Abstract

Congenital absence of the primary canines is very rare. Congenital absence of primary teeth often causes their successors to not develop at all or affects the eruption of their successors. The purpose of this paper was to report the cases of 2 children with early eruption of the maxillary permanent canines at ages 4 and 6 years, respectively, following congenital absence of their maxillary primary canines, which are not common in earlier studies. Although tooth eruption and shedding exhibit some physiological variation, certain clinical cases are extreme. Premature eruption of the maxillary permanent canines may cause complications in terms of the space available for the eruption of adjacent teeth. Additionally, early eruption of permanent teeth increases the need for more careful oral hygiene. Therefore, the pediatric dentist must be alert to such rare cases.

유치의 선천적 결손은 흔하지 않으며, 특히 유견치의 선천적 결손은 드물다. 일반적으로 선천적 결손에 따른 후속 영구치에 미치는 영향으로 후속 영구치 또한 선천적 결손 되거나, 발육 시기에 영향을 주는 경우가 보고되어졌다. 본 증례는 상악 유견치의 선천적 결손을 지닌 2명의 환아에게서 각각 4세, 6세경 영구 견치가 조기 맹출 된 증례가 있어 보고하였다. 이러한 조기 맹출이 일반적이지 않더라도, 발생 시에 환자는 공간과 관련된 문제가 발생할 수 있으며 좀 더 주의 깊은 구강위생 관리가 필요하다. 이에 본 증례를 통하여 유견치 선천적 결손 후 후속 영구치의 조기 맹출 가능성에 대하여 보고하는 바이며, 조기맹출 시 발생할 수 있는 문제점과 관련하여 임상가들은 주의 깊은 관찰이 필요하다.
