초록

치수괴사가 있는 미성숙 치아를 치료할 때 많은 도전을 받는데, 역사적으로 수산화칼슘을 장기간 적용하여 석회 차단벽의 형성을 유도하는 것이 사용되어 왔다. 2004년 개방성 근첨을 치료할 수 있는 '재혈관화'라는 새로운 방법이 소개되어 널리 인정받게 되었다. 기존의 근첨형성술과 이 방법이 다른 점은 근관을 세 항생제 (ciprofloxacin, metronidazole and minocycline)로 소독하고 인위적으로 근관내 출혈을 유도한 다음, MTA로 밀폐한다. 괴사된 미성숙 영구치를 재생 근관치료를 성공적으로 하였을 경우, 지속적인 치근의 성장과 상아질벽 두께의 증가, 및 치근첨의 폐쇄를 얻을 수 있다. 이는 치수-상아질 복합체의 기능적 회복과 발달이 궁극적으로 자연치의 유지에 기여하는 점이다.

Numerous challenges in treating permanent dentition are encountered, especially in treating immature teeth with pulp necrosis. Historically, calcium hydroxide application during long periods of time was used to induce the formation of a calcific barrier across the open apex. In 2004, a new treatment modality for the management of the open apex was introduced. This treatment was named as 'revascularization' and gained acceptance among dentists. The protocol was different from the traditional apexification techniques in that the canal was irrigated and disinfected with a combination of three antibiotics (ciprofloxacin, metronidazole and minocycline). At the next appointment, bleeding was induced and the canal was sealed with MTA. Successful regenerative endodontic treatment of necrotic immature permanent teeth can provide continued root development, increased thickness in the dentinal walls and apical closure. These developments of a functional pulp-dentin complex have a promising impact on retaining the natural teeth, the goal of the dental health care.
