Objective:
This study was performed to explore the impact of telmisartan on experimental periodontitis in mice, in terms of alveolar bone destruction, by using micro-computed tomography analysis.
Materials And Methods:
Male BALB/c mice were divided into four groups of 7 to 9 mice each: control (C) group; experimental periodontitis (E) group; experimental periodontitis-plus-telmisartan 5 mg/kg (ET5) group; and experimental periodontitis-plus-telmisartan 10 mg/kg (ET10) group. The mice in Group C were not subjected to experimental periodontitis. The other mice from Groups E, ET5 and ET10 were exposed to periodontitis. Periodontitis was induced by inoculation with Porphyromonas gingivalis.
Results:
Telmisartan significantly suppressed both the reduction in alveolar bone height and increase of root exposure caused by P. gingivalis infection. When mice were treated with telmisartan, the decrease in the bone volume fraction induced by the infection was notably recovered. In addition, telmisartan reversed P. gingivalis-induced alterations in the microstructural parameters of trabecular bone, except trabecular thickness.No significant difference was evident between Groups ET5 and ET10 in both the extent of alveolar bone loss and microstructural parameters assessed, except bone volume fraction and trabecular number.
Conclusion:
Telmisartan may have potential benefits as a host modulation agent for the therapy of periodontitis.
