Abstract:
Purpose:To histologically evaluate the effects of three calcium silicate-based sealers on rat mandible tissue.
Materials and Methods:Rats were randomly divided as follows: A group that sacrificed immediately after cavity preparation, a group that sacri-ficed two weeks after cavity preparation, a group that sacrificed two weeks after CeraSeal (CS), AH Plus Bioceramic (AHB), or OneFil (OF) sealer injection, respectively. After tissue processing for all groups, the bone tissue area (%) and the number of osteoclasts in and around the cavity were measured under a microscope. The results of each group were compared and statistical analysis was performed using one-way ANOVA and Tukey’s test.
Results:The formation of bone tissue and the presence of osteoclasts in the cav-ity were observed in the group that sacrificed two weeks after cavity preparation and the group sacrificed two weeks after AHB seal-er injection, and these groups showed significantly higher average bone tissue area (%) than the other groups. In the other groups, no inflammation or foreign body reaction occurred in the cavity, and no osteoclasts were observed.
Conclusion:All calcium silicatebased sealers used in this study showed a favorable bone tissue response when injected into the rat mandible. In particular, higher bone formation in the cavity was observed in AHB.
