Quality of life of children with sleep bruxism

Aim: The aim of this study was to compare the Quality of life (QoL) of children with and without sleep bruxism in Chennai population. Materials and Methods: A cross-sectional study was conducted with participants of both genders assigned as bruxers (n = 36) and non-bruxers (n = 36) from different regions of Chennai with the age range of 6–12 years. Parents/Caregivers answered a questionnaire in the waiting room. The QoL was assessed using the Oral Health Impact Profile (OHIP-14). OHIP-14 was analyzed by Mann–Whitney U test. Results: The sociodemographic characteristics presented no significant differences between bruxers and non-bruxers (P > 0.005). There was a significant difference in QoL between the case and control group (<0.001). Bruxers had worse QoL than controls. Conclusion: Sleep bruxism may be associated with a negative impact on QoL.
