Independent from hyperlipidemia, hypertension, diabetes mellitus, smoking, a classical risk factor for arteriosclerosis, it has been shown that various types of chronic inflammationmay be involved in the development of arteriosclerosis. As a chronic inflammation, theprevalence rate of periodontal disease is reported to be about 80% at the age of 30 to 50years, and about ₉0% at the age of 60ʼs. In this study, cardio ankle vascular index (CAVI),a vascular function test, was measured as an indicator of arteriosclerosis before and aftertreatment of periodontal disease. As a result, it was revealed that CAVI statistically significantly decreased by treatment of periodontal disease. Further studies are needed in th
