Chronic Periodontitis is an inflammatory disease of the supporting tissues of the teeth caused by specific microorganisms or groups of specific microorganisms, leading to progressive destruction of the attachment apparatus of the teeth including periodontal ligament, cementum and alveolar bone with periodontal pocket formation, and recession of the gingival tissue(1) . The clinical feature that characterizes periodontitis from gingivitis is the presence of clinically apparent attachment loss. This loss mainly is associated with changes in the density and height of subjacent alveolar bone (1). Severe generalized periodontitis affects 5–15% of any population worldwide and is a major cause of teeth loss after dental caries (2).
Chronic Periodontitis also known as adult periodontitis or chronic adult periodontitis, and is the most prevalent form of periodontitis. It is considered to be a slowly progressing disease occurs as a result of local accumulation of bacterial plaque. However, the host response to plaque accumulation can be modified by systemic and environmental factors, like diabetes, smoking, and stress, causing more severe disease progression. Although chronic periodontitis is most frequently observed in adults, it can also occur in children
It affects 0.5-1% of the world population and occurs mostly during the 4th and 5th decades of life. It affects women about three times more than men (72). The basic features of this disorder are bilateral and symmetric chronic inflammation of the synovium (synovitis). Patients with RA may complain of systemic disorders such as weakness, vague musculoskeletal pain, fatigue, and loss of appetite. Increased risk of premature mortality and that mortality depend on the severity of the course of the disease
