INTRODUCTION AND OBJECTIVE: This study aimed to identify the presence of non-carious cervical lesions (NCLs) and correlate them to the presence of premature dental contacts and eating, parafunctional and hygiene habits involved in its development. MATERIAL AND METHODS: 100 patients were evaluated at the Federal University of Sergipe, both genders, aged 18 to 64 years, according to criteria for identifying NCLs. Individuals answered to the questionnaire with questions regarding age, gender, diet, parafunctional and hygiene habits. In the identification of cervical lesions, the vestibular and lingual or palatine faces were examined. Subsequently, the patients who presented NCLs were evaluated for the presence of a premature contact. Statistical analysis to evaluate the associations of habits with NCLs was performed using the Pearson's chi-square test. In some cases the Fisher's exact test was used. The T-Student test was used in order to compare the mean age. In all cases the significance level of 5% (p < 0.05) was considered. RESULTS: The results were statistically analyzed and no association between the presence of NCLs and the evaluated habits was found, except for unilateral mastication. CONCLUSION: The occurrence of NCLs cannot be attributed only to a single etiological factor. The highest frequency of lesions was in premolars, followed by molars, and the lowest occurrence was between incisors and canines. There is a high frequency of patients with premature contacts in the sample of patients with lesion. The increasing age of patients is directly related to the presence of lesions.
