초록
구개치은발육구는 상악 전치에 나타나는 이상 치근 형태의 하나로 구개측 결절부에서 구개치은발육구를 관찰하였으며, 이 구는 치근단을 향하여 여러 깊이와 길이로 연장될 수 있다. 구개치은발육구는 세정되기 어렵고 청결이 불가능하여, 치태와 치석등이 축적되어 접합상피의 파괴를 일으키고 빠르게 골연하 결손부가 발생할 수 있다. 또한 이차적으로 치수 조직을 이환시켜근관-치주 병소가 발생할 수 있다. 본 증례 보고는 구개치은발육구로인해 근관 문제까지 야기된 임상증례를 보고하고 근관치료와 함께 여러가지 재료를 이용한 구개치은발육구의 치료결과를 관찰함으로써 이러한 치료방법의 효용성을 평가하고자 하였다.
Abstract
Objectives: Palatogingival groove is a developmental anomaly that starts near the cingulum of the tooth and runs down the cementoenamel junction in apical direction, terminating at various depths along the roots. While frequently associated with periodontal pockets and bone loss, pulpal necrosis of these teeth may precipitate a combined endodontic-periodontal lesion. This case presents a case of a lateral incisor anatomically complicated with palatogingival groove. Methods: Two patients with lesion associated with the palatogingival groove were chosen for this report. Palatogingival grooves were treated with different restoration materials with endodontic treatment. Conclusions: Maxillary lateral incisor with a palatogingival groove may occur the periodontal disease with pulpal involvement. Elimination of groove may facilitate the periodontal re-attachment and prevent the recurrence. [J Kor Acad Cons Dent 2011;36(3):238-242.]
