Evaluation Of Root Zx, Apex Id, Propex Pixi And Raypex 6 In Teeth With Wide Apical Foramen An In-Vitro Study.
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2018, Vol 3, Issue 4
Abstract
Aim: To evaluate the efficacy of ROOT ZX, APEX ID, PROPEX PIXI, and RAYPEX 6 apex locators in determining working length with different apical diameters (at 0.0, 0.32, 0.57, 0.72mm apical widening) Materials and methods: Sixty extracted single rooted premolars were included in the study. Actual working length was determined by observing under 20X magnification with help of RAPID I microscope until 10 K file was visible at apical foramen. File was withdrawn 0.5mm from this point, stopper adjusted, file was removed and length was measured. Teeth were divided into four groups depending on the apical diameters: Group I (n=15): Canals with no preparation. In GROUP II, III & IV, after enlarging the canal, file was advanced beyond 1mm. Group II (n=15): Canals were enlarged until size 30 K-file. Group III (n=15): Canals were enlarged until size 55 K-file. Group IV (n=15): Canals were enlarged until size 70 K-file Root canal measurements with electronic apex locators (EALs) were recorded. Statistical analysis was performed using Fisher exact test & one way anova. Significance was set at P < 0.05 Results: There was no statistically significant difference between the accuracy of four different apex locators, but there was significant difference seen between Group I and Group IV. Conclusion: The electronic apex locators can be used, only as an adjunct to radiographs in determining the working length of teeth with wide apical diameters. Raypex 6, newer generation apex locator performed best in present study.
