RESUMO
OBJECTIVE: The main goal of this study is to assess the effect of adenotonsillectomy on bruxism in children with obstructive symptoms due to adenotonsillar hypertrophy. PATIENTS AND METHODS: In a prospective study, 140 children aged between 4 and 12 years with obstructive symptoms due to adenotonsillar hypertrophy were evaluated. With a questionnaire existence of bruxism was evaluated before and after adenotonsillectomy and the results were compared with each other. RESULTS: The prevalence of bruxism was 25.7% before surgery and 7.1% after it. The difference was significant by p value of 0.02. There was not any significant difference between male and female dominancy. CONCLUSION: This study suggests that adenotonsillectomy could improve bruxism significantly in children who have obstructive symptoms due to adenotonsillar hypertrophy.
