Comparison of Gutta Percha Removal with Manual H-Files and ProTaper with or Without Eugenate

Abstract

Objective: To compare manual H-File with ProTaper Retreatment files for the abolition of Gutta Percha filling material from the root canals with or without solvent use (Eugenate). Study Design: Quasi-experimental study. Place and Duration of Study: Operative Dentistry Department, Armed Forces Institute of Dentistry, Rawalpindi Pakistan, from Sep 2019 to Feb 2020. Methodology: Forty mandibular premolars with previously failed root canal treatment were chosen. They were randomly divided into four groups, each with ten teeth. Gutta-percha filling material elimination was done with manual H-Files and rotary ProTaper with and without Eugenate and evaluated radiographically. The time duration for complete removal was also noted and evaluated by stopwatch. Results: Out of the total 40 patients 22(55%) were female and 18(45%) were males. Comparison of mean operating time duration of elimination of Gutta Percha filling material from the canals was less with ProTaper with Eugenate compared with the other three groups; however, it showed statistically significant differences among groups (p<0.05). Conclusion: Every group showed some residual filling material in the canals. ProTaper D retreatment files with Eugenate performed faster than ProTaper alone, followed by manual H-files without Eugenate and Eugenate
