Biosealer versus Biodentine for direct pulp capping in dog’s teeth: A histopathological evaluation

Abstract BackgroundThis study compared the effect of Biodentine (BD) and Tech Biosealer Capping (BS) on the pulpal tissue response after pulp capping in dogs, teeth.MethodsThree mongrel dogs were enrolled in this study. Class V cavities with pulp exposure were performed on the buccal surface of 30 teeth (2 experimental groups) and left without pulp exposure in 15 teeth (control group). The cavities of experimental groups were capped with either Biodentine (BD Group, N= 15 teeth) or Tech-Biosealer Capping (BS Group, N= 15 teeth). All cavities (experimental and control groups) were restored with resin-modified glass ionomer. Dentine bridge formation, architechecture of the odontoblastic layers and signs of inflammation were assessed after 1, 2 and 3 months using the computer image analyzer (Leica Qwin 500).ResultsBD group showed a thick newly formed reparative dentin bridge completely closing the exposure site with cell inclusions and mineralization, variable amount of odontoblast-like cells, preserved pulp tissue, marked numerous collagen fibers and blood vessels. While BS group showed an incomplete newly formed reparative dentin bridge with tunnel defect, vacuolated odontoblasts, complete pulp degeneration with multiple edematous spaces, hyperemic blood vessels, extravasated RBCs, multiple calcified structures scattered just beneath the dentin bridge and through the pulp tissue, and newly ill-defined odontoblasts.ConclusionFor pulp capping, Biodentine has better dentine bridge formation and pulp preservation than Tech Biosealer Capping.
