Treatment of bruxism in children: a systematic review.

Objective: To conduct a systematic review to assess and analyze the scientific evidence about the available therapies for bruxism in children. Method and Materials: The literature was searched using Medline, PubMed, Ovid, Biomed Central, EBSCOhost, ISI, Cochrane Library, Embase, LILACS, Scielo, Scirus, the Internet at large, and databases of universities from March 1985 to the end of September 2007. Studies had to be intervention studies for bruxism in children, and the children included in the studies had to be 3 to 10 years old. Results: From 52 records found, 2 fulfilled the inclusion criteria. In 1 study, bruxism was treated by widening the upper airway through adenoidectomy, and the other study proposed to treat bruxism in children with psychologic techniques. When analyzed, the 2 considered studies did not fully accomplish the requirements to treat the etiology of bruxism in children. Conclusion: The available literature does not provide adequate support to treat bruxism in children, as the diagnosis methods in the studies are insufficient and are not comparable to confirm the presence of bruxism. Very few studies about therapies for bruxism in children meet the quality criteria required for the evidence-based practice. Treatment for bruxism in children requires further study.
