RESUMO

The purpose of this study was to evaluate, in healthy animals, the role of salmon calcitonin in the bone healing process of circumscribed bone defects, surgica1ly created, in the twenty-four (24) young adults rabbits femur. Twelve (12) animals were randomized to be the control and test groups (salmon calcitonin - 2 IU/kg during 21 days). The rabbits were sacrificed 7, 14, 21 and 28 days after the surgical procedures. The radiolucids areas of the bone defects was measured, in mm2, by Auto-Cad software. The results showed statistical differences (p<0,05) at 14 and 21 days, favoring the test group. At 7-day, the bone defects of the test group showed more bone regeneration. Nevertheless, at 14 and 21-days, the results was similar among two groups, with the new bone more compact in the test group than control group at 28 days. Thus, this study did demonstrate the positive role of salmon calcitonin in the bone healing process of circumscribed bone defects in healthy rabbits, considering the radioagraphic and histological analysis
