초록
선천성 치아 결손(congenital missing teeth)은 1개 이상 치아의 선천적 결손으로 hypodontia라고도 불리며 인간에서 가장 흔한 치아 발육 이상이다. 그러나 6개 이상 영구치가 결손되는 severe hypodontia, 또는 oligodontia의 경우는 0.3-0.4%의 매우 낮은 유병율을 보인다. 이환치는 제3 대구치, 상악 측절치, 하악 제2 소구치 순으로 빈발한다. 원인은 정확하게 알려진 바는 없고 외배엽 이형성증, 다운 증후군과 같은 전신질환이나 특정 유전자의 돌연변이와 연관되어 나타나기도 한다. 선천성 치아 결손이 존재하면 비이환치의 위치 이상이나, 악골 발육 감소, 심미적, 기능적 문제 등이 발생할 수 있다. 조기 발견을 통한 해당 유치의 보존이 중요하며 이러한 상황의 개선을 위해 한 사분악 당 최소의 저작 단위를 확보할 수 있도록 교정적, 보철적으로 포괄적인 치료가 필요하다. 본 증례는 전신질환이 없는 다수의 영구치 선천 결손 환아에 대한 보고로써 이들은 교정치료와 간격유지를 위해 주기적으로 내원하고 있다.
Abstract
Congenital Missing Teeth(hypodontia, oligodontia) is the developmental absence of one or more teeth. It has been reported as being the most common anomaly of dental development in human, relatively common in the permanent dentition. In a recent review, Vastardis has quoted incidence ranges of 1.6%-9.6% in the permanent dentition. Brook has quoted a prevalence of 3.5-6.5% in most populations, with severe hypodontia, defined as the absence of six or more teeth, having a prevalence of 0.3-0.4%. The most commonly affected teeth are third molars, followed by maxillary lateral incisor, and second premolars. The etiology is unknown, several hypotheses include trauma, nutritional deficiency, infection, metabolic abnormalities, systemic disease and genetic influence. The multiple congenital missing is commonly associated with specific syndrome or severe systemic abnormalities such as cleft lip & palate and Down's syndrome. These cases present that children have multiple congenital missing teeth in the permanent dentition, without any systemic disease. Management of this condition must be considered orthodontic and prosthodontic treatment comprehensively. In these cases, children were treated by space maintainer or orthodontic appliance and follow-up checked.
