초록

근단부위 형성이 완료되고 우식이 없는 하악 대구치 근심치근 50개를 대상으로 주파수 의존형 전자근관장 측정기를 이용하여 측정한 근관장의 정확도를 평가하기 위해 치수강 개방 후 동일한 치아에서 방사선 사진으로 확인한 실측 근관장을 대조군, 각종 전자근관장 측정기로 측정한 근관장을 실험군 (I군: Root-ZX, II군: Bingo, III군: Propex, IV군: Diagnostic) 으로 분류하여 근심협측과 설측의 근관장을 근관의 입구 측으로부터 치근단 1/3까지 확대여부 및 서로 다른 측정시기에 측정하여 비교 평가한 결과 다음과 같은 결론을 얻었다. 하악 대구치 근심치근의 협측과 설측 전자근관장은 측정기의 종류, 근관의 입구 측으로부터 치근단 1/3까지의 확대여부 및 측정시기에 상관없이 0.5 ㎜ 이내의 오차범위를 나타내었으며, 근관치료시 오차한계인 ±1 ㎜ 에서 정확성은 근관의 입구 측으로부터 치근단 1/3까지 미리 확대한 후에 근관장을 측정할 경우와 측정시기가 반복될 경우에 증가되는 경향을 보여 임상에 유용하게 활용할 수 있을 것으로 사료된다.

Abstract

The aim of this study was to compare the length between the mesio-buccal and mesio-lingual canal of the mandibular molars before and after early coronal flaring at the different measuring time using several electronic apex locators. Fifty mandibular molars with complete apical formation and patent foramens were selected. After establishing the initial working length of the buccal and lingual canal of the mesial root using a surgical microscope(Carl Zeiss Co. Germany) at 25X with #15 K-file tip just visible at the foramen, radiographs were taken for the working length. After measuring the length of mesio-buccal and mesio-lingual canal(control group), the electronic lengths were measured at different times using several electronic apex locators(experimental groups; I-Root ZX, II-Bingo, III-Propex, IV-Diagnostic). After early coronal flaring using the K3 file, the additional electronic lengths were measured using the same manner. The results were as follows: One canal has a correct working length for the mesial root of the mandibular molar, it can be used effectively for measuring the electronic working length of another canal when the files are superimposed or encountered at the apex. In addition, the accuracy of the electronic apex locators was increased as the measurement was accomplished after the early coronal flaring of the root canal and the measuring time was repeated.
