Resumo

ObjectivesStudies have documented the anti-inflammatory effects of spices, which may be related to treatment of chronic diseases. The purpose of this study was to evaluate the influence of curcumin and piperine and their association on experimental periodontal repair in rats.Materials and methodsPeriodontitis was induced via the installation of a ligature around the first molar. After 15days, the ligatures were removed, and the rats were separated into groups (12 animals per group): (i) curcumin, (ii) piperine, (iii) curcumin+piperine, (iv) corn oil vehicle, and (v) control group (animals had ligature-induced periodontitis but were not treated). The compounds were administered daily, for 15days by oral gavage. Animals were euthanized at 5 and 15days, and hemimaxillae and gingival tissues were harvested. Bone repair was assessed by mu CT (microcomputer tomography). Histological sections were stained with hematoxylin/eosin (H/E) for the assessment of cellular infiltrate or picrosirius red for quantification of collagen content, and subjected to immunohistochemistry for detecting NF-?B. Gingival tissues were used to evaluate levels of TGF-beta and IL-10 (ELISA).ResultsCurcumin and piperine increased the TGF-beta level, significantly improved the collagen repair, and decreased the cellularity and activation of NF-?B in the periodontal tissues, but only curcumin caused a significant increase in early bone repair.ConclusionCurcumin and piperine promoted a substantive effect on tissue repair; however, there was not synergistic effect of compounds administered in combination.Clinical relevanceCurcumin and piperine stimulates the tissue repair and may be potential candidates for the treatment of periodontal disease.
