Table 1 All methods excluded perforations when they were not present (100% specificity; 95% confidence interval [78%; 100%])

From: Accuracy of electronic apex locators to detect root canal perforations with inserted metallic posts: an ex vivo study

Device Sensitivity with 95% confidence interval Specificity with 95% confidence interval
ProPex II 93% [68%;100%] 100% [78%; 100%]
Elements Apex Locator 93% [68%;100%] 100% [78%; 100%]
Apex NRG 100% [78%; 100%] 100% [78%; 100%]
RayPex 5 100% [78%; 100%] 100% [78%; 100%]
RayPex 6 93% [68%;100%] 100% [78%; 100%]
  1. The Apex NRG and RayPex 5 also detected all perforations (100% sensitivity; 95% confidence interval [78%; 100%]). The ProPex II, Elements Apex Locator, and RayPex 6 detected 14 of 15 perforations (93% sensitivity; 95% confidence interval [68%;100%]).
