Comparative Evaluation of Effectiveness of Xylene and Acetate Containing Solvent in Dissolving Two Different Bioceramic Sealers: An In-Vitro Study

Abstract

Introduction: Due to rising popularity of bioceramic sealers, there is an increasing demand   for a solvent that is both efficient and safe for use in endodontic retreatment. However, there is limited information in the literature regarding the effectiveness of xylene and acetate-containing solvents in dissolving endodontic sealers.

Objectives: The study was aimed to evaluate and compare the effectiveness of xylene and acetate containing solvent in dissolving two different bioceramic sealers.

Methods: Standardized stainless steel molds were used to prepared the sixty samples (30             from each endodontic sealer). All samples were classified into Group I (CeraSeal) and Group II (MTA-Fillapex), with each group subsequently split into three subgroups according to immersion solution utilized. Ten samples from each group were immersed in a specific organic solvent for 2 minutes. Sample weight was recorded before and after immersion using a digital analytical scale.

Results: Amongst all groups, Group IIB (mta fillapex immersed in endosolv) shows the highest dissolution with (mean=0.065±0.0163) followed by Group IIA (mta fillapex immersed in xylen, mean=0,0426±0.024), Group IB (ceraseal immersed in endosolv, mean= 0.0074±0.009), Group IA (ceraseal immersed in xylene, mean=0.0038±0.009). Group IC (ceraseal immersed in distilled water, mean=0.0001±0.0001) and IIC (mta fillapex immersed in distilled water, mean=0.0002±0,0003) shows least dissolution with no significant difference between them.

Conclusions: Within the limitations of this study, an acetate-based solvent, demonstrated more effectiveness and they can use as an alternative to traditional solvents such as xylene.
