Is there an association between bruxism and intestinal parasitic infestation in children?
PURPOSE: Multiple factors have been considered in the etiology of bruxism in pediatric patients, among which are infestations by intestinal parasites suggested by some authors. No empirical evidence exists, however, of such association. Therefore, this study’s purpose was to investigate the existence of an association between bruxism and intestinal parasitic infestation in children. METHODS: Fifty-seven 6- to 11-year-olds (30 cases and 27 controls) who had not used anthelminthics 2 months before the baseline examination were enrolled in the study. A diagnosis of bruxism was based on an intraoral clinical examination performed by a single trained examiner and on the parent/guardian’s report of any perceived parafunctional habits (questionnaire-based interview).
