Microorganism survived in the root canal after root canal cleaning and shaping procedure is a main cause of root canal treatment failure. There are several mechanisms for the bacteria to survive in the root canal after chemomechanical preparation and root canal irrigation. Bacteria organized as biof...

치근단 질환은 무엇인가? | 치근단 질환은 근관을 통해 침투하는 세균에 의해 유발되어 지속되는 것으로써 원인을 제거하기 위해 적절한 protocol에 따라 근관치료를 시행하면 90% 이상의 경우 병소가 치유되고 증상이 소실되는 것으로 알려져 있다1-3). 세균에 의한 근관내 감염을 제거하기 위해서는 근관형성과 같은 기계적인 방법을 사용하거나 근관형성으로 도달하기 힘든 근관내 복잡한 해부학적 구조물 속에 있는 감염 치수 조직과 세균을 근관 세척액을 사용하여 제거하는 화학적 방법이 필수적인데 이 과정에서 치근단 조직에 가해질 수 있는 손상이나 자극을 최소한으로 억제하면서 동시에 근관을 무균 상태로 만들고자 하는 연구가 지속되어 왔다4,5). | |
세균에 의한 근관내 감염을 제거하는데 어떤 방법이 있는가? | 치근단 질환은 근관을 통해 침투하는 세균에 의해 유발되어 지속되는 것으로써 원인을 제거하기 위해 적절한 protocol에 따라 근관치료를 시행하면 90% 이상의 경우 병소가 치유되고 증상이 소실되는 것으로 알려져 있다1-3). 세균에 의한 근관내 감염을 제거하기 위해서는 근관형성과 같은 기계적인 방법을 사용하거나 근관형성으로 도달하기 힘든 근관내 복잡한 해부학적 구조물 속에 있는 감염 치수 조직과 세균을 근관 세척액을 사용하여 제거하는 화학적 방법이 필수적인데 이 과정에서 치근단 조직에 가해질 수 있는 손상이나 자극을 최소한으로 억제하면서 동시에 근관을 무균 상태로 만들고자 하는 연구가 지속되어 왔다4,5). 이렇게 실험실에서 행해지는 많은 연구는 결국 치근단 질환을 치유하고자 하는 목적에서 시도되고 있는 것이지만 실제 임상에서 근관치료의 성공률은 수십년 전의 성공률에 비해 그다지 높아지지 않고 있는 것으로 보인다. | |
근관치료 술식의 치료 성공률을 향상시키기 위해서는 무엇을 해야 하는가? | 물론 세균이 아닌 다른 요소에 의해 근관치료의 실패가 일어난다고도 할 수 있지만 그보다는 결국 체내의 면역반응에 저항하는 세균의 능력에 기인하는 것으로 보인다. 따라서 높은 수준의 치료 성공률을 지속적으로 유지하기 위해서는 위에서 언급된 바와 같은 제대로 된 치료 protocol을 따라 근관치료를 진행하면서 좀더 나은 결과를 얻기 위해 새로운 protocol을 개발하고 정립하는 과정이 계속되어야 한다. |
