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 undiffe...

혼합 치열기에는 어떤 노력이 필요한가? | 미성숙 영구치는 상대적으로 치수 조직의 부피가 크고 풍부한 혈류 공급을 받기 때문에 손상에 대한 치유 능력이 성숙 영구치에 비해 뛰어나지만, 치수의 생리학적인 환경에 영향을 주는 모든 요소들은 치근의 완성에 장해를 줄 수가 있다. 따라서 이 시기에는 치근의 발육에 있어서 중요한 역할을 하는 Hertwig's epithelial sheath (HERS)의 생활력을 보존하기 위해 모든 노력을 기울여야 한다.1) | |
현대 의학은 주로 어디에 초점을 두고있는가? | 현대 의학은 과거와 달리 질병의 예방과 회복에 그 초점을 맞추고 있으며, 이러한 보존적인 치료 방식이 실패한 경우에만 외과적 수술이나 인공적 보철물을 이용한 치료를 시행하고 있다. 또한 최근에는 병적인 조직을 제거한 후 잠재적인 발생 가능성이 있는 세포 또는 조직의 발생을 유도하여 조직 또는 기관을 원상태로 복구하는 치료와 줄기 세포를 이용하여 상실된 조직을 재생하는 치료에 관심이 집중되고 있다. | |
미성숙 치아의 보존적 치료 방법에는 무엇이 있는가? | 보존적 치료로는 직접 치수 복조, Cvek 치수 절단술, 치수 절단술, 근첨 형성 유도술, 근첨 형성술 등의 다양한 방법이 시행되고 있으며,1-6) 최근에는 치수에서 기원한 dental pulp stem cell (DPSC), 발치된 유치에서 기원된 stem cells from exfoliated deciduous teeth (SHED), apical papilla에서 기원된 stem cells from apical papilla (SCAP), 치주 인대에서 기원하는 periodontal ligament stem cells (PDLSC) 등 dental stem cell의 발견 및 그 배양 기술의 발달과 더불어 이러한 전통적인 치료 방법에도 새로운 견해가 나타나고 있다. Dental stem cell은 다른 줄기 세포들과 마찬가지로 자가 재생 능력과 다분화 능력을 가지며, 이 중 stem cells from exfoliated deciduous teeth (SHED)를 제외하고는 모두 영구치에서 발견되는 줄기 세포이다. |
