Abstract
We evaluated the periodontal status of type 2 diabetes mellitus (DM) patients aged 38 to 76 years (n=66, mean age, 60.8±9.3 years) taking part in a 1-week education program. We assessed the correlation between periodontal and DM status and its complications, which include nephropathy, retinopathy, neuropathy, and cardiovascular disease. Periodontal assessment included present teeth, community periodontal index (CPI) , and loss of attachment (LOA) in all teeth, alveolar bone loss (ABL) in molars, percentage of sites with>20% ABL (20ABL) , percentage of sites with>50% ABL (50ABL) , and oral health score. Mandibular cortical shape was categorized into one of three groups based on panoramamic radiographs. Present teeth were 17.2±10.3, percentages of CPI codes 3 or 4 77.6±25.3%, ABL 31.3±14.2%, and 20ABL 90.1±18.3%. The number of teeth present, CPI code 4, LOA codes 2, 3 or 4, LOA codes 3 or 4, and 50ABL in stage 3 nephropathy were significantly worse than those in stages 1 and 2 nephropathy (p<0.01) . Present teeth and 20ABL with proliferative retinopathy were significantly worse than those without proliferative retinopathy (p<0.05, p<0.01) . 20 ABL with arteriosclerotic disease was significantly worse than that without arteriosclerotic disease (p<0.01) . Our results indicate that DM patients with type 2 diabetes had generalized advanced periodontal destruction. As nephropathy, retinopathy, and arteriosclerotic disease worsen, periodontitis may progress. Nihon Shishubyo Gakkai Kaishi (J Jpn Soc Periodontol) 48 : 165-173, 2006.
