Radiographic Assessment of the effect of Demineralized Bone Matrix on Induction and Conduction of Osteogenesis in Repair of mandibular Bone Defect in cat

The main goals of treatment in the mandibular fractures include bone union¡ normal dental occlusion and immediate return to oral alimentation. In this study twelve adult cats were divided into two groups. A segmental defect of 5mm was created in one of the hemimandibles behind the 1st molar¡ the fractured site was fixed in both group using mini bone plate with 4 screws¡ then demineralized bone matrix (DBM) was used to fill the gap after fracture fixation in Group II. Radiography was done after creating defects on 0¡ 15¡ 30 and 60 days¡ from the radiological results the parameters of groups were compared with Lane and Sandhu scale system in terms of callus tissue¡ mineralization and remodeling ¡ the statistical data showed that group 2 differ significantly from the other group in terms of total scoring (p
