Objetivo: Determinar os níveis de ansiedade dos indivíduos com bruxismo e avaliar a existência de disfunção temporomandibular nesses indivíduos.
Materiais e Métodos: Foram incluídos no estudo 35 indivíduos que realizavam tratamentos na Faculdade de Medicina Dentária da Universidade de Lisboa e que foram diagnosticados com bruxismo. Esse diagnóstico foi realizado por meio dos critérios propostos pela Academia Americana de Medicina do Sono em 2001 (Bruxismo do Sono) ou de uma resposta positiva à questão “Já se apercebeu se range ou aperta os dentes durante o dia” (Bruxismo da Vigília). Após confirmação do diagnóstico, os dados foram recolhidos por meio de observação clínica e do preenchimento de um questionário para quantificar a ansiedade. A observação clínica teve por base os critérios de pesquisa para as disfunções temporomandibulares, e para a quantificação da ansiedade foi utilizado o Inventário de Ansiedade de Beck.
Resultados: A amostra estudada era maioritariamente do género feminino (82,9%) e apresentava uma média de idades de 44,0 ± 20,27. Dos 35 participantes, 16 (45,7%) foram diagnosticados com ambas as formas de bruxismo, e 16 (45,7%) foram diagnosticados com algum tipo de DTM. Grande parte dos participantes (40,0%) apresentava grau mínimo de ansiedade. Verificaram-se valores médios de ansiedade mais elevados nos participantes que apresentavam bruxismo misto e nos participantes com DTM. No entanto, não foram encontradas diferenças estatisticamente significativas no que diz respeito às relações entre tipo de bruxismo, grau de ansiedade e presença de DTM (p>0,05).
Conclusões: Apesar da ausência de significância estatística nas análises do presente estudo, não devem ser desconsideradas potenciais associações, pois em estudos com uma amostra maior esta relação pode ser expressa estatisticamente.
Purpose: To measure the levels of anxiety of individuals with bruxism and evaluate the existence of temporomandibular disorders in these individuals. Materials and Methods: 35 individuals who underwent treatments in Faculdade de Medicina Dentária da Universidade de Lisboa and had a positive diagnosis of bruxism were included in the study. That diagnosis was made according to the criteria proposed by American Academy of Sleep Medicine in 2001 (Sleep Bruxism) or by a positive answer to the question “During the day, do you grind your teeth or clench your jaw?” (Awake Bruxism). After the diagnosis of bruxism, data was gathered by clinical observation and a questionnaire to quantify anxiety. Clinical observation was based on the Research Diagnostic Criteria for Temporomandibular Disorders, and anxiety was measured through the questionnaire Beck Anxiety Inventory. Results: The sample was mainly feminine (82,9%) and the mean age was 44,0 ± 20,27. Of the 35 participants, 16 (45,7%) were diagnosed with both forms of bruxism, and 16 (45,7%) were diagnosed with TMD. A large part of the participants (40,0%) exhibited minimum degree of anxiety. Higher mean values of anxiety were observed in participants who had mixed bruxism and in participants who had TMD. However, no statistical significant differences were observed regarding associations between type of bruxism, level of anxiety and existence of TMD (p>0,05). Conclusion: Although results were not statistically significant, potential associations must not be rejected, since studies with large samples may exhibit a significant relation between variables.
