Regional features dentition in preschool and primary school age in Vladivostok

Abstract

The eruption of permanent teeth is one of the main indicators of the normal dentition forming system of children, and also recognized the main criterion for determining the level of biological development of children ofpreschool and early school age. The aim of the work was to study the characteristics of dentition in children of Vladivostok. There was studied the process of eruption of permanent teeth in children 2239 4,5-11 years with I-II health group and residing in Vladivostok. The beginning of eruption is the moment of perforation tooth alveolar gums exposing a tuber or cutting edge. Revealed the frequency of dentition in the child population, which is calculated based on the average age ranges dentition in boys and girls ofpreschool and early school age. Determine the average total number ofpermanent teeth in children of both sexes. It was found that the first permanent teeth begin to erupt in 4,5 years. Throughout the period of the eruption of the girls noted earlier appearance ofpermanent teeth, compared with boys. Girls characteristic right-teething, or boys - left hand. The children of both sexes in the mandibular incisor is marked type of eruption, the maxilla - molar. The first children in the mandibular central incisors appear on the upper jaw - the first molars. The differences in the sequence of teething for the upper and lower jaw. Designed by regional standards dentition may be used in determining the biological age of children is at the individual level as well as in conducting monitoring studies.
