Dentoalveolar health in children with anomalies of teeth number and eruption according to orthopantomography

Abstract

We examined 80 children aged 7 -15 with the single teeth malformations. Using the OPT pictures we investigated the status of maxillary sinuses, alveolar bone tissues of upper and lower jaws, body of maxilla, ramus of mandible, and facial structures symmetry. We determined the correspondence between child’s dentition and his age, the degree of hard tissue mineralization, features of teeth development, periodontal development in accordance with the recommendations of T.E. Vinogradova (1968), F.Ya. Khoroshilkina, and T.A. Tochilina (1982). We determined teeth positions and their relationship with the neighbor teeth, compared the sizes of alveolar bone and crown mesio-distal width of unerupted teeth for predicting their eruption. Supernumerary teeth were revealed in 25 children (31.3%) with the single teeth malformations. 30 children of 80 had primary adentia (37.5 %). 23 children had teeth retention (28.8%). The possible combination of teeth malformations (2.4%) was revealed while investigating the incidence and structure of the malformations.
