Do Oral hygiene and Diet Favor The Development of Non-Carious Cervical Lesions? A Retrospective Study.

Purpose: The aim of this retrospective case-control study was to evaluate the influence of dental brushing factors, diet, the consumption of acidic drinks and Community Periodontal Index of Treatment Needs (CPITN) on the development of non-carious cervical lesions (NCCLs). Methods: The sample consisted of undergraduate dentistry students from different Spanish faculties (age range 18 to 29 years). NCCLs and the CPITN were diagnosed and recorded using a periodontal probe. A questionnaire was used to record different brushing factors, the consumption of extrinsic acids and the presence of intrinsic acids. The data obtained were analysed using unconditional uni- and multivariate logistic regression (significance lecel p<0.05). Results: Brushing force was a risk factor (OR=1.71). The presence of NCCLs is significantly more frequent in subjects who brush their teeth vigorously Frequent consumption of salads with vinegar or lemon increases the risk of NCCLs (OR=4.5). As the CPITN score increases, the risk of NCCLs also increases significantly (OR=1.93) for value 1 and OR=6.49 for CPITN of 3. The consumption of extrinsic acids associated with salads seasoned with vinegar or lemon, the brushing force and the CPITN were the risk factors. The model obtained has a 67.14% predictive capacity for NCCLs, a specificity of 76.43%, and a sensitivity of 57.86%. Conclusions: the results of this study show that brushing force, and acidic diet and CPITN significantly increase the risk of NCCLs. Other variables are needed to increase model prediction.
