Oral Health Knowledge, Attitudes, Behaviour and Oral Health Status of Chinese Diabetic Patients Aged 55 to 74 Years.

OBJECTIVE: To understand the oral health knowledge, attitude, behaviour and oral health status of Chinese diabetic patients so as to facilitate the development of oral health education programmes for diabetic patients in China.
METHOD: A face-to-face questionnaire was conducted for 1,024 diabetic patients and 8,030 non-diabetic people aged 55 to 74 years old in order to understand their oral health knowledge, attitudes, and behaviour. Oral health examination was implemented including caries, gingival bleeding, dental calculus, periodontal attachment loss, etc. according to the Oral Health Surveys Basic Methods 5th Edition.
RESULTS: Compared with non-diabetic patients, those with diabetes had more oral health knowledge and more positive attitudes. The proportion of people who formed toothbrushing habits was higher in diabetic patients, but that of regular scaling and flossing is as low as that in non-diabetic people. The detection rate of deep periodontal pockets in diabetic patients was higher than that in non-patients, while the caries situation was better than that in non-patients.
CONCLUSION: This study has shown that the oral health knowledge, attitude, behaviour and oral health status of the 55 to 64-year-old diabetic population are not optimistic. There is a great need for a systematic oral health education programme in China. The contradiction between a large number of diabetes patients and limited health resources requires us to give priority to the improvement of oral health behaviours, such as educating patients to develop toothbrushing and flossing habits.
