Aim: To evaluate the effects of bruxism on oral health and quality of life between children aged 8 and 14 years. Materials and methods: This case–control study included children aged 8–14 years with bruxism (n = 30) and a control group (n = 30). A questionnaire containing questions about the child’s bruxism and systemic health was administered to the parents. The Helkimo Index and a form developed according to Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) Axis I were used to assess temporomandibular disorders (TMD), while the child perceptions questionnaire (CPQ) was employed to evaluate the impact of bruxism on oral health and quality of life and a clinical examination form was utilized to document the intraoral findings. The data were analyzed using Mann–Whitney U tests and chi-square test. A p value of < 0.05 was statistically significant. Results: The bruxism group exhibited greater overjet and overbite values, while maximum mouth opening was found to be lower. Regarding tooth wear, a significant difference was observed between the groups in permanent molar attrition. Clinical examination of the temporomandibular joint and masticatory muscles revealed statistically significant differences between the groups in terms of morning masticatory muscle pain upon waking, mandibular deviation, pain during mouth opening, and presence of linea alba. Patients with bruxism had a lower oral health-related quality of life compared to those without bruxism. Conclusion: Bruxism was associated with several oral health findings in children aged 8–14 years. It also negatively affected oral health and oral health-related quality of life.
