Regular Physical Activity as a Potential Risk Factor for Erosive Lesions in Adolescents

Tooth erosion is becoming an increasingly common dental problem among teenagers. The study aimed to determine risk factors for erosive lesions in young sports professionals. Participants were 155 students—102 physically active and 53 controls. The method included dental examination (including Basic Erosive Wear Examination) and a questionnaire concerning sports activity, dietary and hygienic habits. The sporting activity significantly correlated with erosive lesions (R_Spearman = 0.344). The regression model incorporating the kind of sports activity, special diet and (non-)drinking water was statistically significant (p = 0.922 for the Hosmer–Lemeshow test) and strong enough to predict erosive lesions in young athletes (AUC = 0.758). Water sports professionals were almost 14 times more likely to suffer from erosive lesions than control students. Drinking water as the main beverage decreased the odds by about 70%. The graphical interpretation of multidimensional correspondence analysis confirms the predictive value of these factors. The kind of sports activity adjusted by the main beverage and a special diet was the best variable to predict erosive lesions among teenagers. Early proper diagnosis with defined risk factors leads to better prevention and successful treatment.
