Physicochemical Properties of Four Bioactive Root Canal Sealers

Abstract

The purpose of present study was to assess and to compare the physicochemical properties of four bioactive root canal sealers. Materials and Methods: four bioactive root canal sealers that are available on the market were tested (Well-Root; Apexit Plus; Dia-Root and MTA Fillapex). The initial and final settin g time was determined by Gilmore needle. Flow Test and solubility test conducted according to ISO standard 6876. The film thickness was determined according to the ISO 3107 standard. pH measurement for different sealers that immersed in deionized water at 5minutes, 1h, 12h, 24h and 48h time intervals. Fourier transform infrared spectroscopy (FTIR) analysis was done for the chemical structure of set samples for tested sealers. Data were analyzed by ANOVA and Tukey's tests (p˂0.05) using SPSS. Results: The setting time of Well-Root significantly less than other sealers (p=0.00) for both initial and final setting time. Higher flow mean value presented with Well-Root and MTA Fillpex compared with than Apexit plus and Dia-Root respectively. Well-Root sealer shows significantly more solubility than other tested sealer. Film thickness of Well-Root sealer significantly less than other sealers. Well-Root sealer showed the highest alkaline value at all evaluation time followed by Dia-Root, Apexit Plus and MTA Fillapex , respectively. FTIR analysis revealed the chemical composition similarity and difference in set samples observed with change in intensities of the peaks. Conclusion: All the tested bioactive root canal sealers showed acceptable physicochemical properties.
