Abstract

Objective: This study aimed to evaluate the role of fresh autogenous cement and dentine as bone graft to repair bone defects in dogs.

Study design: 3 adult dogs were used as subjects, 2 bony defect were created on the buccal surface of the mandible in each dog, one of them was grafted with fresh autogenous cement and dentine (test group) and the other was served as control, Samples were then biopsied in 4, 8, and 12 weeks.

Results: After 4 weeks there was new cell lining attached to bone graft pieces in test group,after 8 weeksbone formation surrounding the bone graft pieces was observed.On the other hand less bone formative activity was evident in control group. After 12 weekswe observed that most bone graft pieces underwent resorption, and the volume of new bone increased and became interconnected with the surrounding bone, while only fibrosis and small area of new formed bone could be observed in the control group.

Conclusions: The use of fresh autologous cement and dentine as bone graft led to active bone formationwith excellent quality.
