Abstract
Background
This study evaluated the impact of bruxism on the quality of life of children and adolescents.
Methods
Electronic searches were performed in the PubMed (Medline), Scopus, Web of Science, Lilacs, Cochrane Library, and SIGLE databases. We included observational studies that evaluated general and/or oral health-related quality of life in children and adolescents, with and without bruxism. Methodological quality and risk of bias were evaluated using the Fowkes and Fulton tool. Two meta-analyses (MA) were performed. MA1 considered the mean score achieved by questionnaires, whilst MA2 considered the measure of association [odds ratio (OR)] between bruxism and quality of life.
Results
Seven studies were selected for qualitative synthesis. Three studies were selected for quantitative synthesis, which considered only oral health-related quality of life. In MA1 (three studies), the mean difference of the B-ECOHIS score was 2.12 (95% CI = −0.095–4.377, p = 0.061). MA2 (two studies) showed that bruxism is not associated with oral health-related quality of life in children and adolescents (OR = 1.889, 95% CI = 0.53–6.71, p = 0.325).
Conclusion
Bruxism does not impact quality of life in children and adolescents. Further studies should consider other quality of life questionnaires to confirm the absence of association.
