Abstract
AIM: The aim of this study was to evaluate the inflammatory response to MTA Fillapex, AH Plus, and Pulp Canal Sealer Extensive Work Time (EWT), in a murine bone defect grafting model. MATERIALS AND METHODS: Bilateral mandibular critical defects were produced in 45 Wistar rats with a trephine bur#2 and filled with the endodontic sealers. After 7, 14, and 28 days, the rats were euthanized and their jaws were histologically prepared. RESULTS: For the 7-day group, no statistical significance was observed among all studied groups (p > 0.05), and high levels of inflammatory infiltrate were detected. After 14 and 28 days, Pulp Canal Sealer EWT showed statistically lower inflammatory response in comparison to other sealers (p < 0.05) except for the control group (no sealers). CONCLUSION: Pulp Canal Sealer EWT presented the lowest levels of inflammatory response. The critical defect grafting model was an effective method to detect differences among differences on the biological response to endodontic sealers. CLINICAL SIGNIFICANCE: Knowing the biocompatibility of endodontics sealers that will be used in filling the root canal.
