Temporomandibular disorders: Guidelines and Self-Care for Patients During COVID-19 Pandemic / Desordem Temporomandibular: Orientações e Autocuidados para Pacientes Durante a Pandemia do COVID-19

Background: Temporomandibular disorder (TMD) belongs to a heterogeneous group of musculoskeletal and neuromuscular conditions involving the temporomandibular joint complex, musculature and adjacent components. These conditions can generate signs and symptoms and be influenced by an altered biopsychosocial condition. Objective: This study aims to seek information to assist the patient in the presence of TMD signs and symptoms and Orofacial Pain, associated with the period of social isolation during the COVID-19 pandemic. Material and methods: For the preparation of this manual, a bibliographic search was performed in the databases PubMed, Latin American and Caribbean Health Sciences Literature (LILACS), BBO (BVS), Scopus, Web of Science and The Cochrane Library, using the keywords: orofacial pain, temporomandibular disorders, bruxism, stress, anxiety, biopsychosocial, diagnosis, self-care with important information on how to reduce and control the signs and symptoms of TMD and Orofacial Pain in this moment of pandemic that we are experiencing a social detachment. Results: The results show that the pandemic of COVID-19 and the need for social isolation, generates psychological impact that raises the pattern of anxiety and can directly affect patients with bruxism and TMD. Conclusion: Psychological factors associated with the pandemic can lead to an increased risk of developing, worsening and perpetuating bruxism, especially waking bruxism and TMD, so dentists should be aware of the occurrence of signs and symptoms to manage the multifactorial aspects of this condition. At that time, individual self-management strategies are advised for the patient, which consist of self-massage techniques, body education, exercise practices, sleep hygiene, meditation also the use of mobile apps and online tools that facilitate this activity.

Introdução: A Desordem Temporomandibular (DTM) pertence a um grupo heterogêneo de condições musculoesqueléticas e neuromusculares envolvendo o complexo articular temporomandibular, a musculatura e os componentes adjacentes. Essas condições podem gerar sinais e sintomas e serem influenciadas por uma condição biopsicossocial alterada. Objetivo: Esse estudo teve como objetivo buscar informações que possam auxiliar ao paciente na presença de sinais e sintomas de DTM e Dor Orofacial associado ao período de isolamento social durante a pandemia do COVID -19. Material e Métodos: Para a elaboração deste manual, foi realizada uma pesquisa bibliográfica nas bases de dados PubMed, Latin American and Caribbean Health Sciences Literature (LILACS), BBO (BVS), Scopus, Web of Science e The Cochrane Library, utilizando as palavras-chaves: dor orofacial, desordem temporomandibular, bruxismo, estresse, ansiedade, biopsicossocial, diagnóstico e autocuidados, com informações importantes sobre como reduzir e controlar os sinais e sintomas de DTM e Dor Orofacial nesse momento de pandemia que estamos vivenciando um distanciamento social. Resultados: Os resultados mostram que a pandemia de COVID-19 e a necessidade de isolamento social, gera impacto psicológico que eleva o padrão de ansiedade e pode afetar diretamente pacientes com bruxismo e DTM. Conclusão: Fatores psicológicos associados à pandemia podem levar a um maior risco de desenvolver, piorar e perpetuar o bruxismo, principalmente bruxismo de vigília e DTM, por isso os cirurgiões-dentistas devem estar atentos a ocorrência de sinais e sintomas para gerenciar os aspectos multifatoriais dessa condição. Aconselha-se, nesse momento, estratégias individualizadas de autogerenciamento para o paciente que consistem em técnicas de automassagem, educação corporal, práticas de exercícios, higiene do sono e meditação. Além do uso de aplicativos digitais e ferramentas online facilitadores dessa atividade (AU)

Duration of effectiveness of Botulinum toxin type A in excessive gingival display: a systematic review and meta-analysis.

Botulinum toxin type A is effective in reducing excessive gingival display caused by hyperfunctional upper lip elevator muscles; however, this effect is transient. This study aimed to determine the duration of the effectiveness of botulinum toxin type A on a gummy smile. A systematic search was conducted using Medline (PubMed), Scopus, and Web of Science electronic databases, from 1970 to March 2017 with no language restriction; the search included studies evaluating adult patients with excessive gingival display who were treated with botulinum toxin and were followed-up for at least 3 months. OpenGrey and Clinical Trial Registry were also consulted. Quality assessment was applied to determine the level of evidence and bias, and a meta-analysis was performed. Of 2181 full texts, 71 were obtained, with 3 prospective studies meeting the selection criteria. The gingival display was significantly reduced to baseline with 2, 4, and 8 weeks of treatment. The gingival display considerably reduced at the baseline-2-week comparison (-4.44 mm using raw data and-4.05 mm using the standard difference) and increased throughout the weeks of follow-up. There is scant evidence to determine the duration of the effectiveness of toxin type A on a gummy smile. The effect tends to be stable until at least 8 weeks of follow-up, and the gingival exposure may not return to baseline within 12 weeks of follow-up. Well-designed randomized clinical trials with a minimum of 6 months of follow-up are necessary to strengthen the evidence.

The facial profile in brazilian adults

AIM: To investigate if there is agreement between measurement values obtained for Brazilian adults and the values recommended by Holdaway, Merrifield, Burstone, Steiner and Ricketts, for facial profile soft tissue analysis. METHODS: A sample of 30 cephalometric radiographs was used, consisting of 15 women and 15 men, aged 18 to 31 years, all exhibiting excellent occlusion and balanced facial profile. Comparisons were made with the measurement values proposed by the aforementioned authors using Student's t-test and to determine the correlation between the ANB and Â-H measurement values described by Holdaway, using Pearson's correlation coefficient. RESULTS: Among the measures evaluated, 4 showed statistically significant differences: Â.Z (Merrifield), S-LS and S-LI (Steiner), and E-LI (Ricketts) relative to the standards recommended by the authors. The measurement values advocated by Merrifield, Steiner and Ricketts showed statistical differences, and as for the Z-angle, Brazilians feature a slightly more convex profile, which appeared slightly concave according to Steiner, and according to the E-Plane (Ricketts), it meant an increased protrusion of the lower lip. CONCLUSION: It could be asserted that adult Brazilians have a slightly more convex facial profile than US standards, but these differences should be viewed with caution, as they are clinically unimportant (AU)
