초록

본 연구는 레진 블록에서 엔진구동형 Ni-Ti기구를 이용하여 근관성형 후 Buchanan plugger의 삽입 깊이에 대한 비교를 통해 임상적 상황에서 Ni-Ti 파일로 근관 성형 후 Continuous wave of condensation technique을 이용한 근관 충전시 적절한 크기의 Buchanan plugger 선택에 지침을 제공하기 위해 시행되었다. 만곡근관과 직선근관을 가진 레진 블록에서 ProTaper와 ProFile을 이용하여 근관 성형을 하였다. 성형 후 근관에 Buchanan plugger가 근관벽과 처음으로 접촉하는 부위까지 삽입한 후 그 상태에서 스캐너를 이용하여 이미지를 얻었다. 이미지 분석 프로그램을 이용해 근첨에서 plugger 첨부까지의 거리를 얻었다. 각 기구에 대한 plugger 삽입깊이에 대한 유의성을 검정하기 위해 one-way ANOVA를 시행하였고, 사후검정을 위해 Scheffe's test를 시행하였다. 본 연구의 결과 만곡되고 좁은 근관에서, ProTaper F2와 F3로 마무리 성형한 근관에서 F, FM크기의 plugger를 사용할 경우 Continuous wane of condensation technique으로 적절한 근관충전이 가능함을 시사하였다.

This study was conducted to evaluate the insertion depth of Buchanan plugger after shaping by various Ni-Ti rotary files. It was conducted to determine which size of plugger are appropriate, when root canals are shaped with Ni-Ti rotary files and obturated by Continuous wave of condensation technique. Two type of eighty simulated resin blocks were used : J-shaped and straight shaped canal. The simulated canals were instrumented by ProTaper and ProFile. Buchanan pluggers were inserted into the canal, and then the image was recorded to scanner. The distance from the apex of the canal to the plugger tip was measured by image analysis program. Data were analyzed by one-way ANOVA followed by Scheffe's test. The results were as follows 1. In straight canal finished up to ProTaper F2 and F3 file, F and FM pluggers were inserted more than 5 mm short of working length. 2. In J-shaped canal finished up to ProTaper F2 file, F pluggers were inserted more than 5 mm short of working length. Finished up to ProTaper F3 file. F and FM pluggers were inserted more than 5 mm short of working length. 3. In straight and J-shaped canal finished up to ProFile .06/#20 and .06/#25, any of Buchanan plugger could not be inserted more than 5 mm short of working length. These results suggest that canals shaped by ProTaper could be obturated by Continuous wave of condensation technique with F and FM size Buchanan plugger.
