Abstract: Background　There is a two-way relationship between periodontal disease and diabetes.Although periodontal disease is a common complication of diabetes，it has not received much attention from patients and doctors.Objective　To investigate the periodontal status of patients with type 2 diabetes receiving contracted family doctor services in the Yuetan Community and analyze its influencing factors，in order to provide a theoretical basis for general practitioners to conduct oral health education for patients with type 2 diabetes.Methods　From March 1 to June 1 in 2018，200 patients with type 2 diabetes mellitus receiving contracted family doctor services in Yuetan Community Health Service Center and its subordinate stations were recruited by convenient sampling method for periodontal clinical examination and questionnaire survey.The survey included basic information，living habits，control situation of type 2 diabetes，and oral health care.Periodontal examination was performed using the community periodontal index（CPI） as a standard.Rank-sum test was used to analyze the highest and mean scores of CPI.Binary Logistic regression was used to analyze the influencing factors of excluded sextants.Results　There were 169 cases without excluded sextants，and the cases with highest CPI scores of 0，1，2，3，and 4 accounted for 3.5%，14.5%，46.5%，10.0%，and 10.0%，respectively.Univariate analysis of the highest and mean CPI scores of 169 patients showed that the highest CPI score of patients with duration of diabetes > 9 years was significantly higher than that of patients with duration of diabetes ≤9 years；the mean CPI score of patients never having the teeth cleaning was significantly higher than that of patients having the teeth cleaning every half a year to a year；the highest and mean CPI scores of patients who did not pay attention to oral health knowledge were both significantly higher than that of patients paying attention to oral health knowledge；the highest CPI score of patients who were not informed by the doctor about the relationship of diabetes and periodontal disease was significantly higher than that of patients who were informed；the highest CPI score of patients having bleeding gums during brushing was significantly higher than that of patients without gum bleeding（P<0.05）.There were 31 cases with excluded sextants and cases with 1，2，3，and 4 excluded sextants accounted for 5.5%，4.5%，3.0%，and 2.5%，respectively.The influencing factors of the presence of excluded sextants in patients with type 2 diabetes were age ≥ 65 years old〔OR=2.266，95%CI（1.011，5.079）〕，and duration of type 2 diabetes > 9 years〔OR=2.490，95%CI（1.056，5.889）〕（P<0.05）.Conclusion　Patients with type 2 diabetes who received contracted family doctor services in Yuetan Community have a poor periodontal condition，which is related to many factors.As a result，general practitioners need to pay more attention to patients' periodontal status and strengthen their oral health education.
