The Potential of Natural Propolis Extract Combined with Bovine Bone Graft in Increasing Heat Shock Protein 70 and Osteocalcin on Socket Preservation.

Objective:  This study aims to combine natural propolis with bovine bone graft (BBG) as a means of extraction socket preservation after 3 and 7 days toward expression of heat shock protein (HSP) 70 and osteocalcin to regenerate bone.
Materials and Methods:  The Cavia cobaya were divided into eight groups, each consisting of seven samples. Their lower left incisors were extracted and induced with PEG, propolis extract, BBG, and a combination of propolis extract BBG. The research subjects were terminated on days 3 and 7 postextraction. Immunohistochemical and histopathological examinations were subsequently performed to observe HSP 70 expression, osteocalcin expression, osteoblasts, and osteoclasts.
Statistical Analysis:  Data obtained were then analyzed with one-way analysis of variance (ANOVA) and Tukey's honestly significant difference (HSD) tests.
Results:  Both the groups with the combination of propolis extract and BBG on days 3 and 7 were found to present the highest number of HSP70 expression, osteocalcin expression, and osteoblast cells as well as the lowest number of osteoclasts.
Conclusion:  Both the groups with the combination of propolis extract and BBG on days 3 and 7 were found to present the highest number of HSP70 expression, osteocalcin expression, and osteoblast cells as well as the lowest number of osteoclasts.
