Summary

The bone balance is mediated by an immunoendocrine regulation, this being a complex process. A number of pharmacotherapies are used among the actions taken to maintain the density and structure of the skeleton. Several studies have shown that both Alendronate (AL) and Vitamin E (E) contribute to the inhibition of bone resorption. Objective: To study the effect of combined administration of (LA) subcutaneously and (E) was administered three times per week also subcutaneously with a dosage of 20 mg / kg body weight. The pharmaceutical formulation was 0.5 mg / kg body weight for AL and 20 mg / kg vitamin E. The effect was evaluated in male Wistar rats (n = 108), 90 ± 20 g, divided into 4 groups. Extraction of the first lower molars was performed. The drug was injected subcutaneously at time 0, 7, 15 and 30 days post-surgery. The images of the jaws were acquired by radiovisiography, at each experimental time and were analyzed with Image ProPlus Software version 4.1 of Media Cibernetics. Statistical studies: non-parametric: Kruskal-Wallis test Group C (which recorded the lowest mean intensity) was significantly different from the E and AE groups (p <0.001), but not from the group that used only Al (P = 0.070, p> 0.05). The Al, E and combined Al-E groups did not differ significantly from each other (p> 0.05 in all cases). The data evaluated serve to show a favorable trend in relation to the beneficial effect of the combination of AL and vitamin E.
