Effect of different endodontic solvents on the effectiveness of two electronic apex locators – An in vitro study

Aim: The aim of this in vitro study was to determine the influence of different endodontic solvents on the accuracy of two electronic apex locators in locating the apical foramen. Materials and Method: Eighty human permanent maxillary central incisor teeth were divided into four groups (N=20) according to solvent used and two subgroups according to apex locator used viz; Propex II and Root ZX mini, Group I-Endosolv R, Group II-RC solve, Group III- Eucalyptus oil, Group IV- Chloroform. Results: Statistical analysis using Cochran’s Q test and Mann-Whitney U test showed insignificant difference between four endodontic solvents for both electronic apex locators. Conclusion: Within the limitations of this study, Solvents used do not interfere with the functional ability of both the electronic apex locator with no difference between the ability of them to locate the apicalforamen.   Key Words: Electronic Apex locator, Working length, Radiographic apex, Apical foramen, Endodonticsolvent.
