Microscopic analysis.

<p>(A) Normal periodontium and (B) periodontium from a rat presenting with periodontitis (treated with saline) showing alveolar bone and cementumresorption and inflammatory cell infiltration. (C) Reduced inflammation and alveolar bone loss in the periodontium of rats treated with Atorvastatin (10 mg/kg) for 10 days. Sections were stained with H&E. Microscopic original magnification at 40×. Scale bars = 100 µm. G = gingiva; PL = Periodontal ligament; D = dentin; AB = alveolar bone; C = Cementum; a = increased bone loss in AB; b = resorption of cementum; c = inflammatory process in PL and intense destruction of collagen fibers in the PL; e = decreased inflammation process in PL anddiscrete destruction ofcollagen fibers in PL; f = decreasedbone loss in AB.
