Abstract

This study aimed to evaluate the masticatory performance of Korean children and adolescents and to investigate related factors. Early loss of primary molars, degree of occlusion of first molars, occlusal relationship of first molars, and presence of anterior crossbite were considered. From March 2020 to July 2021, 56 children and adolescents between the ages of 6 and 12 were included. The mixing ability index (MAI) was calculated to evaluate the masticatory efficiency of children and adolescents. The subjects were classified into three groups according to the number of early lost primary molars; normal dentition, 1 - 2 teeth lost, more than 3 teeth lost. The number of participants are 23, 18, and 15, respectively. There was no difference in the MAI values between the normal dentition group and the group has 1 - 2 teeth lost. However, when 3 or more primary molars were lost, the MAI value decreased and a significant difference was observed. This study is the first study to evaluate the masticatory performance of children and adolescents in Korea, and it will be helpful to pediatric dentists who evaluate the masticatory performance of children and adolescents and strive to improve the masticatory efficiency of children and adolescents in clinical practice.

이 연구는 국내 소아청소년의 저작 능력을 평가하고 관련 요인들을 조사하고자 하였다. 유구치의 조기 상실, 제1대구치의 교합 정도, 제1대구치의 교합 관계, 전치부 반대교합의 유무를 고려하였다. 2020년 3월부터 2021년 7월까지 56명의 만 6세에서 12세 사이 소아청소년을 대상으로 하였다. 혼합능력지수(MAI)가 소아청소년의 저작 능력을 평가하기 위해 계산되었고 유구치의 조기 상실 개수에 따라 세 집단으로 분류한 연구대상자는 정상 치열, 유구치 1 - 2개 상실, 유구치 3개 이상 상실한 경우 각각 23명, 18명, 15명이었다. 정상치열군과 1 - 2개 유구치 상실군에서는 MAI 값에서 차이가 없었으나, 3개 이상 유구치를 상실한 경우 MAI 값이 감소했으며, 유의한 차이가 관찰되었다. 이 연구는 국내 소아청소년의 저작 능력을 평가한 최초의 연구로, 성인과 저작 능력을 비교하였으며, 임상에서 소아청소년의 저작 능력 증진을 위해 노력하는 소아치과 의사에게 도움이 될 수 있다.
