초록

본 연구의 목적은 화성시에 거주하는 유치열기 어린이의 전치부 공극과 총생에 대해 알아보는 것이다. 한 명의 소아치과 전문의가 만 3 - 4세 유치열기 어린이들의 구강 내 임상 사진을 촬영하였으며, 400명 중 237명이 포함 기준을 충족하였다. 전치부 공극의 유무는 인접면 접촉의 유무로 판단하였다. 상악에서 생리적 치간 공극이 관찰되는 어린이는 47.3%였으며, 하악에서는 38.0%였다. 양악 모두에서 접촉 혹은 총생의 치열을 보이는 어린이는 43.5%였다. 여아보다 남아에서 생리적 치간공극이 존재하는 경우가 더 많았다. 상악에서는 영장류 공간이 발육공간에 비해 더 많이 발견되었으나, 하악에서는 그 차이가 적었다. 상악에서는 유중절치 사이에 공극이 있는 경우보다 유중절치와 유측절치 사이에 공극이 있는 어린이가 더 많았으며, 반면 하악에서는 유중절치 사이에 공극이 있는 어린이가 유중절치와 유측절치 사이 혹은 유측절치와 유견치 사이에 공극이 있는 어린이보다 많았다. 본 연구를 통해 3 - 4세 유치열기 어린이의 전치부 공극과 총생의 정도를 파악할 수 있었으며, 추후 더 많은 표본으로 조사가 필요할 것으로 사료된다. 유치열기의 전치부 공극 혹은 총생은 어린이 개인에 따라, 성별에 따라, 악궁에 따라, 치간 위치에 따라 다른 정도를 보이므로, 치과의사는 유치의 치관부를 수복할 때 이에 대한 인식 하에 치료를 시행하여야 한다.

The aim of this study was to assess the spacing and crowding of the anterior teeth in the primary dentition in Hwaseong city. Photographs of the anterior segment of 237 children satisfied the criteria. The presence of primate spaces and developmental spaces was assessed by the proximal contacts. Physiologic spacing was observed in 47.3% and 38.0% of the cases in the upper and lower arches, respectively. 43.5% showed the presence of two-segment contact or crowded dentition. Physiologic spacing was observed more in boys than in girls. In the maxilla, primate space was more frequent than developmental space; however, in the mandible, the difference was low. In the maxilla, the space between the central incisor and the lateral incisor was more frequent than the space between both central incisors. In contrast, in the mandible, the space between both central incisors was more common than the space between the central and lateral incisors or between the lateral incisors and canine. The present study describes the tendency for anterior spacing and crowding in the primary dentition. Further longitudinal studies with a larger sample are needed. Dentists should consider these concepts of spacing or contact/crowding when performing full coronal restorations of primary anterior teeth.
