Objective: To evaluate the relationship between canine guided and group function occlusion schemes and tooth wear along with salivary factors such as salivary flow rate and salivary pH. Methodology: A cross sectional descriptive study was conducted among 50 subjects, 25 of group function and 25 of canine guided occlusion. Type of occlusion pattern and tooth wear was assessed through clinical intra-oral examination. Lateral excursive occlusion was determined with the aid of Shimstock to confirm tooth contact and the modified ordinal scale was used for evaluating tooth wear. Working side occlusal contact patterns were determined and classified into two groups: canine guided and group function. Unstimulated and stimulated whole saliva sample was collected to assess the pH and salivary flow rate. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 21, IBM Inc. Descriptive data was reported for each variable. As the data was found to be normally distributed bivariate analyses was performed using Independent t test. Level of statistical significance was set at p-value less than 0.05 Results: No significant difference was seen in pH when compared between canine guided and Group function occlusion as p >0.05 whereas flow rate was found to be significantly more in group function. Conclusion: Most of tooth wear in canine guidance is reported in mandibular incisor followed by mandibular molar. No wear was seen in both maxillary and mandibular canines and minimal wear was reported in maxillary incisor. Type of occlusion did not affect the salivary pH rather it affected salivary flow rate.
