A Comparative Study of pH Changes, Releasing Elements and solubility of Bioceramic Sealers.

Abstract:
 Introduction: Bioceramic technology has been introduced recently in endodontics to benefit from the hydroxyapatite formation during setting reaction presence of tissue fluid and establish a chemical bond at dentin interface.
 Aim: To compare physiochemical properties (pH changes, releasing elements solubility) different newer sealer (Ceraseal) with mineral trioxide aggregate (MTA-Fillapex) sealers.
 Material Method: Samples were prepared by using three injectable placed 20 ring moulds, 10 each sealer. Each sample was an internal diameter mm height 3mm. The samples digitally weighed register mass specimen before after immersion distilled water. pH value measured digital meter, atomic absorption spectrophotometer, solubility machine. After 1, 7, 14 28 days, released data obtained calculated statistically analysed.
 Results: Ceraseal Sealer exhibited high alkaline over time also showed significantly higher (P < 0.05).
 Conclusion: shows more alkalinity calcium ion release compared MTA nature bioceramic sealer, corresponds increase solubility. So are alkaline, soluble.
