초록

치내치는 치아 조직이 석회화되기 전에 법랑기가 치유두 내로 함입되어 형성된 발육성 기형이다. 가장 널리 통용되는 치내치의 분류법은 방사선 사진 상에서 함입(invagination)이 얼마나 치관에서 치근 쪽으로 연장되어 있는지에 따라 분류하는 Oehler's classification system이다. 그 중 Oehler's classification type III는 함입이 치근까지 연장되어 치주인대와 직접적으로 'pseudo foramen'을 통해 교통하는 경우를 말하며 대체로 치수와는 독립적으로 존재한다. Type III 함입을 통한 감염은 언제나 치주조직의 염증성 반응을 야기할 가능성이 있으며, 이처럼 'pseudo foramen' 주위로 염증성 병변이 발생한 경우 이를 'peri-invagination periodontitis'라 한다. 본 증례는 Oehler's type III 치내치를 갖는 상악 측절치의 'peri-invagination periodontitis'을 주소로 내원한 두 환자에게 각각 다른 치료적 접근을 통하여 양호한 결과를 얻었다. 치내치에 대한 처치 시 조기 진단과 예방적 치료를 통한 치수의 건강 유지가 매우 중요하나, 이미 치수까지 질환에 이환 되었을 경우 환아의 나이, 치근 성숙도, 함입의 종류, 염증의 치수 이환 여부 등을 고려하여 치료계획을 수립해야 한다.

Dens invaginatus is a developmental anomaly resulting in a deepening or invagination of the enamel organ into the dental papilla prior to calcification of the dental tissues. The most widely used classification of dens invaginatus is the system described by Oehler categorizes invaginations into three classes as determined by how far they extend radiographically from the crown into the root. Oehler's classification type III is that the invagination extends through the root and communicates with the periodontal ligament. There is usually no communication with the pulp. In Type III lesions, any infection within the invagination can lead to an inflammatory response within the periodontal tissues giving rise to a 'peri-invagination periodontitis'. In the cases presented here, we treated two patients who were refered for 'peri-invagination periodontitis' on maxillary lateral incisor with Oehler's type III invagination by different approaches each, and they have shown satisfactory outcomes. Although there are several approaches to the management of dens invaginatus, the most important objective is to preserve the health of the pulp, which can be achieved by early diagnosis and the prophylactic treatment regardless of severity. When disease has developed, decision has to be made whether to treat the invagination and the pulp separately.
