Abstract
Purpose: The purpose of this study was to determine the frequency of the upper incisors crown trauma and its relationship to orthodontic anomalies, as well as the influence of age, gender and occlusal characteristics. Material and Methods: In this study 580 subjects (302 boys and 278 girls) between 7 and 15 years were randomly selected from several primary schools in the Republic of Croatia. Following characteristics were examined: frequency of incisor trauma, gender, age, skeletal relationship, incisor exposure, interlabial distance, overjet and maximum vertical opening of the mandible. Results: crown trauma was found in the total of 12.4% frequency. It was more frequent in boys (17.8%) than in girls (6.5%). The most frequent type of trauma was a non-complicated trauma affecting only the enamel (80%). Conclusions: The trauma frequency was not related to the size of the maximum vertical opening of the mandible, to the type of malocclusion and the overjet. Subjects with greater size of interlabial distance and incisors exposure had shown more risk to upper incisor trauma.
