초록
유치의 치수 감염을 적절히 치료하지 않으면 영구 계승치의 저형성이나 저석회화 같은 법랑질 형성부전, 치배의 위치변화, 맹출 부진이나 맹출 정지 같은 많은 합병증을 초래할 수 있다. 이 중에서도 계승 영구치배의 위치변화는 선행 유치의 변성된 치수로 인한 위치변화가 가장 많다. 본 증례는 조선대학교 치과병원 소아치과에 내원한 환아 중 유전치의 치근단 병소로 인해 계승영구전치 치배의 위치변화가 초래된 것으로 사료되어 유치 치료의 중요성을 문헌고찰과 함께 보고하는 바이다.
Abstract
The effect of primary tooth infection on permanent teeth was reported by many previous study. It is seen histologic change in the enamel forming organ and in the surrouding sac, thus produce the defect as either hypoplasia or hypocalcification and alter the eruption of the permanent teeth. The periapical inflammation cause permanent tooth displacement in various direction and can be classified into the three categories : rotation, deflection, inversion. This study reported case which displacement of succedaneous teeth may be caused by periapical infection of primary dentition and concluded that treatment procedure of infected primary tooth is selected and performed by importance to retain the tooth for space maintain, possibility to successfully restored, evidence of abnormal developement of the succedaneous tooth.
