Periodontal bone response under the influence of Cr(VI)

Abstract

Object: The object of this study was to analyze alveolar bone response under the influence chromium (VI). Methods: 20 male albino rats that weighed 300–325 g were evaluated for histologically and scanning electron microscopy of Ca, P, K, Cr. Results: The interaction between normal periodontal tissues and 60 days experiment was strongly significant. Destruction may progress until tooth support becomes inadequate and more complex patterns of bone loss develop. Despite the deep extension of inflammation it may absent in the alveolar bone , which may also lack any sign of osteoclastic activity histologically. The lowest levels of P and K were observed in 60 days of experiment (P < 0.01). 60 days level may affect the mineral status of bone and chronic incoming of chromium. Conclusion: Chronic chrome (IV) intoxication characterized by heavy chronic destruction of collagen, apoptotic, bone changes, and epithelial hyperplasia. Untreated chronic chrome (IV) intoxication slowly progresses to chronic periodontitis in which there destruction of deep tissues. At these 60 days, progressive resorption of alveolar bone occurs and the tooth ultimately gets detached.
