Efficiency of periodontal therapy for management of CVS diseases in patient with chronic periodontitis

To evaluate the effectiveness of periodontal prophylaxis/ treatment in patients with chronic periodontitis already suffering from cardiovascular system (CVS) diseases. 500 Subjects with periodontal diseases (PD) were grouped according to treatment (dental prophylaxis, intensive treatment, and PD without treatment). The Incidence Rates (IRs) of CVS diseases during the 1-year follow-up period were compared among groups. Cox regression analysis adjusted for age, sex, socioeconomic status, residential urbanicity, and comorbidities was used to evaluate the effect of PD treatment on the incidence of CVS diseases. The IR of CVS diseases among subjects without PD was 0.19%/year. Among those with PD, the IR of CVS diseases was lowest in the dental prophylaxis group (0.11%/year), followed by the intensive treatment (0.28%/year) and PD without treatment (0.31%/year; P
