Summary: The aim was to determine predictors for the development of complaints of temporomandibular disorders (TMD) in a large sample of Dutch scuba divers who were free of any TMD complaints before they started diving actively. Five-hundred and thirty-six scuba divers (mean ± SD age = 40·4 ± 11·9 years; 34·1% women) completed a specifically developed questionnaire, either online or on paper. Stepwise forward logistic regression analysis was performed to predict the presence of TMD pain, with several potential risk factors as predictors. Four hundred and eighty-five of the 536 respondents were free of any TMD pain before they started diving actively. In this sample, TMD pain was present in 214 persons (44·1%). Four predictors contributed significantly to the presence of TMD pain, viz., clenching (OR = 2·466), warm water (OR = 1·685), biting on the mouthpiece (OR = 1·598), and the quality rating of the mouthpiece (OR = 0·887, that is, a higher rating means a smaller odds of having TMD pain). TMD pain is a common complaint among scuba divers who were free of such complaints before they started diving actively. Clenching, biting on the mouthpiece, and a low rating of the mouthpiece are predictors for the presence of TMD pain in scuba divers, while diving in cold water serves as a protective factor for TMD pain. © 2014 John Wiley & Sons Ltd.

Approximately 50%of children under the age of 15 are victims of various kinds of injuries in the orofacial region. Post-traumatic complications may occur, including crown discolouration, cervical root fracture, ankylosis, root resorption and tooth loss. The most severe complication after dental injury in primary dentition can affect the developing permanent tooth germ, and various consequences may be seen several years later when the permanent tooth erupts. In the permanent dentition, the most severe dental injury affects the surrounding alveolar bone structure and will lead to loss of the tooth. Current literature emphasises that awareness of appropriate triage procedures following dental trauma is unsatisfactory and that delay in treatment is the single most influential factor affecting prognosis. What should a paediatrician know, and more importantly, how should he/she advise parents and caretakers? In an emergency situation such as tooth avulsion, reimplantation within 30 min is the best treatment option at the site of the accident. If reimplantation of the tooth is impossible, milk, saline or even saliva are the preferred transport media. The prognosis for an avulsed tooth depends upon prompt care, which is a determinant factor for successful treatment of the traumatised tooth. In all other dental trauma cases, it is important to refer the child to a paediatric dentist, to follow up the healing process and reduce late post-traumatic complications. With timely interventions and appropriate treatment, the prognosis for healing following most dental injuries is good. In conclusion, it is important that paediatricians are able to inform parents and caretakers about all possible and long-lasting consequences of different dental injuries. © Springer-Verlag 2009.

Excessive gingival display (EGD) is a condition in which an overexposure of the maxillary gingiva (>3 mm) is present during smiling. The proper diagnosis and determination of its etiology are essential for the selection of the right treatment modality. Different techniques have been used in cases of hyperactive upper lip: botulinum toxin injections, lip elongations with rhinoplasties, lip muscle detachments, myotomies, and lip repositions. This report presents a case of a young woman with an EGD larger than 10 mm during smiling caused by altered passive eruption, vertical maxillary excess, and a hyperactive upper lip that was treated with a modified lip repositioning technique and laser gingivectomy because she strongly refused orthognathic surgical treatment. A novel addition to the technique is proposed, a reversible trial accomplished just by applying sutures on the borders of the future split-thickness flap, marked using diode laser, before starting the flap incision. © 2014 American Association of Oral and Maxillofacial Surgeons.

Abstract The aim of this study was to evaluate the two-dimensional (2D) and three-dimensional (3D) changes in the pharyngeal airway space (PAS) in 20 class III patients who underwent mono- or bimaxillary surgery using cone-beam computed tomography (CBCT). CBCT examination was obtained before surgery (T1) and at least 3 months after surgery (T2). The pharyngeal airway of each patient was studied at three levels: the level of the posterior nasal spine, the level of the most inferior point of the soft palate, and the level of the top of the epiglottis. At each of these levels, the anteroposterior and lateral dimension as well as cross-sectional area were measured. The volume of the whole PAS and volume between each cross section were also measured. The area and anteroposterior dimensions at the level of the most inferior point of the soft palate significantly decreased in patients who underwent monomaxillary surgery. The volume of the PAS decreased in both groups, but decreased significantly only in the monomaxillary group. The upper volume decreased in the mono- and increased in the bimaxillary group. The lower volume significantly decreased in the monomaxillary group. However, results showed that PAS decreased more after mono-than after bimaxillary surgery. © 2015 European Association for Cranio-Maxillo-Facial Surgery. Source

Objective: The aim of this study was to determine the prevalence of oral mucosal lesions in institutionalized elderly people in Mashhad, northeast of Iran. Background: This study was conducted to assess the prevalence of oral lesions in the institutionalized elderly. Methods: In this survey, we studied all of the nursing homes in Mashhad; a total of five encompassing 237 residents. The subjects were examined and lesions recorded in a designed checklist. T-test, chi-square and Fisher's exact tests were used for the analysis. Results: The mean age of the patients was 79.59 ± 8.88. Ninety-eight per cent of cases had at least one oral mucosal lesion. The most common lesions were fissured tongue (66.5%), atrophic glossitis (48.8%), sublingual varicosity (42%) and xerostomia (38%). There was no significant difference in the prevalence of denture-related lesions (DRLs) between men and women (p > 0.05). Xerostomia was more prevalent in 70-79-year-old than in 60-69-year-old subjects. No case of oral malignant lesion was detected. Discussion: These findings revealed a higher prevalence of oral mucosal lesions in Mashhad city compared with other studies conducted in other major cities in Iran and abroad. The results emphasise the necessity of national programmes towards oral health promotion. © 2011 The Gerodontology Society and John Wiley & Sons A/S. Source
