Prevalence and Structure of the Malocclusions in Children from Boarding Schools
Journal Title: Lviv Clinical Bulletin - Year 2015, Vol 2, Issue 10
Abstract
Introduction. Publications of the last years demonstrate the growth of malocclusions prevalence along with other main stomatological diseases. The researches carried out in different regions of Ukraine revealed some regional and age peculiarities of malocclusions prevalence. Formation of the orthodontic pathology has polyetiological genesis and is the result of endogenous and exogenous factors. Among the risk factors that influence their formation the most important are the biological, environmental, hereditary, natural, geochemical and especially social – domestic, because the standard of living and nutrition, living conditions, even family atmospheres ignificantly influence the state of health, including dental health. Orthodontic pathology which is not detected and not cured at the stage of the temporary and mixed dentition, becomes more expressed and severe in permanent dentition. That’s why their early detection is very important in children at the stage of temporary dentition, when dentoalveolar system is under constant growth. The elimination of risk factors in time of the initial manifestation of the disease can provide the normalization of development, and the study and analysis of prevalence malocclusions among children of different groups becomes the basis for forecast and prevention of severe forms of malocclusions. Particular interest in this aspect is the study of the basic indices of the prevalence and structure of malocclusions in children who live and study in the boarding schools, taking into consideration the fact that these children drop out of sight of doctors-orthodontists. Purpose of the research – assessment of the prevalence and structure of orthodontic pathology in children from boarding schools. Materials and research methods. An epidemiological survey of 528 children from boarding schools of Lviv and Lviv region (main group) and 122 secondary school children (control group) at the age of 7, 9, 12 and 15 years. The results were recorded in a specially worked out cards. Classification of D. Kalvelis was used to verify the diagnosis of malocclusion. The results of the research were statistically processed using the Student’s test. Results of the investigation and their discussion. The results of the investigation showed that the prevalence of malocclusions in children from the main group is 84.09 ± 1.54 %, and in children from the control group – 66.39 ± 4.28 %. Analysis of the received results showed that with the age the number of children with maloccluisons increased. So, the malocclusions prevalence in children from the main group increases up from 80.45 ± 3.44 % in 7-year-old children to 87.90 ± 2.93 % in 15-year-old children. However, malocclusions prevalence in children from the control group increases from 61.29 ± 8.75 % (in 7-year-old children) to 76.67 ± 7.72 % in 12-year-old children (it’s the peak of prevalence). Further up to 15 years is noticed the decrease of malocclusion prevalence in children (to 58.62 ± 9.15 %). Anomalies of the dental arches were diagnosed in 77.08 ± 1.83 %, anomalies of individual teeth – in 16.67 ± 1.62 %, anomalies of occlusion – in 41.86 ± 2.15 %. No child with maloccluions from boarding schools, was under orthodontic treatment. The analysis of the malocclusions structure of surveyed children according to the age showed that the incidence of abnormalities of the dental arches was at a high level, ranging from 70.68 ± 3.95 % to 80.65 ± 3.55 %. Otherwise, was fixed the growing of prevalence of anomalies of occlusion at the age from 7 to 15 years from 33.08 ± 4.08 % to 49.19 ± 4.49 %, because of the lack of self-regulation processes and the lack of orthodontic treatment. However, up to 12 and 15 years we have seen the growing of prevalence of anomalies of the individual teeth to 16.67 ± 3.17 % and 23.39 ± 3.80 % respectively. However, already at the age of 12 years, when the self-regulation should take place, the prevalence of all forms of malocclusions is increased, and in the age of 15 years the prevalence of anomalies of individual teeth in children from boarding-schools reached 23.39 ± 3.80 %, prevalence of dental arches – 80.65 ± 3.55 % and anomalies of occlusion – 49.19 ± 4.49 %. Conclusions. In our opinion the increase of malocclusion frequency in children of the main group with age is due to the absence of orthodontic treatment, as well as to the absence of self-regulation processes. The obtained results underline the necessity of the further researches on the subject of the main features of the main stomatological diseases in children with malocclusions, who study and live at boarding schools.
