Abstract

ESCUDERO, Cristina; VIRGA, Carolina; AGUZZI, Alejandra  and  DE-LEONARDI, Adriana. Histomorphometric Analysis of the Association of Olive Oil and Bisphosphonates on Peri-Implant Bone Remodeling. Int. J. Odontostomat. [online]. 2017, vol.11, n.4, pp.481-485. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2017000400481.

Bisphosphonates are potent inhibitors of bone resorption. Olive oil (O) has anti-inflammatory and anti-oxidant properties. To study the effect of combined treatment with alendronate (AL) and pamidronate (PA) subcutaneously or orally, and on tissue regeneration of newly formed bone cavities, we divided 54 male Wistar rats into 6 groups. Control group (C) received saline subcutaneously. Group (AL) received 0.5 mg of AL / kg body weight subcutaneously. Group (PA) received the same as the previous group. (O) was treated with olive oil diet, 50 g / kg of food. Group (ALO) received combined treatment with AL and O. Group (PAO) received the same treatment. The animals were euthanized for sampling at 15, 30, 60 and 90 days. For histopathology sections were stained with HE and observed these with light microscopy. Statistical studies were performed by analysis of variance. Fifteen days osteocytes areas of the PA group were significantly different only for the AL group. As the density increased trabecular bone tissue was observed in all groups. O qualitatively improved the structure of trabecular and cortical bone mineralization while preserving the size and structure of the mineral crystals. This suggests that O represents a promising therapeutic option for prevention and treatment of bone diseases.
