• bacterial biofilm
• osteomyelitis

The purpose of this paper was to analyze specimens of autogenous bone block grafts exposed to the oral cavity after ridge reconstructions. Specimens of chronic suppurative osteomyelitis (CSO) of the jaws were used as comparison for bacterial colonization pattern. For this, 5 specimens of infected autogenous bone grafts were used and 10 specimens of CSO embedded in paraffin were stained with Brown and Brenn technique and analyzed under light microscopy. The results showed a similar colonization pattern in both situations, with the establishment of bacterial biofilm and the predominance of Gram-positive bacteria. The conclusion was that the similarity in bacterial distribution and colonization between autogenous bone grafts and CSO stresses the necessity of more invasive procedures for the treatment of the autogenous bone grafts early exposed to the oral cavity.
