Analysis of the long-term solubility and phases of five different root canal sealers in phosphate buffered saline: an <i>in vitro</i> study

AHP displayed the most favourable physicochemical stability, with minimal solubility and sustained crystallinity. AHPBC and CS also demonstrated stable long-term behaviour, whereas BRCS and MTAF showed greater solubility and structural changes. These findings suggest limitations in the long-term durability of these materials. These findings underscore the importance of sealer selection, particularly when considering long-term stability and the potential impact of material dissolution within the root canal system.
