치수/치근단 질환에 이환된 영구치의 치수 조직 재생과 치근 형성 = PULP TISSUE REGENERATION AND ROOT FORMATION OF PERMANENT TEETH WITH PULPAUPERIAPICAL DISEASES

국문 초록 (Abstract)

최근 치수 질환 또는 치근단 질환을 가진 미성숙 영구치에 대한 보존적 치료의 방법으로 여러가지 근관 내 소독 약제를 이용하에 증상 개선은 물론 치근의 성장 및 치수의 재생이 이루어진 증례들이 보고되고 있다. 그 기전에 대해서는 아직 명확하게 밝혀지지는 않았지만 여러가지 줄기 세포 또는 미분화 간엽 세포들이 관여하는 것으로 생각되며, 실제로 재생된 조직에서는 대부분백악질양또는골양물질의 침착이 관찰되고 있다. 이 새롭고보존적인 치료접근 방법은 다능성 줄기 세포와 다양한조직 공학 기술에 대한 연구와 더불어, 재생적 근관 치료에 더 밝은 비전을 제시하고 있다.

다국어 초록 (Multilingual Abstract)

Numerous cases about additional growth of roots or pulp tissue regeneration by using various intracanal medicaments in immature permanent teeth with periapical or pulpal disease have been reported. The underlying mechanism has not been clearly delineated. but it has been widely accepted that undifferentiated mesenchymal cells and stem cells are involved. Moreover, the growth and deposition of osteoid or cementoid tissues have been observed in regenerated pulp and roots. This new and non-invasive treatment has brightened the future of endodontics. and enlarged the vision of regenerative root canal treatment with multi-potent stem cells and various tissue engineering techniques.
