The influence of pulp status on the accuracy of TRR1 electronic apex locator
Abstract：Objective To investigate the influence of pulp status on the accuracy of determining root canal length by TRR1 electronic apex locator in clinic.Methods Two hundred and fifty-seven root canals of 87 teeth were divided into two groups, teeth in group A were diagnosed as pulpitis, and teeth in group B were apical periodontitis. All these root canals' working length were measured by TRR1 electronic apex locator, then measured the distance between the K-file tip and the radiographs(L), when 0 mm≤L≤2 mm,the data were considered accuracy. Results The accuracy rate of group A was lower than that of group B, but there was no significant difference in these data between two groups. Conclusion The accuracy of TRR1 electronic apex locator wasn't influenced by the pulp status in this study.
