A longitudinal comparative histometric study of the biocompatibility of three local hemostatic agents
Abstract
The biocompatibility was studied of 3 hemostatic agents (Astroplast, Hemastogen and bone wax) implanted into experimental bone cavities together with their clearance from the implantation sites. The 3 agents had an acceptable hemostatic effect during the surgical procedure. However, marked differences regarding tissue reactions in the experimental bone cavities, as well as at the internal bone surfaces, were found between them. Astroplast and Hemastogen appear to provoke more adverse tissue reactions, including foreign body giant cell formation, compared with bone wax. All 3 hemostatic implants showed markedly delayed bone healing. It was concluded that their biocompatibility was not ideal but acceptable in view of the clinical advantages.
