Objective: The purpose of the study is to verify the presence of a correlation between the type of malocclusion and a specific type of tooth wear in young patients. Material and method: 37 students of the Faculty of Dental Medicine at the Bucharest “Carol Davila” University of Medicine and Pharmacy were selected according to standardized criteria. The study group was divided in 3 smaller groups: group 1 - with neutral occlusion, group 2 - class II/1 Angle anomaly, and group 3 - class II/2 Angle anomaly. Once the study models were made, the assessment of the loss of dental tissue was carried out by two calibrated examiners, by using a modified tooth wear index TWI, per tooth and at the level of each dental surface. The information gathered from the subjects was centralised in a database and statistically interpreted with the PASW 18 statistic software; the test applied was the Mann-Whitney U-test. Results: At each of the three groups studied, the surfaces on which the wear had the greatest impact were the occlusal surfaces / incisal margins; they displayed mostly early lesions, in neighbouring ratios (17.87% for neutral occlusion, 15.63% for class II/1 Angle, and 20.03% for class II/2 Angle), the distribution of the loss of hard dental tissue at the level of the other surfaces being different. The influence of gender on the relationship wear-anomaly could only be established for class II/2, with differences significantly in favour of the male gender for teeth 1.7 and 2.7, respectively in favour of the female gender for 3.5. Conclusions: our study points to the presence of tooth wear both in subjects with neutral occlusion and in subjects who have a class II Angle anomaly, with differences of the wear patterns, which does not allow, however, to establish a statistically significant influence between the two variables.
