Abstract. Background. Substantial health deterioration of primary school children over the last years allows to make a conclusion that this indicator is not only related to training load and school children lifestyle but also to delayed care seeking by parents in case of health problems in their children.

Currently the higher attention is paid to dental health in primary school children due to increasing complications as a result of malocclusion.

The purpose of the study is to substantiate and develop a set of preventive measures to prevent anomalies of occlusion in primary school children based on analysis of their health status and lifestyle.

Methods and data. During the study we examined 60 children aged 7-12 years with sagittal abnormalities of occlusion (distal and mesial), studied function of dentition prior to orthodontic treatment, after therapeutic exercises and after orthodontic treatment.

Estimation of adolescents’ health status was made by means of data extraction from school medical records (form #026-y) and from individual records of growth and development (form #112/y).

Results. Indicators of school children’ health status worsened over the period from primary to secondary school.

Results’ analysis showed that disease prevalence in primary school children during the study period increased by 68%. Such increase was identified across 16 out of 18 disease classes. Traumas, poisonings, muscular-skeletal diseases (postural abnormalities), accidents and diseases of the digestive system prevail in the morbidity structure.

The study also showed that changes in amplitude and time indexes of electromyogram of maxillofacial muscles in 7-12 year children with mesial occlusion led to distortion of coordinated muscle activity – both synergists and antagonists. This is an aggravating factor of dentofacial anomalies and requires development of preventive measures.

Conclusions. Postural abnormalities are registered in the majority of case of distal and mesial occlusion. Combination of orthodontic treatment and therapeutic exercises aimed at improving the posture accelerates recovery and provides sustainable results.

Keywords: primary school children; malocclusion; health status; lifestyle; preventive measures.
