Many types of bioactive materials are categorized as bone tissue substitutes for reconstruction and regeneration of bone defects, such as nano-hydroxyapatite. The objective of the present study was to radiologically evaluate the bone healing process in experimentally induced tibial defects in dogs treated with two different viscosity concentrations of nano-hydroxyapatite gel. Twelve adult, healthy Mongrel dogs were included. A critical size bone defect of 3–0.7 cm was induced surgically in the lateral border of the tibial bone of the right limb of all dogs enrolled in this study. The dogs were then categorized into two treatment groups: Group 1 (6 dogs): The defect was filled with prepared hydroxyapatite nanogel at a concentration of 33%, and Group 2 (6 dogs) hydroxyapatite nanogel at a concentration of 24% was used as a filling material. The healing process of the tibial defect and associated clinical and radiolographical findings were recorded in all studied groups at 30 and 60 days postoperatively. The results of the current study showed complete healing of the induced defect in the absence of any signs of pain or discomfort. Radiographically, there was an increase in radiographic density in the first group at 60 days. There is continuing healing in the late stage of the bone segment with the surrounding area and a crossing callus with cortical irregularities, denoting a chronic periosteal reaction and a good healing process. In the second group, the defect was completely filled with cortical thickening, which appears denser, denoting a periosteal reaction. In conclusion, using hydroxyapatite nanogel with high viscosity as a bone substitute contributed to progressing bone tissue regeneration with good callus formation and giving perfect mechanical support to defective bone. ـــــــــــــــــــــــــــــــــــــــــ

This project evaluated the effects of nano magnesium oxide versus platelets rich fibrin on induced radial fracture bone healing. Eighteen males and non-pregnant females of adult local stray dogs, weighing 17.6±0.8 kg and aged 2.0±0.1 years, were used. These trials animals were randomly divided into three groups of equal numbers. In the first group, control group (C), a transverse radial fracture was induced then immobilized by external fixation as gypsum. In this group, the fracture line was not treated with any bioactive material. In the second group, platelets rich fibrin group (PRF), the fracture line was treated by adding platelets rich fibrin. In the third group, nano magnesium oxide (NMO), the fracture line was treated by adding a suspension of nano magnesium oxide. The radiographic results showed that the fractured bone healing was faster in the second group than in the first and third groups, while the third group was better than the first group. The concentration rates of serum calcium and alkaline phosphatase were increased in the weeks followed the surgical operation. Depending on the radiographic pictures and serial rates of alkaline phosphatase, the second PRF and the third NMO groups were the better-fractured bone healing than the first one. In conclusion, this study revealed that using each platelets rich fibrin and nano magnesium oxide enhanced and improved the healing of the induced radial fracture.
