2011년 7월부터 2016년 6월까지 서울대학교 치과병원에 맹출 장애를 주소로 내원한 703명의 환자를 대상으로 897개의 치아에 대하여 맹출 장애의 빈도, 원인, 치료방법, 교정적 견인방법, 견인기간 등을 조사하여 다음과 같은 결론을 얻었다. 맹출 장애는 상악 견치, 상악 중절치, 상악 제1대구치에서 가장 높은 빈도로 발견되었다. 상악 견치의 맹출장애는 여자에게서 호발하였고(p < 0.001), 상악 중절치(p = 0.009)와 상악 제1대구치(p < 0.001), 하악 제1대구치(p = 0.028)의 맹출 장애는 남자에게서 호발하였다. 맹출 장애의 원인은 맹출 경로의 이상, 맹출 경로 상에 장애물의 존재가 가장 많았다. 치료 방법으로는 교정적 견인이 가장 많이 시행되었으며, 상악 중절치에서 가장 높은 빈도로 시행되었다. 교정적 견인 기간은 연령이 어릴수록(p < 0.001), 치관의 위치가 낮을수록(p < 0.001), 견인기간이 짧게 관찰되었다. 소아 환자는 정기적인 검진을 통해 맹출 장애를 조기에 발견하는 것이 중요하며, 정확한 진단과 치료계획으로 적절한 시기에 치료를 시작하는 것이 필요하다.
Abstract
The purpose of this study was to investigate the distribution of eruption disturbance and to analyze its causes, treatment methods, and duration of orthodontic traction, based on 703 patients with eruption disturbance who were treated in the pediatric dental clinic of Seoul National University Dental Hospital between July 2011 and June 2016. Eruption disturbance in pediatric patients was most prevalent in the maxillary canine, followed by the maxillary central incisor and maxillary first molar. Eruption disorder of the maxillary canine was more common in females (p < 0.001), whereas the maxillary central incisor (p = 0.009), maxillary first molar (p < 0.001) and mandibular first molar (p = 0.028) were more common in males than females. The most common causes of eruption disturbance were abnormality of the eruption pathway and the presence of obstacles in the pathway. Orthodontic traction was the most prevalent treatment choice for eruption disorder, mostly done for the maxillary central incisors. The duration of orthodontic traction was shorter with younger age (p < 0.001) and lower crown position (p < 0.001). It is important for pediatric patients to detect eruption disorders early through regular checkup, and it is necessary to initiate treatment at an appropriate time with an accurate diagnosis and treatment plan.
