Introduction: Non-carious cervical lesions affect the tooth cervix and their progress can affect the pulp organ. Objective: To determine the prevalence of non-carious cervical lesions. Methods: An observational, descriptive and cross-sectional study was carried out. The sample consisted of 750 patients between 18 and 70 years of age. The prevalence of non-carious cervical lesions was evaluated according to sex, age and frequency according to dental group (incisors, canines, premolars and molars). The chi-square test was used to evaluate the association according to sex and age group. Results: The prevalence of non-carious cervical lesions in the patients attended was 68.0%. In relation to sex, the prevalence was higher in females with 44.4% (p< 0.05). The age group with the highest prevalence was 46 to 70 years old with 33.8% (p< 0.01). Abrasion occurred in the incisors with 17.1%, erosion and abfraction in the premolar group with 10.4% and 13.5% respectively. Conclusions: The prevalence of non-carious cervical lesions was more than half of the patients evaluated, with a higher prevalence in women and in adults between 46 and 70 years of age; abrasion was the most frequent cervical lesion, especially in the incisor group.
