PURPOSE The purpose of this study was to evaluate the accuracy of the Root ZX electronic apex locator in determining canal length in primary incisors. METHODS Root ZX was utilized to measure the canal lengths of 150 primary incisors in vivo. After the teeth were extracted, a standard ruler was used to measure the canal lengths to the nearest 0.5 mm. A paired t test was used to compare the lengths obtained in vivo with Root ZX and the lengths measured in vitro. RESULTS In 98 (65%) of the… CONTINUE READING
