Histological study of the influence of bioactive glass on bone healing [an experimental study on rat femur]

ABSTRACT

The objective is to study the histological influence of the bioactive glass on bone healing in surgically created holes in rat's femur. The two wall holes were made in the right femurs by 2-mm drill, filled with bioactive glass in the examined rats. Another two wall holes were made similarly in the right femurs of other group of rats without filling with bioactive glass and used as the control group. Animals were regularly examined over a period of five weeks for bone healing. Histological examination of both control and treated sites showed newly formed bone. The newly formed ostoid tissue was significantly increased in the treated holes in the form of foci of newly formed bone around and within the glass particles. In the control group, the junctional epithelium migrated up to the base of the hole. The treated animals with bioactive glass had better healing than control. The bioactive glass particles have osteo-conductive property as well as osteo-stimulatory capacity. The graft material showed a promising inhibition of greater cementum deposition in the bone holes. We can use it in Osteosurgery as it can promote bone healing
