Abstract Aim To evaluate the influence of pH variation on solubility and water sorption a premixed calcium silicate‐based root canal sealer (EndoSequence BC Sealer) compared to gold standard based epoxy resin (AH Plus Jet) after immersion in distilled phosphate‐buffered saline (PBS). Methodology Solubility were evaluated or PBS at several pHs (5, 7 12) values calculated as percentages original mass 24 h, 30 days immersion. The crystalline structures present sealers surface precipitates assessed by X‐ray diffraction. Shapiro–Wilk’s test revealed that data normally distributed; thus, statistical analysis was performed using one‐way anova Tukey’s tests independent t ‐test, assuming 5% α‐error. Results EndoSequence Sealer associated with significantly greater AH Jet all tested conditions ( P < 0.05). acid environment increased h immersed 0.05) did not induce significative changes > Alkaline reduced experimental times soaking media also Immersion Precipitates corresponding hydroxyapatite carbonate detected 5 for days. Conclusions had than Jet. Although alkaline directly influenced sealers, remained within limits recommended ISO 6876, whilst comply recommendations tested.
