Abstract
|
|
|
Purpose: The purpose of this study was to compare histologic evaluation of autogenous and allogenous tooth material on bone-healing response in dog.
Materials and Methods: Allogenous tooth biomaterial was grafted in the extraction socket of the premolar region in the left lower jaws and autogenous tooth biomaterial was grafted in the right side after 2 weeks. Three dogs were sacrificed after 4, 8, 12 weeks each for histological evaluation.
Results: In the histologic analysis, there were no signigicant differences between group 1 (autogenous tooth bone biomaterial) and group 2 (allogenous tooth bone biomaterial) at 4, 8, 12 weeks. Statistical analysis showed that group 1 was more higher bone volume levels than group 2 at 4 weeks (P?0.05, Mann-whitney test). Group 2 showed more higher bone volume levels than group 1 at 8 weeks and group 1 more than group 2 at 12 weeks but that showed no significant differences (P¤0.05, Mann-whitney test).
Conclusion: Histologically, autogenous and allogenous tooth biomaterial reveals similar healing patterns in extraction socket in dogs. The result of this study suggested that tooth biomaterials could be useful materials for socket preservation.
