Abstract
The aim of the study is to conduct an evaluation and comparison of the ion release and interfacial adaptation of two bioceramic sealers (BS) and those are Dia-Root and NeoSealer Flo sealers in normal conditions (PBS) and in infectious conditions with the help of scanning electron microscopy (SEM) as well as energy dispersive X-ray spectroscopy (EDX). Methods: Slices of dentin which were 80 in number along with spaces of canals that are standardized were segregated into groups of two where the value of n for each was 40, and sealers like Neo Sealer as well as Dia-Root was used to fill them. There were specimens of 40 in each group and they were further divided into subgroups of two where the value of n is 20 with regard to the liquids used in experiment and their subjection to 1mmol per liter of butyric acid which has a pH value of 5.4 as well as subjection to PBS with a pH value of 7.4. Post which, an incubation of specimens for a period of seven days at a temperature of 37°C. With the aid of SEM, the evaluation of release of ions and the gap along the margins of the sealer as well as the interface of the dentin’s root was performed. Results: EDX of examined sealers subjugated to PBS showed mean Ca/P ratios that were greater than the natural HAP ratio (1.67). The NeoSEALER Flo sealer had a considerably reduced mean gap width than the DIA-ROOT sealer in an acidic environment where P ≤ 0.05. Whereas the standard deviation as well as mean for DIA-ROOT and NeoSEALER exposed to PBS were determined, DIA-ROOT BIO Sealer formed the smallest gap, and NeoSEALER Flo formed the largest gap. Conclusion: All examined sealers (Dia-Root and NeoSealer Flo) produce calcium, aluminum, and oxygen ions in all storage media. Acidic environments have an impact on the interfacial adaptation of the tested BS to perform root canaling on dentins.
