Prevalence of Tooth Wear with Canine Guided and Group Function Occlusion in Rehman College of Dentistry

Abstract

Objective: To determine the prevalence and extcnt of tooth wear in canine guided and group function occlusion.

Methodology: This Cross sectional study was performed at the Department of Prosthodontic, Rehman College of Dentistry, Peshawar involving 383 patients aged 18 to 30 years visiting the OPD for restorative treatment. The occlusal scheme for each patient was determined, canine guidance was defined by disocclusion of posterior teeth on the working side, while group function involved multiple simultaneous contacts. Tooth wear was assessed using the Bardsley classification system in the occlusion groups. Data were analysed with SPSS 24.

Results: Mean age of the cohort was 23.86 ± 3.74 years, with 210 (54.8%) male and 173 (45.2%) female patients. Canine guided occlusion was observed in 237 participants (61.9%), group function occlusion in 146 (38.1%) patients. Severe tooth wear (Grade 2) was significantly more common in the group function group (28, 19.2%) than in the canine guidance group (18, 7.6%) (P = 0.001).

Conclusion: Prevalence and severity of tooth wear was significantly higher in the group function occlusion compared to canine guided occlusion.
