de Molon RS, et al. - Authors gauged the sinus floor augmentation with two different particle sizes of demineralized bovine bone mineral (DBBM) by means of histological and immunohistochemical (IHC) analysis. The percentage of biomaterial, newly formed bone, or connective tissue did not differ significantly between the small- and large-sized particle groups, respectively; as seen in histomorphometric analysis. The expression of osteocalcin (OCN), vascular endothelial growth factor (VEGF), or tartrate-resistant acid phosphatase (TRAP) were not seen to differ on immunohistochemical (IHC) analysis. They noted the efficacy of both particle sizes of demineralized bovine bone mineral (DBBM) for bone augmentation in the maxillary sinus.
