Histopathologic Responses of Dog’s Dental Pulp to Mineral Trioxide Aggregate, Bio Active Glass, Formocresol, Hydroxyapatite

摘要: Introduction : Bio Active Glass (BAG) is often used as a filler material for regeneration of dental bone defects. Mineral trioxide aggregate (MTA) retrofilling agent, repair root resorption and pulpotomy agent in primary dentition. Formocresol (FC) old standard fixation procedures. Hydroxyapatite (HA) biologic constitute. It ridge augmentation, bony defect teeth. The purpose this study was evaluation histopathologic responses dog’s pulp to MTA, BAG, FC HA after three months follow up. Materials Methods For experimental prospective forty-eight teeth were randomly selected four dogs. Animals anesthetized pulpotomized. Three later, animals sacrificed. Then, extracted histologic sections prepared. Histologic observed by an oral pathologist. from the view inflammation, hyperemia, necrosis, vitality, calcification dentinal bridge. Relative frequency outcomes analyzed reported. Mean differences groups Kruskal-Wallis Mann-Whitney tests. Results inflammation FC, BAG 29.2, 25.9, 42.4 29.2 percent, respectively. hyperemia 75.1, 63.6, 59.2, 81.6 62.5 necrosis 11.1, 12.1, 0 75, 51.9, 69.7 54.8 bridge 70.4, 30.3 Conclusion Histopathologic reactions materials (MTA, HA, FC) different. MTA more proper than those FC. Considering these findings, use mineral bioactive glass favorable using Hydroxyapatite.
