Online published on 25 April, 2017. Abstract Objectives The purpose of this study was to assess in vitro effect of commonly used gutta-percha solvents on the micro hardness of radicular dentin. Materials and method 48 teeth were decoronated and root dentin was treated with Xylene, Endosolv-E, and Endosolv-R. Treatment consisted of exposing the specimens for 5 or 15 minutes to the test solvents. Saline-treated specimens served as controls. After each treatment period, the specimens were rinsed, dried, and prepared for Vicker's micro hardness analysis. Vicker's micro hardness values for each specimen were recorded before and after treatment, and the differences were statistically compared. Results A statistically significant decrease in radicular dentin micro hardness was found in most solvent-treated groups; the amount of the decrease was directly related to the exposure time. Conclusions Xylene, Endosolv-E and Endosolv-R may cause a significant softening effect on radicular dentin. This softening is already apparent after 5 minutes of treatment.
