Aim: The aim of this study was to evaluate the relationship between pulpal and/or periodontal disease and serum creatinine levels in a rat model of diabetes mellitus. Methods: Eighty male rats (Rattus norvegicus albinus, Wistar) were divided into the following 8 groups compris-ing 10 animals each: normal (G1), with pulpal disease (G2), with periodontal disease (G3), with both pulpal and periodontal disease (G4), diabetic (G5), diabetic with pulpal disease (G6), diabetic with periodontal disease (G7), and diabetic with both pulpal and periodontal disease (G8). Diabetes was induced by injecting streptozotocin, pul-pal disease were induced by exposing pulpal tissue to the oral environment, and periodontal disease was induced by periodontal ligature. After 30 days, blood was collected by cardiac puncture and the animals were killed. The maxillae were processed for histopathology. Serum creatinine levels were measured by the enzymatic method. The total assessed values were statistically analyzed by analysis of variance and Tukey’s test (p < 0.05). Results: Serum creatinine levels were significantly higher in diabetic rats than that in all normoglycemic rats (p < 0.05). The presence of pulpal and periodontal disease increased the serum creatinine levels in normoglycemic and diabetic rats, but there was no statistical difference between the groups (p > 0.05). Conclusions: We found that the serum creatinine level was higher in diabetic rats and may be related to the pres-ence of oral infections. Clinical significance: Changes in serum creatinine level may be related to the presence of oral infections and diabetes.

The objectives this research are: (a) describing positive interactions established between teacher and student, considering clinical group to behavior problems and non-clinical one; (b) describing behavior repertoire (social skills and behavior problems) of children with and without clinical classification to behavior problems, according to TRF, teacher version. The participants this study were 16 female teachers who indicated and evaluated 32 students - 16 of them presented behavior problems (with BP – clinical group), whereas the other 16 did not (without BP – non clinical group). Students aged 6 years were enrolled in the first year of elementary school. Data collection was conducted through the application of three instruments: TRF, RE-HSE-Pr and QRSH-Pr, as an interview with teachers. Data were categorized and analyzed to compare the clinical and nonclinical groups (Mann-Whitney Test). Overall, this research found that female teachers exert different practices among students who have behavior problems that do not show, being more skilled in the interactions with children without behavior problems and more agressive to those with behavioral problems. Implications for interventions and public policies are discussed.
