ABSTRACT – A COMPARISON OF EFFECTIVENESS OF DIFFERENT SOLVENTS IN DISSOLVING ROOT CANAL SEALERS – AN IN-VITRO STUDY

ABSTRACT:
AIM: The aim of this study was to evaluate the dissolution effectiveness of Xylene, Endosolv, RC Solve and distilled water on three different endodontic sealers.

MATERIALS AND METHODS: The solubility of three types of root canal sealers (Sealapex, Endofill and AH-Plus) was assessed in Xylene, RC Solve, Endosolv and distilled water. A hundred and twenty samples of gutta-percha were prepared using a standardized stainless steel mould, filled with three sealer cements and subdivided into three groups for immersion in the different solvents tested (Xylene, RC Solve,  Endosolv) and distilled water (control group) for 10 minutes immersion period. The means of gutta-percha dissolution in the solvents were obtained by the difference between the pre-immersion original weight and the post-immersion weight in a digital analytical scale (Gehaka – AG2000) and data were statistically analyzed.

RESULTS: Endosolv was the most effective solvent followed by Xylene in AH-Plus and Sealapex groups. RC Solve showed the best dissolving capacity in Endofill, followed by Endosolv and Xylene. In distilled water, insignificant sealer dissolution was observed in all groups.
