초록
치수 재혈관화 술식은 항생제를 이용하여 근관 내 감염된 조직을 무균 상태로 만들면 치근단에 존재하는 자가 재생 능력과다분화 능력을 가진 줄기 세포가 미완성 치근을 가진 미성숙 영구치의 치수 재생을 유도한다는 개념이 적용된 것이다. 이 술식은 치근의 길이와 두께가 증가하며 치근단의 폐쇄가 이루어진다. 비정상적으로 근관이 얇거나 만곡이 심해 전통적인 근관 치료시 어려움이 예상되는 경우, 전신 질환 등으로 인해 진정 요법을 시행하기 어려운 경우, 그리고 장애인와 같이 협조를 구하기 어려운 경우에서 치근단 치주염을 가진 미성숙 대구치의 치수재혈관화 술식을 고려해 볼 수 있다. 본 증례는 우식으로 인해 감염된 미성숙 제1대구치의 근관 내에 ciprofloxacin, metronidazole, minocycline의 3종의 항생제를 적용하여 치수 재혈관화 술식을 시도하여 양호한 결과를 보였기에 이를 보고하고자 한다.
Abstract
Revacularization of the pulp in a necrotic, infected immature tooth with apical periodontitis was attempting several years. Revasculization of partially necrotic pulp in an immature tooth is based on the concept that vital dental stem cells can survive pulpal necrosis. Revascularization procedure obtains longer and thicker roots in teeth with necrotic pulp diagnosis. Pulp revascularization for immature permanent molars can be possibly applied on cases having difficulty to use conventional root canal treatment due to abnormally thin root canal wall or severe root curvature. Also,when an uncooperative patient does not agree with sedative treatment the revascularization can be useful. And a patient with disability who is barely cooperative can be another indication of this treatment. In this case report, pulp revascularization using triple-antibiotics, metronidazole, ciprofloxacine and minocycline,was applied on the immature first permanent molar infected by caries.
