Abstract

Delayed eruption of the first molar, without a generalized or localized cause, is usually associated with delayed development of the affected tooth. The aim of this study was to investigate the clinical features of the first permanent molar showing delayed development and eruption, and its association with developmental anomalies of other teeth. Panoramic radiographs of 40 healthy children showing delayed development and eruption of first permanent molars were analyzed. The clinical features of affected first molars and developmental anomalies of other teeth (except third molars) were evaluated. Delayed first molars were more frequent in the maxilla. The incidence of bilateral delayed development of first molars was greater than that of unilateral cases in female patients. In contrast, male patients showed unilateral delayed development of the first molar more frequently. A higher incidence of congenitally missing teeth was observed in patients with delayed first molar. In each case, delayed development or congenital absence was observed in the second molar adjacent to the delayed first molar. Overall, delayed first molar seems to be associated with congenital absence of additional teeth. Understanding the developmental mechanisms of this phenomenon requires further studies.

국소적, 전신적 요인을 동반하지 않는 제1대구치의 맹출 지연은 해당 치아의 발육 지연을 동반한다. 본 연구의 목적은 제1대구치의 발육지연의 임상적 양상 및 동반하는 다른 치아의 발달 이상에 관하여 고찰하는 것이다. 국소적 요인이 없이 제1대구치 맹출 지연을 보이는 건강한 어린이 40명의 파노라마방사선 사진 분석을 시행하였다. 2명의 평가자가 Nolla 방법을 이용하여 해당 치아의 발육지연 여부, 해당 분악의 제2대구치 발육 이상 여부 및 제3대구치를 제외한 다른 치아의 선천적 결손 여부에 관하여 조사하였다. 제1대구치의 발육지연은 상악에서 호발하였고, 여성에게서 양측성 이환, 남성에게서 편측성 이환이 많이 관찰되었다. 제1대구치의 발육지연이 있는 환아는 유의하게 높은 선천적 결손치의 유병률을 보였으며, 이환된 분악의 제2대구치는 모두 발육 지연 혹은 선천적 결손의 이상을 보였다. 본 연구결과 제1대구치의 발육지연은 다른 치아의 선천적 결손과 밀접한 연관이 있는 것으로 나타났다.
