Pathology of chronic ovine periodontitis

ABSTRACT: Periodontitis is an inflammatory process of infectious origin affecting the teeth and their supporting structures, causing significant economic losses reducing animal welfare. Bacteria in gingival biofilm are one main factors initiating lesions. act directly on tissues or indirectly through substances that cause tissue damage. Studies etiopathogenesis periodontitis Brazilian sheep herds scarce. The present study aimed to characterize histologically periodontal lesions culled from breed, Santa Inês. Periodontal lesions, such as pockets containing plant bacteria, replacement ligament by connective cells, superficial pustules, hydropic epithelial degeneration, epithelium hyperplasia, were observed. Submucosal changes characterized granulation tissue, edema, swelling endothelial predominantly perivascular lymphoplasmacytic infiltrate. In alveolar bone, osteoclastic resorption bone apposition This revealed subacute chronic inflammation, resorption, cortical ovine periodontitis. Thus, these findings can contribute evolution knowledge about and, possibly, development measures control disease.
