Aim: Our research aimed to evaluate the difference in water sorption, water solubility and push out bond strength between three bioceramic sealers (CeraSeal, NeoSEALER Flo, Well Root ST) with (AH plus).
Materials and methods: For water sorption and solubility, we prepared thirty-two discs and incubated until complete setting. According to the type of sealer, they were divided into four groups (n=8). The percentage of water sorption was calculated utilizing this formula: percentage of water sorption= (weight gained-initial weight /initial weight) x100. Percentage of water solubility = (water solubility / Dry weight) x100. For push out bond strength, instrumentation and irrigation were performed for forty single rooted teeth. Four groups were created according to sealer used. Cross-sectional cuts were made perpendicular to the root’s long axis for each specimen. The peak load observed was divided by the surface area to get the bond strength using the formula (A=(3.14 h (r1+r2)).
Results: For solubility, Ah plus showed lower solubility after 1 and 3 days but Ceraseal showed lowest solubility after 7 days. For water sorption, Neosealer Flo showed lowest water sorption after 1 day but AH plus showed lowest water sorption after 3 and 7 days. For push out bond strength, for coronal section, Ah Plus and Well-Root ST showed a significant highest push out bond strength in comparison with Ceraseal and Neosealer Flo. Conclusion: The bioceramic sealers had high water solubility and water sorption which allowed the release of biologically relevant ions. All the sealers bond strength meets the required standards.
