Goncharuk-Khomyn M. Clinical and experimental argumentation for children and adolescents dental treatment approaches improvement using forensic dental methods

The thesis presents a new approach for the current scientific and practically significant problem solving considering improving the efficiency and prognostic assessment of dental treatment of children and adolescents by objectifying the initial stage of development among individual teeth and the level of formation of the dental apparatus as derivatives of dental age with the use of forensic dental methods. The objective of the study was to improve the efficiency and prognostic evaluation of dental treatment among children and adolescents by objectifying the initial developmental stage of particular teeth and the formation level of the tooth-jaw apparatus, as parameters derived from the estimation of person’s dental age. The paper represents first results of the comprehensive study on the three independent dental age estimation methods (Demirjian, Haavikko, Willems) among the children and adolescents population of Transcarpathia based on a sample of University Dental Clinic patients. Based on the statistical analysis of the obtained results, a complete system of regression equations and a mathematical approach for calculating dental age among the studied sample and of each individual was proposed for the first time. Such regression equations and mathematical approach were based on the opposite direction of the errors registered during primary approbation of Haavikko and Demirjian methods. As a result of the study, the marginal values of the tooth-jaw system maturity index were established for different age subgroups for the first time. The comparison of such index values and skeletal maturity indicators makes it possible to substantiate the practical possibility and expediency of conducting appropriate orthodontic interventions in the specific time period. A differentiated approach for the apexification procedure realization was additionally justified based on the initial stage of tooth development.
