Abstract

Considering the reported prevalence and risk factors of non-carious cervical lesions (NCCLs), the present study aims to evaluate the prevalence and the factors associated with NCCLs in a Colombian higher-level institution. Materials and Methods: An observational, analytical, cross-sectional study was done, the sample consisted of 105 patients, over 40 years of age, of both sexes. A survey was carried out with sociodemographic characteristics and factors associated with NCCL, followed by a clinical examination to record NCCLs, type of lesions and occlusal factors such as: malocclusions, coincidence of midlines and dental crowding. The statistical analysis included continuous variables, accompanied by measures of central tendency and categorical variables with absolute and relative frequencies in percentage, a multimethod regression analysis was done. Results: NCCLs were diagnosed in 53.3% of the total respondents, with abfraction being the most prevalent type of lesion found in 39.1% of the participants. NCCL were significantly associated with tooth brushing habits, frequency of consumption of carbonated beverages and citrus fruits, and parafunctional habits. Statistical significance was found in the diagnosis of tooth sensitivity, malocclusion, bruxism, xerostomia, use of removable prosthesis, open bite, crossbite, midline coincidence and crowding. In the Multiple regression analysis, the Aggressive technique of brushing whit an OR of 9.9 (P<0.05) and tooth sensitivity OR 3.4 (P<0.05) were related whit NCCLs Conclusions: This study showed a relatively high frequency of NCCL in subjects in the age range of 40 to 80 years.
