Background: &zwj;Considering the fact that research on the marine products and creatures, in particular coral, has started just in the past decade and more attentions are focused on the benefits of this material, it has been decided to utilize the coral native to Persian Gulf as oral powder to heal tibia bone defect in rabbit. Methods: In this experimental study 18 New Zealander rabbits weighing 2.5-3 kg were categorized randomly in 3 groups (control, oral calcium powder and oral coral powder group) of 6 rabbits. For inducing the defect, the first 3rd part of tibial bone was blunt dissected. A whole with the depth of 0.6-0.8 mm and diameter of 4 mm was produced in all 3 groups in the same style. The Calcium group was treated daily with 1150 mg calcium powder, coral group received 1220 mg of coral powder and control group were kept under standard condition. Course of treatment was 2 months and on days 0,10,20,30,40,50,63 the animals were evaluated for healing criteria such as filling the defects, density, external callus formation and intercortical callus. Results: Radiologic parameters indicates that filling defect, density, external and inter cortical callus and absorption for animals receiving coral is better than that of control and calcium group (P<0/05). Conclusion: In conclusion, by oral administration of Persian Gulf coral powder results increasing the rate of bone formation. Finally for human use, these results must be evaluated more in clinical studies.

Keywords: Persian Gulf coral, bone healing, inter cortical callus, radiography
