RESUMO

The purpose of this research was to histologicalIy evaluate the healing process in bone defects surgically created in calvaria of rabbits, with or without bone grafts under the action of eletrotherapy or not. It were utilized 18 rabbits with 2 perfurations in each calvaria. In the right parietal bone perforation the fragment removed was immediately grafted in its place. lu the left parietal bone the fragment was thrown away. The animais in the treated group received 1 hour of eletrotherapy dayly, during 21 days. The animals in the control group were submitted to the same stress conditions, but the stimulator was turned off. The sacrifice periods were 4, 7 and 15 weeks, with 6 sacrificed animais in each group. The analysis of the specimens under optical microscopy revealed bone formation in all animals. In the animals with the bone grafted there was a more noticeable healing when compared to the animais in the control group. With regard the electrotherapy it seems to affect the bone healing mildly
