Fixed mandibular propulsion appliances are an alternative for the treatment of Class II malocclusion in individuals with mandibular deficiency. Since they are fixed appliances, said devices keep the mandible in an anterior-forced position during rest and during all mandibular functions. When a propulsive appliance is used, the lower jaw is displaced forward and downward. This movement leads to a new position of the condyle, which can, ultimately affect the normal functioning of the temporomandibular joint (TMJ). The aim of this paper was to review effects of fixed mandibular propulsive appliance on TMJ. Inclusion criteria considered studies on animals or humans using TMJ radiography, computed tomography, and magnetic resonance imaging. Studies confirm a favorable relation between condyle and glenoid fossa following treatment with fixed mandibular propulsion appliances.

Objective: To assess the attitudes and knowledge about hepatitis by scholars and dental practitioners from Recife and its metropolitan region. Method: The research protocol was submitted and approved by the Ethics and Human Research Committee of the Federal University of Pernambuco. There were included 230 undergraduate students in dentistry and 104 dentists who exercise their professional activity in Recife and its Metropolitan Region. They signed a consent form and answered a questionnaire, the evaluative instrument, with objective questions about biosafety, transmission of hepatitis and sexually transmitted diseases. Results: About the types of hepatitis 133 (57.8%) students and 61 (58.7%) professionals claimed to know the types A, B and C. Concerning transmission 31 (13.5%) students and 25 (24.0%) professionals said that the main route of transmission were sexual and bloodstream respectively. Relating to imunization 221 (96.1%) students and 99 (95.2%) professionals reported that have been vaccinated against hepatitis B, however, only 126 (54.8%) students and 55 (52.9%) professionals have followed the immunization’s schema. Regarding the cleaning of the office equipment, 18.7% of the students replied that they do not know who does it. 56.7% of professionals said that it was performed with alcohol 70 ° GL.Conclusions: The findings indicate that there is a concern for biosafety but the knowledge about the forms of hepatitis transmission and biosecurity measures need to be better settled.

Temporomandibular joint disorders causing limitation of mouth opening and pain may be related to the restriction of slipping or forward displacement of the mandibular condyle. Temporomandibluar arthrocentesis is the lavage of the joint and is regarded as a simple method that produces good results in patients with these symptoms. This article reports a case of disc displacement and closed lock in a patient who reported limited mouth opening and pain as the main symptoms. The treatment proposed was arthrocentesis and lavage, combining a corticosteroid with a sodium hyaluronate solution. It is concluded that arthrocentesis is a simple, efficient and barely invasive method for particular types of temporomandibular joint disorders and should be considered before opting for more invasive surgical procedures.

To determine the prevalence and intensity of orofacial pain in adults that participated in a health program at Ribeirão Preto. Methodology: The study was conducted by a self-administered questionnaire, with 19 questions in 99 people aged 18 to 66 years. The method used for data collection was the index Oral Impacton Daily Performances (OIDP), which evaluated the six months preceding the survey, pain experiences in the mouth, teeth or dentures and how these factors interfere with daily activities. Statistical analysis was performed using Epi Info version 3.4. Results: The majority of the adults who participated in this survey (52.5%) reported having an excellent or good oral health, reported having problems with their teeth (60.6%), no problems with the gums (77.8%), no bad taste in mouth (77.8%) or bad breath (77.8%). Among the participants of the study, 56.6% felt orofacial pain in the last six months and the pain were more frequently caused by cold or hot liquids (30.3%), spontaneous pain (17.2%), during the mouth opening (17.2%), pain in the face (13.1%) and ATM (13.1%). Regarding the severity rate, the highest proportion varied from mild to moderate. Conclusions: Even observing a low severity of orofacial pain, its prevalence was high, which probably has a negative effect on life quality of these people.

Ao paciente é necessário fornecer esclarecimentos sobre as possibilidades terapêuticas, apresentando os riscos, benefícios, prognóstico e custos de cada alternativa possível e indicada. Esta é uma determinação ética e jurídica. Não obstante, o profissional da saúde detém o conhecimento clínico/técnico/científico, e determina quais informações serão (ou não) fornecidas. O paciente decide submeter-se a um tratamento, fornecendo o seu Consentimento Livre e Esclarecido com base nos dados a ele apresentados. Infelizmente, pode ocorrer de alguns profissionais não fornecerem todas as informações necessárias a uma tomada de decisão esclarecida ou, depois de obtido o consentimento do paciente, apresentarem-lhe informação que cause sua desistência do tratamento inicialmente aceito. Esta última informação, se pertinente, e não se tratando de fato superveniente, deveria ter sido fornecida inicialmente. Porém, a informação pode não ser de todo verdadeira, e levar o paciente a decidir baseado, por exemplo, em riscos apresentados e mensurados de forma equivocada. A reabilitação crânio-facial da Articulação Têmporo-Mandibular (ATM), por meio de prótese de ATM, é indicada em muitas situações. Amiúde, pacientes que necessitam de tais próteses apresentam problemas funcionais e estéticos; a expectativa gerada com a reabilitação é grande. Este trabalho apresenta um caso e discute questões éticas e legais, incluindo a responsabilidade civil, do fornecimento parcial e inadequado de esclarecimentos a um paciente.
