Abstract

The purpose of this study was to evaluate the accuracy of Root ZX and Sybron Mini in determining the working length using 2.5% Sodium Hypochlorite, 2% Chlorhexidine gel and saline. Donnelly's gelatin technique was used for measuring twenty extracted human teeth. Electronic working length was measured at the display 0.5 and 0.0 level of each electronic apex locator using a digital caliper to the nearest 0.01 mm. Each measurement was repeated for each different irrigants. Accuracy of Sybron Mini was not significantly different from the Root ZX in the three different irrigants, and there was no significant difference in the accuracy of electronic apex locators among the irrigants when used as recommended by manufacturer (measuring electronic working length at 0.0 level of Sybron Mini and at 0.5 level of Root ZX).

본 연구의 목적은 근관세척제로 2.5% Sodium Hypochlorite, 2% chlorhexidine gel, 식염수를 사용하였을 때, Root ZX와 Sybron Mini의 근관장 측정의 정확도를 평가하고자 하는 것이다. 20개의 발치된 사람 치아에서 Donnelly의 gelatin technique으로 측정하였다. Digital caliper를 이용해 0.01 mm 단위까지 각 전자 근관장 측정기의 0.5와 0.0 level에서 전자 근관장을 측정하였다. 각 측정은 세척제 종류에 따라 세 번식 반복해서 측정하였다. 세 가지 세척제에서 Sybron Mini와 Root ZX의 정확도는 유의한 차이가 없었으며, 제조사의 지시 (Sybron Mini의 0.0 level과 Root ZX의 0.5 level)에서 전자 근관장 측정)에 따라 사용되었을 때 세척제에 따른 전자 근관장 측정기의 정확도는 유의한 차이가 없었다. Root ZX와 Sybron Mini의 사용 시 제조사의 지시대로 사용한다면, 근관세척제으로서 2.5% Sodium Hypochlorite, 2% chlorhexidine gel, 식염수의 사용은 근관장 측정의 정확도에 영향을 미치지 않는다.
