It has been documented that diabetes is one of the risk factors in periodontal disease. With the high prevalence of diabetes in Singapore adults, there is no available data on the oral health behaviour of diabetics in the local context. Objectives: The aim of the study is to find out the oral health attitudes and practices of adult diabetics receiving medical treatment at a diabetic centre. Methods: A questionnaire survey together with clinical and laboratory parameters were conducted to profile the diabetic patients from a hospital-based Diabetic centre as part of a larger scale study. 112 adult diabetics age 21-65 responded to questionnaires relating to oral self-care, attitudes and practices (15 items) and diabetic conditions (12 items). Results: While the majority of the patients are compliant in their diabetic control, findings reveal that more than two thirds of diabetics, do not visit a dentist annually; a similar proportion do not know nor were they informed that they were at high risk for periodontal disease (p<0.05). Although most patients claim to be brushing regularly (99.1%), interdental cleaning was not practised by the marginal majority (50.5%). Only 9.3% of participants has acceptable level of knowledge on periodontal health (p<0.001) and ability to detect gum disease was also low at 25%. Conclusion: Preliminary study of diabetics attending treatment at a Diabetic centre showed that the majority of diabetics have low periodontal health awareness, infrequent dental visits and interdental cleaning behaviour. The findings highlight a need to promote oral health as part of the overall component of medical health care for patients with diabetes. This study was supported by NUS grant 222-000-017-112.
