Summary Objectives To evaluate whether the presence of non‐carious cervical lesions ( NCCL s) was related to the considered risk factors and to show the corresponding odds ratio in a predictive model. Methods The sample was 280 dentistry students. In an initial clinical examination, 140 cases were selected that presented one or more teeth with non‐carious cervical wear. For each case, a similar sex and age control without any tooth with non‐carious cervical lesions was selected. An occlusal examination and periodontal probing were performed in all cases and controls by skilled dentists. All the subjects answered a questionnaire referring to factors of brushing, bruxism, preferred chewing side, consumption of extrinsic acids and the presence of intrinsic acids. Data were analysed by means of univariate and multivariate logistic regression. Results Of all the study variables, only the protrusion interferences, interferences on the non‐working side, the brushing force, CPITN value and the consumption of salads increase the risk of NCCL s in the univariate regression. The best predictive model was formed by the combination of CPITN variables >1, the consumption of acidic salads, self‐reported bruxism, brushing force and attrition. However, it only correctly classifies 68.75% of subjects. Conclusions This study supports the multifactorial aetiology of NCCL s, the combination of several factors being necessary to explain their presence. The risk factors that make up the predictive model are not sufficient to explain the appearance of NCCL s. Dentists should take into account all these risk factors in prevention, diagnosis and treatment.
