혼합치열기 정상교합아동의 수완부골과 경추골의 성숙도 비교 연구 = THE COMPARATIVE STUDY OF CORRELATION ON HAND-WRIST WITH CERVICAL VERTEBRAE FOR SKELETAL MATURATION IN MIXED DENTITION CHILDREN WITH NORMAL OCCLUSION

국문 초록 (Abstract)

이번 연구의 목적은 소아환자의 골격성숙도 평가를 위해 경추골과 수완부골 방사선 사진의 상호연관도를 연구하는 것이다. 성적인 특징, 연령, 치아 발육, 신장, 체중과 골격성장은 성장 단계를 확인하기 위해 사용되는 일반적인 방법이다. 청소년기 전이나 청소년기 동안 성장잠재력에 대한 평가는 매우 중요하다. 본 연구는 6~18세 아동을 대상으로 측면 두부 방사선 사진과 수완부골 방사선 사진을 촬영하여 골격성숙 단계를 비교 평 가하였다. 1. 일반연령은 Skeletal Maturity Indicators(SMI)와 Cervical Vertebrae Maturation(CVM)에 비하여 적절한 골격성 숙도 표시자가 되지 못하였다. 2. SMI와 CVM의 골격성숙도는 여자의 경우 남자에 비해 더 빨랐다. 3. SMI 1, 2는 CVM 1, SMI 3, 4는 CVM 2, SMI 5, 6은 CVM 3에 해당하는 연관관계가 나타났다. 4. SMI와 CVM에 대한 측정자의 재현성 및 신뢰도는 우수하였다. 이상의 결과로 CVM도 SMI와 같이 교정치료에 있어 골격성숙도를 평가하는 적절한 방법이 될 수 있다.

The purpose of study is for the certified correlations of hand-wrist radiograph with cervical vertebrae for skeletal maturation in children. Normal evaluation devices of growth stage is sexual feature, biological age, tooth development stage, height and weight. Evaluation of growth potential is very important for childhood and puberty. The skeletal developmental stages were evaluated by using the hand-wrist radiograph and cephalometric radiograph that obtained from 6 to 18 years old children. 1. Chronologic age was not more suitable indicator of skeletal development compared to Skeletal Maturity Indicators(SMI) and Cervical Vertebrae Maturation(CVM) stages. 2. SMI and CVM stages for females occurred earlier than that for male. 3. SMI 1 and 2 stages were corresponded to CVM 1; SMI 3,4 = CVM 2; SMI 5,6 = CVM 3. 4. Reproducibility and reliability of observer for SMI and CVM were excellent. This results suggest CVM stage is comparable to SMI stage in terms of evaluating the skeletal development.
