Accuracy of three different apex locators: A clinical study
Aim: To compare the accuracy of three different electronic apex locators (EALs) in patients treated for three different endodontic diagnoses. Methodology: Research was performed on 418 endodontic patients, aged 20-58. Initially, each tooth was diagnosed for pulpitis (P), being necrotic without (N) or necrotic with (AP) periapical pathosis, respectively. Working length (WL) was randomly determined with three EALs: ES-02 and ES-03 (Artonic, Zagreb, Croatia) and ProPex (Maillefer, Ballaigues, Switzerland). A total of 794 roots was analysed (245 roots P, 323 roots N, 126 roots AP). Following root filling the distance between the radiological apex and the end of the root-filling was assessed radiographically. Those roots where the fillings ended within 1.5 mm from the radiological apex were deemed as having an accurate WL. The data was statistically analyzed and non-parametric Kruskal-Wallis and Mann-Whitney were used as a post-hoc test. Results: Kruskal-Wallis tests showed that all three EALs were, regardless of make or technical principle, equally accurate in all three diagnoses. They showed no differences in roots with P (χ2 = 2.18 ; df = 2 ; p > 0.05), neither in roots with N (χ2 = 0.63 ; df = 2 ; p > 0.05), nor in roots with AP (χ2 = 3.62 ; df = 2 ; p > 0.05). However, diagnosis-related, Mann-Whitney tests showed that inaccurate WLs were significantly more frequent in roots with AP than in roots with N (Z = 6.47 ; p < 0.05) and roots with P (Z = 8.60 ; p < 0.05) ; inaccurate WLs were more frequent in roots with N than in roots with P (Z = 3.30 ; p < 0.05), for all three EALs. Conclusions: Regardless of make or technical principle, all three EALs are equally accurate ; however, in relation to different diagnoses, they uniformly demonstrated the same degree of discrepancy.
