Histopathological, histomorphometrical, and radiological evaluations of hydroxyapatite/bioactive glass and fluorapatite/bioactive glass nanocomposite foams as cell scaffolds in rat tibia: an in vivo study.

Bone defects are common and persistent problems in clinical orthopedics and dentistry. The development of synthetic reconstruction materials is essential owing to the restricted access to natural bone grafts, disease transmission risks, surgical costs, donor-site morbidity, infections, and immune response-related complications. The present study was done to evaluate the histopathological, histomorphometrical, and radiological characteristics of composite foams containing hydroxyapatite/bioactive glass (HA/BG) and fluorapatite/bioactive glass (FA/BG) as cell scaffolds in rat tibia reconstruction. A total of 60 rats were divided into four equal groups, of which three groups were implanted with HA/BG, FA/BG, and CenoBone
