BACKGROUND AND OBJECTIVES: Temporomandibular disorder is considered to be a set of clinical manifestations that affect the masticatory muscles, the temporomandibular joint and adjacent structures, whose signs and symptoms can negatively impact the quality of life of their patients. A population group in which the prevalence of temporomandibular disorder has increased in recent years is that of athletes. The aim of the present study was to conduct an integrative literature review to verify the prevalence of temporomandibular disorders in athletes, as well as factors related to their predisposition. CONTENTS: The searches were performed in the Medline, LILACS and Scielo databases, using the descriptors “temporomandibular joint”, “athletic injuries” and “temporomandibular disease”. Inclusion criteria were researches derived from primary data regardless of design, which was the target audience of athletes and that addressed the presence of temporomandibular joint or muscle dysfunction. Ten studies were selected and included in the review. The results obtained with the analysis of these articles showed that athletes are subject to temporomandibular disorders not only due to injuries suffered during competitions, but also due to factors associated with stress and the use of specific devices for sports practice. CONCLUSION: The occurrence of temporomandibular disorders is common among athletes, but can be avoided with the use of preventive measures and conservative treatments. Dental monitoring is essential for these professionals to perform well, preventing the occurrence of temporomandibular disorders or treating them when they occur. RESUMO JUSTIFICATIVA E OBJETIVOS: A disfunção temporomandibular é considerada um conjunto de alterações que acometem os músculos mastigatórios, articulação temporomandibular e estruturas adjacentes, os quais podem impactar negativamente na qualidade de vida dos seus portadores. Um grupo populacional no qual a prevalência de disfunção temporomandibular tem aumentado nos últimos anos é o de atletas. Assim, o objetivo do presente estudo foi realizar uma revisão integrativa da literatura a fim de verificar a prevalência das disfunções temporomandibulares em atletas, bem como os fatores relacionados a sua predisposição. CONTEÚDO: As buscas foram realizadas nas bases de dados Medline, LILACS e Scielo, utilizando os descritores “temporomandibular joint”, “athletic injuries” e “temporomandibular disease”. Os critérios de inclusão foram pesquisas oriundas de dados primários com qualquer delineamento; tendo como público-alvo os atletas e que abordassem a presença de disfunção temporomandibular articular ou muscular. Foram selecionados 10 estudos que foram incluídos nesta revisão. Os resultados obtidos com as análises dos artigos evidenciaram que atletas estão sujeitos às disfunções temporomandibulares não somente pelas lesões sofridas durante as competições, mas também por fatores associados ao estresse e ao uso de dispositivos específicos da prática desportiva. CONCLUSÃO: A ocorrência de disfunções temporomandibulares é comum entre atletas, mas elas podem ser evitadas com a utilização de medidas preventivas e tratamentos conservadores. O acompanhamento odontológico é fundamental para prevenir ou tratar a disfunção temporomandibular.

BAKGROUND AND OBJECTIVES: Arthralgia is a common complaint among patients with temporomandibular osteodegeneration, however, for the accurate diagnosis of osteodegeneration, it is suggested the adoption of imaging tests associated with standardized clinical diagnosis protocols. The objective of this study was to evaluate patients with degenerative changes in the temporomandibular joint previously visualized by cone beam computed tomography, relating these changes with the clinical diagnoses and symptoms of temporomandibular disorders, in order to conclude which of the degenerative changes develop more painful symptomatology. METHODS: A cross-sectional observational descriptive study. Thirty-eight patients who had previously done the cone beam computed tomography exam were evaluated. Subjects were grouped according to clinical diagnosis of temporomandibular joint changes using the Research Diagnostic Criteria for Temporomandibular Disorders questionnaire. The presence of pain was considered during lateral palpation; intra-articular palpation; excursive movements; and active mouth opening. RESULTS: Among the purely clinical diagnoses, only 10.5% were conclusive, classifying patients as suffering from osteoarthritis/osteoarthrosis. Painful joint symptoms were found in all groups, with no statistically significant difference. Similarly, the presence of degenerative disorders, including flattening, osteophytes, sclerosis, and erosion were found in similar proportions in all diagnosis groups. CONCLUSION: 89.5% of the degenerative changes were clinically underdiagnosed. There was a positive association between the presence of symptoms and the number of correct clinical diagnoses of osteoarthritis/osteoarthrosis obtained with the Research Diagnostic Criteria for Temporomandibular Disorders.

BACKGROUND AND OBJECTIVES: Arthrocentesis is an effective treatment to reduce or eliminate pain, increase maximal interincisal distance, and to eliminate joint effusion in patients with disc displacement without reduction. This study aims to expose and to discuss a new technique proposal of temporomandibular joint arthrocentesis applied in the treatment of a single case of disc displacement without reduction. CASE REPORT: Female patient, 18-year-old patient sought treatment due to joint pain and mouth opening limitation. The maximal interincisal distance was 30.28mm. Magnetic resonance imaging confirmed the diagnosis of disc displacement without reduction with signs of joint effusion in the right temporomandibular joint. Temporomandibular joint arthrocentesis was performed under selective sensory nerve block of the auriculotemporal, the masseteric and posterior deep temporal nerves. Two needles were inserted in the upper compartment of the temporomandibular joint. In the second needle, a transparent catheter was connected into a vacuum pump. Clinically, after the arthrocentesis, the maximal interincisal distance increased to 46.25mm, and the patient referred no more pain. After six months, a magnetic resonance imaging was performed to observe the results, and there were no more signs of joint effusion. CONCLUSION: Temporomandibular joint arthrocentesis was an effective treatment for this patient with disc displacement without reduction. The aspect of this technique that is particularly relevant for clinical practice was the connection of a transparent catheter to a vacuum pump. In fact, it allowed the visualization of the solution fluidity, as well as guides the flow of the solution used for joint washing, optimizing the irrigation. However, new studies are necessary to compare different protocols of irrigation with and without the associated use of a vacuum pump.

JUSTIFICATIVA E OBJETIVOS: A dor aguda pós-operatória de terceiros molares requer não somente habilidade do cirurgião- -dentista em removê-los, mas também no correto controle farmacológico desse quadro álgico que se instalará após o efeito do bloqueio anestésico ter cessado. O objetivo deste estudo foi relatar um caso de dor moderada pós-procedimento de remoção de terceiros molares, em que os efeitos adversos do fármaco prescrito foram determinantes para o abandono do tratamento farmacológico e consequentemente da manutenção da dor. RELATO DO CASO: Paciente do sexo masculino, 22 anos, estudante, natural de Curitiba, procurou atendimento ambulatorial por queixa de dor aguda de moderada intensidade, após 48 horas da remoção dos terceiros molares. Apresentou efeitos adversos devido à prescrição da associação de codeína (30mg) e paracetamol (325mg) por via oral de 6/6 horas. Frente a isso, optou-se pela prescrição de hidroxibenzoato de viminol (70mg) por via oral de 6/6 horas. CONCLUSÃO: A prescrição do analgésico hidroxibenzoato de viminol resultou em completa, rápida e eficaz analgesia pós-operatória, com excelente tolerabilidade. BACKGROUND AND OBJECTIVES: Acute postoperative pain of the third molars requires not only the ability of the dental surgeon in removing them but also the correct pharmacological control of this incidental pain that will install after the effect of the anesthetic blockade has ceased. The objective of this study was to report a case of moderate pain after third molar removal procedure, where the adverse effects of the prescribed medication were determinant for the abandonment of pharmacological treatment and consequently the maintenance of the pain. CASE REPORT: A 22-year-old male patient, student, from the city of Curitiba, sought outpatient care for acute moderate-intensity pain after 48 hours of removal of the third molars. He was experiencing some adverse effects due to the prescription of the combination of oral codeine (30mg) and paracetamol (325mg) at every 6 hours. In view of this, we opted for the prescription of viminol hydroxybenzoate (70mg) orally, every 6 hours. CONCLUSION: The prescription of the viminol hydroxybenzoate analgesic resulted in complete, rapid and effective postoperative analgesia, with excellent tolerability.
