ABSTRACTObjective: The aim of this study was to evaluate the effect of the daily oral administration of vitamin D, calcium, fluoride and vitamin C as dietary supplementation on bone healing in bisphosphonate treated experimental animals (rabbits).Material and methods: Eight young male rabbits divided into two groups after induction of open ulnar osteotomy, both groups received weekly 1 mg/ kg BW of alendronic acid (alendron) orally starting 6 days before osteotomy for five weeks, the experimental group received daily dose of vitamin D, calcium, fluoride and vitamin C as dietary supplementation from the second post operative day for four weeks. The control group received ordinary diet. At the end of the fifth week the animals' sacrificed and the specimens taken for radiological and computerized tomography (CT) scan densimetry and histomorphometric evaluation carried out for the callus at site of osteotomy. Results: All ulnar bone osteotomies in both groups united at the end of the fifth week macroscopically and radiologically. The callus density was measured in site of osteotomy by CT scan densimetry, its mean in the experimental group was 681 ± 219 and in the control group was 492 ± 233. The difference between the experimental and control group was significant, (P value
