Objective To evaluate the occlusal aspects of patients with and without noncarious cervical injury and identify its risk factors. Methods Through a cross-sectional study, 88 patients of both sexes between 18 and 71 years old were evaluated, in Occlusion services in the cities of João Pessoa and Campina Grande. Clinical assessments were performed by a single calibrated examiner to check the occlusal aspects of patients with and without injuries, through descriptive and non-parametric analysis with 5% significance level and 95% of confidence interval. Results Parafunctional habits were identified at a frequency of 92.0% of the patients. Unilateral chewing was not associated with the presence of lesions. The side disocclusion by the canine was prevalent in the whole sample. Occlusal interference in maximal intercuspal position and in nonworking side were presented as risk factors for the higher number of lesions and their development. Wear facets were common in the premolar groups and the maxillary arch in patients with lesions. Conclusion Occlusal factors pose risks for the development and greater number of noncarious cervical lesions.
