目的:调查某部离退休老干部糖尿病患者牙周炎患病情况。方法:选择某部离退休老干部体检中确诊的糖尿病138例作为观察组,从同批体检的无糖尿病老干部中随机选择138例作为对照组。比较两组菌斑指数(PLI)、出血指数(BI)、探诊深度(PD)、附着丧失(AL)等牙周炎临床指标,并分析观察组口服葡萄糖耐量试验(OGTT)2 h血糖水平与牙周炎各临床指标间的关系。结果:观察组PLI、BI、PD及AL值均显著或非常显著高于对照组(P<0.05,P<0.01),其牙周炎总患病率及中、重度牙周炎患病率,均非常显著高于对照组(P<0.01)。观察组中,OGTT 2 h血糖水平13.1~17.9 mmol/L亚组牙周炎各指标值与≤13.0 mmol/L亚组比较,差异均不显著(P>0.05);而血糖水平≥18.0 mmol/L亚组牙周炎各指标值除缺失牙数外,则显著或非常显著高于≤13.0 mmol/L亚组(P<0.05,P<0.01)。结论:离退休老干部糖尿病患者的牙周炎患病率及严重程度显著高于无糖尿病人群,其口腔卫生教育及血糖控制亟待加强。 Objective: To investigate the prevalence of periodontitis among diabetic patients in a retired cadre. Methods: A total of 138 diabetic patients diagnosed in the retired cadres’ medical examination were selected as the observation group, and 138 control subjects were randomly selected from the non-diabetic veteran cadres. The clinical indexes of periodontitis such as plaque index (PLI), hemorrhage index (BI), probing depth (PD) and attachment loss (AL) were compared. The blood glucose level in oral glucose tolerance test (OGTT) And the relationship between the clinical indicators of periodontitis. Results: The PLI, BI, PD and AL in the observation group were significantly or very significantly higher than those in the control group (P <0.05, P <0.01). The total prevalence of periodontitis and the prevalence of moderate and severe periodontitis, Were significantly higher than the control group (P <0.01). In the observation group, there was no significant difference between the two groups (P> 0.05); The blood glucose level was higher than or equal to 18.0 mmol / L The indexes of periodontitis in L group were significantly or very significantly higher than those of ≤13.0 mmol / L subgroup except the number of missing teeth (P <0.05, P <0.01). Conclusion: The prevalence and severity of periodontitis in retired veteran diabetic patients are significantly higher than those in non-diabetic patients, and oral health education and blood glucose control need to be strengthened.
