title: Bruxism and adenotonsillectomy.
abstract: 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.
  
  
  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.
  
  
  CONCLUSIONS
  This study suggests that adenotonsillectomy could improve bruxism significantly in children who have obstructive symptoms due to adenotonsillar hypertrophy.
