Comparative evaluation of dissolution of a new resin-coated Gutta-percha, by three naturally available solvents

Introduction: The aim of this study was to evaluate and compare the effectiveness of eucalyptus oil, orange oil, and clove oil in dissolving resin-coated Gutta-percha (RCGP) cones. Materials and Methods: RCGP cones (EndoREZ,) (n = 70) and conventional GP cones (n = 70) with ISO size 25 and 4% taper were used for the study. Cones of each type were divided into three groups of twenty each, for immersion in eucalyptus oil, clove oil, and orange oil for 5 and 15 min immersion times. Ten GP cones from each group served as control and were immersed in distilled water. Each sample was weighed initially before immersing in the respective solvents. Cones were removed after specified immersion period, washed in distilled water, and allowed to dry. The samples were then re-weighed and statistical analysis was done. Results: Orange oil was most effective in dissolving both RCGP and conventional GP when compared to eucalyptus and clove oil. RCGP dissolved more readily than conventional GP in orange oil. Conclusion: Orange oil was the most effective solvent of EndoREZ RCGP and conventional GP among all tested solvents.
