Abstract: 

Background & Aim: The present study aimed to investigate the relationship between dental noncarious cervical lesions and parafunctional habits such as Bruxism and Clenching. Besides, the relationship between dental premature contact in Eccentric and Centric movements, and noncarious cervical lesions of teeth was studied.
Method & Material: The study done descriptively. Two groups of patients were obtained from population visited in the faculty of Dentistry, Mashhad, IRAN. The first group containing 40 patients had Bruxism and Clenching habits, and the second group, containing 37 patients, had no history of these habits, considered as control. Patients in both groups were screened for the wedge-shaped noncarious cervical defects. If present, the teeth were examined for dental premature contacts in Eccentric and Centric movements.
Results: The incidence of wedge-shaped noncarious cervical lesions was significantly higher (70%) in the group of patients with Bruxism and/or Clenching habits than the control group. The results revealed that in both groups the frequency of occurrence of dental premature contacts at side was positively correlated with that of noncarious cervical lesions. There were no significant differences in the frequency of occurrence of these lesions between the patients with Bruxism and Clenching habits.
Conclusions: The parafunctional habits are very important with regards to the loss of dental tissues and the occurrence of cervical lesions, particularly if prematural contacts present.
