Taking into account the presence of pre-conducted epidemiological studies on the territory of Transcarpathian region devoted to the question of major dental pathologies prevalence among children, it is advisable to systematize and compare their results with each other, as well as with data obtained during a specifically formed study sample of children and adolescents.
The aim of the study – to provide a comparative analysis of the major dental pathologies prevalence among children of Transcarpathian region according to the data of the studied clinical sample and preliminary performed dental populational studies.
Materials and Methods. For the realization of the formulated research objective, a retrospective analysis of medical records and a dental examination of 411 children and adolescents were provided on the base of University Dental Clinic (Uzhhorod National University). Categorization of patients was provided due to their age-related passport indices with the formation and distribution of subgroups with a 1-year difference. Google Scholar search form (http://scholar.google.com) was used with its advanced features for the systematization of previously conducted studies aimed at registration of major dental pathologies among children of Transcarpathian region. The following sets of words «dental disease», «children» and «Transcarpathian region» were used as header operators in various combinations, each resulting for the set of academic papers on relevant topics, that were subsequently subject to content analysis.
Results and Discussion. The average caries prevalence among studied clinical sample of 411 pediatric patients in the age range of 6.0–15.9 years was 73.2 % (included in the range of results provided by pre-conducted epidemiological studies), the average teeth crowding prevalence in the age range of 6.0–15.9 years was 18.82 % (below the range of results provided by pre-conducted epidemiological studies), the average dystopia prevalence in the age range of 6.0–15.9 years was 14.69 % (included in the range of results provided by pre-conducted epidemiological studies), the average primary edentulism prevalence in the age range of 6.0–15.9 years was 2.31 % (included in the range of results provided by pre-conducted epidemiological studies), the average super numerary teeth prevalence in the age range of 6.0–15.9 years was 0.82 % (included in the range of results provided by pre-conducted epidemiological studies), the average delay in teeth eruption prevalence in the age range of 6–15.9 years was noted in 8.65 % of clinical cases (included in the range of results provided by pre-conducted epidemiological studies).
Conclusions. Thus, in the course of this phase of study, which was aimed to provide comparative analysis of the major dental pathologies prevalence among children and adolescents, and was conducted through a retrospective review of medical documentation and examination of 411 dental pediatric patients, it was found that the established prevalence of different pathologies does not statistically differ from the indicators, which were given in previous epidemiological studies. The small absolute difference of the indicators can be justified by the discrepancy in the size of samples being studied, the analysis of the certain pathologies prevalence outside Transcarpathian regions, the discrepancy in age categorization given in various studies, the researches of the stomatological status of the children's population living in different regions of Transcarpathia.
