【摘要】 目的 了解内分泌科医生和T2DM患者对糖尿病和牙周炎关系的认知情况。方法 以个人访谈和问卷的形式分别调查两组人群对糖尿病和牙周炎关系的认知情况和建议，以数据和访谈记录支持分析结果。结果 T2DM患者对口腔保健知识认知正确率波动在1.5～40.2%，牙周炎关注组与未关注组在“牙周炎可能影响血糖”、“改善牙周炎对预防糖尿病有效”的认知程度差异有统计学意义(P<0.05)。85.9%的患者表示在被明确告知糖尿病和牙周炎关系后会主动关注该问题。内分泌科医生牙周炎关注率、询问率分别为13%和3.8%。结论 T2DM患者对糖尿病和牙周炎关系普遍缺乏认知，内分泌科医生也对此关注不足，医患双方应提高对糖尿病和牙周炎并存危害的认知，改进诊治策略与流程，以提高患者生活质量。

　　【Abstract】 Objective To find out how well the endocrinology doctors and T2DM patients cognize the correlation between T2DM and periodontitis. Methods Personal interviews and questionnaires were taken as methods of the survey of both T2DM patients and endocrinology doctors on their cognition on correlation between T2DM and periodontitis. The interview records and data were served as the support of analysis. Results The rate of correct oral health knowledge was 1.5%～40.2% in T2DM patients. The knowledge level that ‘periodontitis may influence blood glucose’ and ‘to control periodontitis is an effective way to prevent T2DM’ is higher in patients of the concerning periodontitis group compared with those of the periodontitis unconcerned group (P<0.05). The 89.3% of the patients would pay more attention to their oral hygiene problems when informed the correlation between these two diseases. In endocrinology doctors, the rate of pay-attention to their patients’ periodontitis was 13%, and the asking rate about this illness only accounted for 3.8%. Conclusions Most T2DM patients and endocrinology doctors lack knowledge of the correlation between these two diseases. For both patients and doctors, it is necessary to enhance the knowledge of danger in coexistence of these two diseases, thereby improving the treatment strategy and the life quality of the patients.
