Aim: The aim of this study is to investigate the relationship between side occlusion with temporomandibular joint problems (TMD) and parafunctional habits among Dentistry Students of Tabriz University of Medical Sciences. Materials and Methods: In this cross - sectional study, 98 students from the School of Dentistry of Tabriz University of Medical Sciences were randomly selected, and the occlusion was also examined. Data from the study were analyzed using descriptive statistics and chi-square test software SPSS 17. Results: In this study, 16.33 % of population had Group function occlusion, 13.23 % had Anterior Group function occlusion and 70.4 % had canine raise occlusion. 3.1% of people had functional Paralympic symptoms of Bruxism and 6.1 % were marked with Parafunctional clenching. The study population consisted, all patients with Group function occlusion that had para-functional habits. However, in patients with canine raised occlusion, 63.3 % para-functional habit parameters, 2 % has Bruxism and 1.5 % had clenching. Conclusions: a significant relationship was not observed between side occlusion with parafunctional habits and TMD problems among students of Tabriz University of Medical Sciences.
