초록
치근천공은 근관치료시 종종 발생되는 사고로서 치근과 치주조직과의 개통을 의미하며, 치과의사에 의하여 우발적 또는 의도적으로 발생된다. 성공적인 치근천공의 치료로서 즉시 천공부위를 충전하여 감염을 방지하는 것이 중요한데 이러한 목표를 위하여 치근천공의 발생 시간, 크기 및 위치에 대한 고려가 필요하다. 치근천공의 진단을 위하여 직접 육안으로 출혈을 관찰하거나 방사선검사 또는 천공위치를 파악하는 보조적 방법 등이 유용하며, 치료로서 비수술적 또는 수술적 방법이 사용될 수 있다. 본 증례는 전북대학교 소아치과에 내원한 환자에서 영구전치의 치근 치경부에서 치근 천공이 일어난 경우로서 보존적인 접근을 통해 양호한 결과를 얻었기에 보고하는 바이다.
Abstract
Root perforations that result in a communication of the root space with the periodontal tissues occasionally occur during endodontic procedures. They may be induced iatrogenically. Successful treatment depends mainly on immediate sealing of the perforation and prevention of infection. Several factors affect the achievement of these goals, most important of which are: time of occurrence, size and location of the perforation. Identification of root perforations is possible by direct observation of bleeding, radiography and an apex locator. Perforation defects may be repaired by nonsurgical or surgical techniques. We report two cases of root perforation. One was treated by glass ionomer, other was treated by composite resin with calcium hydroxide.
