Abstract

Objectives: To evaluate the effects of green tea intake and zoledronic acid intravenous therapy on teeth socket repair. Design: Sixty male albinus Wistar rats were divided into 4 groups: C-Control, intravenous (IV) 0.9% saline solution (SS), GT-1% green tea in drinking water and IV SS, BP-IV zoledronic acid (BP), and BP + GT-IV BP and 1% green tea. 0.035 mg/kg of BP was administered every two weeks. After ten weeks, right upper molars were extracted and the green tea started to be offered for GT and BP + GT. After 7, 14, and 28 days the animals were euthanized. Results: Histopathology analysis revealed lack of socket repair in BP and BP + GT groups, which presented significant increased number of polimorphonuclear leukocytes at day 28, in comparison with C (p < 0.05). No significant differences were detected between C and the experimental groups at the same period (p < 0.05) when considering mononuclear leukocytes. Immunolabeling revealed that the association of BP and GT caused a slight disturbance in OPG/RANKL system and retarded Runx-2 labeling. Although strong TRAP labeling was observed, most of the positive cells in BP and BP + GT groups were not located on bone surface. Conclusions: Socket healing of rats treated with BP and regular drinking green tea presented no relevant differences in comparison to those treated with BP alone. (C) 2016 Elsevier Ltd.
