RESUMO
The objective of this study was to determine tooth wear in canine guidance and group function occlusion in both genders. A cross sectional descriptive study with sample size of 84 having 42 in each gender was conducted at OPD of Sardar Begum Dental College Peshawar from February 2013 to March 2014. Patients of both genders having all permanent teeth present except third molar were included in the study. Patient's age, gender and occlusion type [canine guidance or group function] were recorded. All posterior teeth wear were graded according to Eccles and Jenkins index. Mean age of patients was 23.9 +/- 3.27 years. Twenty seven [32.1%] patients were reported with no wear and 57[67.9%] were observed with tooth wear. Patients having canine guidance occlusion were 53[63.1%] and group function were observed in 31[36.9%]. Tooth wear in group function was reported in 53% and 15% in canine guidance. Canine guided occlusion was common in both males and females as compared to group function. This study revealed that group function occlusion is more prone to tooth wear and the observed population has more frequency of canine guidance occlusion
