The time of eruption of permanent teeth in children between the ages of 7 and 8

Subject. The issues of indications, contraindications and the optimal timing for the removal of abnormally located lower third molars remain relevant in dentistry. Numerous evidence has been accumulated of their negative impact on the formation of the dentofacial system, however, X-ray patterns of patients with this pathology in the process of their formation, development and change in the angle of inclination, as well as the growing problems associated with the growth of these teeth in the dentition and bite have not been studied. The goal is to study the dynamics of the position of the rudiments of the abnormally located lower third molars in the process of their formation and growth and their influence on the state of the dentofacial system as a whole. Methodology. The study involved 28 patients with abnormally located impressive lower third molars, which were divided into 3 groups: in the first (8 people), the second molars were at the teething and growth stage, in the second (12 people) the second molar was in the occlusal plane at the stage closed apex, in the third (8 people) there was a multiple abnormal position of the mesially located teeth from the third molar. All measurements were performed using a virtual measuring device in the image mode of slices with Galileos Viewer software. Results. According to our results, a significant scatter was recorded in the timing of the formation of third molars from the period of mineralization of the crown of the teeth (12―15 years) to the end of growth and root formation (18―23 years). After 23 years, the roots of the abnormally located lower third molars in the patients examined by us had radiological signs of the end of formation (closed apex). Conclusion. Impact lower third molars continue their growth and have a negative effect on the condition of the teeth located mesial. This fact does not depend on concomitant orthodontic pathology, nor on the methods of orthodontic treatment (removable or non-removable equipment).

Subject. The research of influence risk factors is conducted on secondary dentition of the children's population of the region. The share contribution is established habitat factors in an indicator of a tooth maturity of children. Purpose — studying influences of risk factors on secondary dentition of children in Vladivostok. Methodology. Dental maturity was assessed by the eruption time of permanent teeth and their number. Factors of pregnancy and childbirth, early childhood, medical and biological factors, social and hygienic factors characterizing living conditions, as well as hygienic-regulated factors of lifestyle by means of questionnaires of parents (guardians) of children have been studied. The hygienic assessment of the actual food was carried out by means of determination of average amount of the studied food ingredients of diets of children preschool age according to the menu apportions and specially developed questionnaires, children younger school age – by questioning of parents (trustees) of children. Results. It was revealed that the central incisors were the first in children of both sexes on the lower jaw, and the first molars on the upper jaw. Girls had earlier eruption through permanent teeth. Potential risk factors of disturbance of eruption are established second teeth of children of preschool and younger school age. Are revealed imbalance of food of children, non-performance of the recommended volume physical activity and duration of walks, discrepancy of duration day dream to hygienic recommendations and continuous work on the computer, tablet, notebook. Dependences between studied potential are defined risk factors and tooth maturity of children. Identification causal is carried out investigative bonds in the system of factors of the habitat and eruption of constants teeth of children. It is established that the maximum influence on an indicator of a tooth maturity render: nutrient structure of food allowances of the child, food of women in time pregnancies, the hygienic normalized factors of a way of life of children. Conclusions. Share contribution of each of factors to forming of a tooth maturity of a children's organism allowed to prove and develop a complex of actions for prevention scientifically disturbances of health among the children's population of the region.
