Abstract

This study will assess the effect of diabetes on the development of pulp and periodontal infection, singly or combined, in Wistar rats. It will be used 80 Wistar rats divided into 8 groups of 10 animals each: 1) normal rats, 2) normal rats with pulp disease, 3) normal rats with periodontal disease, 4) normal rats with pulp and periodontal diseases; 5) diabetic rats , 6) diabetic rats with pulp disease; 7) diabetic rats with periodontal disease, 8) diabetic rats with periodontal and pulp disease. Diabetes will be induced by application of alloxan and the disease development will be confirmed in the subsequent 24/48 hours by blood glucose evaluation. After confirmation of the diabetes induction, pulp and/or periodontal diseases will be induced according to the experimental group. At the end of 60 days the rats will be killed, the jaws removed and processed for laboratory evaluation in light microscopy. The tissue sections will be stained with HE and evaluated by pre-established criteria using scores to the observed microscopic events. The results will be analyzed using the Kruskall Wallis and Dunn's at a significance level of 5% (p <0.05).
