Twenty-four adult rabbits were divided into three study groups: control (C), diabetic (D) and diabetic associated to polytetrafluoroethylene (PTFE) membrane (D-PTFE). For diabetes induction the animals received one dose of monohydrated alloxan (90 mg/kg) by intravenous administration in the auricular or femoral vein. In group D-PTFE the membrane covered both the floor and the surface of the bone defect. In groups D and C, the bone defect was filled up with blood clot. The specimens were fixed in 10% formol and prepared for histomorphometric analysis. The results showed that the 90 mg/kg dose of monohydrate alloxan was sufficient to promote diabetes mellitus when administered in the auricular vein. Bone regeneration was slower in the diabetic group when compared with the control and diabetic-PTFE groups, but there was no significant statistical difference between the two experimental groups (D and D-PTFE). The oral and general clinical complications among the diabetics were weight loss, polyuria, polyphagia and severe chronic gingivitis.184-191engAlloxanBone regenerationDiabetes complicationsDiabetes mellitusalloxanbiomaterialpolitefanalysis of varianceanimalbone regenerationchemically induced disorderdisease modeldrug effectexperimental diabetes mellituspancreaspathophysiologyphysiologyrabbitrandomizationskullwound healingAnalysis of VarianceAnimalsBiocompatible MaterialsBone RegenerationDiabetes Mellitus, ExperimentalDisease Models, AnimalPancreasParietal BonePolytetrafluoroethyleneRabbitsRandom AllocationSkullWound HealingArtigo10.1590/S1806-83242008000200015S1806-83242008000200015Acesso aberto2-s2.0-482491381492-s2.0-48249138149.pdf1274225455678400
