol was developed to assess tongue and cheek movements during mastication and to evaluate the temporal relationship between mastication and the initiation of pharyngeal swallowing. Typical adults (three males and three females) were monitored during chewing. Miniature pressure transducers were bonded unilaterally to the buccal and lingual surfaces of the first mandibular molar and the buccal surface of the first maxillary molar on each subject's preferred chewing side. Surface electromyography of the ipsilateral masseter muscle was recorded as an indicator of jaw-closing activity. Pressure and electromyography (EMG) recordings were time-linked to simultaneous B-mode ultrasound imaging of the oral cavity using a submental, coronal view aligned with the first mandibular molar. The intervals between peak pressure recorded at each pressure transducer and peak jaw-closing activity for each masticatory cycle were not statistically different [analysis of variance (anova), P=0.9856] and displayed large statistical variation. These intervals were not different at the beginning of the trials (hard biscuit) than they were at the completion of mastication when the cookie had been broken down to a paste/puree consistency bolus. The interval between the last chewing stroke and the initiation of swallowing was 0.92 +/- 0.34 s). No significant difference existed among subjects for this time interval (anova, P=0.382).

    During the last few years, green iguanas (Iguana iguana) have turned out to be one of the most popular pets. They are omnivorous. In their way of feeding, this crucial function is performed by capturing of the preys and mostly, this is carried out by the tongue. The role of the tongue is also fundamental during the intra-oral transport and during the swallowing of food. This has been reported in several studies about chameleons, agamids and iguanids, nevertheless published data about the mechanisms of capturing and swallowing the prey, and the morphological descriptions about the tongue epithelium, are scarce. Therefore, the aim of this present study was to analyse the morphology of the lingual epithelium in green iguanas by scanning electron microscopy. Three different areas were demonstrated on the tongue surface: the tongue tip, characterized by a smooth epithelium without papillae, a foretongue, completely covered by numerous closely packed cylindriform papillae, and a hindtongue with conical-like papillae. Some taste buds were recognized on the middle and the posterior parts of the tongue. Different functional roles could be hypothesized for the three tongue areas: the tongue tip could have a role related to the movements of the prey immediately after the capturing, while the middle papillae and the hindtongue could have an important role concerning the swallowing phase.

    Aim: Ankyloglossia, commonly known as tongue-tie, is a congenital oral anomaly characterized by a short lingual frenulum that may contribute to feeding, speech and mechanical problems. The purpose of this study is to compare the advantages of laser vis-à-vis conventional frenectomy in both intra- and post-surgical phases. Methods: This study took into consideration two patients, who were respectively 9 and 10-year-old. The first one underwent a common surgical procedure. A Nd:Yap laser device with a micropulsed wavelength of 1340 nm and power of 8 watts was used for the second. The postsurgical discomfort and healing characteristics were evaluated. Results: The results indicated that the Nd:Yap laser has the following advantages when compared to the conventional frenectomy: 1) soft tissue cutting was efficient, with no bleeding, giving a clear operative field; 2) there was no need to use sutures; 3) the surgery was less time-consuming; 4) there was no postsurgical infection and no need for analgesics or antibiotics; 5) wound contraction and scarring were decreased or eliminated; 6) despite the initial slowness of the healing process, the complete and final recovery was faster. Conclusion: Considering the above elements, it is possible to assert that the laser frenectomy has a series of unquestionable advantages if compared to the conventional surgical technique.

    Background: Online news reports are increasingly becoming a source for event based early warning systems that detect natural disasters. Harnessing the massive volume of information available from multilingual newswire presents as many challenges as opportunities due to the patterns of reporting complex spatiotemporal events. Results: In this article we study the problem of utilising correlated event reports across languages. We track the evolution of 16 disease outbreaks using 5 temporal aberration detection algorithms on text-mined events classified according to disease and outbreak country. Using ProMED reports as a silver standard, comparative analysis of news data for 13 languages over a 129 day trial period showed improved sensitivity, F1 and timeliness across most models using cross-lingual events. We report a detailed case study analysis for Cholera in Angola 2010 which highlights the challenges faced in correlating news events with the silver standard. Conclusions: The results show that automated heal...

    Full Text Available Objective: This research is designed to study palatographic specification of lingual- palatal consonants in Persian language. Since there is not any research about the lingua-palatal contacts in Persian language, this research is designed to determine these “normal” contact patterns and variability of Persian consonant production. Materials and Methods: In this study 16 consonants have been studied. Subjects were 4 normal adults. Each person repeated every consonant 10 times in (CVCV syllable with vowel /a/. Frame of maximum contact for each consonant was determined. Individual and overall representative frames obtained from those frames. Results: There are different patterns of variability between Persian consonants. Consonants /n/, /ſ/, and /l/ display more variable articulation and stops and affricates display less variable articulation than others. Conclusion: Persian consonants have different contact patterns. These findings are in accordance with previous studies in other languages.

    A 22-year-old man presented to our department with a mass on the base of his tongue. He had a cavernous voice causing a moderate speech disorder, and he had some difficulty in swallowing. He had severe problems with sleep, associated with apnoea. In a fibreoptic laryngoscopic examination, a large 4×5 cm vascular mass was detected extending from the base of the patient's tongue to his epiglottis. It covered the epiglottis. Thyroid scintigraphy showed only thyroid tissue on the base of the tongue. Surgery was initiated transorally under the guidance of a rigid endoscope, but as the mass continued extended to the epiglottis, a transhyoid approach was taken. At a 3-month follow-up, the patient was symptom free. Electrocautery-assisted resection under the guidance of a rigid endoscope can reliably be used in surgery of a lingual thyroid. However, a transhyoid approach provides a better view and also helps in achieving haemostasis.

    Saliva is essential for taste function and not only does saliva influence taste reception, but also taste perception initiates salivation. As a first step in investigating circuits involved in gustatory-salivary reflexes, we have studied the morphology of the rat inferior salivatory nucleus (ISN), which contains parasympathetic secretomotor neurons that control the parotid and lingual (von Ebner) salivary glands. By applying the fluorescent label Fluorogold to the cut end of the glossopharyngeal nerve, the neurons supplying only the lingual salivary glands were labeled. Confocal microscopy and three-dimensional reconstruction were used to analyze the labeled neurons in the horizontal plane to determine their morphological characteristics. Additional neurons were studied in the coronal plane to determine the influence of the plane of section on neuron morphology. Reconstructions indicated that inferior salivatory neurons extend in a rostral-caudal distribution just adjacent to the medial border of the nucleus of the solitary tract (NST). There is considerable morphological variability among neurons, with neurons having up to 6 primary dendrites and 17 dendritic segments that extend a maximum of 834 microm from the soma. However, although ISN neurons vary in the size and complexity of their dendritic trees, distributions of all measures of neuron morphology are unimodal, indicating that distinct groups of neurons are not revealed based on these measures. There is, however, variability in the orientation pattern of the dendritic trees that is not represented in either the population or mean measures. Individual neurons can be categorized with either mediolateral, rostro-caudal or no apparent preferred orientation. Comparisons of neurons in rostral, intermediate or caudal third of the ISN revealed regional differences in neuron morphology; neurons in the caudal third have significantly longer dendrites than those in the intermediate or rostral third. Thus, while ISN

  15. Distribution of Y-receptors in murine lingual epithelia.

    Directory of Open Access Journals (Sweden)

    Maria D Hurtado

    Full Text Available Peptide hormones and their cognate receptors belonging to neuropeptide Y (NPY family mediate diverse biological functions in a number of tissues. Recently, we discovered the presence of the gut satiation peptide YY (PYY in saliva of mice and humans and defined its role in the regulation of food intake and body weight maintenance. Here we report the systematic analysis of expression patterns of all NPY receptors (Rs, Y1R, Y2R, Y4R, and Y5R in lingual epithelia in mice. Using four independent assays, immunohistochemistry, in situ hybridization, immunocytochemistry and RT PCR, we show that the morphologically different layers of the keratinized stratified epithelium of the dorsal layer of the tongue express Y receptors in a very distinctive yet overlapping pattern. In particular, the monolayer of basal progenitor cells expresses both Y1 and Y2 receptors. Y1Rs are present in the parabasal prickle cell layer and the granular layer, while differentiated keratinocytes display abundant Y5Rs. Y4Rs are expressed substantially in the neuronal fibers innervating the lamina propria and mechanoreceptors. Basal epithelial cells positive for Y2Rs respond robustly to PYY(3-36 by increasing intracellular Ca(2+ suggesting their possible functional interaction with salivary PYY. In taste buds of the circumvallate papillae, some taste receptor cells (TRCs express YRs localized primarily at the apical domain, indicative of their potential role in taste perception. Some of the YR-positive TRCs are co-localized with neuronal cell adhesion molecule (NCAM, suggesting that these TRCs may have synaptic contacts with nerve terminals. In summary, we show that all YRs are abundantly expressed in multiple lingual cell types, including epithelial progenitors, keratinocytes, neuronal dendrites and TRCs. These results suggest that these receptors may be involved in the mediation of a wide variety of functions, including proliferation, differentiation, motility, taste perception

    1998-12-01

    Changes in the lingual epithelium during ontogenesis and after induced metamorphosis in Ambystoma mexicanum are described as observed by light microscopy and scanning electron microscopy. The epithelium of the tongue is always multilayered in the larva as well as in the adult. It consists of a stratum germinativum with little differentiated basal cells and a stratum superficiale (superficial layer) with specialized superficial cells and goblet cells. Usually, there are more than two layers because of a stratum intermedium consisting of replacement cells. The apical cell membrane of the superficial cells is perforated by fine pores. Its most typical feature are microridges. Maturing superficial cells possess microvilli. Goblet cells occur in early larvae primarily in the centre of the tongue. They spread throughout the dorsal face of the tongue as their numbers increase during ontogenesis. The small apices of the goblet cells are intercalated in the wedges between the superficial cells. Leydig cells are not found on the larval tongue but on that of adults. Due to metamorphosis, the epithelium of the tongue changes. It is furrowed in its anterior part. The furrows house the openings of the lingual glands. The surface is further modulated by ridges which are densely coated by microvilli and which bear the taste buds. The villi of the tongue which lack extrusion pores show cilia and microvilli but lack microridges. The Leydig cells disappear during metamorphosis. In addition to the two types of goblet cells found in different regions of the glandular tubules, goblet cells occur in the caudal part. They secrete directly into the cavity of the mouth. The posterior part is characterised by a dense coat of cilia.

    Lingual and labial frenulectomy are commonly performed as an outpatient procedure, either in an office setting or under general anesthesia. Frenulectomy is generally regarded by both otolaryngologists and dentists as a straightforward and low-risk procedure with limited evidence-based indications and similarly few contraindications. We describe two cases of hypovolemic shock occurring after outpatient frenulectomy requiring emergent interventions of cardiopulmonary resuscitation and blood transfusion. These rare, but life-threatening outcomes warrant recognition as potential complications for the presumed benign labial and lingual frenulectomy. We additionally briefly review indications for upper labial and lingual frenulectomy. Copyright © 2017 Elsevier B.V. All rights reserved.

    2015-09-01

    Pierre-Robin Sequence (PRS) is defined as the triad of micrognathia, glossoptosis, and cleft palate and affects approximately 1/8500 births. Airway obstruction is common in infants with PRS and results from glossoptosis leading to pharyngeal obstruction. Any procedure that increases the severity of glossoptosis, such as lingual frenulectomy, may increase the risk of obstruction or aggravate existing obstruction. This report discusses two cases of significant airway decompensation after lingual frenulectomy requiring surgical intervention in infants with PRS. We suggest that lingual frenulectomy be contraindicated in infants with PRS or suspected PRS due to the possible increased risk of airway obstruction. Copyright © 2015 Elsevier Ireland Ltd.

    2014-11-01

    To evaluate microleakage when two types of retainer wires were bonded with two light cured and a self cured lingual retainer composites. Total 120 freshly extracted human mandibular incisor teeth were collected and separated into six subgroups of 20 teeth each. Two different wires, a 0.036 inch hard round stainless steel (HRSS) wire sandblasted at the ends and 0.0175 inch multistranded wire bonded onto the lingual surfaces of the incisors with three different types of composite resins of 3M company; Concise Orthodontic (self-cure), Transbond XT (light-cure) and Transbond LR (light-cure). Specimens were further sealed with a nail varnish, stained with 0.5% basic fuchsine for 24 hours, sectioned and examined under a stereomicroscope, and scored for microleakage for the enamel-composite and wire-composite interfaces. Statistical analysis was performed by Kruskal-Wallis and Mann-Whitney U-tests. For HRSS wire, at the enamel-composite interface, the microleakage was least with Transbond LR followed by Concise Orthodontic and greatest for Transbond XT (p<0.05). At the wire composite interface too, the microleakage was in order of Transbond LR

    Full Text Available This article introduces the reader to the theory of a lingual-cultural personality and lingual-cultural types in particular. A lingual-cultural type is a generalized image of personalities whose behavior and values significantly influ-ence the culture in general and is a representative of ethnic and social variety of the society. The type of an American Lawyer is being analyzed, because in the United States of America, unlike any other country, the role of a lawyer has a pervasive shared understanding. The author examines how lawyers are repre-sented in US popular culture, specifically exploring presentations in legal and crime fiction. She also analyzes results from a survey of 100 Russian students, exploring their perceptions of the lingual-cultural type of US lawyers

    A 36 year old diabetic man developed a pure motor hemiplegia (PMH) associated with an ipsilateral lingual palsy. Magnetic resonance imaging revealed a pontine infarct. Lingual palsies have never been reported in patients with PMH so far, but may be associated with other lacunar syndromes such as the "dysarthria-clumsy hand syndrome". This observation supports the hypothesis that corticohypoglossal pathways may have bilateral and assymetrical projections.

    Purpose: To study MR findings for clues to the diagnosis of lingual thyroid. Material and methods: MR findings and clinical and scintigraphic data of 5 cases of lingual thyroid were reviewed and the MR findings were compared to those of 16 cases of other submucosal lesions in the base of the tongue. Results: Four of the 5 patients with lingual thyroid were women and all had hypothyroidism. MR imaging depicted lingual thyroid in the midline in the base of the tongue (n=5) and additional ectopic thyroid glands in the floor of the mouth (n=2) or between the right and left sternohyoid muscles (n=1). Ectopic thyroid glands appeared isointense or hyperintense relative to muscle tissue on T1-weighted images and showed slight or fair contrast enhancement. All glands had low to intermediate T2 signal, which was also seen in 1 case of non-Hodgkin's lymphoma and 1 case of adenoid cystic carcinoma. All ectopic thyroid glands had well-defined margins, whereas malignant tumors tended to have ill-defined margins and to invade the surrounding structures. All but the 5 cases of lingual thyroid had an MR-demonstrable thyroid gland in the normal cervical position. Conclusion: A well-defined mass of low-intermediate T2 signal in the midline base of the tongue, neither with invasive tendency nor with a cervical thyroid gland in the normal site on MR imaging, may strongly indicate lingual thyroid.

    Full Text Available Objectives: Lingual orthodontics differs in biomechanics as compared to labial system and has biomechanical advantages. Although theoretical approaches have explained the differences between labial and lingual orthodontics, the finite element method (FEM may be better suited to analyze these differences. This study analyzes the effect of vertical and horizontal forces together on the tooth using FEM. Materials and Methods: An extracted right maxillary central incisor was radiographed and was used to create a solid model using ANSYS. The geometric model was converted into a finite element model with the help of ANSYS software. The model consists of 27,000 elements and 30,000 nodes. Two force vectors (vertical and horizontal were applied labially and lingually at 3 different heights- 4 mm, 5 mm and 6 mm from the incisal edge. Results: In the labial system, the net force vector passes through the center of resistance (CR and brings about intrusion. The net force vector in lingual orthodontics does not pass through the center of resistance and produces lingual tipping of the incisors. Conclusion: Intrusion and retraction forces bring about tipping of incisors in lingual orthodontics. The same amount of intrusion and retraction forces brings about intrusion of incisors in labial orthodontics. Therefore, direction and amount of forces should be carefully and judiciously applied after taking into consideration the resultant biomechanical differences.

    Full Text Available Abstract Background Online news reports are increasingly becoming a source for event-based early warning systems that detect natural disasters. Harnessing the massive volume of information available from multilingual newswire presents as many challanges as opportunities due to the patterns of reporting complex spatio-temporal events. Results In this article we study the problem of utilising correlated event reports across languages. We track the evolution of 16 disease outbreaks using 5 temporal aberration detection algorithms on text-mined events classified according to disease and outbreak country. Using ProMED reports as a silver standard, comparative analysis of news data for 13 languages over a 129 day trial period showed improved sensitivity, F1 and timeliness across most models using cross-lingual events. We report a detailed case study analysis for Cholera in Angola 2010 which highlights the challenges faced in correlating news events with the silver standard. Conclusions The results show that automated health surveillance using multilingual text mining has the potential to turn low value news into high value alerts if informed choices are used to govern the selection of models and data sources. An implementation of the C2 alerting algorithm using multilingual news is available at the BioCaster portal http://born.nii.ac.jp/?page=globalroundup.

  9. Vocal-tract filtering by lingual articulation in a parrot.

    Human speech and bird vocalization are complex communicative behaviors with notable similarities in development and underlying mechanisms. However, there is an important difference between humans and birds in the way vocal complexity is generally produced. Human speech originates from independent modulatory actions of a sound source, e.g., the vibrating vocal folds, and an acoustic filter, formed by the resonances of the vocal tract (formants). Modulation in bird vocalization, in contrast, is thought to originate predominantly from the sound source, whereas the role of the resonance filter is only subsidiary in emphasizing the complex time-frequency patterns of the source (e.g., but see ). However, it has been suggested that, analogous to human speech production, tongue movements observed in parrot vocalizations modulate formant characteristics independently from the vocal source. As yet, direct evidence of such a causal relationship is lacking. In five Monk parakeets, Myiopsitta monachus, we replaced the vocal source, the syrinx, with a small speaker that generated a broad-band sound, and we measured the effects of tongue placement on the sound emitted from the beak. The results show that tongue movements cause significant frequency changes in two formants and cause amplitude changes in all four formants present between 0.5 and 10 kHz. We suggest that lingual articulation may thus in part explain the well-known ability of parrots to mimic human speech, and, even more intriguingly, may also underlie a speech-like formant system in natural parrot vocalizations.

    Full Text Available From the Problems of Dictionaries and Multi-lingual Corpora The article describes the work on a number of dictionaries being developed by the Corpus Linguistics and Semantics Group of the Institute of Slavic PAS. They include “Contemporary Bulgarian-Polish Dictionary”, “Bulgarian-Polish Online Dictionary” and “Russian-Bulgarian-Polish Dictionary”. The dictionaries differ in the numbers of entries, as well as in the different degrees of their connection with parallel corpora being elaborated under the “Clarin” project. All the discussed dictionaries are similar with respect to their use of traditional, syntactic classifiers and of semantic classifiers, introduced for the first time in the existing lexicographical practice. Thanks to the “Polish-Bulgarian-Russian Corpus”, the Group has managed to verify the results of contrasting Polish and Bulgarian in the light of scope-based logical quantification. Thanks to the Russian material added to the trilingual corpus, the researchers have managed to confirm the fact that from the viewpoint of “incomplete quantification” Russian and Polish (synthetic languages behave similarly, and are opposed to the analytic Bulgarian.

    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.

    Full Text Available The aim of this study was to retrospectively investigate the outcomes of patients who underwent one-stage onlay or inlay urethroplasty using a lingual mucosal graft (LMG after failed hypospadias repairs. Inclusion criteria included a history of failed hypospadias repair, insufficiency of the local skin that made a reoperation with skin flaps difficult, and necessity of an oral mucosal graft urethroplasty. Patients were excluded if they had undergone a failed hypospadias repair using the foreskin or a multistage repair urethroplasty. Between January 2008 and December 2012, 110 patients with failed hypospadias repairs were treated in our center. Of these patients, 56 underwent a one-stage onlay or inlay urethroplasty using LMG. The median age was 21.8 years (range: 4-45 years. Of the 56 patients, one-stage onlay LMG urethroplasty was performed in 42 patients (group 1, and a modified Snodgrass technique using one-stage inlay LMG urethroplasty was performed in 14 (group 2. The median LMG urethroplasty length was 5.6 ± 1.6 cm (range: 4-13 cm. The mean follow-up was 34.7 months (range: 10-58 months, and complications developed in 12 of 56 patients (21.4%, including urethrocutaneous fistulas in 7 (6 in group 1, 1 in group 2 and neourethral strictures in 5 (4 in group 1, 1 in group 2. The total success rate was 78.6%. Our survey suggests that one-stage onlay or inlay urethroplasty with LMG may be an effective option to treat the patients with less available skin after failed hypospadias repairs; LMG harvesting is easy and safe, irrespective of the patient′s age.

    We observed the three-dimensional structures of the external surface and connective tissue cores CTCs, after exfoliation of the epithelium of the lingual papillae (filiform, fungiform, and foliate papillae) of the common hippopotamus (Hippopotamus amphibius amphibius) using scanning electron microscopy and conventional light microscopy. Following unique features were found; typical vallate papillae with a circumferential furrow were not observable. Instead, numerous large fungiform papillae were rather densely distributed on the posterior of the lingual prominence. Taste buds were observable only on the dorsal epithelium. Serous lingual gland was not seen in the lamina propria; however, mucous-rich mixed lingual glands were found and in a few of orifices were seen on the large fungiform tops. Lingual prominence was diminished their width. Rather long and slender conical papillae were distributed on the lingual prominence and were similar to nonruminant herbivore, that is donkey. Beside this narrow lingual prominence, lateral slopes were situated with numerous short spine-like protrusions. After removal of the epithelium, CTCs of lateral slopes exhibited attenuated flower bud structures. Large-conical papillae were situated on the root of the tongue. These large conical papillae were not seen among ruminants and seen on the lingual root of omnivores and carnivores. It implies that lingual structure of common hippopotamus possessed mixed characteristics between Perissodactyls, Ruminantia, and nonherbivores such as Suiformes because of their unique evolutionally taxonomic position. Moreover, adaptation for soft grass diet and associating easier mastication may be also affecting these mixed morphological features of the tongue.

    In this study, we aimed to describe the morphological characteristics of the lingual papillae in two species of Otariidae family by stereomicroscopy and scanning electron microscopy. We used tongues of two South American Otariidae species. The tongues were elongated and terminated in bifid apex and there was no median sulcus on the dorsal lingual surface. The most numerous type of lingual papilla was filiform in the South American fur seal (SASL) and entire dorsal lingual surface was covered by these filiform papillae but the dorsal surface of the tongue of the South American sea lion was covered by numerous polygonal projections, which were different in size. Fungiform papillae were detected in only SASL and they randomly distributed on the lingual apex and body, and some fungiform papillae were collected into twosome or threesome groups on the posterior part of the lingual body. Circumvallate papilla was found in the center of the lingual radix of South American sea lion. Thread-like conical papillae were common for both species and they located on the lingual radix. We determined that lingual surface morphology was completely different in each species, although they were members of the same family, Otariidae.

    In obstructive sleep apnea (OSA) patients, inspiratory activation (IA) of lingual muscles protects the upper airway from collapse. We aimed to determine when rats' lingual muscles exhibit IA. In 5 Sprague-Dawley and 3 Wistar rats, we monitored cortical EEG and lingual, diaphragmatic and nuchal electromyograms (EMGs), and identified segments of records when lingual EMG exhibited IA. Individual segments lasted 2.4-269 s (median: 14.5 s), most (89%) occurred during slow-wave sleep (SWS), and they collectively occupied 0.3-6.1% of the total recording time. IA usually started to increase with a delay after SWS onset and ended with an arousal, or declined prior to rapid eye movement sleep. IA of lingual EMG was not accompanied by increased diaphragmatic activity or respiratory rate changes, but occurred when cortical EEG power was particularly low in a low beta-1 frequency range (12.5-16.4 Hz). A deep SWS-related activation of upper airway muscles may be an endogenous phenomenon designed to protect the upper airway against collapse.

    The aim of this study was to compare the retention of conventional mandibular complete dentures with that of mandibular complete dentures having lingual flanges constructed with flexible acrylic resin "Versacryl." The study sample comprised 10 completely edentulous patients. Each patient received one maxillary complete denture and two mandibular complete dentures. One mandibular denture was made of conventional heat-cured acrylic resin and the other had its lingual flanges made of flexible acrylic resin Versacryl. Digital force-meter was used to measure retention of mandibular dentures at delivery and at 2 weeks and 45 days following denture insertion. The statistical analysis showed that at baseline and follow-up appointments, retention of mandibular complete dentures with flexible lingual flanges was significantly greater than retention of conventional mandibular dentures (P dentures, retention of dentures increased significantly over the follow-up period (P complete dentures improved denture retention.

    1989-10-01

    We studied the morphology and ultrastructure of the bat (Pipistrellus k.k. and Rhinolophus f.e.) deep posterior lingual glands (Ebner's glands) during hibernation, summer and after stimulation with pilocarpine. Ebner's glands are formed by serous tubulo-alveolar adenomeres and by an excretory system organized in intercalated ducts, long excretory ducts and a main excretory duct. The latter opens in the vallum which surrounds the circumvallate papillae and in the groove of the foliate papillae. The secretory cells, which lack basal folds, show abundant and dense granules (PAS+, Alcian blue -), microvilli (scarce during hibernation), a Golgi apparatus (well developed during summer and after stimulation with pilocarpine), a large nucleus and RER cisternae stacked at the basal pole. Centrioles, lipid droplets, heterogeneous bodies (in content and density, probably lipofuscin bodies), lysosomal multivesicular bodies and large, dense granules with a microcrystalline structure were also encountered. The lateral membranes of adjacent cells are joined by desmosomes; their interdigitations are neither numerous nor prominent during summer. Microfilaments, often gathered in small bundles, lie in the lateral, peripheral cytoplasm without any relation with desmosomes. In summer and particularly after stimulation with pilocarpine, the apical pole of the secretory cells is characterized by many long microvilli, pedunculated hyaloplasmic protrusions and secretory granules. During hibernation the lumen is filled with secretory material. Myoepithelial cells are arranged among secretory cells or between them and the basal lamina. The short intercalated ducts show similarities with the analogous ducts of the parotid gland. Striated ducts are absent. Excretory ducts are endowed with: a) an inner layer of cuboidal cells characterized by poorly developed cytoplasmic organelles, rare dense granules and a few small microvilli; b) an outer layer of basal cells lying on the basal lamina

    Full Text Available This paper describes the morphology of the tongue, its extrinsic muscles, and the characteristics of lingual papillae in Cuniculus paca. We used fifteen specimens from the Wild Animals Sector of Universidade Estadual Paulista (UNESP. In this species, the tongue is divided into three regions: root, body, and apex. The latter is delimited by the lingual frenum, which has the aspect of fibrous membrane. We also identified a median groove and a prominence on its dorsal surface. The extrinsic tongue muscles are the styloglossus, hyoglossus, genioglossus, geniohyoid, and milohyoid, the latter two are inserted into the hyoid apparatus. As for the presence of lingual papillae, we observed five papillae types in all specimens: filiform, fungiform, vallate, foliate, and conic. The filiform papillae are distributed throughout the apex surface and tongue body. They are caudally inclined throughout the body, until they are modified in the root region and form the conic papillae. The fungiform papillae are distributed in a large amount on the lingual apex, between the filiform papillae. This papilla type has a mushroom-like shape. Only two vallate papillae are located in the caudal portion of the lingual root, and they have an oval shape and are surrounded by a deep groove. The foliate papillae are observed in parallel grooves or slots located in the lateral portion of the tongue, between the vallate papillae and half of the intermolar prominence. In the tongue root, body, and apex we observed keratinized squamous stratified epithelium lining both the lingual papillae and the surface between them.

    Full Text Available Obstructive sleep apnea (OSA patients have increased upper airway muscle activity, including such lingual muscles as the genioglossus (GG, geniohyoid (GH and hyoglossus (HG. This adaptation partially protects their upper airway against obstructions. Rodents are used to study the central neural control of sleep and breathing but they do not naturally exhibit OSA. We investigated whether, in chronically instrumented, behaving rats, disconnecting the GH and HG muscles from the hyoid (H apparatus would result in a compensatory increase of other upper airway muscle activity (EMG and/or other signs of upper airway instability. We first determined that, in intact rats, lingual (GG and intrinsic muscles maintained stable activity levels when quantified based on 2 h-long recordings conducted on days 6 through 22 after instrumentation. We then studied 5 rats in which the tendons connecting the GH and HG muscles to the H apparatus were experimentally severed. When quantified across all recording days, lingual EMG during SWS was modestly but significantly increased in rats with surgically altered upper airway (8.6% ±0.7(SE vs. 6.2% ±0.7 of the mean during wakefulness; p=0.012. Respiratory modulation of lingual EMG occurred mainly during SWS and was similarly infrequent in both groups, and the incidence of sighs and central apneas also was similar. Thus, a weakened action of selected lingual muscles did not produce sleep-disordered breathing but resulted in a relatively elevated activity in other lingual muscles during SWS. These results encourage more extensive surgical manipulations with the aim to obtain a rodent model with collapsible upper airway.

    1990-01-01

    Three different types of lingual papilla were observed by scanning electron microscopy on the dorsal lingual epithelium of the lizard Gekko japonicus. Dome-shaped lingual papillae were located at the apex. Flat, fan-shaped lingual papillae were seen in the widest area of the lingual body. Long, scale-like lingual papillae were arranged on the latero-posterior dorsal surface. At higher magnification, microvilli and microridges were seen to be widely distributed over the surface of the papillae. By light microscopy, the epithelium of the dome-shaped papillae was composed of single, columnar epithelial cells filled with secretory granules. The tip of the epithelium of the fan-shaped and scale-like papillae was composed of stratified squamous epithelial cells without granules. The major part of the epithelium of these two types of papilla, except the tip area, was also composed of single, columnar epithelial cells with secretory granules. By transmission electron microscopy, a nucleus without a defined shape was seen to be located in the basal part of each of the single, columnar epithelial cells. Rough-surfaced endoplasmic reticulum and Golgi apparatus were well developed around the nucleus. The other, major part of the cytoplasm was filled with the spherical secretory granules, a large number of which had very electron-dense cores and moderately electron-dense peripheral regions. In the stratified squamous epithelium, a nucleus, which tended to be condensed on the free-surface side, was located in the center of each cell. Mitochondria, endoplasmic reticulum, and vesicles were observed in the cytoplasm.

    The aim of this study was to compare the anatomical and functional characteristics of the lingual papilla among the Camelidae. For this purpose, tongues of alpaca, guanaco, and llama were used. Numerous long and thin filiform papillae were located in the median groove and none were detected on the rest of the dorsal surface of the lingual apex in alpaca. Secondary papillae originated from the base of some filiform papillae on the ventral surface of alpaca tongue. The bases of some filiform papillae of the lateral surface of the lingual apex were inserted into conspicuous grooves in guanaco and tips of filiform papillae on the dorsal surface of the lingual body were ended by bifurcated apex. On the dorsal surface of the lingual apex of llama, there were no filiform papillae but there were numerous filiform papillae on both the lateral margins of the ventral surface of the lingual apex. Fungiform papillae were distributed randomly on dorsal lingual surface and ventral margins of the tongues of all camelid species. Lenticular papillae were located on the lingual torus and varied in size and topographical distribution for each species. Circumvallate papillae had irregular surfaces in llama and alpaca, and smooth surface in guanaco. In conclusion, llama and alpaca tongues were more similar to each other, and tongues of all camelid species displayed more similarities to those of Bactrian and dromedary camels in comparison with other herbivores and ruminants.

    1997-07-01

    As microneural repair techniques of the sensory mandibular branches enter the third decade of their clinical use, there are but a few long-term investigations into the value of these procedures in the treatment of iatrogenic injury to the lingual (LN), inferior alveolar (IAN) or mental (MN) nerve. To establish the efficacy of microneural repair in lesions of the LN, IAN or MN with loss of continuity, the outcome of sensory recovery was evaluated in a series of 92 patients (LN: direct coaptation n = 39, coaptation + sural nerve grafting n = 23; IAN: direct coaptation n = 11 coaptation + sural nerve grafting n = 10; MN: direct coaptation n = 11). The minimum duration of follow-up was 14 months postoperatively. The persistent sensory deficit was assessed using standardized neurosensory testing and gustometric stimuli. In addition the patients answered a multiple-choice questionnaire containing a list of complaints. To obtain a numeric estimate for interindividual and intergroup comparison the information from clinical measurements and patient reports was condensed into a 'neurological score' and a 'complaint score', respectively. Furthermore, adequate items from both scores were combined to affirm or deny the return of sensory function in terms of protective and discriminative sensation. The overall results show a broad range of variation in the scores, sometimes reflecting severe degrees of persistent sensory impairment. The lowest scores, corresponding to the best regeneration, were found after direct coaptation of the LN, IAN and NM, but even the best results did not provide sensory recovery to a preinjury level. After direct coaptation of LN 69% of the patients exhibited protective sensation and 41% regained discriminative function. In contrast, LN grafting was ensued from restoration of protective function in 39% and discriminative function in 17% of the patients. More striking differences were found between coaptation and grafting of the IAN (IAN coaptation: 91

    The present study describes analytically a rare case in which lingual and facial arteries arise together from an external carotid artery in a common trunk. Thirty anatomic dissections were performed on 15 cadavers in the macroscopic laboratory in the Department of Anatomy of the Medical School of National and Kapodistrian University of Athens. One common trunk from which originated lingual and facial arteries was found. The frequency of this morphology is measured at 6 per cent. The length of the common trunk is measured at 7.3 mm between its origin and its diversion at the facial artery and lingual artery, its diameter at 2.8 mm, its distance from carotid bifurcation at 7.9 mm, and from the superior thyroid artery at 3.3 mm. At the left side of the neck region, facial and lingual arteries arose separately. The anatomic variations of the branching pattern of the external carotid artery and the micrometric values of the vessels are especially important as a result of the numerous operations performed in the neck region that implicate various specialties such as general surgery, head and neck surgery, plastic surgery, and maxillofacial surgery.

    Full Text Available Lingual orthodontics, among both young and adult patients, increased in popularity during last years. The purposes of the present investigation were to evaluate the shear bond strength (SBS values and Adhesive Remnant Index (ARI scores of different lingual brackets compared with a vestibular control bracket. One hundred bovine teeth were extracted and embedded in resin blocks. Four different lingual brackets (Idea, Leone; STB, Ormco; TTR, RMO; 2D, Forestadent and a vestibular control bracket (Victory, 3M were bonded to the bovine enamel surfaces and subsequently shear tested to failure utilizing a Universal Testing Machine. SBS values were measured. A microscopic evaluation was performed to obtain ARI scores. Statistical analysis was performed at a statistically significant level of p < 0.05 to determine significant differences in SBS values and ARI Scores. No statistically significant variations in SBS were reported among the different groups. Conversely, significant differences were shown in ARI scores among the various groups. Clinical relevance of the present study is that orthodontists can expect similar resistance to debonding forces from lingual appliances as with vestibular brackets.

    Full Text Available The tongue represents the morphological diversification in mammals; their papillae have mechanical and gustatory functions in feeding. This study aimed to describe the macroscopic and microscopic morphology of the lingual papillae of rabbits of the Oryctolagus cuniculus species. One used 45 dissected tongues from adult rabbits belonging to the collection of the Laboratory for Education and Research on Wild Animals (LAPASof Universidade Federal de Uberlandia (UFU. For the microscopic identification of the tongue, the optical microscopy and the scanning electron microscopy (SEM techniques were used. The tongue has four papillae types: filiform, fungiform, vallate, and foliate. The filiform papillae have a mechanical function and they present three subtypes: type 1, with a conical shape, from the tongue’s body to the rostral edge of the lingual prominence; type 2, with a sharp shape, in the rostral area of the lingual prominence; and type 3, with a thick and sharp shape, in the caudal area of the lingual prominence. The fungiform papillae have a gustatory function and they’re in the tongue’s body. The foliate papillae are pairs, they have a gustatory function, in the lateral surfaces of the tongue’s body. The vallate papillae are pairs, they have a gustatory function, in the root. On the tongue, one observed a keratinized squamous stratified epithelium, lining the papillae and the regions between them.

    Full Text Available Dental implants placement in the anterior mandible with flap or flapless technique is a routine procedure and is considered to be safe. However, serious life-threatening complications may occur. We report the first case of massive lingual and sublingual haematoma following postextractive implant placement in the anterior mandible with flapless technique. A 45-year-old female patient underwent placement of four immediately postextractive implants in the anterior mandible using flapless technique. During the procedure, the patient referred intense acute pain and worsening sign of airway obstruction, dysphagia, dyspnea, and speech difficulties. Bimanual compression of the mouth floor, lingual surface of the mandible, and submental skin was maintained for approximately 25 minutes in order to stop the bleeding. Computerized tomography highlighted the massive lingual and sublingual haematoma. The symptoms and signs had almost completely resolved in the next 48 hours. The prevention of these complications is mandatory with clinical and CT analyses, in order to highlight mandibular atrophy and to select carefully the correct length and angulation of bone drilling and to keep more attention to the flapless technique considering the elevation of a lingual mucoperiosteal flap to access the mandibular contour intraoperatively and to protect the sublingual soft tissues and vasculature in high risk cases.

    2004-04-01

    A C-lingual retractor was placed on the lingual aspects of the six maxillary anterior teeth in a 24-year-old female patient with a Class II anterior deep-bite malocclusion. The treatment plan consisted of extracting both the upper first premolars and intruding and retracting the upper six anterior teeth. Transpalatal arches were soldered to the upper first and second molar bands and used as an intra-arch anchor unit for upper space closure. Double NiTi closed coil springs were used palatally between the hooks of the C-lingual retractor and the transplantar arches. A high-pull headgear was used for anchorage reinforcement during en masse retraction. It took 14 months to treat this patient. The correct overbite and overjet was obtained by simultaneously intruding and retracting the upper six anterior teeth into their proper positions by C-lingual retractor mechanics, which contributed to an improvement in facial balance. The treatment result was stable 6 months after debonding. The application of this new appliance, consideration in case selection, and sequence of treatment are presented.

    Full Text Available OBJECTIVE: Lingual orthodontics is becoming more popular in dental practice. The purpose of the present investigation was to compare plaque formation on teeth bonded with the same bracket onto buccal or lingual surface, with non-bonded control teeth, via an in vivo growth experiment over a 30-day period. MATERIAL AND METHODS: A randomized controlled trial with split-mouth design was set up enrolling 20 dental students. Within each subject sites with buccal and lingual brackets and control sites were followed. Clinical periodontal parameters (periodontal pocket depth: PPD; bleeding on probing: BOP were recorded at baseline and on days 1, 7 and 30. Microbiological samples were taken from the brackets and the teeth on days 1, 7 and 30 to detect colony-forming units (CFU. Total CFU, streptococci CFU and anaerobe CFU were measured. RESULTS: No significant differences (P>0.05 were found between buccal and lingual brackets in terms of clinical periodontal parameters and microbiological values. Conclusion: Bracket position does not have significant impact on bacterial load and on periodontal parameters.

    The aim of this study was to assess the effect of bracket type on the labiopalatal moments generated by lingual and conventional brackets. Incognito™ lingual brackets (3M Unitek), STb™ lingual brackets (Light Lingual System; ORMCO), In-Ovation L lingual brackets (DENTSPLY GAC), and conventional 0.018 inch slot brackets (Gemini; 3M Unitek) were bonded on identical maxillary acrylic resin models with levelled and aligned teeth. Each model was mounted on the orthodontic measurement and simulation system and 10 0.0175 × 0.0175 TMA wires were used for each bracket type. The wire was ligated with elastomerics into the Incognito, STb, and conventional brackets and each measurement was repeated once after religation. A 15 degrees buccal root torque (+15 degrees) and then a 15 degrees palatal root torque (-15 degrees) were gradually applied to the right central incisor bracket. After each activation, the bracket returned to its initial position and the moments in the sagittal plane were recorded during these rotations of the bracket. One-way analysis of variance with post hoc multiple comparisons (Tukey test at 0.05 error rate) was conducted to assess the effect on bracket type on the generated moments. The magnitude of maximum moment at +15 degrees ranged 8.8, 8.2, 7.1, and 5.8 Nmm for the Incognito, STb, conventional Gemini, and the In-Ovation L brackets, respectively; similar values were recorded at -15 degrees: 8.6, 8.1, 7.0, and 5.7 Nmm, respectively. The recorded differences of maximum moments were statistically significant, except between the Incognito and STb brackets. Additionally, the torque angles were evaluated at which the crown torque fell well below the minimum levels of 5.0 Nmm, as well as the moment/torque ratio at the last part of the activation/deactivation curve, between 10 and 15 degrees. The lowest torque expression was observed at the self-ligating lingual brackets, followed by the conventional brackets. The Incognito and STb lingual brackets

    Full Text Available ABSTRACT Objective: To compare speech performance and levels of oral impairment between two types of lingual brackets. Methods: A parallel-group randomized controlled trial was carried out on patients with Class II, Division 1 malocclusion treated at the University of Hama School of Dentistry in Hama, Syria. A total of 46 participants (mean age: 22.3 ± 2.3 years with maxillary dentoalveolar protrusion were randomly distributed into two groups with 23 patients each (1:1 allocation ratio. Either STb (Ormco or 7th Generation (Ormco lingual brackets were applied. Fricative sound/s/ spectrograms were analyzed directly before intervention (T0, one week following premolar extraction prior to bracket placement (T1, within 24 hours of bracket bonding (T2, one month after (T3, and three months after (T4 bracket placement. Patients′ acceptance was assessed by means of standardized questionnaires. Results: After bracket placement, significant deterioration in articulation was recorded at all assessment times in the 7th Generation group, and up to T3 in the STb group. Significant intergroup differences were detected at T2 and T3. No statistically significant differences were found between the two groups in reported tongue irritation levels, whereas chewing difficulty was significantly higher in the 7th Generation group one month after bracket placement. Conclusions: 7th Generation brackets have more interaction with sound production than STb ones. Although patients in both groups complained of some degree of oral impairment, STb appliances appeared to be more comfortable than the 7th Generation ones, particularly within the first month of treatment.

    The epidemiologic data on oral lesions in native Indians remain unknown in many countries around the world. This paper reports the prevalence and distribution of oral congenital anomalies and pathologic lesions found in a survey of 107 schoolchildren (ages 12 to 17), from two isolated communities in the ethnographic Mazahua area in the State of Mexico. The main entities identified were: pigmented lesions (47.6%), lingual anomalies (17.4%) and developmental tooth alterations (6.9%). The remaining 24.4% of the lesions were gingival inflammatory hyperplasia, partial ankilosis of the tongue, lichen planus, focal epithelial hyperplasia and the double lip. The most frequent localization was lips and tongue. These findings suggest the high prevalence of oral anomalies in this Indian population. Therefore, we suggest that health programs should emphasize the prevention, diagnosis and treatment of these pathologies in Indians groups.

    2011-09-01

    Full Text Available Background: Traumatic ulcer is a common form of ulceration occured in oral cavity caused by mechanical trauma, either acute or chronic, resulting in loss of the entire epithelium. Traumatic ulcer often occurs in children that are usually found on buccal mucosa, labial mucosa of upper and lower lip, lateral tongue, and a variety of areas that may be bitten. To properly diagnose the ulcer, dentists should evaluate the history and clinical description in detail. If the lesion is allegedly accompanied by other infections, such as fungal, bacterial or viral infections, microbiological or serological tests will be required. One of the initial therapy given for fungal infection is nystatin which aimed to support the recovery and repair processes of epithelial tissue in traumatic ulcer case. Purpose: This case report is aimed to emphasize the importance of microbiological examination in suspected cases of ulcer accompanied with traumatic fungal infection. Case: A 12-year-old girl came to the clinic of Pediatric Dentistry, Faculty of Dentistry, University of Indonesia on June 9, 2011 accompanied with her mother. The patient who had a history of geographic tongue came with complaints of injury found in the middle of the tongue. The main diagnosis was ulcer accompanied with traumatic fungal infection based on the results of swab examination. Case management: This traumatic ulcer case was treated with Dental Health Education, oral prophylaxis, as well as prescribing and usage instructions of nystatin. The recovery and repair processes of mucosal epithelium of the tongue then occured after the use of nystatin. Conclusion: It can be concluded that microbiological examination is important to diagnose suspected cases of ulcer accompanied with traumatic fungal infection. The appropriate treatment such as nystatin can be given for traumatic fungal infection.Latar belakang: Ulkus traumatic merupakan bentuk umum dari ulserasi rongga mulut yang terjadi akibat trauma

  12. Lingual CD36 and nutritional status differentially regulate fat preference in obesity-prone and obesity-resistant rats.

    Lingual fatty acid receptors (i.e. CD36) mediate the orosensory perception of fat/fatty acids and may contribute to the susceptibility to develop obesity. The current study tested the hypothesis that fat/fatty acid preference in obesity-prone (OP, Osborne-Mendel) and obesity-resistant (OR, S5B/Pl) rats is mediated by nutritional status and lingual CD36. To determine if nutritional status affected linoleic acid (LA) preference in OP and OR rats, rats were either fasted overnight or fed a high fat diet (60% kcal from fat). In OR rats, fasting increased the preference for higher concentrations of LA (1.0%), while consumption of a high fat diet decreased LA preference. In OP rats, fasting increased the preference for lower concentrations of LA (0.25%), however high fat diet consumption did not alter LA preference. To determine if lingual CD36 mediated the effects of an overnight fast on LA preference, the expression of lingual CD36 mRNA was assessed and the effect of lingual application of CD36 siRNA on LA preference was determined. Fasting increased lingual CD36 mRNA expression in OR rats, but failed to alter lingual CD36 mRNA in OP rats. Following an overnight fast, application of lingual CD36 siRNA led to a decrease in LA preference in OR, but not OP rats. Lingual application of CD36 siRNA was also used to determine if lingual CD36 mediated the intake and preference for a high fat diet in OP and OR rats. CD36 siRNA decreased the preference and intake of high fat diet in OR rats, but not OP rats. The results from this study suggest that the dysregulation of lingual CD36 in OP rats is a potential factor leading to increased fat intake and fat preference and an enhanced susceptibility to develop obesity.

    We examined the distribution of immunofluorescence due to immunostaining of type III collagen, differential interference contrast (DIC) images and images obtained in the transmission mode after toluidine blue staining by laser-scanning microscopy of semi-ultrathin sections of epoxy resin-embedded samples, during morphogenesis of the filiform papillae, keratinization of the lingual epithelium, and myogenesis of the rat tongue. Immunoreactivity specific for type III collagen was distributed widely in the mesenchymal connective tissue in fetuses on day 15 after conception (E15), at which time the lingual epithelium was composed of one or two layers of cuboidal cells and the lingual muscle was barely recognizable. Immunoreactivity specific for type III collagen was clearly detected on the lamina propria in fetuses on E17 and E19, and it was relatively distinct just beneath the lingual epithelium. Immunoreactivity specific for type III collagen was sparsely distributed on the connective tissue around the developing lingual muscle. In fetuses on E19, the epithelium became clearly stratified and squamous. At postnatal stages from newborn (P0) to postnatal day 14 (P14), keratinization of the lingual epithelium advanced gradually with the development of filiform papillae. On P0, myogenesis of the tongue was almost completed. The intensity of the fluorescence immunoreactivity specific for type III collagen at postnatal stages was almost same as that on E19. The immunoreactivity around the fully mature muscle was relatively distinct between P0 and P14. Thus, type III collagen appeared in conjunction with the morphogenesis of filiform papillae and the keratinization of the lingual epithelium as well as in the connective tissue that surrounded the lingual muscle during myogenesis of the rat tongue.

  14. A Method for Direct Fabrication of a Lingual Splint for Management of Pediatric Mandibular Fractures

    Directory of Open Access Journals (Sweden)

    Gerardo P. Romeo, DDS, MD

    2013-10-01

    Full Text Available Summary: Pediatric mandibular fractures have successfully been managed in various ways. The use of a lingual splint is one such option. The typical indirect method for acrylic lingual splint fabrication involves obtaining dental impressions. Dental models are produced from those impressions so that model surgery may be performed. The splint is then made on those models using resin powder and liquid monomer in a wet laboratory and transferred to the patient. Obvious limitations to this technique exist for both patient and operator. We present a technique for direct, intraoperative, fabrication of a splint using commercially available light-cured material that avoids some of the shortcomings of the indirect method. Recommendations are made based on available material safety information.

  15. Procedure for combining a facial porcelain veneer with a metal lingual and occluding surface.

    Bishop, K; Priestley, D

    1996-04-01

    This article describes a procedure for making a crown that combines an all-porcelain facial veneer with a metal lingual and occluding surface. The procedure combines both the conventional lost wax technique and the use of a refractory cast for firing porcelain. The crown retains the advantages of the traditional all-porcelain crown restoration but reduces the risk of damage to the opposing teeth associated with an all-ceramic occluding surface. Furthermore, compared with porcelain, the metal surface allows more control over the occlusal and lingual contours during construction of the crown. Although the construction of the anterior crown is described, the procedure is equally applicable to posterior full-coverage restorations.

    In this phonetic study, productions of the consonant in the stressed syllable position of the word arara as produced by 13 subjects with short and/or anterior lingual frenulum were compared before and after lingual frenectomy. The results from the measurement of the stressed consonant duration and from the identification of the consonant manners of articulation based on the inspection of spectral characteristics are discussed and related to the answers to a perceptual identification test. After surgery, the number of tap productions did not increase, but alveolar productions did. These clinically relevant findings show frenectomy improved tongue mobility, but, as temporal controls were not totally re-established after surgery and 6-month speech therapy sessions, the production of the alveolar tap remained largely unchanged.

    1991-10-01

    The purpose of this study was to investigate the effect of disruption of the auditory feedback channel on lingual vibrotactile thresholds obtained under skilled and unskilled speaking conditions. Each of 22 adults was asked to read an English (skilled) and French (unskilled) passage under conditions of normal and altered auditory feedback. Bilateral presentation of masking noise was utilized to disrupt auditory feedback. Before each of the experimental sessions and immediately following a reading, lingual vibrotactile thresholds were obtained. Analysis indicated that the mean differences in the pre- and postvibrotactile threshold measurements of the skilled auditory disrupted condition varied significantly from the mean differences in the pre- and postvibrotactile threshold measurements of the three other conditions. The role of feedback in the speech production of skilled and unskilled speakers is discussed.

    The present study was aimed to determine the topographic relationship between root apex of the mesially and horizontally impacted mandibular third molar and lingual plate of mandible. The original cone beam computed tomography (CBCT) data of 364 teeth from 223 patients were retrospectively collected and analyzed. The topographic relationship between root apex and lingual plate on cross-sectional CBCT images was classified as non-contact (99), contact (145) and perforation (120). The cross-sectional morphology of lingual plate at the level of root apex was defined as parallel (28), undercut (38), slanted (29) and round (4). The distribution of topographic relationship between root apex and lingual plate significantly associated with gender, impaction depth, root number and lingual plate morphology. Moreover, the average bone thickness of lingual cortex and distance between root apex and the outer surface of lingual plate were 1.02 and 1.39 mm, respectively. Furthermore, multivariate regression analyses identified impaction depth and lingual plate morphology as the risk factors for the contact and perforation subtypes between root apex and lingual plate. Collectively, our findings reveal the topographic proximity of root apex of impacted mandibular third molar to the lingual plate, which might be associated with intraoperative and postoperative complications during tooth extraction.

    Preservation treatments for sleep respiratory disorders, such as the use of a dental device and the technique of nasal continuous positive air pressure, cause discomfort to the patient and are not radical treatments. Therefore, we performed operative therapy instead. Laser midline glossectomy was performed to treat constriction at the root of the tongue in 16 patients diagnosed with sleep apnea syndrome. We also tried lingual tonsil excision using the Harmonic Scalpel in three patients with stenosis at the base of the tongue.

    Several factors have been suggested as possible causes for the development of the swelling and trismus which occur after the surgical removal of impacted third molar teeth. In this investigation, measurements of swelling and trismus were made before and after lower third molar removal by the lingual split technique, in a series of 53 patients. No single cause of these surgical sequelae was identified and the duration and pattern of both swelling and trismus were recorded.

    Mucoceles are the most common lesions of the minor salivary glands and typically appear as a fluctuant, bluish, nontender, submucosal swelling with a normal overlying mucosa. Mucoceles of the glands of Blandin-Nuhn (in the anterior portion of the ventral surface of the tongue) have been considered to be uncommon. This article reports an unusual case of a large extravasation mucocele involving the ventral surface of the tongue, which appeared after a lingual frenectomy.

    Full Text Available Dermoid cysts are epithelial-lined cavities with skin adnexae in the capsule. Only 7% present in the head and neck. Between 2004 and 2013, 4 patients with a lingual dermoid cyst underwent a microsurgical carbon dioxide (CO² laser resection via a median sagittal glossotomy approach. This approach is an elegant technique combining superior visualization, hemostasis, and little postoperative edema with good wound healing, allowing for perfect function preservation of the tongue.

    The aim of this study is to investigate the relative stiffness of straight and mushroom lingual archwires of different diameters, cross sections and alloys, plotting their load/deflection graphs and using a modified three-point bending test. Fujita's mushroom archwires and straight lingual archwires of different diameters, cross sections and alloys were derived by a virtual set-up of an equal malocclusion and were cut at their straight distal portion. These distal portions were tested using a modified three-point bending test by an Instron 4467 dynamometer and the forces, were exerted at 1-mm deflection and were compared on each resulting load/deflection curve by means of ANOVA (p < 0.05). All upper lingual mushroom wires exerted significantly lower forces than the straight wire. Lower mushroom archwires were stiffer than their upper counterparts, which were longer and featured inset bends. In the lower arch, similar levels of forces were recorded for the two types of wire. Load-deflection curves were higher for the straight wires, and stiffness increased proportionally with their diameter. The stiffness of an archwire is a function of its diameter, length and the alloy it is made from. In lower lingual wires, there is little difference in stiffness between mushroom and straight wires, but in upper wires, the straight version is considerably stiffer. The greater bearing effect exhibited by the straight wire in the working and finishing phases makes it less susceptible to bowing effect and therefore preferable for sliding mechanics during en masse retraction, particularly in the upper arch.

    Selecting either buccal or lingual approach for the mandibular third molar surgical extraction has been an intense debate for years. The aim of this observational retrospective study was to classify the molar based on the proximity to the external cortical bone, and analyze the position of inferior alveolar canal (IAC) of each type. Cone-beam CT (CBCT) data of 110 deeply impacted mandibular third molars from 91 consecutive patients were analyzed. A new classification based on the mean deduction value (MD) of buccal-lingual alveolar bone thickness was proposed: MD≥1 mm was classified as buccal position, 1 mm>MD>-1 mm was classified as central position, MD≤-1 mm was classified as lingual position. The study samples were distributed as: buccal position (1.8%) in 2 subjects, central position (10.9%) in 12 and lingual position (87.3%) in 96. Ninety-six molars (87.3%) contacted the IAC. The buccal and inferior IAC course were the most common types in impacted third molar, especially in lingually positioned ones. Our study suggested that amongst deeply impacted mandibular third molars, lingual position occupies the largest proportion, followed by the central, and then the buccal type.

    Background Transient lingual papillitis (TLP) is a common, under-diagnosed, inflammatory hyperplasia of one or multiple fungiform lingual that has an acute onset, and is painful and transient in nature. Material and Methods Eleven cases of TLP were diagnosed based on their clinical features. Information on demographics, clinical characteristics, symptoms, individual or family history of similar lesions, medical history, management and follow-up were extracted from the patients’ records. The English literature was reviewed on TLP differential diagnosis, pathogenesis and management. Results The study group included 8 females and 3 males (age: 10-53 years, mean age 31.7±12.88 years). Seven cases were classified as generalized form of TLP and 4 as localized form. Nine cases were symptomatic. Time to onset ranged from 1 to 14 days. A specific causative factor was not identified in any case and management was symptomatic. Conclusions Although TLP is not considered as a rare entity, available information is limited. Diagnosis is rendered clinically, while biopsy is required in cases with a differential diagnostic dilemma. TLP should be included in the differential diagnosis of acute, painful tongue nodules. Key words:Transient lingual papillitis, fungiform papillary glossitis, tongue, nodules. PMID:28149482

    Taste buds are assemblies of elongated epithelial cells, which are innervated by gustatory nerves that transmit taste information to the brain stem. Taste cells are continuously renewed throughout life via proliferation of epithelial progenitors, but the molecular regulation of this process remains unknown. During embryogenesis, sonic hedgehog (SHH) negatively regulates taste bud patterning, such that inhibition of SHH causes the formation of more and larger taste bud primordia, including in regions of the tongue normally devoid of taste buds. Here, using a Cre-lox system to drive constitutive expression of SHH, we identify the effects of SHH on the lingual epithelium of adult mice. We show that misexpression of SHH transforms lingual epithelial cell fate, such that daughter cells of lingual epithelial progenitors form cell type-replete, onion-shaped taste buds, rather than non-taste, pseudostratified epithelium. These SHH-induced ectopic taste buds are found in regions of the adult tongue previously thought incapable of generating taste organs. The ectopic buds are composed of all taste cell types, including support cells and detectors of sweet, bitter, umami, salt and sour, and recapitulate the molecular differentiation process of endogenous taste buds. In contrast to the well-established nerve dependence of endogenous taste buds, however, ectopic taste buds form independently of both gustatory and somatosensory innervation. As innervation is required for SHH expression by endogenous taste buds, our data suggest that SHH can replace the need for innervation to drive the entire program of taste bud differentiation.

    2001-08-01

    In a prospective study 1,106 impacted mandibular third molars were removed from 687 patients. Clinical, radiographic, and surgical factors were recorded. Postoperatively, we examined the modalities of common sensation in order to assess sensory deficit. The patients were followed up, until complete restitution occurred, or, if the sensibility failed to recover, for at least 6 months. A total of 3.6% of the operated sides demonstrated impairment of labial sensation, and 2.1% of lingual sensation. The vast majority of these disturbances subsided completely during the follow-up period. The incidence of persisting sensory diminution after 6 months was 0.91% for the inferior alveolar, and 0.37% for the lingual nerve. However, the degree of the persisting deficit was slight in most instances. The relationship between the recorded factors and the alteration of sensation was analysed by using the chi2 test. For the inferior alveolar nerve we found the patient's age, the development of the roots, the degree of impaction, and the radiographic position of the nerve canal to be significantly correlated to sensory deficit, as well as the surgical procedures in the depth of the socket and the intraoperative opening of the mandibular canal. As far as the lingual nerve is concerned, general anaesthesia and the individual operator were the main factors predictive of nerve damage.

    Trigeminal nerve injury is a rare, but serious complication of a common procedure, which results in a clinically relevant problem that deserves attention. The emergence of microsurgical repair of trigeminal injury has provided clinicians with treatment options for patients who experience persistent neurosensory deficits. The area of microsurgical repair of trigeminal nerves is now in its adolescence. While great strides have been made in the field since its conception, it is certain that a new generation of oral and maxillofacial surgeons wil bring further progress to the field. In the future, better quantitative sensory testing methods, more accurate imaging modalities, and advances in surgical technique will certainly improve the management of patients with impacted third molars. As clinicians, every day we are confronted with the management of impacted third molars. It is important to evaluate each patient individually with an appropriate clinical and radiographic exam. Every patient should be informed of the relative risks and benefits of third molar removal and a joint decision should be reached between the clinician and patient regarding ideal treatment. However, even with ideal management, complications will occur. If a patient does present with signs of a nerve injury the clinician should carefully document the neurosensory deficit and monitor the patient over time. If the patient exhibits a significant sensory deficit for more than one month a referral for evaluation to a tertiary care center capable of surgical repair of the injury is recommended. The occurrence of a "trigger" or Tinel's like sign is improtant as an indication for surgery but may not occur for a month after injury.

    Full Text Available Abstract Background Supervised toothbrushing programs using fluoride dentifrice have reduced caries increment. However there is no information about the effectiveness of the professional cross-brushing technique within a community intervention. The aim was to assess if the bucco-lingual technique can increase the effectiveness of a school-based supervised toothbrushing program on preventing caries. Methods A randomized double-blinded controlled community intervention trial to be analyzed at an individual level was conducted in a Brazilian low-income fluoridated area. Six preschools were randomly assigned to the test and control groups and 284 five-year-old children presenting at least one permanent molar with emerged/sound occlusal surface participated. In control group, oral health education and dental plaque dying followed by toothbrushing with fluoride dentifrice supervised directly by a dental assistant, was developed four times per year. At the remaining school days the children brushed their teeth under indirect supervising of the teachers. In test group, children also underwent a professional cross-brushing on surfaces of first permanent molar rendered by a specially trained dental assistant five times per year. Enamel and dentin caries were recorded on buccal, occlusal and lingual surfaces of permanent molars during 18-month follow-up. Exposure time of surfaces was calculated and incidence density ratio was estimated using Poisson regression model. Results Difference of 21.6 lesions per 1,000 children between control and test groups was observed. Among boys whose caries risk was higher compared to girls, incidence density was 50% lower in test group (p = 0.016. Conclusion Modified program was effective among the boys. It is licit to project a relevant effect in a larger period suggesting in a broader population substantial reduction of dental care needs. Trial registration ISRCTN18548869.

    Swallowing is a neuromuscular mechanism regulated by many nervous reflex arcs. Persistence of child swallowing at the end of dental eruption is called atypical swallowing (AS). This condition is related to a dysfunction of vertical maxillary growth called open bite. The authors treated this malocclusion with the Enveloppe Linguale Nocturne (ELN), or tongue positioner, created by Dr. Bonnet. The aim of this work is to evaluate the effect of ELN on swallowing and the postural variation obtained by its use. Seven patients affected by AS were evaluated. Surface Electromyography (sEMG) testing was performed on each patient with different tongue positions, and swallowing was evaluated with and without the ELN. A surface Electromyograph (Biopack) with 8 channels was used (4 channels for the right muscles and 4 for the left) on 4 groups of muscles: temporals, masseters (MM), submental (SUB) and sternocleidmastoids. On each patient a postural test using a computerised Postural test (Lizard) was also performed. Statistical analysis was done using the Graph pad Instat 3 both for sEMG activity and for computerised postural analysis. All seven subjects had different results in the sEMG and footrest tests. The sEMG test results indicated that muscle activation and swallowing duration varied greatly with the use of ELN, with a reduction of time of swallow act (p = 0.002) and variation in contraction of muscles. Mean MM activation was higher without ELN than in tests performed with the appliance (p = 0.002). Mean SUB activation was higher with than without ELN (p = 0.0033). ELN has a therapeutic effect on posture too. Computerised postural test without device showed in all patients an alteration of barycentre as well as an elevated oscillatory record (A mmq; V mms). With ELN footrest kilogram difference (p = 0.0110), Oscillatory Area (P = 0.0102) and velocity of oscillation (P = 0.0102) presented a great reduction in respect to patients record without ELN. With ELN the tongue

    In daily orthodontic clinical practice retention is very important, and lingual retainers are part of this challenge. The failure of lingual retainers may be due to many factors. The aim of this study was to assess the retention forces and mechanical behavior of different types of wires matched with different kinds of composites in lingual retainers. A tensile test was performed on cylindrical composite test specimens bonded to orthodontic wires. The specimens were constructed using four different wires: a straight wire (Remanium .016×.022″ Dentaurum), two round twisted wires (Penta One .0215″ Masel, Gold Penta Twisted .0215″ Gold N'braces) and a rectangular braided wire (D-Rect .016×.022″ Ormco); and three composites: two micro-hybrids (Micro-Hybrid Enamel Plus HFO Micerium, and Micro-Hybrid SDR U Dentsply) and a micro-nano-filled composite (Micro-Nano-Filled Transbond LR 3M). The test was performed at a speed of 10mm/min on an Inström device. The wire was fixed with a clamp. The results showed that the bonding between wires and composites in lingual fixed retainers seemed to be lowest for rectangular smooth wires and increased in round twisted and rectangular twisted wires where the bonding was so strong that the maximum tension/bond strength was greater than the ultimate tensile strength of the wire. The highest values were in rectangular twisted wires. Concerning the composites, hybrid composites had the lowest interface bonding values and broke very quickly, while the nano- and micro-composites tolerated stronger forces and displayed higher bonding values. The best results were observed with the golden twisted wire and reached 21.46 MPa with the Transbond composite. With the rectangular braided wire the retention forces were so high that the Enamel Plus composite fractured when the load exceeded 154.6 N/MPa. When the same wire was combined with the Transbond LR either the wire or the composite broke when the force exceeded 240 N. The results of this

    The purpose of this research is to obtain simplified index to evaluate oral hygiene in children. They are divided in two groups: 1) 4-6 years and; 2) 7-10 years. The criteria described by GREEN & VERMILLION, 1960 and 1964 were selected. Calculus was excluded. Once obtained the total data, a simplified of the total index was performed. For the ages 4 to 6 years, we selected labial surfaces of the 54, 61, 82 and the lingual surface of 75. For the mixed dentition we added the labial surface of 26 and the lingual surface of 46. In both dentition, simplified index showed significant correlation with the total index.

    2002-04-05

    The aim of this study was to determine the relative contribution of alpha(1)- and alpha(2)-adrenoceptors involved in sympathetic-evoked vasoconstrictor responses in tissues perfused by the lingual arterial circulation in pentobarbital anesthetized cats. Blood flow in the lingual artery was measured by ultrasonic flowmetry. Laser-Doppler flowmetry was utilized to measure oral tissue vasoconstrictor responses in the maxillary gingiva and from the surface of the tongue. Electrical stimulation of the preganglionic superior cervical sympathetic nerve resulted in frequency-dependent blood flow decreases at all three sites. These responses were stable over time and were uniformly antagonized by administration of phentolamine (0.3 - 3.0 mg kg(-1)). The selective alpha(1)-adrenoceptor antagonist, prazosin (10 - 300 microg kg(-1)), attenuated vasoconstriction in the lingual artery and gingiva, but was ineffective in blocking vasoconstriction in the tongue. Subsequent administration of rauwolscine (300 microg kg(-1)) antagonized remaining vasoconstrictor responses. In contrast, rauwolscine (10 - 300 microg kg(-1)), given alone, blocked evoked vasoconstriction in the tongue, and was without effect on gingival or lingual artery vasoconstrictor responses. Subsequent administration of prazosin (300 microg kg(-1)) largely antagonized remaining neurally elicited responses. These results suggest that neural vasoconstrictor responses in some regional vascular beds in the cat oral cavity are mediated by both alpha(1)- and alpha(2)-adrenoceptors. In contrast, tongue surface vasoconstrictor responses to sympathetic nerve activation appear to be mediated primarily by alpha(2)-adrenoceptors.

    The oral zone reflects the relational modalities of the child: the sensorimotor physiological and psychological behaviour is established according to the development of the facial sphere and its aero-digestive crossroads. In the baby, the mandibular equilibrium and position and the dimensions of the lower part of the face essentially depend upon praxic activities, which drive the mandibular and hyoid displacements. During the period of immaturity, the lingual area is brought into movement with each "sucking-swallowing" action that characterises breast-feeding: the mandibulo-hyoid swing is subordinate to the pharyngo-lingual complex. The analysis of this psycho-motor behaviour reveals imperfect and upsetting "mimics" that modify the balance of the jaw and of the hyo-lingual area during swallowing, which is the second phase of the reassurance breast-feed. The lingual ptosis causes congestion of the airways. These lax children, with a receding chin, are deformed by their oral habits. The clinical picture evidences the constitutional hyperlaxity by examining the parental group -the same facial dystrophies, the same habits resulting in various disorders of general or cervical statics. At the level of the temporomandibular joint, the dysfunction is also accompanied by claudication by mandibulo-hyo-lingual tipping. The general and cervical statics of the baby are thus affected in the course of sleep. It is during paradoxical sleep that the baby's head tips on to the thorax, due to the resultant atonia of the neck muscles. The head, insufficiently supported on its cervical pillar accentuates the asphyxial mechanism provoked by the tipping of the lingual area on the epiglottis.(ABSTRACT TRUNCATED AT 250 WORDS)

    During the 20th century functional appliances evolved from night time wear to more flexible appliances for increased day time wear to full time wear with Twin Block appliances. The current trend is towards fixed functional appliances and this paper introduces the Fixed Twin Block, bonded to the teeth to eliminate problems of compliance in functional therapy. TransForce lingual appliances are pre-activated and may be used in first phase treatment for sagittal and transverse arch development. Alternatively they may be integrated with fixed appliances at any stage of treatment.

    OBJECTIVE: Micro-neurosurgical repair is considered in permanent nerve damage but the outcome is unpredictable. We examined if histopathologic parameters of traumatic neuromas have a prognostic value for recovery in relation to lingual nerve micro-neurosurgery.

    The purpose of this study was to describe an unusual case of a lingual schwannoma associated with a mixed connective tissue disease (MCTD). A case report. A lingual schwannoma with loss of lingual sensitivity and slightly increased size in an 18-year-old patient with MCTD was correctly diagnosed through a biopsy and no reoccurrence was observed one year after the surgical removal of the tumor and sensitivity returned 3 months after surgery. This case was considered uncommon, making the clinical diagnosis challenging in view of the diversity of possibilities for its differential diagnosis, thus showing the importance of a biopsy to confirm the diagnosis and long term follow up in such cases.

    This report describes the use of miniscrew-assisted customized lingual fixed appliances in a patient with severe skeletal Class II malocclusion. The patient was a 12-year-old Chinese girl with the chief complaint of protrusive lips and anterior teeth. Her diagnosis included a skeletal Class II relationship with maxillary protrusion, a backward-rotated mandible, a full Angle Class II molar relationship, and severe deep overjet and overbite. Four premolars were extracted, and miniscrew anchorage was placed in the maxillary posterior lingual segment to provide maximum anchorage and to achieve vertical control of the intruding molars. The customized lingual fixed appliance and temporary anchorage devices created a smooth and invisible treatment progress, resulting ultimately in a well-aligned dentition with ideal intercuspation and a dramatically improved profile. The 3-year follow-up examination indicated that the excellent treatment outcome was stable. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

    Incorrectly produced speech sounds, the presence of dentofacial alterations and acquired functional adaptations may be due to a short and inadequate lingual frenum. When frenectomy is indicated, it should be performed as early as possible to prevent functional alterations. This study presents a literature review on correct lingual positioning in relation to orthodontic and phonetic function as well as an assessment of 15 patients who underwent frenectomy utilizing the carbon dioxide laser. The results demonstrated that this technique is safe, effective and perfect for use in young children and can be performed in an outpatient unit.

    This paper reported one case with severe periodontal lesions caused by malformed lingual groove treated by guided tissue regeneration. The periodontal lesion was exposed palatally after the tooth had been treated with root canal therapy, the alveolar bone and the root surface was prepared, an unabsorbable member of e-PTFE was placed into the wound,and removed after 4 weeks, the patient was followed up for 3 years. The lesion recovered well three years after the operation, all of the periodontal tissue was in a healthy condition. It is advisable that guided periodontal tissue regeneration can be used as a new method to treat periodontal destruction induced by malformed lingual groove.

    One of the crucial factors in the success of guided bone regeneration procedures is the correct management of the soft tissues. This allows for stable primary wound closure without tension, which can result in premature exposure of the augmentation area, jeopardizing the final outcome. The use of vertical and periosteal incisions to passivate buccal and lingual flaps in the posterior mandible is often limited by anatomical factors. This paper reports on a series of 69 consecutive cases introducing a novel surgical technique to release and advance the lingual flap coronally in a safe and predictable manner.

    To determine whether the reduction of the alveolar ridge that occurs following tooth extraction and implant placement is influenced by the size of the hard tissue walls of the socket. Six beagle dogs were used. The third premolar and first molar in both quadrants of the mandible were used. Mucoperiostal flaps were elevated and the distal roots were removed. Implants were installed in the fresh extraction socket in one side of the mandible. The flaps were replaced to allow a semi-submerged healing. The procedure was repeated in the contra later side of the mandible after 2 months. The animals were sacrificed 1 month after the final implant installation. The mandibles were dissected, and each implant site was removed and processed for ground sectioning. Marked hard tissue alterations occurred during healing following tooth extraction and implant installation in the socket. The marginal gap that was present between the implant and the walls of the socket at implantation disappeared as a result of bone fill and resorption of the bone crest. The modeling in the marginal defect region was accompanied by marked attenuation of the dimensions of both the delicate buccal and the wider lingual bone wall. Bone loss at molar sites was more pronounced than at the premolar locations. Implant placement failed to preserve the hard tissue dimension of the ridge following tooth extraction. The buccal as well as the lingual bone walls were resorbed. At the buccal aspect, this resulted in some marginal loss of osseointegration.

    AIM: To evaluate the effect of posterior lingual lidocaine swab on patient tolerance to esophagogastroduodenoscopy, the ease of performance of the procedure, and to determine if such use will reduce the need for intravenous sedation. METHODS: Eighty patients undergoing diagnostic esophagogastroduodenoscopy in a tertiary care medical center were randomized to either lidocaine swab or spray. Intravenous meperidine and midazolam were given as needed during the procedure. RESULTS: Patients in the lidocaine swab group (SWG) tolerated the procedure better than those in the spray group (SPG) with a median tolerability score of 2 (1, 4) compared to 4 (2, 5) (P < 0.01). The endoscopists encountered less difficulty performing the procedures in the SWG with lower median difficulty scores of 1 (1, 5) compared to 4 (1, 5) in the SPG (P < 0.01). In addition, the need for intravenous sedation was also lower in the SWG compared to the SPG with fewer patients requiring intravenous sedation (13/40 patients vs 38/40 patients, respectively, P < 0.01). The patients in the SWG were more satisfied with the mode of local anesthesia they received as compared to the SPG. In addition, the endoscopists were happier with the use of lidocaine swab. CONCLUSION: The use of a posterior lingual lidocaine swab in esophagogastroduodenoscopy improves patient comfort and tolerance and endoscopist satisfaction and decreases the need for intravenous sedation.

    Due to the scarcity of giant pandas, there are few descriptions of their morphology and even fewer of their microscopic anatomy and the ultrastructure of their organs. In this study of the complete tongue of an adult male giant panda, we describe the morphology of its lingual surface, the different types of papillae, their characteristics and topographic distribution. It was seen that there are four main types of lingual papillae: filiform, conical, fungiform and vallate. There was no sign of foliate papillae, tuberculum intermolare or sublingua. Papilla distribution was not limited to the dorsum of the tongue, but was also seen on the anterior and ventral surfaces of the tongue. In the anterior third of the midline there is a smooth area with no papillae at all. Morphology of the microgrooves and pores is similar to that observed in other mammals. The papillae share characteristics encountered in Carnivora and herbivorous species of mammals. A narrow bamboo-based diet and specialized manner of eating have together resulted in modification of the tongue of a carnivoran, giving it some characteristics typical of an herbivore.

    2007-01-01

    Using histological, morphometric and quantitative histoenzymological methods, the changes of lingual epithelium were studied in 40 outbred albino mice after 5 intraperitoneal injections of 100 micrograms of hydra peptide morphogen (HPM) per 1 kg of body weight. Administration of HPM was found to increase the total thickness of epithelial layer on the dorsal tongue surface in the interpapillary regions, while in the area of filiform papillae these changes were not significant. On the ventral tongue surface HPM induced a marked increase of total thickness of the epithelial layer as compared to that in control animals. Mitotic activity was increased in the epithelium covering the ventral surface and in the interpapillary regions on the dorsal tongue surface. Histoenzymologic study which involved the demonstration of NADH-diaphorase, succinate- and lactate-dehydrogenase (LDH) activities, followed by a cytophotometric evaluation of enzyme activity, has shown a stimulatory effect of HPM on the activity of all the enzymes studied, which was most pronounced in respect to LDH and was maximally expressed on the dorsal tongue surface. These findings collectively suggest that HPM exerts a stimulatory effect on proliferation activity and metabolism of lingual epithelium, which is differentially expressed in its variuoe topographical zones.

    The blue-tongue lizard (Tiliqua scincoides) is a variety of large skink common throughout Australia. There are seven species of Tiliqua and all of them have long bodies, short limbs and short and robust tails. T. scincoides occurs in a wide range of habitats; its diet is omnivorous. When threatened, it opens the mouth and protrudes its characteristic large fleshy cobalt blue tongue. It is currently found as a popular species and also as a pet animal in the European countries. No data are available in literature about the morphology of the tongue of T. scincoides; therefore, the aim of the present study was to investigate by means of scanning electron microscopy and light microscopy, the anatomy of the dorsal lingual surface. Our results demonstrate the presence of a tongue tip with a smooth surface without papillae. The foretongue was characterized by a stratified epithelium with foliate-like papillae and deep inter-papillar spaces in the middle part and cylindrical papillae with a flat surface in the lateral parts. All the posterior area of the tongue was characterized by more compacted papillae and the inter-papillar spaces were very narrow. Light microscopy showed the presence of melanin throughout the tongue. No taste buds were recognized on the lingual dorsal surface. Therefore, the papillae probably have a mechanical function showing an important role in the swallowing phase. The morphology of the tongue surface can be correlated to the diet and, different roles, as in other examined species, can be hypothesized for different areas.

    Lingual keratinized epithelial cells, which constitute the filiform papillae of the tongue, have one of the most rapid tissue turnover rates in the mammalian body and are thought to be the source of squamous cell carcinoma of the tongue. However, the mechanism of tissue maintenance and regeneration is largely unknown for these cells. Here, we show that stem cells positive for Bmi1, keratin 14 and keratin 5 are present in the base but not at the very bottom of the interpapillary pit (observed most frequently in the second or third layer (position +2 or +3) from the basal cells). Using a multicolour lineage tracing method, we demonstrated that one stem cell per interpapillary pit survives long-term. The cells were shown to be unipotent stem cells for keratinized epithelial cells but not for taste bud cells, and were found to usually be in a slow-growing or resting state; however, on irradiation-induced injury, the cells rapidly entered the cell cycle and regenerated tongue epithelium. The elimination of Bmi1-positive stem cells significantly suppressed the regeneration. Taken together, these results suggest that the stem cells identified in this study are important for tissue maintenance and regeneration of the lingual epithelium.

    Cochlear Implant is a sensory prosthesis capable of restoring hearing in patients with severe or profound bilateral sensorineural hearing loss. To evaluate if there is a better side to be implanted in post-lingual patients. Retrospective longitudinal study. Participants were 40 subjects, of both sex, mean age of 47 years, with post-lingual hearing loss, users of unilateral cochlear implant for more than 12 months and less than 24 months, with asymmetric auditor reserve between the ears (difference of 10dBNA, In at least one of the frequencies with a response, between the ears), divided into two groups. Group A was composed of individuals with cochlear implant in the ear with better auditory reserve and Group B with auditory reserve lower in relation to the contralateral side. There was no statistical difference for the tonal auditory threshold before and after cochlear implant. A better speech perception in pre-cochlear implant tests was present in B (20%), but the final results are similar in both groups. The cochlear implant in the ear with the worst auditory residue favors a bimodal hearing, which would allow the binaural summation, without compromising the improvement of the audiometric threshold and the speech perception.

    Aravind, M; Shivaprakash, G; Ramesh, G C

    2013-01-01

    The aim of this report is to illustrate treatment mechanics for torque control in lingual mechanotherapy using a lever arm and transpalatal arch (TPA) tab system during en masse retraction of anterior teeth. An 18-year-old female with bimaxillary dentoalveolar proclination with crowding was treated with a lever arm-TPA tab system. The retraction tabs bent into the TPA placed across the maxillary second molars were used as anchorage. The retraction force on the maxillary anterior teeth was applied using lever arm hooks soldered between the lateral incisors and canines on a lingual mushroom archwire. By applying a retraction force to the lever arm hooks, the maxillary anterior teeth experienced greater palatal root movement as compared to the conventional retraction forces applied at the crown level. The tabs, placed high in the TPA, produced a distal tipping moment on the maxillary second molars, reinforcing their anchorage. The retraction force applied to the long lever arm hooks from the TPA tabs at the level of center of resistance (CRes) of anterior and posterior teeth is advantageous mainly in two aspects. First, it reinforces the anchorage, and second, it favors the palatal root movement of anterior teeth, thus obtaining better control over the torque during en masse retraction.

    This study aimed to evaluate the effect of lingual gauze swab placement on pulse oximeter readings in anaesthetised dogs and cats. Following anaesthetic induction, the following pulse oximeter probe configurations were performed: no gauze swab (control), placement of a gauze swab between the tongue and the probe, placement of different thicknesses of gauze swab, placement of red cotton fabric, placement of a sheet of white paper and placement of the probe and gauze swab on different locations on the tongue. Oxygen saturation (SpO2) and peripheral perfusion index (PI) were recorded. Placement of a gauze swab between the pulse oximeter probe and the tongue in anaesthetised dogs and cats resulted in significantly higher SpO2 values compared with the control group. In dogs, PI values were significantly higher than the control in all groups except the quarter thickness swab group. In cats, PI was significantly higher in the double thickness swab and white paper groups compared with the control. Cats had significantly higher SpO2 and lower PI values than dogs. The authors propose that increased contact pressure is responsible for significantly higher SpO2 and PI readings with the use of a lingual gauze swab resulting from changes in transmural pressure and arterial compliance.

    Mucocele is an oral soft tissue cyst caused by the disturbance of saliva flow. Mucocele is widely observed in child patients and recurrence is high. The objective of this study was to clarify the effect of CO II laser irradiation in the case of mucocele. A CO II laser was used on 45 subjects, aged between 0 to 15 years, having mucocele on lip, lingual, or buccal mucosa. Our procedure in using CO II laser was not to vaporize the mucocele but to remove the whole mucocele mass. The border of mucocele was firstly incised by laser following defocusly ablating the root or body of mucocele separating from sorrounding tissue. As a result, mucocele was easily and completely removed without breaking the wall of mucocele. None of the cases required suturing. The results were as follows. 1. The mucocele of lip or lingual mucosa with a rich blood supply, was efficiently removed, without bleeding, giving a clear operative field during the operation. 2. The surgery itself was simple and less time-consuming. 3. After two or three weeks the wound was completely healed without almost any discomfort in all patients 4. Wound contraction and scarring were decreased or eliminated. 5. The reoccurrence of mucocele was not seen, except only in one case of lingual mucocele. In conclusion the use of CO II laser proved to be a very safe and effective mode for the removal of mucocele, especially in small children.

    Cine MRI has become a useful tool in the evaluation of patients with persistent obstructive sleep apnea (OSA) despite previous surgical intervention and in patients with underlying conditions that render them susceptible to multilevel airway obstruction. Findings on cine MRI studies have also increased our understanding of the mechanisms and anatomic causes of OSA in children. To compare lingual tonsil size between children with OSA and a group of normal controls. In addition, a subanalysis was made of the group of children with OSA comparing lingual tonsils between children with and without underlying Down syndrome. Children with persistent OSA despite previous palatine tonsillectomy and adenoidectomy and controls without OSA underwent MR imaging with sagittal fast spin echo inversion-recovery images, and lingual tonsils were categorized as nonperceptible at imaging or present and measurable. When present, lingual tonsils were measured in the maximum anterior-posterior diameter. If lingual tonsils were greater than 10 mm in diameter and abutting both the posterior border of the tongue and the posterior pharyngeal wall, they were considered markedly enlarged. There were statistically significant differences between the OSA and control groups for the presence vs. nonvisualization of lingual tonsils (OSA 33% vs. control 0%, P=0.0001) and mean diameter of the lingual tonsils (OSA 9.50 mm vs. control 0.0 mm, P=0.00001). Within the OSA group, there were statistically significant differences between children with and without Down syndrome for the three lingual tonsil width categories (P=0.0070) and occurrence of markedly enlarged lingual tonsils (with Down syndrome 35% vs. without Down syndrome 3%, P=0.0035). Enlargement of the lingual tonsils is relatively common in children with persistent obstructive sleep apnea after palatine tonsillectomy and adenoidectomy. This is particularly true in patients with Down syndrome. (orig.)

    Full Text Available Bilingual dictionaries for technical terms such as biomedical terms are an important resource for machine translation systems as well as for humans who would like to understand a concept described in a foreign language. Often a biomedical term is first proposed in English and later it is manually translated to other languages. Despite the fact that there are large monolingual lexicons of biomedical terms, only a fraction of those term lexicons are translated to other languages. Manually compiling large-scale bilingual dictionaries for technical domains is a challenging task because it is difficult to find a sufficiently large number of bilingual experts. We propose a cross-lingual similarity measure for detecting most similar translation candidates for a biomedical term specified in one language (source from another language (target. Specifically, a biomedical term in a language is represented using two types of features: (a intrinsic features that consist of character n-grams extracted from the term under consideration, and (b extrinsic features that consist of unigrams and bigrams extracted from the contextual windows surrounding the term under consideration. We propose a cross-lingual similarity measure using each of those feature types. First, to reduce the dimensionality of the feature space in each language, we propose prototype vector projection (PVP--a non-negative lower-dimensional vector projection method.

    To assess the anatomy of the mandibular lingual vascular canals with the use of computed tomography (CT). Seventy consecutive patients underwent preimplantation CT of the mandible. CT images were obtained on axial plane by using a bone reconstruction algorithm and then processed with dedicated software (Dentascan). The number of lingual vascular canals, the diameter of their entrance foramina and the distance of the foramina from the symphysis menti and from the lower edge of the mandible were measured in each patient. The median superior canal (MSC), the median inferior canal (MIC), the lateral mesial canals (LMC) and the lateral distal canals (LDC) were evaluated separately. 0 to 5 canals were found in each patient. The MSC was found to be present in 98.6% of cases; the mean diameter of the entrance foramen was 0.85+/-0.28 mm located adjacent the symphysis menti and 11.3+/-2.6 mm from the inferior margin of the mandible. The MIC was found to be present in 32.9% of cases; the mean diameter of the entrance foramen was 0.58+/-0.21 mm located adjacent the symphysis menti and 5.5+/-2.2 mm from the inferior margin of the mandible. LMCs were found to be present in 38.6% of cases; the mean diameter of their entrance foramina was 0.60+/-0.24 mm located 5.1+/-2.5 mm from the symphysis menti and 6.3+/-3.2 mm from the inferior margin of the mandible. LDCs were found to be present in 48.6% of the patients; the mean diameter of their entrance foramina was 0.58+/-0.19 mm located 19.3+/-7.3 mm from the symphysis menti and 6.6+/-5.4 mm from the inferior margin of mandible. Dental CT detects the lingual vascular canals of the mandible in a high percentage of subjects and allows a good demonstration of their number, location and entrance foramen diameter. The evaluation of these canals is important in the preoperative planning of dental implants or in the planning of dental surgery in general so as to avoid bleeding due to damage of the vessels present in these canals.

    Despite the strong need for the establishment of a lingual epithelial cell culture system, a simple and convenient culture method has not yet been established. Here, we report the establishment of a novel lingual epithelium organoid culture system using a three-dimensional matrix and growth factors. Histological analyses showed that the generated organoids had both a stratified squamous epithelial cell layer and a stratum corneum. Very recently, we showed via a multicolor lineage tracing method that Bmi1-positive stem cells exist at the base of the epithelial basal layer in the interpapillary pit. Using our new culture system, we found that organoids could be generated by single Bmi1-positive stem cells and that in the established organoids, multiple Bmi1-positive stem cells were generated at the outermost layer. Moreover, we observed that organoids harvested at an early point in culture could be engrafted and maturate in the tongue of recipient mice and that the organoids generated from carcinogen-treated mice had an abnormal morphology. Thus, this culture system presents valuable settings for studying not only the regulatory mechanisms of lingual epithelium but also lingual regeneration and carcinogenesis.

    To clarify variations of vascular distribution around the mandibular anterior tooth lingual region, an area in which vascular injuries have often been reported during dental implant surgery. The reasons for such injuries in this region are discussed from an anatomical perspective. Anatomical dissections were performed on 100 sides of 50 cadavers used for anatomy education. Ten sides of 5 cadavers were injected intravascularly with methyl methacrylate, and penetration of the mandible was closely evaluated. In the mandibular anterior tooth lingual region, both the sublingual and submental arteries showed various distribution patterns. Distal branches basically penetrated the bone. In the mandibular anterior tooth lingual region, the sublingual and submental arteries traveled from the vicinity of the mylohyoid muscle attachment along the bone surface in an anterosuperior direction. Many of these blood vessels penetrated the alveolar mucosa in the anterior tooth region, and many distal branches of the vessels also finally penetrated the bone. This seems to explain why many vascular injuries are encountered around the mandibular anterior tooth lingual region during implant surgery.

  20. Japanese/English Blog Distillation and Cross-Lingual Blog Analysis with Multilingual Wikipedia Entries as Fundamental Knowledge Source

    Science.gov (United States)

    Nakasaki, Hiroyuki; Kawaba, Mariko; Yokomoto, Daisuke; Utsuro, Takehito; Fukuhara, Tomohiro

    The overall goal of this paper is to cross-lingually analyze multilingual blogs collected with a topic keyword. The framework of collecting multilingual blogs with a topic keyword is designed as the blog feed retrieval procedure. In this paper, we take an approach of collecting blog feeds rather than blog posts, mainly because we regard the former as a larger information unit in the blogosphere and prefer it as the information source for cross-lingual blog analysis. In the blog feed retrieval procedure, we also regard Wikipedia as a large scale ontological knowledge base for conceptually indexing the blogosphere. The underlying motivation of employing Wikipedia is in linking a knowledge base of well known facts and relatively neutral opinions with rather raw, user generated media like blogs, which include less well known facts and much more radical opinions. In our framework, first, in order to collect candidates of blog feeds for a given query, we use existing Web search engine APIs, which return a ranked list of blog posts, given a topic keyword. Next, we re-rank the list of blog feeds according to the number of hits of the topic keyword as well as closely related terms extracted from the Wikipedia entry in each blog feed. We compare the proposed blog feed retrieval method to existing Web search engine APIs and achieve significant improvement. We then apply the proposed blog distillation framework to the task of cross-lingually analyzing multilingual blogs collected with a topic keyword. Here, we cross-lingually and cross-culturally compare less well known facts and opinions that are closely related to a given topic. Results of cross-lingual blog analysis support the effectiveness of the proposed framework.

    Full Text Available As edentulous mandible become atrophic, a denture bearing area will also be reduced. Difficulty in the removable prosthesis rehabilitation will be present as well. The purpose of this paper reports an innovative surgical technique to cope a problem of unstable complete lower denture due to bone atrophy and resulted of vertical height reduction of the anterior region of the mandible necessary for denture retention. Vertical advancement of the lower jaw using lingual bone split pedicle onlay graft technique in the anterior region of the mandible and followed by secondary epithelization vestibuloplasty in achieving the vertical height dimension. The surgery was achieved satisfactorily as the vertical dimension of the mandible anterior region had increased and the denture seated more stable comparing with the previous denture worn by the patient. It concluded that the surgery was achieved with a great result as the vertical height of the anterior region of the mandible had increased positively therefore lead the denture seated more stable.

    We describe the strategy of physiological positioning, which we regard as a new alternative treatment to conventional orthognathic operations, and treated 18 patients with skeletal mandibular prognathism using it. The positions of SNB, FMA, and Me were measured postoperatively to assess skeletal stability, changes in the angle and perpendicular length of the upper and lower central incisors were measured to assess dental stability, and we confirmed that both skeletal and dental stability were excellent. The width to which the jaw could be opened recovered early, and we saw only one case of disorder of the temporomandibular joint. Short lingual osteotomy with physiological positioning is an effective new approach to the treatment of deformities of the mandible.

    The inferior alveolar nerve (IAN) and lingual (LN) are susceptible to iatrogenic surgical damage. Systematically review recent clinical evidence regarding IAN/LN repair methods and to develop updated guidelines for managing injury. Recent publications on IAN/LN microsurgical repair from Medline, Embase and Cochrane Library databases were screened by title/abstract. Main texts were appraised for exclusion criteria: no treatment performed or results provided, poor/lacking procedural description, cohort deficit shows no improvement 90 days post-diagnosis. Nerve transection diagnosed intra-operatively should be repaired in situ; minor nerve injury repair can be delayed. No consensus exists regarding optimal methods and timing for IAN/LN repair. We suggest a schematic guideline for treating IAN/LN injury, based on the most current evidence. We acknowledge that additional RCTs are required to provide definitive confirmation of optimal treatment approaches.

    Transient lingual papillitis is a benign condition characterized by the inflammation of one or more fungiform papillae on the dorsolateral tongue. Although it is a common condition that affects more than half of the population, few cases have been reported in the dermatological literature. Therefore, it is a condition uncommonly recognized by dermatologists though it has a distinct clinical presentation that may be easily diagnosed by clinicians familiar with the entity. We report an interesting case of transient lingual papillitis in a 27 year-old healthy woman following the consumption of the hard candy, Atomic Fireball. We describe treatment and resolution of the condition, and its recurrence following re-exposure to the identified culprit. This report further reviews the literature to illustrate the clinical manifestations, etiology, differential diagnosis, course, and treatment of this condition.

    2006-12-01

    It has been suggested that different etiologies of lingual nerve damage in the third molar area will produce a different clinical and histologic appearance in the nerve. If the clinical and histologic pictures were different, it could result in different treatments being recommended. Eight preserved cadavers (16 lingual nerves) were used for this study. As far as possible, the nerves were left in situ and damaged in a way that could be envisaged during third molar surgery. In each case, the damaged sections of nerve were photographed, resected, embedded in paraffin wax, sectioned in 5 mum sections, stained with hematoxylin-eosin, and examined histologically. The scalpel clinically produced a clean wound with sharply defined edges; this was confirmed histologically with minimal disruption to the fascicles. The 702 fissure bur produced a ragged stretch-type injury clinically, and histologically this was confirmed with an irregular-edged border to the lesion and stretching and internal damage to the fascicles immediately adjacent to the wound. The crush injury clinically caused considerable apparent damage to the nerve, which was confirmed histologically with crushing and disruption of the fascicles and reduction to approximately 25% of their preinjury thickness. The stretch injury clinically showed no damage, but histologically showed irregular internal disruption of the fascicles over the whole area subject to stretching movements. It does appear that different modalities in nerve injury produce a different type of injury both clinically and histologically. This information has implications for both natural clinical recovery and the indications for surgical intervention. Clinical recovery may occur best with close approximation of a sharp scalpel-type wound or excision of a crushed area of nerve with reapproximation of the nerve endings, but a ragged wound caused by a fissure bur may require excision back to healthy nerve with subsequent reapproximation, whereas

    60 patients were researched for the purpose of comparable estimation of local homeostasis' indexes and acid-based balance in the oral cavity. They were divided into three groups: patients with parodontitis and diabetes (second type), patients with parodontitis only and practically healthy patients. Their blood was analyzed for glucose and glycerinated hemoglobin, mixed saliva--for the presence of glucose with use of the new method, salivation speed, bacterial composition of lingual plaque and parodontal pockets, pH of mixed of saliva, pH of lingual plaque and gingival liquor, carbamyde pH-test index. Patients with diabetes showed an increase of glucose concentration in the saliva which correlates with similar index of blood, as well as abrupt reduction of salivation and disorder of micrbiocenosis. An increase of acidosis in oral cavity and parodontal tissues, an increase of the activity of ureazpositive micro flora in lingual plaque were discovered. For express diagnosis of disbacteriosis in oral cavity the authors recommend to use indexes of local carbamyde pH-test on the tip of tongue and the new non-invasive hyperglycemia diagnosis method.

    The goal of this study was to evaluate the effects of urethral reconstruction with a three-dimensional (3D) porous bacterial cellulose (BC) scaffold seeded with lingual keratinocytes in a rabbit model. A novel 3D porous BC scaffold was prepared by gelatin sponge interfering in the BC fermentation process. Rabbit lingual keratinocytes were isolated, expanded, and seeded onto 3D porous BC. BC alone (group 1, N  =  10), 3D porous BC alone (group 2, N  =  10), and 3D porous BC seeded with lingual keratinocytes (group 3, N  =  10) were used to repair rabbit ventral urethral defects (2.0   ×   0.8 cm). Scanning electron microscopy revealed that BC consisted of a compact laminate while 3D porous BC was composed of a porous sheet buttressed by a dense outer layer. The average pore diameter and porosity of the 3D porous BC were 4.23   ±   1.14 μm and 67.00   ±   6.80%, respectively. At 3 months postoperatively, macroscopic examinations and retrograde urethrograms of urethras revealed that all urethras maintained wide calibers in group 3. Strictures were found in all rabbits in groups 1 and 2. Histologically, at 1 month postoperatively, intact epithelium occurred in group 3, and discontinued epithelium was found in groups 1 and 2. However, groups 2 and 3 exhibited similar epithelial regeneration, which was superior to that of group 1 at 3 months (p  3D porous BC seeded with lingual keratinocytes enhanced urethral tissue regeneration. 3D porous BC could potentially be used as an optimized scaffold for urethral reconstruction.

    Figueiredo, Rui; Gay-Escoda, Cosme

    2014-01-01

    Lingual mandibular bone defects, also known as Stafne bone cavity (SC), are unilateral asymptomatic radiolucencies, generally seen in the mandibular angle, below the inferior alveolar canal. Although panoramic radiographies normally offer enough information to make a correct diagnosis, additional studies are often required, especially in atypical cases. The present report describes an atypical presentation of a Stafne’s bone cavity in a 78 years-old male patient. In this particular case, an asymptomatic and radiolucid lesion was observed during a routine dental examination. The computed tomography (CT) showed an involvement of both lingual and buccal mandibular plates producing a tunnel-like lesion. No history of mandibular trauma or surgery was refered. An additional magnetic resonance imaging (MRI) was made to discard submandibular gland pathology and to confirm the diagnosis. Since SC is asymptomatic and nonprogressive, a conservative approach based in clinical and radiological follow-ups was considered to be the most suitable treatment option. Key words:Stafne bone cavity, lingual mandibular bone defect, case report. PMID:24596643

    To evaluate the stress distribution of the cervical-defected incisor with labial or lingual endodontic access with finite element analysis (FEA), and to explore the advantage of resistance in labial endodontic access. 3-D finite element models of upper cervical-defected incisor were established using cone-beam CT (CBCT), Mimics Catia, and Ansys software. The subjects were categorized according to the two endodontic accesses and three restorative ways, which were composite resin, glass fiber-reinforced composite resin and glass fiber-reinforced post-crown. All the models were loaded.The von Mises stress values and distribution were recorded and analyzed with Ansys 10.0 software. In this study, direct composite resin restoration showed no significant difference between the labial and lingual access. In glass fiber-reinforced composite resin, labial access could transfer the stress concentration area. It could reduce the incidence of fracture of the cervical lesion but increase the incidence of root fracture. Post-crown restoration could obviously reduce the incidence of fracture of the cervical lesion. When the cervical-defected incisor is restored with composite resin, labial and lingual accesses can be considered. Labial access with glass fiber-reinforced composite resin or post-crown restoration is a good choice.

    2013-04-01

    This study investigated the exact intra-alveolar aetiology of a panoramic high-risk sign, darkening of the third molar roots. 83 mandibular third molar surgical removals demonstrating dark bands on the third molar roots in preoperative radiographs were included in this prospective study. Exposure of the inferior alveolar nerve (IAN), the root morphology of the third molar (e.g. groove or hook) and the integrity of the mandibular canal or lingual cortical wall were observed. Differences between single (increased radiolucency alone) and multiple darkening cases (increased radiolucency with accompanying 'high risk' signs) and between IAN exposure and groove formation were analysed. In 38 cases (45.8%), the IAN was visible during the operation. Groove was present in 37.4% of cases. 26.5% of the cases showed lingual cortical thinning, while specious root conformation explained the formation of darkening on the radiographic images of an additional 9.6% of the cases. IAN exposure (Pthird molar roots is more often the result of fenestration of the inferior alveolar canal wall or groove formation of the root than lingual cortical thinning.

  1. Lingual split versus surgical bur technique in the extraction of impacted mandibular third molars: a systematic review.

    Science.gov (United States)

    Steel, Ben

    2012-09-01

    The relative merits of different surgical techniques to extract impacted mandibular third molars have been debated for many years. A simple classification is those using a bur and those using a chisel. This article seeks to identify any differences in postoperative outcomes between the surgical bur and lingual split techniques. Using inclusion criteria allowing randomized controlled trials only, 5 studies are identified of which 4 are used in the analysis. The following outcomes are investigated: pain, swelling, trismus, bleeding, delayed healing/infection, and disturbance to lingual and inferior alveolar nerve function. The limited analysis allowed by the number and size of the studies leads to tentative conclusions of no difference between postoperative pain and swelling, and some evidence of less trismus for the lingual split technique. There is some weak evidence of a similar incidence of neurological sequelae between the 2 techniques, but this is not a strong conclusion owing to the small size of the included studies. There are inadequate data regarding bleeding and delayed healing/infection for analysis. Copyright © 2012 Elsevier Inc. All rights reserved.

  2. Functional and comparative study of lingual papillae in four species of bear (Ursidae) by scanning electron microscopy.

    The eight current species of bear (Ursidae) are widely distributed throughout Europe, Asia, and America. They are mainly encountered in the northern hemisphere, except for the spectacled bear and the sun bear, which are also found in the south of the equator. Adaptations of the masticatory apparatus (teeth, tongue, and musculature) to diet are one of the factors that imply the greatest structural changes in the cranium. This diet may be carnivorous, herbivorous, melliferous, or insectivorous, with one type of food predominating according to the time of year. The way in which food is eaten determines the morphology of the lingual surface; generally speaking, all bears put their mouth to the food, which, initially, they lick or they let the food stick to their tongue, as occurs when insects are eaten. As in all mammals, a distinction can be made between mechanical and gustatory papillae and the development and distribution of which depend on the species and their eating habits. In this study of the complete tongues of four species of adult bears, we describe the morphology of the lingual surfaces, the different types of papillae, their characteristics, and topographic distribution. It was seen that there were five main types of lingual papillae: filiform, conical, fungiform, foliate, and vallate. Morphology of the microgrooves and pores was similar to that observed in other mammals. In general, there were no great differences among the four species of bears studied, perhaps due to the similarity in the kind of food they consume in captivity.

This paper describes the oral and dental findings in a family containing two affected brothers. The family pedigree is informative, as the mother has had children by three partners. The two affected individuals are full brothers. The first affected brother has delayed dental development, severe hypodontia and small tooth crown size. Mesio-distal and bucco-lingual dimensions were measured on the study models and compared with population data. The younger brother also has delayed dental development but only mild hypodontia. Their half sister has severe hypodontia but no signs of Carpenter Syndrome. This family study demonstrates two affected individuals with typical clinical features and a pedigree compatible with autosomal recessive inheritance. Small tooth crown size has been shown by standardized measurement and evidence advanced that hypodontia is not part of the syndrome but a coincidental finding which segregates independently. We have also shown that the marked delay in emergence of teeth is associated more with problems of tooth eruption, possibly related to the bony abnormalities, than to a generalized delay in dental development.

    Full Text Available We studied the arteries of the tongue of Sus scrofa doméstica (Linnaeus, 1 758 from 20 animals whose tongues were slaughtered while fresh and kept cooled (4ºC for transportation. The blood vessels of 1 5 animals were flowed with water (37ºC, injected with stainedlatex, fixated with phormaldeid and dissected with magnifying glass. We injected 5 tongues with air and acetone PA; later, we injected again with air and at last with vinyl stained acetate. The material was put in water for 24 h and, after this, submerged in sulfuric acid 30% for two weeks to reveal the arterial system mold. The arteries provided dorsal, ventral and collateral branches in the following way: dorsal branches at the tongue root - three branches (50%, four branches (46.6%, five branches (3.4%; arrangements of the following dorsal and ventral branches at the tongue body - one ventral and two dorsal (46.6%, one ventral and three dorsal (23.3%, one ventral and one dorsal (23.3%, one ventral and four dorsal (3.4% and one ventral branch (3.4%. At the lingual apex, the artery was parallel between antimers, made a medial curve, and reached the counter-lateral artery, establishing anastomoses by inosculation, forming arterial islands from which radial branches to the tip of the tongue were originated.

    Dark Skies, Bright Kids! (DSBK) is a dynamic education and public outreach organization at the University of Virginia, focused on enhancing elementary level science education in rural and underserved communities. DSBK thrives on the efforts of undergraduate, graduate and post-doctoral volunteers. Early in the program, our volunteers encountered difficulties connecting with “English as a second language” students. To meet that challenge, DSBK volunteers created art with short descriptions of astronomical objects in both Spanish and English to help communicate concepts across the language barrier. Building on this initial success, our simple art project has evolved into a full educational children’s book targeted at 2nd - 5th grade students. Though originally in Spanish and English, a partnership with the University of Alberta (Canada) has produced a French translation of the text, broadening the outreach potential of the book. Here we present our 'Snapshots of the Universe' for broad distribution to classrooms, school libraries and homes, with emphasis on those serving multi-lingual populations, as a unique tool for introducing astronomy concepts at the elementary school level.

    Full Text Available Bubalus bubalis (Ruminantia: Bovidae, Bovinae is an economically important animal of many Asian countries, making significant contribution to milk and meat production. Sub clinical infection of the reproductive tract is one of the important causes for reduced reproductive efficiency in dairy herd of buffaloes. Antimicrobial peptides are component of innate immune system which helps in augmenting the resistance to infection at epithelial surfaces e.g reproductive tract epithelium. In this study we have identified a ß-defensin called Lingual Antimicrobial Peptide (LAP in buffalo reproductive tract. Interestingly the gene was 100 % identical to the LAP isolated from the tongue epithelium of Bos taurus. The 195 bp cDNA of LAP codes for 64 amino acids and of which 50% are cationic amino acids. Phylogenetic studies indicate that LAP of reproductive epithelium of buffalo is different from other beta defensins isolated from the various tissues of same species, but all beta defensin were found to have the same progenitor gene. It is concluded that buffalo reproductive tract epithelium lining contains LAP. [Vet. World 2011; 4(3.000: 120-123

  7. Effects of Afferent Stimulation of the Lingual Nerve on Gastrointestinal Motility in the Rat

    1987-06-01

    Full Text Available Effects of afferent stimulation of the lingual nerve (LNAS on gastrointestinal motility and the reflex pathways which mediate the response to LNAS were investigated in rats. LNAS induced excitatory, inhibitory or biphasic responses in the stomach, duodenum and proximal colon. These responses continued after bilateral vagotomy, but were abolished after additional bilateral splanchnicotomy or transection of the spinal cord between Th4 and Th5. The inhibitory, excitatory and biphasic responses induced by LNAS were not affected by decerebration. Both after administration of atropine (0.2 mg/kg, i.v. and guanethidine (3-5 mg/kg, i.v., LNAS-induced excitatory and inhibitory responses were abolished in most cases, but the slight inhibitory response in the stomach and duodenum to LNAS remained in a few cases. These results suggest that the reflex centers which cause LNAS-induced excitatory and inhibitory responses are located in the dorsal nucleus of vagus and that the reflex pathways include the vagus and splanchnic nerves.

    The aim of this study was to elucidate the sublingual and intralingual courses of the lingual nerve (LN) in the ventral tongue region, providing a clinical guide for safe surgical procedures such as frenectomy. We evaluated 16 specimens (32 sides) by gross observation after detailed dissections, and a further 6 specimens were examined after Sihler staining. All specimens were harvested from embalmed Korean cadavers. We classified the innervation patterns of the LN into 5 types and confirmed the distribution of the LN in the tip of the tongue. The classification of the LN was made with reference to a line formed by the interlacing of the styloglossus and genioglossus muscles. Based on the course of LN and the presence of a tiny twig (twigs directly innervating the ventral mucosa of the tongue, TM) directly innervating the sublingual mucosa, the course of the LN was classified as being straight, curved, or vertical and with or without the TM. Straight, curved, and vertical courses without the TM were seen in 9.4%, 46.9%, and 18.8% of the cases, respectively. Straight and curved courses with the TM were observed in 6.3% and 18.8% of the cases, respectively. Sihler staining revealed that the tongue tip is innervated by the LN. These findings indicate that surgical manipulations at the ventral tongue region might damage the LN and result in numbness of the tongue tip, and provide a useful anatomic reference for various surgical procedures involving the ventral tongue region.

    This investigation examined primarily epidermal specializations of the adult horse tongue by light, scanning and transmission electron microscopy. Samples were collected from seven regions of the normal tongue of various breeds of horse. The filiform papillae, present on the dorsal and lateral aspects but not the ventral aspect of the tongue, were short, slender and finger-like structures with variable-shaped terminae. The epidermal thickness and height of dermal ridges were reduced on fungiform and vallate papillae, but tissue architecture and keratinocyte ultrastructure of most of the lingual epidermis corresponded to the common mammalian epidermal paradigm. One unique finding was the highly localized clustering of epidermal cells with exceptionally high content of PAS-negative trichohyalin cytoplasmic granules at a location atop the dermal ridges and beneath the base of filiform papillae. These granular cells were immediately subjacent to clusters of clear, non-granulated epidermal cells. It is believed that this integumentary specialization may enhance the structural strength at this localized site of the tissue architecture, in relationship to the mechanical papillae.

    The idea of identifying oral lesions with a precancerous nature, i.e. in the sense of pertaining to a pathologic process with an increased risk for future malignant development, of course is to prevent frank malignancy to occur in the affected area. The most common oral lesion with a precancerous...... nature is oral leukoplakia, and for decades it has been discussed how to treat these lesions. Various treatment modalities, such as systemic therapies and surgical removal, have been suggested. The systemic therapies tested so far include retinoids, extracts of green tea, inhibitors of cyclooxygenase-2...

    Full Text Available Background: Basaloid squamous cell carcinoma of oral mucosa is a rare and aggressive variant of squamous cell carcinoma. They can be differentiated from squamous cell carcinomas by their distinct clinical and histopathological features. Methods: 45 year old female patient presented with extra oral exophytic mass and intra-oral ulcerative lesion on right buccal mucosa and vestibule. The patient was referred for routine blood examination and radiography followed by incisional biopsy. The biopsy specimen was fixed, processed and stained with Hematoxylin and Eosin for further microscopic examination. Results: On microscopic examination basaloid cells were seen proliferating along with dysplastic squamous cells in the connective tissue stroma. Conclusion: Based on the histopathological findings a diagnosis of ′Basaloid squamous cell carcinoma′ was made. The patient was referred to department of Oral and Maxillofacial Surgery for excision of the lesion followed by radiotherapy.

    Full Text Available INTRODUCTION: Oral hygiene is an essential element of health education programs for schoolchildren. AIM: The study aims to assess the skills when conducting oral hygiene of a group of schoolchildren and to conduct training in its rules. MATERIAL AND METHODS: The study covers 30 children aged 6-12 years. The training was conducted by the methods of the visual pedagogy and implementation of the technique “Say, show, do”. The assessment of the oral-hygiene status was held by the simplified oral hygiene index-Greene & Vermillion. RESULTS AND CONCLUSION: The children do not have proper oral hygiene habits. The daily oral care is inadequate. The number of cleaned tooth surfaces during oral hygiene practice is small. Children have no developed proper oral hygiene skills, and brush only the vestibular surfaces of the teeth (80%, 13.3% the vestibular and the occlusal, and 6.7% only cover lingual surfaces too. The unsatisfactory oral hygiene status is also a result of using only one type of toothbrush movements. The improvement of children's health knowledge should play key role in correcting their oral hygiene technique.

  14. Oral pathology.

    2008-05-01

    Oral disease is exceedingly common in small animal patients. In addition, there is a very wide variety of pathologies that are encountered within the oral cavity. These conditions often cause significant pain and/or localized and systemic infection; however, the majority of these conditions have little to no obvious clinical signs. Therefore, diagnosis is not typically made until late in the disease course. Knowledge of these diseases will better equip the practitioner to effectively treat them. This article covers the more common forms of oral pathology in the dog and cat, excluding periodontal disease, which is covered in its own chapter. The various pathologies are presented in graphic form, and the etiology, clinical signs, recommended diagnostic tests, and treatment options are discussed. Pathologies that are covered include: persistent deciduous teeth, fractured teeth, intrinsically stained teeth, feline tooth resorption, caries, oral neoplasia, eosinophilic granuloma complex, lymphoplasmacytic gingivostomatitis, enamel hypoplasia, and "missing" teeth.

    2015-01-01

    Full Text Available Context: Tongue-tie (more formally known as ankyloglossia is a congenital anomaly characterized by an abnormally short lingual frenulum, which may restrict mobility of the tongue tip impairing its ability to fulfill its functions. The clinical significance of ankyloglossia is varied; rarely symptomatic to a host of problems including infant feeding difficulties, speech disorders, malocclusions, and others. Aims: The need of this study was to evaluate the occurrence and severity of tongue-tie and its association with the type of malocclusions in two populations and also to correlate the various malocclusion traits with the grades of tongue-tie. Subjects and Methods: A total of 700 school children in the age group of 9-17 years were examined for the presence of tongue-tie, 350 from regular schools and 350 from special schools. The presence was evaluated, measured, and graded into Grades I-V according to Kotlow′s method. The malocclusion was assessed according to Angle′s classification. Severity of crowding was assessed by Little′s irregularity index in each case. Various other malocclusion traits were visually assessed, in relation to the positions of the teeth. Statistical Analysis Used: Spearman′s rank correlation method was used to test the relationship between type of malocclusions, grades of tongue-tie and severity of crowding. Significance was considered at the (P < 0.05 level. Results: Statistically significant differences were seen between grades of tongue-tie and Angle′s types of malocclusion and Spearman′s correlation between them showed negative correlation. The Spearman′s correlation showed a negative correlation between tongue-tie grades and severity of crowding. Conclusions: As the grade of tongue-tie increased, its association with Classes I and II malocclusion decreased. The lower grades of tongue-tie are associated with increased lower incisor crowding. Shorter, tight frenulums are more associated with maxillary

    Full Text Available Renal cell carcinoma (RCC accounts for the 3% of all solid tumors. Despite continuous improvement in the therapy regimen, less has been achieved in terms of enabling an earlier diagnosis: the neoplasia usually reveals its presence at an advanced stage, obviously affecting prognosis. The most frequent sites of secondary disease are shown to be lungs (50-60%, bone (30-40%, liver (30-40% and brain (5%; while the head and neck district seems to account for less than 1% of patients with primary kidney lesion. We report here the case of a 70-year old man who presented with acute renal failure due to abdominal recurrence of RCC 18 years post nephrectomy. After a few months of follow up without any systemic therapy due to the renal impairment, the patient presented a vascularized tongue lesion that was demonstrated to be a secondary localization of the RCC. This lesion has, therefore, been treated with microsphere embolization to stop the frequent bleeding and to lessen the unbearable concomitant symptoms it caused, such as dysphagia and pain. A tongue lesion that appears in a RCC patient should always be considered suspect and a multidisciplinary study should be conducted both to assess whether it is a metastasis or a primary new lesion and to understand which method should be selected, if necessary, to treat it (surgery, radiation or embolization. Lingual metastasis should be examined accurately not only because they seem to implicate a poor prognosis, but also because they carry a burden of symptoms that not only threatens patients’ lives but also has a strong impact on their quality of life.

    The epithelium of mammalian tongue hosts most of the taste buds that transduce gustatory stimuli into neural signals. In the field of taste biology, taste bud cells have been described as arising from "local epithelium", in distinction from many other receptor organs that are derived from neurogenic ectoderm including neural crest (NC). In fact, contribution of NC to both epithelium and mesenchyme in the developing tongue is not fully understood. In the present study we used two independent, well-characterized mouse lines, Wnt1-Cre and P0-Cre that express Cre recombinase in a NC-specific manner, in combination with two Cre reporter mouse lines, R26R and ZEG, and demonstrate a contribution of NC-derived cells to both tongue mesenchyme and epithelium including taste papillae and taste buds. In tongue mesenchyme, distribution of NC-derived cells is in close association with taste papillae. In tongue epithelium, labeled cells are observed in an initial scattered distribution and progress to a clustered pattern between papillae, and within papillae and early taste buds. This provides evidence for a contribution of NC to lingual epithelium. Together with previous reports for the origin of taste bud cells from local epithelium in postnatal mouse, we propose that NC cells migrate into and reside in the epithelium of the tongue primordium at an early embryonic stage, acquire epithelial cell phenotypes, and undergo cell proliferation and differentiation that is involved in the development of taste papillae and taste buds. Our findings lead to a new concept about derivation of taste bud cells that include a NC origin.

    Full Text Available Context: It was suggested that the accessory neurovascular foramina of the mandible might be of significance in relation to the effectiveness of local anesthesia following the routine inferior alveolar nerve block. Aims: To investigate the incidence of neurovascular foramina over the lingual surface of the mandible in South Indian population. Settings and Design: The study was conducted at the department of anatomy. Materials and Methods: The study included 67 human adult dry mandibles, the exact ages and sexes of which were not known. The location and number of neurovascular foramina were topographically analyzed. Statistical Analysis Used: Descriptive statistics. Results: The foramina were observed in 64 mandibles (95.5% and were often multiple in most of the cases. They were located between the two medial incisors in 8 mandibles (1.9%, between the medial and lateral incisor in 34 mandibles (50.7%; 25-bilateral; 7-right; 2-left, between the lateral incisor and canine in 7 mandibles (10.4%; 2-bilateral; 3-right; 2-left, between the canine and first premolar in 6 cases (8.9%; 3 on each side. Foramina were also present around the genial tubercle in 56 mandibles (83.6%. Among them, 52 mandibles showed a single foramen just above the genial tubercle, 34 mandibles had foramina below the tubercles, 13 mandibles had foramina on the right side of genial tubercle and 17 were having on the left side. Conclusion: Since the anatomical details of these foramina are important to various fields of dentistry and oncology, the present investigation was undertaken. The clinical significance and implications are emphasized.

    The aims of this study were to evaluate the effectiveness of a lower lingual holding arch (LLHA) in maintaining arch length, and to compare the effectiveness of two LLHAs made of two different gauges (0.9 and 1.25 mm) of stainless steel (SS) wire. The sample comprised 44 subjects (24 males and 20 females) who for various reasons attended orthodontic clinics at Jordan University of Science and Technology Dental Teaching Center. The subjects were randomly divided into two treatment groups. The first group contained 20 subjects (12 males/8 females, average age 10.76 ± 0.75 years). The LLHA used in this group was made of 0.9 mm SS wire. The second group comprised 24 subjects (12 males/12 females, average age 10.57 ± 0.54 years). The LLHA used in this group was made of 1.25 mm SS wire. The third group consisted of 23 subjects (15 males/8 females, average age 10.63 ± 0.66 years) who served as the control. The records consisted of lateral cephalograms, dental pantomograms, and study casts. Paired t-test, analysis of variance, and chi-square tests were used to determine whether significant differences existed between the groups. In both treatment groups, the lower incisors proclined and moved forward, and space loss of the lower primary second molar occurred. The LLHA made of 0.9 mm SS was superior to that made of 1.25 mm SS in terms of arch length preservation.

    ABSTRACT Objective: To evaluate stainless steel archwire static friction in active and passive self-ligating lingual and conventional brackets with second-order angulations. Methods: Two conventional lingual brackets for canines (STb light/Ormco; PSWb/Tecnident), and two self-ligating brackets, one active (In-Ovation L/GAC) and the other passive (3D/ Forestadent), were evaluated. A stainless steel archwire was used at 0°, 3° and 5° angulations. Metal ligatures, conventional elastic ligatures, and low friction elastic ligatures were also tested. A universal testing machine applied friction between brackets and wires, simulating sliding mechanics, to produce 2-mm sliding at 3 mm/minute speed. Results: Two-way analysis of variance demonstrated a significant effect of the interaction between brackets and angulations (p < 0.001). Tukey test indicated that the highest frictional resistance values were observed at 5° angulation for In-Ovation L, PSWb bracket with non conventional ligature, and STb bracket with metal ligature. As for 3D, PSWb with conventional or metal ligatures, and STb brackets with non conventional ligature, showed significantly lower static frictional resistance with 0° angulation. At 0° angulation, STb brackets with metal ties, In-Ovation L brackets and 3D brackets had the lowest frictional resistance. Conclusions: As the angulation increased from 0° to 3°, static friction resistance increased. When angulation increased from 3° to 5°, static friction resistance increased or remained the same. Self-ligating 3D and In-Ovation L brackets, as well as conventional STb brackets, seem to be the best option when sliding mechanics is used to perform lingual orthodontic treatment. PMID:27653262

    The mucosal membrane of the oral cavity displays at times classical developmental lesions considered to be variations of normal structures rather than having disease characteristics. Of these lesions leukoedema, Fordyce granules, geographic-, fissured- and hairy tongue, median rhomboid glossitis and lingual varices were studied in 598 patients referred to the School of Dentistry, Tehran, Iran. The prevalence was studied in relation to age, gender, occupation, education, smoking habits, general health, addictions and or drug therapies. Oral developmental lesions were seen in 295 patients (49.3%). Only Fordyce granules (27,9%), fissured tongue (12,9%), leukoedema (12,5%) and hairy tongue (8,9%) had enough cases for statistical analysis. Three of these lesions increased with age but not fissured tongue. All were more common in men. After adjusting for age, the parameters education, occupation and complaints upon referral had little influence on the prevalence of the lesions. Fewer Fordyce granules were seen in oral mucosa of smoking men. Leukoedema and hairy tongue were significantly associated with smoking, leukoedema with diabetes mellitus. We conclude that there was a highly significant association between these oral lesions and age, gender and smoking. Few significant associations were found between oral lesions and general diseases.

    Oral candidiasis (OC) is a common fungal disease encountered in dermatology, most commonly caused by an overgrowth of Candida albicans in the mouth. Although thrush is a well-recognized presentation of OC, it behooves clinicians to be aware of the many other presentations of this disease and how to accurately diagnose and manage these cases. The clinical presentations of OC can be broadly classified as white or erythematous candidiasis, with various subtypes in each category. The treatments include appropriate oral hygiene, topical agents, and systemic medications. This review focuses on the various clinical presentations of OC and treatment options.

    Full Text Available Myiasis is a relatively rare condition arising from the invasion of body tissues or cavities of living animals or humans by maggots or larvae of certain species of flies. It is an uncommon clinical condition, being more frequent in underdeveloped countries and hot climate regions, and is associated with poor hygiene, suppurative oral lesions; alcoholism and senility. Its diagnosis is made basically by the presence of larvae. The present article reports a case of oral myiasis involving 20 larvae in a patient with neurological deficiency.

    Oral mucosa demonstrates regional variations that reflect contact with food during mastication. Though known qualitatively, our aim was to quantitatively assess regions to establish a measurable baseline from which one could compare in pathological and comparative studies, in which the abrasiveness of diets may differ. We assessed variations in the epithelial-connective tissue junction (rete ridges counts), collagen organization within the lamina propria, and elastin composition of the lamina propria of 15 regions of the labial (buccal) gingiva, lingual gingiva, vestibule, and palate. All characteristics varied more between regions within the same individual than between individuals. Lingual gingiva had high rete ridges counts, high level of collagen organization, and moderate elastin composition compared to other regions. The labial gingiva had few rete ridges, high collagen organization, and low elastin. The vestibule had the fewest average of rete ridges, least organized collagen, and high elastin. The hard palate had the highest average of rete ridges, high collagen organization, and the lowest elastin content. The soft palate conversely had the smallest average of rete ridges, moderate collagen organization, and the highest elastin composition. Our results indicate that comparison of these quantitative histological differences is warranted only for collagen organization and elastin composition. Differences in rete ridges counts were not statistically significant. Most histological characteristics observed were not significantly different between dentulous and edentulous cadavers, and the group containing all individuals. An exception was the level of collagen fiber organization within the lamina propria, which was higher in most regions when teeth were present.

    Retroglossal obstruction is one of the etiologies causing obstructive sleep apnea (OSA) and can be addressed by removing some tissues of the tongue base. However, because of its deep-seated location, its surgical removal is still challenging. Although coblation technique has been introduced, its efficacy and morbidity need further evaluation, particularly in Asians. This study aimed to assess its safety and effectiveness and to identify outcome prognosticators. Forty-seven OSA patients who underwent coblation lingual tonsil removal were included. Retroglossal obstruction was confirmed by drug-induced sleep videofluoroscopy. Attended full-night polysomnography was performed twice; before and 6 months after surgery in 27 patients. The tongue base was fully exposed with three deep-seated traction sutures, visualized with a 30° or 70° endoscope, and ablated using a coblator. Surgical success was defined with postoperative apnea hypopnea index (AHI) 50 %. Postoperative morbidities were evaluated. Demographic and polysomnographic parameters between success and failure groups were compared. None of the patients had immediate postoperative hemorrhage. Postoperatively, one patient had delayed hemorrhage and one patient severe respiratory difficulty. Taste loss, tongue dysmotility, dental injury or severe oropharyngeal stricture were absent. A mean AHI decreased from 37.7 ± 18.6 to 18.7 ± 14.8/h (P Coblation lingual tonsil removal technique showed minimal morbidity and favorable outcome in Koreans. The surgical outcome might be associated with the severity of single respiratory events.

    We observed the external surface and connective tissue cores (CTCs) of the lingual papillae (filiform, fungiform and vallate papillae) of adult Spotted seals (Phoca largha) using SEM and light microscopy. The tongue was V-shaped and its apex was rather rounded. On the dorsal surface from apex to the one-third posterior of the tongue, the lingual mucosa was densely covered by filiform papillae, with a scatted distribution of dome-like fungiform papillae, which have orthokeratinized epithelium. At the posterior part of the tongue, filiform papillae were totally diminished and their epithelium was parakeratinized. Approximately 6-7 vallate papillae were arranged in a V-shape on the posterior of the tongue. After removal of the epithelium, the CTCs of the filiform papillae that were distributed at apex consisted of a primary core and approximately 5-6 rod-shaped small accessory cores. The CTCs of filiform papillae that were distributed at anterior part of the tongue lacked primary protrusions and possessed approximately 10-15 rod shaped small accessory cores that were arranged in a horseshoe manner. The CTCs offungiform papillae had cylindrical primary cores and were fringed with accessory protrusion. In the Vallate papillae, taste buds were only seen at the dorsal epithelium.

    We recently reported that the polycomb complex protein Bmi1 is a marker for lingual epithelial stem cells (LESCs), which are involved in the long-term maintenance of lingual epithelial tissue in the physiological state. However, the precise role of LESCs in generating tongue tumors and Bmi1-positive cell lineage dynamics in tongue cancers are unclear. Here, using a mouse model of chemically (4-nitroquinoline-1-oxide: 4-NQO) induced tongue cancer and the multicolor lineage tracing method, we found that each unit of the tumor was generated by a single cell and that the assembly of such cells formed a polyclonal tumor. Although many Bmi1-positive cells within the tongue cancer specimens failed to proliferate, some proliferated continuously and supplied tumor cells to the surrounding area. This process eventually led to the formation of areas derived from single cells after 1-3 months, as determined using the multicolor lineage tracing method, indicating that such cells could serve as cancer stem cells. These results indicate that LESCs could serve as the origin for tongue cancer and that cancer stem cells are present in tongue tumors.

    Sensorimotor impairment of the tongue has the potential to affect speech and swallowing. The purpose of this study was to critically examine the effects of nerve preservation and reinnervation after reconstruction of the base of tongue on patient-perceived outcomes of quality of life (QoL) related to speech and swallowing through completion of the EORTC QLQ-H&N35 standardised questionnaire. Thirty participants with a diagnosis of base of tongue cancer underwent primary resection and reconstruction with a radial forearm free flap, which may or may not have included nerve repair to the lingual nerve, hypoglossal nerve or both. Eight QoL domains sensitive to changes in motor and sensory nerve function were included in the analysis. Transected lingual and hypoglossal nerves were associated with difficulty in swallowing, social eating, dry mouth and social contact. There were fewer problems reported when these nerves were either repaired or left intact. There were no significant differences between patient nerve status and QoL outcomes for speech, sticky saliva and use of feeding tubes. This study was the first to examine the impact of sensory or motor nerve transection and reconstruction on health-related QoL outcomes. © 2013 John Wiley & Sons Ltd.

    The cancer which appears in the mobile portion of the tongue is the most common neoplasm of the oral cavity. The objective of this study was to analyse oral tongue cancer epidemiology in a population of 610 patients diagnosed between 1990 and 2008 and detailed in the Tumour Registry of the Madrid region. A retrospective analysis based on the following variables provided in the Tumour Registry was achieved: age, gender, histology, stage, location, treatment. Descriptive and analytic statistics with these variables, using Pearson's Chi-square test to study the relationship between the qualitative variables. Patients' mean age was 61.53±13.95 years, with a gender ratio of 2.09:1 (413 males vs 197 females). The lesion was mainly localized in the lateral border of tongue, with other sites (dorsal face, ventral face, lingual tonsil, contiguous sites, tongue NOS) represented at lower rates. Squamous cell carcinomas (94.9%) far outweighted other histologies (salivary gland tumours, soft tissue tumours, haematolymphoid tumours). 59% of the cases appeared in localized stages, versus 35.2% in regional and 4.8% in distant stages. Surgery was the most frequently used treatment, followed by surgery in combination with radiotherapy. Oral tongue cancer is a disease of the elderly, with a male predominance. It mainly appears in its lateral border, localized squamous cell carcinomas representing the great majority of lingual neoplasms.

  15. Oral calcitonin

    Full Text Available Ronald C Hamdy,1,2 Dane N Daley11Osteoporosis Center, College of Medicine, East Tennessee State University, 2Veterans Affairs Medical Center, Johnson City, TN, USAAbstract: Calcitonin is a hormone secreted by the C-cells of the thyroid gland in response to elevations of the plasma calcium level. It reduces bone resorption by inhibiting mature active osteoclasts and increases renal calcium excretion. It is used in the management of postmenopausal osteoporosis, Paget's disease of bone, and malignancy-associated hypercalcemia. Synthetic and recombinant calcitonin preparations are available; both have similar pharmacokinetic and pharmacodynamic profiles. As calcitonin is a peptide, the traditional method of administration has been parenteral or intranasal. This hinders its clinical use: adherence with therapy is notoriously low, and withdrawal from clinical trials has been problematic. An oral formulation would be more attractive, practical, and convenient to patients. In addition to its effect on active osteoclasts and renal tubules, calcitonin has an analgesic action, possibly mediated through β-endorphins and the central modulation of pain perception. It also exerts a protective action on cartilage and may be useful in the management of osteoarthritis and possibly rheumatoid arthritis. Oral formulations of calcitonin have been developed using different techniques. The most studied involves drug-delivery carriers such as Eligen® 8-(N-2hydroxy-5-chloro-benzoyl-amino-caprylic acid (5-CNAC (Emisphere Technologies, Cedar Knolls, NJ. Several factors affect the bioavailability and efficacy of orally administered calcitonin, including amount of water used to take the tablet, time of day the tablet is taken, and proximity to intake of a meal. Preliminary results looked promising. Unfortunately, in two Phase III studies, oral calcitonin (0.8 mg with 200 mg 5-CNAC, once a day for postmenopausal osteoporosis and twice a day for osteoarthritis failed to

    We report a rare case of a patient who was referred to the Department of Oral medicine in Zagreb, Croatia. The patient was 20 years old, otherwise healthy and not taking any medication. She presented with irregular erosions partially covered with pseudomembranes that involved both lips and retrocomissural mucosa. Discrete erosion was also noticed on her lower lingual gingiva in the area 42. She reported a propolis solution self-medication for treatment of recurrent aphthous ulcers. After ten days of propolis application, lip and oral lesions developed. Patch test to propolis was proven. We highlight the fact that some folk medicine medications, such as propolis, although being known for many decades to be helpful in various conditions, in some individuals might lead to unwanted side-effects due to its antigenic potential. Additionally, every colleague, during the differential diagnosis of the oral lesions must bear in mind unwanted reactions to folk medicine products.

    Oral leiomyomas are considered to be rare neoplasms, but they may be encountered more frequently than generally believed. Three types of leiomyomas are commonly described: solid leiomyomas, angiomyomas, and epithelioid leiomyomas. Three cases of solid leiomyoma are presented, all of which occurred in the anterior mandibular mucobuccal fold. Leiomyomas can be easily confused with other spindle-cell tumors. The necessity of using special stains, especially Mallory's phosphotungstic acid hematoxylin, is discussed.

    1. The aim of the study was to examine the morphology of the tongue and the histochemical features of the lingual salivary glands in this species. 2. The tongue was elongated, terminating in a rather sharp, dagger-like apex. On the surface of the tongue and situated between the body and root of the tongue, two rows of conical papillae, the sharp apices of which pointed towards the posterior part of the tongue, were observed. The keratinised epithelium lining the dorsal surface lacked typical gustatory papillae. However, it was observed that taste buds were present in the epithelium of the lingual body and root. The tongue was supported by a structure composed of hyaline cartilage, the paraglossum, which extended from the lingual root to the apex. Simple branched tubular glands, which were encapsulated by connective tissue, were embedded within the submucosa in the body (anterior salivary glands) and root (posterior salivary glands) of the tongue. It was observed that the secretion of the lingual glands contained neutral mucins, proteoglycans containing carboxylic acid, weak and strong sulphated groups, N-acetylated sialomucins, but lacked glycogen. 3. It was demonstrated that, the general morphological features, papillary distribution of the tongue and the histological structure of the mucosa epithelium and the supportive elements displayed similarity to those of other domestic avian species. It was also determined that, in view of the particular feeding types, in the partridge, the presence of the papillary crest was not correlated with diet.

    We observed the external surface and connective tissue cores (CTCs), after exfoliation of the epithelium of the lingual papillae (filiform, fungiform, foliate and vallate papillae) of the common raccoon (Procyon lotor) using scanning electron microscopy and light microscopy. The tongue was elongated and their two-third width was almost fixed. Numerous filiform papillae were distributed along the anterior two-thirds of the tongue and fungiform papillae were distributed between the filiform papillae. Eight vallate papillae that had a weak circumferential ridge were distributed in a V-shape in the posterior part of the tongue and numerous taste buds were observable in the circumferential furrows of vallate papillae. Weak fold-like foliate papillae were observable at the lateral edge in the posterior part of the tongue and a few salivary duct orifices were observable beneath the foliate papillae. An islet-like structure with numerous taste buds, was observable on the deep part of the salivary duct of foliate papillae. Large conical papillae were distributed at the posterior part and root of the tongue. After removal of epithelium, filiform papillae of CTCs were appeared to be a thumb or cone-like main core and associating several finger-like short accessory cores. These cores were surrounded an oval concavity. The main core was situated behind the concavity and associated with accessory cores. CTCs of fungiform papillae were cylinder-like with numerous vertically running ridges and with a few concavities seen at the top of the cores. CTCs of vallate papillae and their surrounded circumferential ridge were covered with numerous pimple-like protrusions. The lingual papillae of Common raccoon's tongue had morphological feature of carnivore species.

    Objectives (1) Describe trends in the diagnosis of ankyloglossia and the use of lingual frenotomy and (2) analyze patient- and hospital-level factors as compared with the total pediatric discharge population. Study Design National database analysis. Methods We reviewed available data from 1997 to 2012 using the Kids' Inpatient Database, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality. All weighted pediatric discharges with ankyloglossia, newborn feeding difficulty, or lingual frenotomy were analyzed for variables of sex, payer, zip code median income, hospital ownership, location/teaching status, bed size, region, and children's hospital status. Chi-square analysis with 95% CIs and odds ratio were used to identify differences between the study group and the total database discharge population. Results Diagnosis of ankyloglossia increased each year of publication (every third year)-with 3934, 5430, 7785, 11,397, 19,459, and 32,837 children, respectively, from 1997 to 2012-with the largest increase in the last 6 years. Similarly, frenotomy increased with 1279, 1633, 2538, 3988, 6900, and 12,406 procedures. Compared with the total discharge population, children with ankyloglossia or frenotomy were more often male (63.6% ankyloglossia, 65.3% frenotomy vs 51.2%), privately insured (60.1%, 62.1% vs 43.6%), from a higher median-income zip code (78.1%, 78.2% vs 68.6%), and in Midwest region (29.3%, 32.3% vs 21.7%). Conclusion These pilot data show increases in diagnoses of ankyloglossia and use of frenotomy. There is a preponderance of children who are male, privately insured, or Midwest residents being diagnosed and treated for ankyloglossia. This broad variation may reflect local practice patterns or imply cultural and socioeconomic bias.

    Over 60 million women use highly efficient and safe modern combined oral contraceptives (OCs) every day. A women who takes the oral contraceptive for 5 years before the age of 30 will actually live 12 days longer, although a woman taking the pill for the 1st time for 5 years after the age of 30 will have her life span reduced on the average by 80 days. OC related morbidity and mortality mostly occur in women over 35 who smoke. Combined low dose OCs are safe for women who do not smoke, at least to 45 years of age and probably to the menopause. The prescription of OCs is also safe to the young adolescent. The pill does not interfere with maturation of the hypothalamic-pituitary ovarian axis and does not increase the incidence of amenorrhoea, oligomenorrhoea or infertility in later life. Patients with contraindications to estrogen therapy are excluded from OC use (history of thromboembolism, major heart disease, liver disease, breast cancer). Low-dose (30-35 mcg estrogen-containing monophasic or triphasic) pills are recommended. Combined oral contraceptives contain either ethinyl estradiol (1.7 to 2 times more potent) or mestranol. After absorption the progestagens, norethisterone acetate, ethynodiol diacetate and lynoestrenol are all metabolized to norethisterone. The progestagen-only pill has about a 2% failure rate and poorer cycle control than the combined pill, but it lacks estrogenic, progestagenic and androgenic side effects. This pill is suitable for the lactating mother, for smokers over 35, for hypertensive patients, and for those with a history of thrombosis. The efficacy of the progestagen-only pill is restored in 3 days of pill taking. Postcoital contraception is an alternative: treatment can be given for at least 72 hours after intercourse. The Yuzpe method calls for the patient to take 2 combined oral contraceptive tablets containing levonorgestrel and ethinyl estradiol (Eugynon or Ovral) followed by a further 2 tablets 12 hours later.

    Experiments were undertaken to determine if nitric oxide (NO) plays a role in regulation of basal blood flow in the oral cavity of pentobarbital anesthetized cats and, if so, to quantify this effect using dose-response relationships. Blood flow was continuously measured from the surface of the tongue and mandibular gingiva (laser-Doppler flowmetry) and from the lingual artery (ultrasonic flowmetry). Cardiovascular parameters also were recorded. Administration of the nonselective inhibitor of nitric oxide synthase (NOS), L-NAME (0.08-20 mg/kg i.v.), produced a dose-related increase of blood pressure associated with decreases of blood flow at all three measurement sites. Maximal blood flow depression of 50-60% was seen 30-60 min after administration of 1.25 mg/kg of L-NAME. D-NAME (1.25 mg/kg i.v.) was inactive at all sites. Subsequent administration of L-arginine partially reversed effects of L-NAME in the lingual artery and tongue, but not in the gingival circulation. The neuronally selective NOS inhibitor, 7-nitroindazole (7-NI, 30 mg/kg i.p.), was devoid of effect on any of the measured parameters. These results suggest that endothelial (but not neuronally derived) NO plays an important role in control of basal blood flow in oral tissues of the cat.

    We studied the effect of grape seed extract Burgund Mare (BM) on oral carcinogenesis and compared it with that of curcumin (CU). Wistar rats were divided into six groups (n = 10): 4-nitro-quinoline-1-oxide (4NQO) oral carcinogenesis was induced to groups 1 - 5; groups 2 and 3 received BM and CU respectively during initiation and groups 4 and 5 BM and CU during post-initiation of carcinogenesis; group 6 represented the negative control group. Total malondialdehyde (MDA) and reduced glutathione (GSH) were assayed fluorometrically in oral tissue (gingival, jugal, palatal, lingual mucosa) and serum. Histopathological exam was performed and a dysplasia score given to each oral mucosal lesion. Ki67, cyclin D1, p63, Bcl2 and p53 were immunohistochemically evaluated. BM and CU reduced tissue MDA values elevated by 4NQO (P = 0.000). The difference between CU and BM effect was significant in the initiation (P = 0.02) but not in the post-initiation phase of carcinogenesis (P = 0.58). Tissue GSH levels decreased by 4NQO (P < 0.001) were not significantly modified by BM or CU. Serum MDA levels increased by 4NQO (P = 0.000) were significantly lowered by CU (P = 0.04) and BM (P = 0.04) during initiation and by CU during post-initiation of carcinogenesis (P = 0.01). CU was more potent than BM during post-initiation of carcinogenesis (P = 0.01). Serum GSH lowered by 4NQO (P = 0.55) was significantly decreased by BM and CU (P < 0.012), with no significant difference between groups receiving BM or CU. Moderate dysplasia was the most advanced dysplasia induced and gingival localization the most frequent. Both BM and CU lowered dysplasia scores, with BM being the most efficient during post-initiation of carcinogenesis (P = 0.001). Ki67, cyclin D1, p63, Bcl2 and p53 expression increased with dysplasia scores. BM showed chemopreventive properties during initiation and post-initiation of oral carcinogenesis, reducing local and general oxidative stress and the intensity of dysplasia

    Summary Background: Using lingual enamel surfaces for bracket placement not only has esthetic advantages, but may also be suitable in terms of reducing frequencies of enamel decalcifications. Objective: To test the null-hypothesis that there is no significant difference in enamel decalcification or cavitation incidence adjacent to and beneath bracket bases between two lingual multi-bracket (MB) appliances that are different in terms of design, material composition, and manufacturing technology (group A: WIN, DW-LingualSystems; group B: Incognito, 3M-Unitek), taking into account patient- and treatment-related variables on white spot lesion (WSL) formation. Methods: Standardized, digital, top-view photographs of 630 consecutive subjects (16214 teeth; n Incognito = 237/6076 teeth; n WIN = 393/10138 teeth; mean age: 17.47±7.8; m/f 43.2/56.8%) with completed lingual MB treatment of the upper and lower permanent teeth 1–7 were screened for decalcification or cavitation adjacent to and beneath the bracket bases before and after treatment, scored from 0 to 7. Non-parametric ANOVA was used for main effects ‘appliance type’, ‘gender’, ‘treatment complexity’, ‘grouped age’ (≤16/>16 years), and ‘treatment duration’ as covariable, at an α-level of 5%. Results: About 2.57% [5.94%] of all teeth in group A [B] developed decalcifications. Subject-related incidence was 9.59% [16.17%] for upper incisors in group A [B], and 12.98% [25.74%] for all teeth 16–46. There were significant effects by gender, age, and treatment duration. Conclusion: The null-hypothesis was rejected: sub-bracket lesions were significantly less frequent in group A, while frequencies of WSL adjacent to brackets were not significantly affected by appliance type. In view of the overall low incidences of lingual post-orthodontic white-spot lesions, the use of lingual appliances is advocated as a valid strategy for a reduction of enamel decalcifications during orthodontic treatment.

    Full Text Available Filariasis affecting animals can rarely cause infections in human beings through the accidental bite of potential vectors. The resulting infection in man, known as zoonotic filariasis occur worldwide. Human dirofilariasis, the most common zoonotic filariasis, is caused by the filarial worm belonging to the genus Dirofilaria. Dirofilarial worms, which are recognized as pathogenic in man can cause nodular lesions in the lung, subcutaneous tissue, peritoneal cavity or eyes. Oral dirofilariasis is extremely rare and only a few cases have been documented. We report an interesting case of dirofilariasis due to Dirofilaria repens involving buccal mucosa in a patient who presented with a facial swelling. The clinical features, diagnostic issues and treatment aspects are discussed. This paper stresses the importance of considering dirofilariasis as differential diagnosis for subcutaneous swelling of the face, especially in areas where it is endemic.

    Full Text Available Oral sex is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents. The various type of oral sex practices are fellatio, cunnilingus and analingus. Oral sex is infrequently examined in research on adolescents; oral sex can transmit oral, respiratory, and genital pathogens. Oral health has a direct impact on the transmission of infection; a cut in your mouth, bleeding gums, lip sores or broken skin increases chances of infection. Although oral sex is considered a low risk activity, it is important to use protection and safer sex precautions. There are various methods of preventing infection during oral sex such as physical barriers, health and medical issues, ethical issues and oral hygiene and dental issues. The lesions or unhealthy periodontal status of oral cavity accelerates the phenomenon of transmission of infections into the circulation. Thus consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

    Kawasaki disease (KD) was first described in 1967 by Kawasaki, who defined it as "mucocutaneous lymph node syndrome". KD is an acute systemic vasculitis, which mainly involves medium calibre arteries; its origin is unknown, and it is observed in children under the age of 5, especially in their third year. The principal presentations of KD include fever, bilateral nonexudative conjunctivitis, erythema of the lips and oral mucosa, changes in the extremities, rash, and cervical lymphadenopathy. Within KD, oral mucositis - represented by diffuse mucous membrane erythema, lip and tongue reddening and lingual papillae hypertrophy with subsequent development of strawberry tongue - can occur both in the acute stage of the disease (0-9 days), and in the convalescence stage (>25 days) as a consequence of the pharmacological treatment. KD vascular lesions are defined as systemic vasculitis instead of systemic arteritis. This study analyzed the anatomical-pathological substrata of oral mucositis in a baby affected by Kawasaki disease and suddenly deceased for cardiac tamponade caused by coronary aneurysm rupture (sudden cardiac death of a mechanical type).

    Full Text Available A amiloidose é uma doença complexa rara de difícil diagnóstico que ocorre devido à deposição de substância amilóide no meio extracelular. Ao ser diagnosticado na cavidade bucal, deve-se monitorar o paciente a fim de avaliar possíveis complicações sistêmicas da doença. Diante disso, o objetivo do presente estudo é relatar um caso de amiloidose oral em uma paciente do gênero feminino de 72 anos de idade. Baseado nos sinais clínicos observados, a hipótese diagnóstica foi de fibroma traumático. Após realização de biópsia e exame histopatológico, o diagnóstico foi de amiloidose oral, o que foi confirmado com a coloração do espécime com o reagente vermelho congo. Depósitos de amilóide foram encontrados no tecido conjuntivo, na avaliação através da luz polarizada, que apresentou birrefringência. Tal achado foi preocupante, já que a amiloidose geralmente acomete diversos tecidos levando a comprometimentos sistêmicos. Por essa razão a paciente foi encaminhada a procurar atendimento médico. No entanto, houve abandono do tratamento e a mesma veio a óbito 6 meses após o diagnóstico da doença. Lesões orais aparentemente simples podem revelar doenças raras e de difícil tratamento. O diagnóstico preciso e acompanhamentos médicos são fundamentais na sobrevida do paciente.

    Full Text Available Diabetes Mellitus (DM is a syndrome in metabolism of carbohydrates which indicated by the increased level of blood glucose and also may increase salivary glucose levels. Oral ulcer has been frequently recognized in diabetic patients, which can be due to increased glucose in oral fluids and immune dysfunction. This study aimed to determine the correlation of blood glucose levels and salivary glucose levels with oral ulcer in diabetic patients. Analytic observational study was carried out through the determination of blood glucose levels just by way of strip using a glucometer and salivary glucose levels with the method "GOD-PAP test enzymatic colorimetric". Oral ulcer was determined in presenting ulcer on 30 patients with DM. The results showed r = 0.228, which is higher salivary glucose levels followed by high levels of blood glucose, and intraoral examination of oral ulcer found in the whole sample and the most location commonly found in buccal mucosa and lingual. It was concluded that there is a correlation between blood glucose levels and salivary glucose levels, and glucose levels affect the occurrence of oral ulcer in patients with DM

    Full Text Available Statement of Problem: Labial access cavity preparation is a conventional method in endodontic treatment of the anterior teeth, but in some conditions labial cavity preparation is recommended.Purpose: The aim of this study was to compare labial and lingual access cavity preparation in the permanent anterior teeth with labial caries in terms of the remaining tooth structure and fracture resistance. Materials and Method: In this experimental study, 150 intact permanent human anterior teeth were selected in 5 groups each with 30 teeth including the maxillary central, maxillary lateral, maxillary canine, mandibular incisors and mandibular canine. A class V cavity with similar ratios to dimensions of each tooth was prepared on the labial surface of all specimens. The volumes of each of these teeth were measured by Penta Pycnometer before and after class V cavity preparation (V1, V2. Each group was randomly divided into 2 equal subgroups (n=15. Access cavities were prepared labially in subgroup A and lingually in subgroup B; then, the remained volume of each tooth was measured again (V3. The mean proportional volume loss of each tooth was calculated through access preparation (V2-V3/V1. Then, the specimens were embedded in acrylic resin blocks and subjected to load with a universal testing machine.Results: The differences of mean of theremained volume and fracture resistance of the two subgroups were statistically significant in all groups ( p <0.05 and those teeth with labial access showed more remained volume and fracture resistance than lingual access. Conclusion: Labial access cavity preparation can enhance the remained volume and fracture resistance as compared to lingual access in endodontic treatment of the anterior teeth with labial caries especially in mandibular incisors.

    2016-06-01

    Full Text Available The need for integrating geospatial information (GI data from various heterogeneous sources has seen increased importance for geographic information system (GIS interoperability. Using domain ontologies to clarify and integrate the semantics of data is considered as a crucial step for successful semantic integration in the GI domain. Nevertheless, mechanisms are still needed to facilitate semantic mapping between GI ontologies described in different natural languages. This research establishes a formal ontology model for cross-lingual geospatial information ontology mapping. By first extracting semantic primitives from a free-text definition of categories in two GI classification standards with different natural languages, an ontology-driven approach is used, and a formal ontology model is established to formally represent these semantic primitives into semantic statements, in which the spatial-related properties and relations are considered as crucial statements for the representation and identification of the semantics of the GI categories. Then, an algorithm is proposed to compare these semantic statements in a cross-lingual environment. We further design a similarity calculation algorithm based on the proposed formal ontology model to distance the semantic similarities and identify the mapping relationships between categories. In particular, we work with two GI classification standards for Chinese and American topographic maps. The experimental results demonstrate the feasibility and reliability of the proposed model for cross-lingual geospatial information ontology mapping.

    Objectives To investigate the clinical value of combined dye-isotope technique in detecting sentinel lymph node (SLN) and to examine whether the characteristics of SLN accurately predict cervical lymph node metastasis in lingual carcinoma. Methods Thirty patients with lingual carcinoma without lymph metastasis were injected with a dose of about 18.5 MBq of 99mTc-SC (sulfur colloid), around the tumor tissues before surgery, and lymphoscintigraphy was performed 5, 10, 30, 60 minutes, and 6 hours after injection. In the following day, all patients were injected with isosulfan blue dye around the primary tumor during surgery to trace SLN and underwent standard cervical lymph node dissection after SLN dissection. The pathological results of SLN were compared with standard lymph node dissection for their ability to accurately predict the final pathological status of the cervical lymph nodes.Results SLN was successfully identified in 100% of the patients. Both positive and negative predictive values of SLN were 100%. The accuracy rate was 100%, and there were no false negatives. Conclusions The detection of SLN using combined dye-isotope technique could accurately predict cervical lymph node metastasis in lingual carcinoma.

    Despite the increasing and successful use of laser in Medicine and Odontology, the possible iatrogenic and otherwise deleterious side effects of this radiation remain mostly unknown. In previous studies, it was shown that both the embryonic and the post-hatched chicken constitute reliable experimental models for this type of studies. Hence, the purpose of the present work was to analyze the structural and cytochemical alterations of the lingual glands of the newborn chicken irradiated with low energy He-Ne laser. This laser produced regressive structural changes of the glands towards the embryonic stage as well as hyperplasia of the reserve glandular basal cells. Furthermore, a decrease in the glycoprotein content and a rise in the sulphated glycosaminoglycans were also found. These results corroborate the pathogenic effects of the He-Ne- laser on the experimental model employed and, at the same time, emphasize the importance of considering, regarding clinical applications, possible previous neoplastic alterations as well as adverse reactions which might appear once laser therapy has been installed.

    Conclusions The assessment of postural responses (PR) based in a feedback control system model shows selective gains in different bands of frequencies adaptable with child development. Objective PR characterization of pre-lingual cochlear implant users (CIU) in different sensory conditions. Methods Total energy consumption of the body's center of pressure signal (ECCOP) and its distribution in three bands of frequencies: band 1 (0-0.1 Hz), band 2 (0.1-0.7 Hz), and band 3 (0.7-20 Hz) was measured in a sample of 18 CIU (8-16 years old) and in a control group (CG) (8-15 years old). They were assessed in a standing position on a force platform in two sensory conditions: 1 = Eyes open. 2 = Eyes closed and standing on foam. Results In condition 1, total ECCOP of PR and its proportion of energy consumption in the three bands of frequencies were similar between CIU and CG (p > 0.05). In condition 2, CIU have significantly higher ECCOP, mainly in high frequencies (bands 2 and 3) (p < 0.05). ECCOP values decreased with age also, mainly in bands 2 and 3. This behavior is interpreted in the control system model proposed as an adaptation process related with child development.

    To assess the association between the prevalence of tongue cyst-positive and antigen-positive pigs across different settings in Africa, to evaluate whether examining pigs for cysts could be used as a rapid surveillance tool for identifying geographical areas with a higher probability of high transmission of cysticercosis. Published data were collated from 26 study sites across Africa that reported the prevalence of porcine cysticercosis by both lingual and serological examinations. The study sites were located in 10 countries across Africa. Seroprevalence rates ranged from 4% to 41%. Despite the varied study sites, the relationship between the two variables was highly consistent and suggests identification of tongue cysts may be useful for cysticercosis surveillance. We found that all areas with more than 10% of pigs having cysts in their tongues had at least 30% seroprevalence (PPV of 100%), although this cut-off is less reliable at predicting that an area is of low transmission (NPV of 84%). Assessing the prevalence of tongue cyst-positive pigs is a potential rapid epidemiological tool for identifying areas at high risk of cysticercosis, although further refinement and validation is required using standardised data sets. © 2016 The Authors.

    The present study was undertaken to examine whether potential levels of innate immune factors (lingual antimicrobial peptide (LAP), lactoferrin (LF) and lactoperoxidase (LPO)) in colostrum are associated with subsequent milk somatic cell count (SCC) in dairy cows. Quarter milk samples were collected daily for 1 week postpartum to measure LAP and LF concentrations and LPO activity. SCC in milk was determined weekly for 2 months postpartum and its correlations to concentrations of LAP and LF and LPO activity were examined. Only small variations of all immune factors were found among four udders in each individual cow, whereas there were great differences in these factors among cows. Negative correlation was detected only between LPO activity and mean and maximum SCC, whereas its relationship was not significant. LAP and LF concentrations were significantly correlated positively to mean, maximum and minimum SCC. These results suggest that the great difference in innate immune factors among animals and high LAP and LF concentrations in colostrum may be associated with subsequent high incidence of SCC increase.

    The aim of the present study was to examine changes in innate immune factors in the milk of mastitic dairy cows treated with antibiotics. Cows in the antibiotics group (n = 13) were infused into the mammary gland with cefazolin on the sixth day after mastitis was diagnosed (the day of the mastitis diagnosis = day -6). The control group (n = 12) was not treated. Milk samples were collected once every 2 days from days -6 to 12 and somatic cell count (SCC), lingual antimicrobial peptide (LAP), and lactoferrin (LF) concentrations and lactoperoxidase (LPO) activity were measured. SCC and LF concentrations in the antibiotics group markedly decreased after the antibiotic treatment. When cows in the antibiotics group were divided according to SCC on day 0, LAP concentrations and LPO activity in cows with a lower SCC on day 0 (<5 × 10(6) cell/mL) were significantly higher and lower than those in cows with a higher SCC, respectively. These results suggest that LF concentration decreased with decrease in SCC after treatment and that LAP concentration and LPO activity differed depending on the severity of mastitis. This is the first report to reveal the dynamics of innate immune factor in milk of cows treated for clinical mastitis.

    Most organisms feed on a variety of prey that may differ dramatically in their physical and behavioural characteristics (e.g. mobility, mass, texture, etc.). Thus the ability to modulate prey capture behaviour in accordance with the characteristics of the food appears crucial. In animals that use rapid tongue movements to capture prey (frogs and chameleons), the coordination of jaws and tongue is based on visual cues gathered prior to the prey capture event. However, most iguanian lizards have much slower tongue-based prey capture systems suggesting that sensory feedback from the tongue may play an important role in coordinating jaw and tongue movements. We investigated the modulation of prey capture kinematics in the agamid lizard Pogona vitticeps when feeding on a range of food items differing in their physical characteristics. As the lizard is a dietary generalist, we expected it to be able to modulate its prey capture kinematics as a function of the (mechanical) demands imposed by the prey. Additionally, we investigated the role of lingual sensory feedback by transecting the trigeminal sensory afferents. Our findings demonstrated that P. vitticeps modulates its prey capture kinematics according to specific prey properties (e.g. size). In addition, transection of the trigeminal sensory nerves had a strong effect on prey capture kinematics. However, significant prey type effects and prey type by transection effects suggest that other sources of sensory information are also used to modulate the prey capture kinematics in P. vitticeps.

    Full Text Available Aims: This study aims to analyze the effects of intrusive force, retraction force, and torque control on the maxillary central incisors with varying degrees of collum angle in labial and lingual orthodontic treatment procedures using finite element analysis. Subjects and Methods: Four pairs of three-dimensional finite element models (FEMs representative of maxillary central incisor with periodontal ligament (PDL and alveolar bone were constructed using ANSYS software (version 5.4, ANSYS Inc., Canonsburg, PA, USA. The models with 0°, 5°, 10°, and 15° were created based on crown root angulation. Four models for labial and four models for lingual orthodontic procedure were constructed. Each model was subjected to three forces, i.e., retraction force of 1 N, lingual root torque of −5 × 10−3 N and intrusive force of 0.64 N on crown with labially and lingually positioned brackets. Principal stress and strain, center of rotation and root apex displacement were monitored. Statistical Analysis Used: Not required (FEM study. Results: With the increase in collum angle, the stress-strain distribution in PDL was increased in both labial orthodontics (LaO and lingual orthodontics (LiO. Stress-strain distribution in the PDL with LiO was more in all the models as compared to LaO. There was more of tipping movement as collum angle increased from 0° to 15° in both LaO and LiO. The amount of intrusion reduced as the collum angle increased in both the systems. However, more of intrusion was seen in LaO. With increase in collum angle, the center of rotation moved cervically in both the systems. Conclusions: From the present study, we conclude that as the collum angle increased, the stress-strain distribution increased in LaO and LiO. The center of rotation shifted cervically, and the intrusion decreased when collum angle increased. The values were more marked in LiO.

    The lack of information on oral health in Laos makes it difficult to estimate the need and methods for preventing oral disease. This study identified problems concerning the oral health of Lao children. The study subjects were 59 school children who lived in Pakkading District. Dental caries, gingivitis malocclusions, temporomandibular joint (TMJ) disorders, dental plaque, and calculus were examined. We observed an average of 1.6 decayed, missing, and filled teeth (DMFT) and 4.1 decayed and filled deciduous teeth (dft) per child. 25.4% had gingivitis scores from 16 to 20 on the papillary, marginal, and attached (PMA) index; 29.6% had one or more occlusal abnormality; and 0% had signs of TMJ disorders. 93.5% of the children had at least one buccal or lingual tooth surface with plaque covering more than two thirds of the surface; 32.6% had dental calculus. Oral health promotion programs for children should prioritise prevention and treatment of caries. It is likely that the high rate of gingivitis in Lao children is due mainly to unsuccessful plaque control in daily life. In addition to descriptive epidemiological studies of dental diseases in other areas, the influence of sociological and behavioural factors on oral health should be analyzed epidemiologically to promote child health.

    This article is the first known case report of Fraser syndrome in the dental literature. Its purpose was to present the clinical manifestations, oral findings, and dental treatment of a 14-year, 10-month-old female patient. Fraser syndrome is a rare recessive autosomal genetic disorder characterized by multisystemic malformation, usually comprising cryptophthalmos, syndactyly, and renal defects. The child presented with: (1) hydrocephaly; (2) face asymmetry; (3) low-inserted ears; (4) flat nose bridge; (5) cryptophthalmos; (6) bilateral absence of eyeballs; (7) hypertelorism; (8) syndactyly on the left fingers and toes; (9) skeletal defects; and (10) lower limb asymmetry. The intraoral examination revealed: (1) complete primary denture; (2) malocclusion; (3) tooth crowding; (4) ogival palate; (5) normal labial frena; (6) absence of lingual frenum (not compromising the tongue movements); (7) parched lips; (8) supragingival calculus adhered to all tooth surfaces; and (9) moderate gingivitis. The dental treatment consisted of periodic monitoring of the patient's oral health status and supragingival scaling associated with topical applications of 0.12% chlorhexidine digluconate gel at 2-week intervals to reduce gingivitis.

    This presentation will demonstrate and discuss any surgical applications of the Argon dental laser. This presentation will also increase the awareness and basic understanding of the physical principals of the Argon laser. The wavelength of the Argon laser is specifically absorbed by red pigments such a hemoglobin which is abundant in oral soft tissue. The result is a sharp clean incision with minimal thermal damage to adjacent healthy tissue. Preprosthetic procedures such as full arch vestibuloplasty, labial and lingual frenectomy, and epulis fissuratum removal will be demonstrated. Other soft tissue management procedures such as minor periodontal pocket elimination surgery (gingivectomy), removal of hyperplastic granulation tissue from around poorly maintained implants, and the removal of granulation and/or cystic tissue from the apex of teeth undergoing endodontic (apicoec-tomy) surgery will also be demonstrated and discussed. Provided basic oral surgery protocol is followed, surgical procedures utilizing the Argon laser can be accomplished with minimal bleeding, minimal trauma and with minimal post-operative discomfort.

    Full Text Available Twenty two tongues of buffalo collected from the slaughter house of Mousl city (11 tongues for adult animals 3-4 years and11tongues for small ages 1 weake-2 monthes. Two groups were used in this study, twelve samples for anatomical study and ten samples for histological study, in each group of this study, the tongues were divided into four regions from apex to the end of the root. The tongue is a muscular organ which consists of dorsal and ventral surfaces, it is formed from three parts (apex, body and root. The lingual fossa and torus linguae both appear on the dorsal surface. The total average of the tongue length in adult animals (36.00±0.97 cm while the highest average of the length, width and thickness found in the third region. The total length in small ages was (16.92±0.98 cm and the highest average of length and thickness again it happens in third region and the highest width in this age group found in the second region. The investigation of the normal anatomical structures of the tongue distinguished four lingual papillae (filiform, fungiform, conical and circumvalate while the lenticuler papillae absent in both age groups. The filiform and fungiform papillae spread over the dorsal surface and ventro-lateral surface terminat abruptly at the ventro-lateral border forming a distinct straight line from apex to the torus linguae in both ages. The present work reveals that the highest average of filiform papillae in both surface (dorsal and ventro-lateral surface founds in second region in adult group, while in small group founds in first region. The highest average of fungiform papillae in both surface of both age groups are in the apex of tongue. The highest average of conical and circumvalate papillae in both age group (adult and young were on torus linguae. The histological study has been used the shape, diameter and the type of epithelium which covered the papillae in both groups. The filiform papillae are long fine projection beading

    Growing number of evidences have suggested that oral fat sensing, mediated by a glycoprotein CD36 (cluster of differentiation 36), plays a significant role in the development of obesity. Indeed, a decreased expression of CD36 in some obese subjects is associated with high dietary fat intake. In the present study, we examined whether an increase in body mass index (BMI) is associated with altered oleic acid lingual detection thresholds and blood lipid profile in young Algerian teenagers (n = 165). The obese teenagers (n = 83; 14.01 ± 0.19 years; BMI z-score 2.67 ± 0.29) exhibited higher lingual detection threshold for oleic acid than lean participants (n = 82, 13.92 ± 0.23 years; BMI z-score 0.03 ± 0.0001). We also studied the association between rs1761667 polymorphism of CD36 gene and obesity. The AA and AG genotypes were more frequent in obese teenagers, whereas GG genotype was more common in lean participants. The A-allele frequency was higher in obese teenagers than that in lean children. We report that rs1761667 polymorphism of CD36 gene and oro-gustatory thresholds for fat might play a significant role in the development of obesity in young teenagers.

The results demonstrate a prominent role for Shh in fungiform papilla induction and patterning and indicate differences in morphogenetic control of fungiform and circumvallate papilla development and numbers. Furthermore, a previously unknown, broad competence of dorsal lingual epithelium to form fungiform papillae on both anterior and posterior oral tongue is revealed.

    We do not know the natural history of dysphagia in classical Rett syndrome (RTT) by stage or age. This study investigated swallowing physiology in 23 females ages 1:7 to 5:8 (years, months) with classical Rett syndrome to determine common and distinguishing features of dysphagia in post-regression early Pseudostationary Stage III. In-depth analysis of videofluoroscopic swallowing studies (VFSS) found dysmotility of oral stage events across subjects implicating oral apraxia. Impaired motility was further compromised by recurrent dystonic and dyskinetic movements that co-occurred with oral apraxia during oral ingestion in 78 % (n = 18) of the subjects with RTT. Of this group, 44 % displayed rocking and/or rolling lingual pattern, 56 % had recurrent oral tongue retroflexions, and/or elevated posturing of the tongue tip, and, 72 % displayed multi-wave oropharyngeal transfer pattern. The proportion of subjects whose swallowing motility was disrupted by aberrant involuntary tongue movements did not differ significantly between bolus types (liquid, puree, and solid) trialed. Liquid ingestion was significantly more efficient in subjects using bottles with nipples than their counterparts who used spouted or straw cups. Dystonic and dyskinetic tongue movements disrupted liquid ingestion in subjects using cups with spouts or straws significantly more than those using bottles. Analysis of food ingestion revealed that significantly more subjects were able to orally form, transport, and transfer a puree bolus into the pharynx than they were a solid bolus. A significantly larger number of subjects aspirated and penetrated liquid than they did puree or solid. No significant relationship was found between subjects with airway contamination and those with dystonic and dyskinetic tongue movements. Subjects' rocking and rolling lingual patterns were consistent with those evidenced in adults with Parkinson's disease. Subjects' tongue retroflexions were classified as provisionally

    Many oral diseases and conditions, including dental caries (cavities) and malocclusions, have their origins early in life. Prudent anticipatory guidance by the medical and dental professions can help prevent many of the more common oral health problems. This article provides information on the rationale for early dental examination and instructions for pediatric and family practitioners in scheduling and conducting an early oral intervention appointment. In addition, feeding practices, non-nutritive sucking, mouth breathing, and bruxing are discussed, including their effects on orofacial growth and development.

    Oral steroid contraception is a popular method of family planning worldwide. Over the past several decades, this method of contraception has changed significantly by decreasing the estrogen dose, changing the progestin component, and reducing the hormone free interval. Despite the popularity of oral steroid contraception, there has been much criticism regarding the associated risks of venous thromboembolism and stroke. Despite these established, yet uncommon risks, oral steroid contraception has many important health benefits. This review highlights the available formulations of oral contraceptives along with their evidence-based associated risks and benefits. Highlights regarding future directions for development of novel oral contraceptives are also addressed.

    Full Text Available Many oral lesions may need to be diagnosed by removing a sample of tissue from the oral cavity. Biopsy is widely used in the medical field, but the practice is not quite widespread in dental practice. As oral pathologists, we have found many artifacts in the tissue specimen because of poor biopsy technique or handling, which has led to diagnostic pitfalls and misery to both the patient and the clinician. This article aims at alerting the clinicians about the clinical faults arising preoperatively, intraoperatively and postoperatively while dealing with oral biopsy that may affect the histological assessment of the tissue and, therefore, the diagnosis. It also reviews the different techniques, precautions and special considerations necessary for specific lesions.

    A 58-year-old man named J.S. was diagnosed with non-Hodgkin lymphoma and underwent treatment with standard rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy. He presented to his local outpatient clinic for evaluation and laboratory tests on day 10 after cycle 3. During this visit, J.S. reported great difficulty opening his mouth with significant gingival and lingual pain when eating and drinking in spite of prophylactic oral care. Laboratory test results revealed a white blood cell count of 0.9 k/ul, hemoglobin level of 8.9 g/dl, platelets of 100 k/ul, serum creatinine level of 1 mg/dl, and blood urea nitrogen level of 29 mg/dl.

    2009-01-01

    Full Text Available Traumatic neuromas are characterized by the presence of pain, burning, or paresthesia, associated with a history of trauma, normally surgery, in the same site. In the oral cavity, the most commonly affected sites are the lip, tongue, and mental nerve area. Pressure on the suspected area usually provokes pain. They microscopically consist of a proliferation of nerve fascicles embedded in a background of collagen. We present a case of a 42-year-old Latin American female patient complaining of a painful solitary nodule erupting on the lingual surface of the mandibular body. Histopathological analysis showed a traumatic neuroma associated with mature ganglion cells, which is an extremely unusual finding. After complete removal of the lesion the symptoms disappeared. To the best of our knowledge, this is the first case of a unique lesion with unusual clinical and histopathological features reported in the English language literature.

    The aim of the present study was to describe the tridimensional morphological characteristics of the lingual papillae and their connective tissue cores (CTCs) in Sprague Dawley rats. Four types of papillae were reported on the dorsal surface. Filiform papillae were distributed on the tongue surface and after epithelial maceration a conic and multifilamentary shape of the CTCs was revealed. Fungiform papillae were reported on the rostral and middle regions covered by a squamous epithelium. After the removal of the epithelium, the shape of a volcano with the taste orifice at its top was noted. Foliate papillae were composed of five pairs of epithelial folds situated on the lateral-caudal margin of the tongue. After the removal of the epithelium, they were shown to be limited by thin laminar projections. The vallate papilla with an oval shape was present in the caudal region and delimited by an incomplete groove. The morphological characteristics of the lingual papillae of Sprague Dowley rats, three-dimensional SEM images, and the types of papillae on the dorsal surface were similar to those reported previously in other rodent mammals. The maceration technique revealed the details of extracellular matrix with varied shapes form of connective tissue cores. PMID:25436229

    The aim of the study was to analyze morphological changes of the epithelial surface and underlying connective tissue cores (CTCs) of the lingual mucosa in the rat using a DMBA induced pre-cancerous experimental model. Lightmicroscopically, initially DMBA treated sections exhibited infiltration of chronic inflammatory cells. At 16 weeks, aldehyde-fuchsin (AF) positive elastic fibers decreased and were scanty in the juxtaepithelium. On the other hand, rather densely packed thick bundles of AF positive fibers were observable in the deep layers of lamina propria. Carcinomas were not found at any stage, however, epithelial dysplasia was observed at 24 weeks post-treatment with DMBA. Scanning electron microscopy revealed an irregular arrangement of filiform papillae 4-12 weeks following DMBA stimulation. Patchy degenerated areas were observed especially at 16-24 weeks post-treatment and filiform papillae were totally attenuated on the central part of the degenerated areas. After removal of the epithelium, attenuated CTCs were observed from 4-8 weeks. Morphology of CTCs seemed to be gradually remodeled and severely altered in the later stage. The CTCs were however attenuated and exhibited a patchy distribution. The animal experimental model in this study revealed degenerative morphological changes of CTCs of the lingual papillae in the precancerous stage induced by DMBA.

    Full Text Available Patients receiving radiotherapy or chemotherapy will receive some degree of oral mucositis The incidence of oral mucositis was especially high in patients: (i With primary tumors in the oral cavity, oropharynx, or nasopharynx; (ii who also received concomitant chemotherapy; (iii who received a total dose over 5,000 cGy; and (iv who were treated with altered fractionation radiation schedules. Radiation-induced oral mucositis affects the quality of life of the patients and the family concerned. The present day management of oral mucositis is mostly palliative and or supportive care. The newer guidelines are suggesting Palifermin, which is the first active mucositis drug as well as Amifostine, for radiation protection and cryotherapy. The current management should focus more on palliative measures, such as pain management, nutritional support, and maintenance, of good oral hygiene

    Oral focal mucinosis is considered as oral counterpart of cutaneous focal mucinosis. The preoperative diagnosis of mucinosis is almost impossible because of its rarity and clinical similarity to other lesions of various etiologies. The histological diagnosis of oral mucinosis is important to better understand the etiopathogenesis, treatment modalities, and any recurrence of the lesion besides differentiating from the other soft tissue lesions.The purpose of this paper is to report the first case of bimaxillary involvement with dome-shaped elevated, rounded, asymptomatic, normally colored swelling in left posterior palatal mucosa and left mandibular posterior region in a 25-year old woman who was diagnosed as oral focal mucinosis histopathologically.

  7. Oral microbiota and cancer

    Directory of Open Access Journals (Sweden)

    Jukka H. Meurman

    2010-08-01

    Full Text Available Inflammation caused by infections may be the most important preventable cause of cancer in general. However, in the oral cavity the role of microbiota in carcinogenesis is not known. Microbial populations on mouth mucosa differ between healthy and malignant sites and certain oral bacterial species have been linked with malignancies but the evidence is still weak in this respect. Nevertheless, oral microorganisms inevitably up-regulate cytokines and other inflammatory mediators that affect the complex metabolic pathways and may thus be involved in carcinogenesis. Poor oral health associates statistically with prevalence of many types of cancer, such as pancreatic and gastrointestinal cancer. Furthermore, several oral micro-organisms are capable of converting alcohol to carcinogenic acetaldehyde which also may partly explain the known association between heavy drinking, smoking, poor oral health and the prevalence of oral and upper gastrointestinal cancer. A different problem is the cancer treatment-caused alterations in oral microbiota which may lead to the emergence of potential pathogens and subsequent other systemic health problems to the patients. Hence clinical guidelines and recommendations have been presented to control oral microbiota in patients with malignant disease, but also in this area the scientific evidence is weak. More controlled studies are needed for further conclusion.

  10. Towards understanding oral health.

    Zaura, Egija; ten Cate, Jacob M

    2015-01-01

    During the last century, dental research has focused on unraveling the mechanisms behind various oral pathologies, while oral health was typically described as the mere absence of oral diseases. The term 'oral microbial homeostasis' is used to describe the capacity of the oral ecosystem to maintain microbial community stability in health. However, the oral ecosystem itself is not stable: throughout life an individual undergoes multiple physiological changes while progressing through infancy, childhood, adolescence, adulthood and old age. Recent discussions on the definition of general health have led to the proposal that health is the ability of the individual to adapt to physiological changes, a condition known as allostasis. In this paper the allostasis principle is applied to the oral ecosystem. The multidimensionality of the host factors contributing to allostasis in the oral cavity is illustrated with an example on changes occurring in puberty. The complex phenomenon of oral health and the processes that prevent the ecosystem from collapsing during allostatic changes in the entire body are far from being understood. As yet individual components (e.g. hard tissues, microbiome, saliva, host response) have been investigated, while only by consolidating these and assessing their multidimensional interactions should we be able to obtain a comprehensive understanding of the ecosystem, which in turn could serve to develop rational schemes to maintain health. Adapting such a 'system approach' comes with major practical challenges for the entire research field and will require vast resources and large-scale multidisciplinary collaborations.

    This investigation assessed awareness of the oral cavity of nonnative speakers acquiring English. University students (60 men, 60 women) were placed into three equal-size groups. The Less Experienced group lived in the USA less than 6 mo. (M = 3.3 mo., SD = 2.4). The More Experienced group lived in the United States 3 or more years (M = 5.0 yr., SD = 1.9). Native English speakers were the control group. Participants were recruited from undergraduate general education classes and passed a speech screening in English including accurate production of the seven English syllables tested, namely, suh, luh, tuh, kuh, ruh, shuh, and thuh. Participants answered four multiple-choice questions about lingual contact for each of the syllables imitated. Total test mean scores were significantly higher for the More Experienced group. Native speakers performed the task best. Findings support the effects of amount of time speaking the language. Training methods employed to teach English and slight dialectal variations may account for the significant differences seen in the two groups of nonnative speakers. Further study is warranted.

    Cancer is now the leading cause of death in Japan. A rapid increase in cancer mortality is expected as Japan is facing a super-aged society. Many causes of cancer are known to be closely linked to life style factors, such as smoking, drinking, and diet. The oral environment is known to be involved in the pathogenesis and development of various diseases such as bronchitis, pneumonia, diabetes, heart disease, and dementia. Because the oral cavity acts as the bodily entrance for air and food, it is constantly exposed to foreign substances, including bacteria and viruses. A large number of bacteria are endemic to the oral cavity, and indigenous oral flora act to prevent the settlement of foreign bacteria. The oral environment is influenced by local factors, including dental plaque, tartar, teeth alignment, occlusion, an incompatible prosthesis, and bad lifestyle habits, and systemic factors, including smoking, consumption of alcohol, irregular lifestyle and eating habits, obesity, stress, hormones, and heredity. It has recently been revealed that the oral environment is associated with cancer. In particular, commensal bacteria in the oral cavity are involved in the development of cancer. Moreover, Candida, human papilloma virus and Epstein-Barr virus as well as commensal bacteria have been reported to be associated with the pathogenesis of cancer. In this review, we introduce recent findings of the correlation between the oral environment and cancer.

    Herbal medication in the United States is a popular form of therapy. This paper provides an overview of the utilization of herbal supplements with particular emphasis on possible interactions with oral health drugs and oral manifestations. Herbal supplements are regulated by the Dietary Supplement Health and Education Act (DSHEA), which limits their regulation by the U.S Food and Drug Administration (FDA). A number of studies indicate that there is a progressive increase in the utilization of herbal supplements. The majority of consumers of these products are white, middle-aged women who have some college education. Many of the consumers use pharmaceutical drugs concurrently, but most do not inform their health-care providers about their use of herbal supplements. Various herbal supplements have been reported or are suspected to interact with certain oral health drugs, the most important one being 1) bromelain, cayenne, chamomile, feverfew, dong quai, eleuthro/Seberian ginseng, garlic, ginkgo, ginger, ginseng and licorice interacting with aspirin; 2) aloe latex, ephedra, ginseng, rhubarb, cascara sagrada, licorice, and senna interacting with corticosteriods; 3) kava, St. John's wort, chamomile, and valerian interacting with central nervous system (CNS) depressant drugs; and 4) herbs acting on the gastrointestinal system, altering the absorption of several orally administered drugs. Further, the use of some herbal supplements has been reported to be associated with oral manifestations, including aphthous ulcers, lip and tongue irritation, and swelling with feverfew; gingival bleeding with feverfew and ginkgo; tongue numbness with echinacea; xerostomia with St. John's wort; oral and lingual dyskinesia with kava; and salivation with yohimbe. These potential effects of herbal supplements in conjunction with factors related to regulation restrictions suggest that the use of these products may be associated with various adverse reactions that can affect oral health and

    Full Text Available Context: White lesions in the oral cavity may be benign, pre-malignant or malignant. There are no signs and symptoms which can reliably predict whether a leukoplakia will undergo malignant change or not. Many systemic conditions appear initially in the oral cavity and prompt diagnosis and management can help in minimizing disease progression and organ destruction. Aim : The aim of the paper was to study the clinical and histopathological patterns of white lesions in the oral cavity presented at the study setting and to study the factors associated with the histopathological patterns of the lesions. Settings and Design: A hospital based cross-sectional study of patients with white lesions in the oral cavity attending the Department of Dermatology and Venereology, Medical College, Thiruvananthapuram was done. Materials and Methods: After taking a detailed history, microscopic examination of Potassium hydroxide smear and an oral biopsy with histopathologial examination was done. Results : Out of the 50 patients in the study, clinically the diagnoses made were Lichen planus (32 patients; 64%, Frictional Keratosis (4;8%, Dysplasia (2;4%, Oral Hairy Leukoplakia (1;2%, Pemphigus Vulgaris (2;4%, Cutaneous Lupus Erythematosus (1;2%, Oral Submucous fibrosis (3;6% and Oral Candidiasis alone (5;10%. Out of the 45 patients who had undergone biopsy, 25 (55.6% had Lichen planus, 9 (20% had Frictional Keratosis and mild Dysplasia was found in 4 (8.9% patients. Conclusion : The measure of agreement between the clinical and pathological diagnosis was only 32%. Older age, difficulty in opening the mouth, consumption of non-smoked tobacco, site of the lesion (gingival, floor of mouth or lingual vestibule and presence of tenderness on the lesion were significantly associated with Dysplasia.

  5. Oral Floor and Gingival Metastasis of Cholangiocarcinoma: A Case Report and Review of the Literature

    2014-01-01

    Full Text Available The oral cavity is very unusual site of metastases even though wide spread metastatic disease may be present. The most common primary sites that metastasize to the oral cavity are lung, kidney, breast, and hepatocellular carcinoma. We present a rare case of a 77-year-old Caucasian female with metastasis from a cholangiocarcinoma to the oral floor contiguous with lingual gingival mucosa. The patient presented with left sided rib pain. A CT scan of the chest, abdomen, and pelvis showed multiple pulmonary nodules and a single dominant mass in the right lobe of the liver. This tumor was 6.5 cm with multiple satellite lesions surrounding it. The liver biopsy was diagnostic of a moderately to poorly differentiated adenocarcinoma, consistent with a primary cholangiocarcinoma. After undergoing one cycle of gemcitabine chemotherapy, the patient noticed an extremely rapidly growing mass involving her right lower gingiva and the entire right floor of her mouth. The biopsy of that mass also showed a moderately to poorly differentiated adenocarcinoma. The gingival tumor had a similar cytomorphology and immunophenotype as her cholangiocarcinoma. Therefore, an unusual site for metastatic cholangiocarcinoma was confirmed.

    Advances in bacterial genetics came with the discovery of the genetic code, followed by the development of recombinant DNA technologies. Now the field is undergoing a new revolution because of investigators' ability to sequence and assemble complete bacterial genomes. Over 200 genome projects have been completed or are in progress, and the oral microbiology research community has benefited through projects for oral bacteria and their non-oral-pathogen relatives. This review describes features of several oral bacterial genomes, and emphasizes the themes of species relationships, comparative genomics, and lateral gene transfer. Genomics is having a broad impact on basic research in microbial pathogenesis, and will lead to new approaches in clinical research and therapeutics. The oral microbiota is a unique community especially suited for new challenges to sequence the metagenomes of microbial consortia, and the genomes of uncultivable bacteria.

    1980-09-01

    Use of oral syringes at children's and ASHP-accredited residency hospitals in the United States was surveyed. Questionnaires were mailed to 131 hospitals; 117 (89.3%) were returned. Of the responding hospitals, 54.5% of children's hospitals and 67.1% of residency hospitals used oral syringes. There was no definite preference for a particular brand or type (glass vs. plastic) of syringe. Patients who often required liquid dosage forms, including pediatric and geriatric patients and patients with nasogastric tubes, were most frequently included in oral syringe distribution systems. Twenty-six of the 73 hospitals utilizing oral syringes used them for most unit dose liquids in all drug distribution systems. The remainder reported use for specific medications or circumstances. Expiration dating policies varied from 24 hours to one year to the manufacturer's expiration dating. The survey indicates widespread use of oral syringes and identifies a need for evaluation of medication stability in these devices.

    The possibility of examination of oral fluid bacteriocidal activity in complex diagnostics of oral mucosa disbiosis was evaluated. Thirty-seven patients were included in complex clinical and laboratory studies. The patients were divided in two groups: main group (30 patients exhibiting various grades of oral mucosa disbiosis) and control group (7 patients with no signs of oral disbiosis). The oral fluid bacteriocidal activity was examined by means of laser flow cytometry. Study results proved oral fluid bacteriocidal activity increase to correlate with the grade of oral mucosa disbiosis thus confirming the usefulness of the method in complex diagnostics of oral disbiosis.

    Full Text Available OBJETIVO: verificar quais características do frênulo da língua influenciam nas funções de sucção e deglutição em bebês nascidos a termo, com a finalidade de propor adequações no protocolo proposto por Martinelli et al (2012. MÉTODO: foi aplicado o protocolo de avaliação do frênulo da língua em 100 bebês saudáveis nascidos a termo. Os filmes obtidos na avaliação foram analisados por duas fonoaudiólogas especialistas em MO, com experiência em avaliação de frênulo lingual. Foram aplicados os testes Qui-quadrado seguido do teste exato de Fisher, além da análise de variância, considerando os dados qualitativos e quantitativos, respectivamente. RESULTADOS: nos 16 bebês que apresentaram alteração do frênulo lingual, verificou-se a relação entre: a tendência do posicionamento da língua durante o choro e o tempo entre as mamadas; a forma da língua quando elevada e o cansaço para mamar; bem como a fixação do frênulo na língua e o movimento da língua na sucção não nutritiva. Pela análise dos dados dos bebês com alteração de frênulo lingual, foi possível definir as características indicativas de alteração, que possibilitaram a adequação do protocolo inicial, e a atribuição de escores. CONCLUSÃO: a forma da língua, quando elevada durante o choro, influencia o movimento da língua durante a sucção não nutritiva, e o ponto de fixação do frênulo na língua influencia o ritmo da sucção durante a amamentação. O novo protocolo com escores é uma ferramenta efetiva para avaliar e diagnosticar alterações anatômicas do frênulo da língua e suas possíveis interferências na amamentação.PURPOSE: to observe the lingual frenulum characteristics that may interfere with the functions of suction and deglutition in full-term infants in order to have a final version of the protocol designed by Martinelli et al (2012.

    In this article, we report the successful use of miniscrews in a patient with an Angle Class III malocclusion, lateral open bite, midline deviation, and severe crowding. Simultaneously resolving such problems with conventional Class III treatment is difficult. In this case, the treatment procedure was even more challenging because the patient preferred to have lingual brackets on the maxillary teeth. As a result, miniscrews were used to facilitate significant asymmetric tooth movement in the posterior and downward directions; this contributed to the camouflage of the skeletal mandibular protrusion together with complete resolution of the severe crowding and lateral open bite. Analysis of the jaw motion showed that irregularities in chewing movement were also resolved, and a stable occlusion was achieved. Improvements in the facial profile and dental arches remained stable at the 18-month follow-up.

    Oral human papillomavirus (HPV) infection is the cause of 40% to 80% of oropharyngeal cancers; yet, no published study has examined the role of oral health in oral HPV infection, either independently or in conjunction with other risk factors. This study examined the relation between oral health and oral HPV infection and the interactive effects of oral health, smoking, and oral sex on oral HPV infection. Our analyses comprised 3,439 participants ages 30 to 69 years for whom data on oral HPV and oral health were available from the nationally representative 2009-2010 National Health and Nutrition Examination Survey. Results showed that higher unadjusted prevalence of oral HPV infection was associated with four measures of oral health, including self-rated oral health as poor-to-fair [prevalence ratio (PR) = 1.56; 95% confidence interval (CI), 1.25-1.95], indicated the possibility of gum disease (PR = 1.51; 95% CI, 1.13-2.01), reported use of mouthwash to treat dental problems in the past week (PR = 1.28; 95% CI, 1.07-1.52), and higher number of teeth lost (Ptrend = 0.035). In multivariable logistic regression models, oral HPV infection had a statistically significant association with self-rated overall oral health (OR = 1.55; 95% CI, 1.15-2.09), independent of smoking and oral sex. In conclusion, poor oral health was an independent risk factor of oral HPV infection, irrespective of smoking and oral sex practices. Public health interventions may aim to promote oral hygiene and oral health as an additional measure to prevent HPV-related oral cancers.

    A relationship between orosensory detection of dietary lipids, regulation of fat intake, and body mass index was recently suggested. However, involved mechanisms are poorly understood. Moreover, whether obesity can directly modulate preference for fatty foods remains unknown. To address this question, exploration of the oral lipid sensing system was undertaken in diet-induced obese (DIO) mice. By using a combination of biochemical, physiological, and behavioral approaches, we found that i) the attraction for lipids is decreased in obese mice, ii) this behavioral change has an orosensory origin, iii) it is reversed in calorie-restricted DIO mice, revealing an inverse correlation between fat preference and adipose tissue size, iv) obesity suppresses the lipid-mediated downregulation of the lipid-sensor CD36 in circumvallate papillae, usually found during the refeeding of lean mice, and v) the CD36-dependent signaling cascade controlling the intracellular calcium levels ([Ca2+]i) in taste bud cells is decreased in obese mice. Therefore, obesity alters the lipid-sensing system responsible for the oral perception of dietary lipids. This phenomenon seems to take place through a CD36-mediated mechanism, leading to changes in eating behavior. PMID:23840049

    The relationships between oral health conditions, dietary practices and nutritional status, and general health status in the older American are complex, with many interrelating factors. Just as inadequate nutrition can affect oral health, poor oral health status affects food choices and, thus, nutritional status. It is clearly essential that the primary care practitioner and/or screening health professionals always include an evaluation of oral status in assessment of an elderly person. Effective care for the elderly dental patient requires knowledge about the disease of aging and the impact of those diseases on oral health and nutrition, pharmacology and drug interactions and their impact on oral health status, the biology of aging including sensory changes, the relationship of general medicine and systemic diseases, and psychology and sociology. The attitudes of empathy and understanding, caring and compassion, respect and a positive attitude toward the older patient, and flexibility in treatment planning are also critical elements. The interdisciplinary team of physicians, nurses, nutrition professionals, dentists, and social service professionals must all work together to ensure that good oral health status and adequate nutrition are maintained in older Americans. Recognizing and treating oral health and nutrition problems are important in improving the health and quality of life for the elderly population. Research that can provide more answers to health care problems in this growing group; educating professionals with respect to the relationships between oral health and nutrition; and public policy changes with regard to provision and funding of nutrition services, especially when provided by registered and/or licensed nutrition professionals, contribute to improving the health and quality of life for elders.

    The pedodontic admission histories of 1600 Mexican children were analyzed, to determine general epidemiologic factors or oral habits, as well as their relationship with identifiable biopsychosociologic factors. Fifty-six percent of the children gave evidence of an oral habit, with significant predisposition among female patients, single children, subjects in poor physical health (particularly from allergies), as well as children with histories of chronic health problems. Oral habits should be considered a major health hazard because of their high incidence. Successful treatment requires a multidisciplinary approach to the basic cause of the problem.

  6. Oral sex and oral health: An enigma in itself

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Oral sex is commonly practiced by sexually active couples of various age groups, including male-female and same-gender adolescents. The various type of oral sex practices are fellatio, cunnilingus, and analingus. Oral sex can transmit oral, respiratory, and genital infections from one site in body to the other. Oral health has a direct correlation on the transmission of infection; a cut in the mouth, bleeding gums, lip sores or broken skin increases chances of life-threatening infections. Although oral sex is considered a low risk activity, it is important to use protection such as physical barriers, health and medical issues, ethical issues, and oral hygiene and dental issues. The ulcerations or unhealthy periodontium in mouth accelerates the phenomenon of transmission of infections into the circulation. Thus, consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

    Oral somatosensory awareness refers to the somatic sensations arising within the mouth, and to the information these sensations provide about the state and structure of the mouth itself, and objects in the mouth. Because the oral tissues have a strong somatosensory innervation, they are the locus of some of our most intense and vivid bodily experiences. The salient pain of toothache, or the habit of running one's tongue over one's teeth when someone mentions "dentist", provide two very differ...

    This article focused on the approach to oral and esophageal disorders in patients with AIDS. Most of these disorders respond to various therapeutic regimens. Some of the oral complications can be prevented with dental prophylaxis, whereas recurrent esophageal disease in some patients may require long-term suppressive therapy. As patients with AIDS live longer with lower CD4 counts, gastroenterologists need to become familiar with the approach to and management of the more common lesions of the mouth and esophagus.

    Pigmentations are commonly found in the mouth. They represent in various clinical patterns that can range from just physiologic changes to oral manifestations of systemic diseases and malignancies. Color changes in the oral mucosa can be attributed to the deposition of either endogenous or exogenous pigments as a result of various mucosal diseases. The various pigmentations can be in the form of blue/purple vascular lesions, brown melanotic lesions, brown heme-associated lesions, gray/black pigmentations.

  9. Maintaining women's oral health.

    Science.gov (United States)

    McCann, A L; Bonci, L

    2001-07-01

    Women must adopt health-promoting strategies for both general health and the oral cavity, because the health of a woman's body and oral cavity are bidirectional. For general health-maintenance strategies, dental practitioners should actively advise women to minimize alcohol use, abstain from or cease smoking, stay physically active, and choose the right foods to nourish both the body and mind. For oral health-maintenance strategies, dental practitioners should advise women on how to prevent or control oral infections, particularly dental caries and periodontal diseases. Specifically, women need to know how to remove plaque from the teeth mechanically, use appropriate chemotherapeutic agents and dentifrices, use oral irrigation, and control halitosis. Dental practitioners also need to stress the importance of regular maintenance visits for disease prevention. Adolescent women are more prone to gingivitis and aphthous ulcers when they begin their menstrual cycles and need advice about cessation of tobacco use, mouth protection during athletic activities, cleaning orthodontic appliances, developing good dietary habits, and avoiding eating disorders. Women in early to middle adulthood may be pregnant or using oral contraceptives with concomitant changes in oral tissues. Dental practitioners need to advise them how to take care of the oral cavity during these changes and how to promote the health of their infants, including good nutrition. Older women experience the onset of menopause and increased vulnerability to osteoporosis. They may also experience xerostomia and burning mouth syndrome. Dental practitioners need to help women alleviate these symptoms and encourage them to continue good infection control and diet practices.

  10. Oral vs. salivary diagnostics

    Science.gov (United States)

    Marques, Joana; Corby, Patricia M.; Barber, Cheryl A.; Abrams, William R.; Malamud, Daniel

    2015-05-01

    The field of "salivary diagnostics" includes studies utilizing samples obtained from a variety of sources within the oral cavity. These samples include; whole unstimulated saliva, stimulated whole saliva, duct saliva collected directly from the parotid, submandibular/sublingual glands or minor salivary glands, swabs of the buccal mucosa, tongue or tonsils, and gingival crevicular fluid. Many publications state "we collected saliva from subjects" without fully describing the process or source of the oral fluid. Factors that need to be documented in any study include the time of day of the collection, the method used to stimulate and collect the fluid, and how much fluid is being collected and for how long. The handling of the oral fluid during and post-collection is also critical and may include addition of protease or nuclease inhibitors, centrifugation, and cold or frozen storage prior to assay. In an effort to create a standard protocol for determining a biomarker's origin we carried out a pilot study collecting oral fluid from 5 different sites in the mouth and monitoring the concentrations of pro- and anti-inflammatory cytokines detected using MesoScaleDiscovery (MSD) electrochemiluminesence assays. Our data suggested that 3 of the cytokines are primarily derived from the submandibular gland, while 7 of the cytokines come from a source other than the major salivary glands such as the minor salivary glands or cells in the oral mucosae. Here we review the literature on monitoring biomarkers in oral samples and stress the need for determining the blood/saliva ratio when a quantitative determination is needed and suggest that the term oral diagnostic be used if the source of an analyte in the oral cavity is unknown.

  11. Oral and systemic photoprotection.

    Science.gov (United States)

    Chen, Andrew C; Damian, Diona L; Halliday, Gary M

    2014-01-01

    Photoprotection can be provided not only by ultraviolet (UV) blockers but also by oral substances. Epidemiologically identified associations between foods and skin cancer and interventional experiments have discovered mechanisms of UV skin damage. These approaches have identified oral substances that are photoprotective in humans. UV inhibits adenosine triphosphate (ATP) production causing an energy crisis, which prevents optimal skin immunity and DNA repair. Enhancing ATP production with oral nicotinamide protects from UV immunosuppression, enhances DNA repair and reduces skin cancer in humans. Reactive oxygen species also contribute to photodamage. Nontoxic substances consumed in the diet, or available as oral supplements, can protect the skin by multiple potential mechanisms. These substances include polyphenols in fruit, vegetables, wine, tea and caffeine-containing foods. UV-induced prostaglandin E2 (PGE2 ) contributes to photodamage. Nonsteroidal anti-inflammatory drugs and food substances reduce production of this lipid mediator. Fish oils are photoprotective, at least partially by reducing PGE2 . Orally consumed substances, either in the diet or as supplements, can influence cutaneous responses to UV. A current research goal is to develop an oral supplement that could be used in conjunction with other sun protective strategies in order to provide improved protection from sunlight.

  12. Melatonin and oral cavity.

    Science.gov (United States)

    Cengiz, Murat İnanç; Cengiz, Seda; Wang, Hom-Lay

    2012-01-01

    While initially the oral cavity was considered to be mainly a source of various bacteria, their toxins and antigens, recent studies showed that it may also be a location of oxidative stress and periodontal inflammation. Accordingly, this paper focuses on the involvement of melatonin in oxidative stress diseases of oral cavity as well as on potential therapeutic implications of melatonin in dental disorders. Melatonin has immunomodulatory and antioxidant activities, stimulates the proliferation of collagen and osseous tissue, and acts as a protector against cellular degeneration associated with aging and toxin exposure. Arising out of its antioxidant actions, melatonin protects against inflammatory processes and cellular damage caused by the toxic derivates of oxygen. As a result of these actions, melatonin may be useful as a coadjuvant in the treatment of certain conditions of the oral cavity. However, the most important effect of melatonin seems to result from its potent antioxidant, immunomodulatory, protective, and anticancer properties. Thus, melatonin could be used therapeutically for instance, locally, in the oral cavity damage of mechanical, bacterial, fungal, or viral origin, in postsurgical wounds caused by tooth extractions and other oral surgeries. Additionally, it can help bone formation in various autoimmunological disorders such as Sjorgen syndrome, in periodontal diseases, in toxic effects of dental materials, in dental implants, and in oral cancers.

    We investigated age-26 personality characteristics and age-32 oral health in a prospective study of a complete birth cohort born in Dunedin, New Zealand. Personality was measured using the Multidimensional Personality Questionnaire (MPQ). Oral health was measured using the short-form Oral Health Impact Profile (OHIP-14), a global measure, and dental examinations. Personality profiles were constructed for 916 individuals (50.8% men) using standardized MPQ scores, and multivariate analyses examined their association with oral health. Those reporting 1+ OHIP-14 impacts had higher Negative Emotionality scores (and lower Constraint and Positive Emotionality MPQ superfactor scores) than those who did not. After controlling for gender, clinical status, and the other two MPQ superfactors, those scoring higher on Negative Emotionality had a greater risk of reporting 1+ OHIP-14 impacts, as well as 3+ OHIP-14 impacts and worse-than-average oral health. They also had a greater risk of having lost at least one tooth from caries and of having 3+ decayed surfaces. Personality characteristics appear to shape self-reports of oral health. Personality is also a risk factor for clinical disease status, at least with respect to dental caries and its sequelae. Because the attitudes and values tapped into by personality tests can be altered by brief cognitive interventions, those might be useful in preventive dentistry. PMID:21896053

    Bilingual text corresponding analysis can help bridge the language barrier of cross-lingual corpora. Cross-lingual latent semantic indexing corpus-based does not fully take into account bilingual semantic relationship. The paper proposes a new method building semantic relationship of bilingual parallel document via partial least squares. In this method, the parallel documents are viewed as two different lingual representations for the same semantic content, such that, a unify latent semantic space can be constructed for two languages. The task of cross-lingual text categorization is performed in the new bilingual latent semantic spaces. The Chinese-English document-aligned dataset for evaluating is collected from the Hong Kong government news website. Experimental results on the task of mono-and cross-lingual classification show that performance of the presented method is over or near to mono-lingual classification in the original feature spaces.%双语文本对应分析在处理多语言文本数据、克服语言障碍等方面有着重要的作用,基于语料库技术的跨语言潜在语义索引方法没有充分考虑双语的语义相关性.本文将双语平行文档看作同一语义内容的两种语言表达,运用偏最小二乘方法构建双语文本的语义相关性,为每种语言建立单独的潜在语义空间,并在这两个空间上实现跨语言的分类任务.在香港政府网中英双语新闻的实验结果显示,本文方法构造的双语潜在语义空间上完成的跨语言和单语言文本分类性能接近或优于原始特征空间的单语言分类,并具有良好的稳健性.

    Human papillomavirus (HPV) is strictly epitheliotropic, infecting stratified squamous cutaneous and mucosal epithelial cells. Oral HPV infection may be subclinical or putatively associated with benign or malignant oral neoplasms. The benign HPV-associated oral lesions, focal epithelial hyperplasia (Heck disease), oral squamous cell papilloma, oral verruca vulgaris (common wart) and oral condyloma acuminatum, are collectively referred to as oral warts. Oral warts are usually asymptomatic, may be persistent or uncommonly, may regress spontaneously. HPV-associated oral warts have a prevalence of 0.5% in the general population, occur in up to 5% of HIV-seropositive subjects, and in up to 23% of HIV-seropositive subjects on highly active antiretroviral therapy. This paper is a clinico-pathological review of HPV-associated oral warts.

    Full Text Available INTRODUCTION: Oral Myiasis, a condition of infestation of the body by fly larvae (maggots is a rare pathology in humans. It is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis. It is seen frequently in tropical countries and hot climatic regions. The reported cases in literature of oral Myiasis associated with oral cancer are few. The treatment is a mechanical removal of the maggots but a systemic treatment with Ivermectin, a semi - synthetic macrolide antibiotic, has been used successfully for treatment for oral m yiasis. We present a case of 55 yr old male alcoholic patient with oral myiasis with extensive proliferative growth of oral cavity. Our patient was managed with manual debridement and administration of systemic ivermect in along with antibiotic coverage. Incisional biopsy of the proliferative lesion showed well differentiated squamous cell carcinoma. Thus our patient showed presence of oral myiasis in association with oral squamous cell carcinoma.

    In addition to tobacco and alcohol consumption, the two main risk factors for oral squamous cell carcinoma (OSCC), recent studies have revealed infections with human papilloma virus (HPV) as an additional risk factor for OSCC development. In the field of head and neck malignancies, the prevalence of HPV infections in oropharyngeal cancer (OC) ranges in different studies up to 84%. While HPV infection is discussed as an independent risk factor in this region, its distinguished role in carcinogenesis of tumours localized to the oral cavity remains still uncertain. In this study, we analysed the HPV status in 88 consecutive patients with OSCCs localized anterior of the palatoglossal arch who were treated in the Department of Oral and Maxillofacial Surgery at the University Medical Center Mainz. The HPV status analysis was performed using DNA-PCR and immunostaining of p16 protein. The prevalence of HPV-positive OSCCs was about 6% (5 patients). In 3 patients the HPV subtypes 16/18 were found. No significant differences between the HPV positive and negative patients regarding age, gender, smoking and alcohol consumption, localization and TNM level could be detected. Contrary to other studies focussing on cancers of the lingual and palatine tonsil, the prevalence of HPV infections was much lower in the oral cavity. Therefore HPV infection might play a less important role in oral carcinogenesis.

    Acid-producing microorganisms are base etiological agents of lesions of tooth enamel and destruction of dentin. The process start by specific microflora of tooth deposit--Streptococcus mutans, Lactobacteria and Actinomycetis viscosus which ferment food carbogydrate to form acids. High titre of them in oral cavity may be considered like a marker of carbohydrate food. But the pathogenic bacteria don't have aggression to host organism until they will have virulent factors which help to get over protection of host organism. At the same time, microflora of oral cavity is involved to form pellicula. Pellicula is a biofilm which to protect tooth enamel and dentin. Understanding relationships between safety factors of host and pathogenic microflora of oral cavity will give to create effective methods of prevention and treatment.

    2010-01-01

    Full Text Available Pyogenic granuloma is one of the inflammatory hyperplasias seen in the oral cavity. This term is a misnomer because the lesion is unrelated to infection and in reality arises in response to various stimuli such as low-grade local irritation, traumatic injury, or hormonal factors. It predominantly occurs in the second decade of life in young females, possibly because of the vascular effects of female hormones. Clinically, oral pyogenic granuloma is a smooth or lobulated exophytic lesion manifesting as small, red erythematous growth on a pedunculated or sometimes sessile base, which is usually hemorrhagic. Although excisional surgery is the treatment of choice , some other treatment protocols such as the use of Nd:YAG laser, flash lamp pulsed dye laser, cryosurgery, intralesional injection of ethanol or corticosteroids, and sodium tetradecyl sulfate sclerotherapy have been proposed. We present the case of a 25-year-old pregnant woman with large oral pyogenic granuloma.

  3. Oral heparin: status review

    Gomez-Orellana Isabel

    2006-05-01

    Full Text Available Abstract Unfractionated heparin and low molecular weight heparin are the most commonly used antithrombotic and thromboprophylactic agents in hospital practice. Extended out-of-hospital treatment is inconvenient in that these agents must be administered parenterally. Current research is directed at development of a safe and effective oral antithrombotic agent as an alternative for the effective, yet difficult to use vitamin K antagonists. A novel drug delivery technology that facilitates transport of drugs across the gastrointestinal epithelium has been harnessed to develop an oral dosage form of unfractionated heparin. Combining unfractionated heparin with the carrier molecule, sodium N-(8 [2-hydroxybenzoyl]amino caprylate, or SNAC has markedly increased the gastrointestinal absorption of this drug. Preclinical and clinical studies to-date suggests that oral heparin-SNAC can confer a clinical efficacious effect; further confirmation is sought in planned clinical trials.

    Divers can have several oral problems. Firstly, problems caused by pressure changes. These are barodontalgia and odontocrexis. Barodontalgia is toothache by barotrauma. Odontocrexis is restorations coming lose or breaking or tooth fractures by expansion of air beneath restorations. Other problems can occur by cements used to fix casted restorations, by inflammations in the orofacial region, and by not yet fully healed oral wounds. Secondly, there are problems related to the diver's mouthpiece. To keep the mouthpiece in place, the mandible has to be forced in a forward position. Holding this position often and for long periods of time, may develop or aggravate temporomandibular dysfunction. Insufficient fit of the mouthpiece may induce oral mucosal lesions. Therefore, it is recommended to produce individual diver mouthpieces. It is also recommended to produce individual diver mouthpieces for complete dentures wearing divers and for divers with fixed orthodontic appliances.

    The oral cavity can be affected by a wide variety of disorders characterized by inflammation of the gingiva and/or oral mucosa. In dogs and cats, differential diagnoses for generalized oral inflammatory disorders include plaque-reactive mucositis, chronic gingivostomatitis, eosinophilic granuloma complex, pemphigus and pemphigoid disorders, erythema multiforme, and systemic lupus erythematosus. In addition, endodontic or periodontal abscesses, infectious conditions, reactive lesions, and neoplastic conditions may initially present with localized or generalized inflammation of the oral mucosa. Determination of the underlying cause of an oral inflammatory condition relies on a thorough history, complete physical and oral examination, and incisional biopsy and histopathologic examination of lesions.

The rationale for molecular-targeted prevention of oral cancer is promising. Biomarkers of genomic instability, including aneuploidy and allelic imbalance, are possible to measure the cancer risk of oral premalignancies. Understanding of the biology of oral carcinogenesis will yield important advances for detecting high-risk patients, monitoring preventive interventions, and assessing cancer risk and pharmacogenomics. In addition, novel chemopreventive agents based on molecular mechanisms and targets against oral cancers will be derived from studies using appropriate animal carcinogenesis models. New approaches, such as molecular-targeted agents and agent combinations in high-risk oral individuals, are undoubtedly needed to reduce the devastating worldwide consequences of oral malignancy.

    This randomized, evaluator-masked, controlled study evaluates the effectiveness of oral in contrast to written instruction of oral hygiene. Eighty-three students without clinical signs of periodontitis were randomly assigned to either a control group or one of three experimental conditions: 1) written instruction, 2) standardized oral instruction, or 3) individualized oral instruction. Plaque and bleeding indices were assessed to analyze intervention effects on oral health and oral hygiene skills. Measurements took place at baseline and 4 weeks after intervention. Groups differed significantly with respect to gingival bleeding and were tentatively significant with respect to oral hygiene skills. Participants who had received oral individualized instructions showed the best results. A gradient of effectiveness of the instruction methods was observed with most favorable results for the individualized instruction.

    Full Text Available La paracoccidioidomicosis (PCM o blastomicosis suramericana es la micosis sistémica más importante de América latina que es relativamente común en Brasil, Venezuela, Colombia, Ecuador y Argentina. Los casos esporádicos también pueden verse en algunos otros países, la cual es progresiva y con un infrecuente desenlace fatal si no es tratada a tiempo. Se considera como una enfermedad multifocal, con lesiones orales como la característica prominente. Es causada por un hongo dimórfico, Paracoccidioides brasiliensis, que afecta principalmente la piel, los ganglios linfáticos, los pulmones y membranas mucosas oral, nasal y gastrointestinal. Dependiendo de la inmunidad específica del huésped, la infección puede asumir muchas formas y afecta a uno o varios órganos, llegando a ser una enfermedad grave y potencialmente fatal. Es muy importante para los profesionales de la salud de todo el mundo tener conocimiento acerca de la Paracoccidioidomicosis porque a veces la enfermedad sólo se manifiesta muchos años después de que haya abandonado la zona endémica. Para proporcionar información útil sobre el diagnóstico y tratamiento de la enfermedad se presenta caso clínico de un paciente masculino de 48 años de edad procedente de una zona rural de Juramento Brasil, por presentar múltiples úlceras dolorosas en encía y paladar de 3 meses de evolución; refiere antecedentes de fumador crónico, al examen clínico extraoral se descartan lesiones en otros órganos y al examen intraoral se observan múltiples úlceras con fondo necrótico y granulomatoso localizadas en encía y paladar. Se realizó una biopsia incisional de la lesión y el material fue enviado para estudio anatomopatológico. El informe histopatológico confirmó la impresión clínica de Paracoccidioidomicosis. El paciente fue tratado con el uso de sulfametoxazol + trimetoprima - 800/60 mg/día, vía oral, cada 12 horas durante 30 días. Las lesiones bucales desaparecieron

    An important question in research about bilingualism is whether translation from a second language (L2) to the native language (L1) is semantically mediated or whether it occurs through word associations at the lexical level. Recent research has shown that both L1 and L2 number word translation imply semantic access, suggesting strong L2 lexicosemantic mappings for number words (Duyck & Brysbaert, 2004). In the present study, this assumption was further explored by means of a cross-lingual number distance priming paradigm with Dutch-English-French trilinguals. We found that number word translation from L1 to the third language (L3), and vice versa, was facilitated by L2 number masked word primes that represented the same magnitude as the target (translation equivalents), relative to primes that are numerically less close. This confirms the existence of strong L2 lexicosemantic mappings for number words and generalizes previous semantic effects in L1-L2 translation to translation processes between L1 and L3.

    The experience of childhood maltreatment is related to an increased risk of developing a variety of psychiatric disorders, as well as a change in the structure of the brain. However, not much is known about the neurobiological basis of resilience to childhood maltreatment. This study aims to identify resting-state functional connectivity (RSFC) patterns specific for resilience to childhood maltreatment, focusing on the default mode and salience network and networks seeded from the amygdala and left dorsomedial prefrontal cortex. Resting-state functional MRI scans were obtained in 33 individuals. Seeds in the bilateral amygdala, the dorsal anterior cingulate cortex (dACC), the posterior cingulate cortex and the left dorsomedial prefrontal cortex were defined and used to examine whether resilient individuals differed from vulnerable individuals and healthy controls in RSFC with other brain regions. Within the salience network, the resilient group was associated with increased RSFC between the left dACC and a region containing the bilateral lingual gyrus and the occipital fusiform gyrus compared to both the vulnerable group and the healthy controls. In this study, we found RSFC patterns specific for resilient individuals. Regions that are implicated are related on a functional level to declarative memory and the processing of emotional stimuli.

    The fetal anatomy of the human epiglottis has not yet been fully described. We investigated the histology (paraffin-embedding) of 18 mid-term fetuses at 7-25 weeks of gestation (three fetuses each at 7, 9, 12, 15, 20 and 25 weeks). A mesenchymal condensation of the epiglottic cartilage appears posterior and somewhat superior to the hyoid body at 9 weeks, but at 12 and 15 weeks, the root or inferior part descends to the level of the thyroid cartilage. The covering epithelium stains much darker with hematoxylin than other pharyngeal epithelia. After 20 weeks, the epiglottis again protrudes superiorly beyond the hyoid body. In contrast to other laryngeal cartilage anlagen, the mesenchymal condensation of the epiglottis begins to express glial fibrillary acidic protein (GFAP) at 15 weeks. At the same stage, mucosal glands begin invading into the epiglottic mesenchyme. The developing cartilage becomes penetrated and fragmented by abundant mucosal glands up until 25 weeks. The thyro-epiglottic ligament seems to develop from the GFAP-positive mesenchymal condensation, whereas the hyo-epiglottic ligament is likely to originate from the fasciae of lingual muscles. Epithelial-mesenchymal interaction is strongly suggested in the development of the epiglottic cartilage and concomitant glands.

    Speech communication can be viewed as an interactive process involving a functional coupling between sensory and motor systems. One striking example comes from phonetic convergence, when speakers automatically tend to mimic their interlocutor's speech during communicative interaction. The goal of this study was to investigate sensory-motor linkage in speech production in postlingually deaf cochlear implanted participants and normal hearing elderly adults through phonetic convergence and imitation. To this aim, two vowel production tasks, with or without instruction to imitate an acoustic vowel, were proposed to three groups of young adults with normal hearing, elderly adults with normal hearing and post-lingually deaf cochlear-implanted patients. Measure of the deviation of each participant's f0 from their own mean f0 was measured to evaluate the ability to converge to each acoustic target. showed that cochlear-implanted participants have the ability to converge to an acoustic target, both intentionally and unintentionally, albeit with a lower degree than young and elderly participants with normal hearing. By providing evidence for phonetic convergence and speech imitation, these results suggest that, as in young adults, perceptuo-motor relationships are efficient in elderly adults with normal hearing and that cochlear-implanted adults recovered significant perceptuo-motor abilities following cochlear implantation.

  20. Passive restriction of blood flow and counter-current heat exchange via lingual retia in the tongue of a neonatal gray whale Eschrichtius robustus (Cetacea, Mysticeti).

    Retia mirabilia play broad roles in cetacean physiology, including thermoregulation during feeding and pressure regulations during diving. Vascular bundles of lingual retia are described within the base of the tongue of a neonatal female gray whale (Eschrichtius robustus). Each rete consists of a central artery surrounded by four to six smaller veins. The retia and constituent vessels decrease in diameter as they extend anteriorly within the hyoglossus muscle from a position anterior to the basihyal cartilage toward the apex of the tongue. The position of the retia embedded in the hyoglossus and the anterior constriction of the vessels differs from reports of similar vascular bundles that were previously identified in gray whales. The retia likely serve as a counter-current heat exchange system to control body temperature during feeding. Cold blood flowing toward the body center within the periarterial veins would accept heat from warm blood in the central artery flowing toward the anterior end of the tongue. Although thermoregulatory systems have been identified within the mouths of a few mysticete species, the distribution of such vascular structures likely is more widespread among baleen whales than has previously been described. © 2015 Wiley Periodicals, Inc.
