Evaluation of flow, Ph and solubility of a new calcium silicate-based sealer: A comparative in-vitro study

Abstract

The physical properties of sealers were evaluated for flow, setting time, radiopacity, dimensional stability, PH change, and solubility. Thus, the aim of this study was to compare a new calcium silicate-based sealer (Ceraseal) with 2 well established root canal sealers (MTA Fillapex & AH Plus) based on their flow, alkalinity and solubility. Three already established root canal sealers (MTA Fillapex, Ceraseal & AH Plus) were assessed for flow, alkalinity and solubility among 40 samples. For flow evaluation and pH evaluation 15 samples each were used, and for solubility test 10 samples were used. Statistical analysis was performed using t test and Tukey parametric tests after evaluating the normality of data. The significance level was set at 5%.AH plus showed maximum flow among all the sealers followed by MTA fillapex and Ceraseal. It was found that maximum pH was seen among ceraseal root canal sealer at 72 hours. When MTA Fillapex and ceraseal were compared the results were not significant statistically, except at 72 hours. The maximum solubility was seen among ceraseal sealer followed by MTA Fillapex and AH Plus. The results were significant statistically. Ceraseal had acceptable flow and an alkaline pH while also having a greater solubility, which may be a sign of its bioactivity given the limits of this in vitro investigation.
