Evaluation of individual indicators for orthodontic treatment of children with mixed and permanent dentition // Оценка на индивидуални показатели за ортодонтско лечение на деца в смесено и постоянно съзъбие

A study of individual indicators of the puberty period of growth was carried out to create a prognostic model on orthopantomogram for the initiation of orthodontic treatment. Four tasks were formulated, and 320 children aged 7–17 were examined. Evaluation of dental and skeletal age by methods applicable to routine diagnostic means in orthodontics has been performed. Digital radiographs total of 640 were analysed. The mean chronological age of the occurrence of the three stages of bone age, outlining the period of growth one year before the peak, peak and one year after the peak of puberty in Bulgarian boys and girls, has been determined. The most common stage of mineralisation of tooth germs of teeth 23, 33, 35, 37, and 38 relative to the stages of bone age during puberty was evaluated as well as their correlation. Prognostic models on orthopantomogram to determine puberty growth in girls and boys have been derived, and guidelines for the initiation of orthodontic treatment of children in mixed and permanent dentition have been indicated. The dissertation work has one contribution of an original character, six contributions of a scientific and theoretical nature and five contributions of a scientifically applied nature. The dissertation is illustrated with 39 tables, 55 figures, 5 schemes and 16 applications.
