Dynamics of structure and severity of dentoalveolar anomalies on the background of early orthodontic treatment during occlusion

Background. According to the statistics, the incidence of dentoalveolar anomalies, as well as the frequency of orthodontic visits, is constantly growing. Objective. To analyze the efficiency of orthodontic treatment in children during the period of mixed dentition. Methods. We have performed a study on the incidence and severity of dentoalveolar anomalies of the dental status in 7-9-year-old patients vs. 15-17-year-old adolescents after the completion of occlusion. The adolescents were divided into two groups - those who underwent orthodontic treatment during the mixed dentition period and those who did not. The evaluation of the children’s dental status was performed using a specialized WHO Map (2013), supplemented by the «Dental Maxillofacial Anomalies» section. We determined the following indices: DMF (Decayed-Missing-Filled Index), DMF-df, OHI-S, CPI, PAR, DAI, as well as the Little’s irregularity index. The need in the different types of dental and orthodontic treatment was estimated, including that per one examined person in a group...
