Oral health care among patients with diabetes in Australia : a snapshot

Background: Diabetes increases the risk of periodontal disease, which in turn negatively impact on diabetes control and complications. Therefore, awareness about the diabetes-oral health link and dental problems is important for people with diabetes. This study aimed to assess self-reported oral health status and knowledge of people living with diabetes. Methods: A survey was conducted among patients who attended four public diabetes clinics in Sydney, Australia. The questionnaire included 10 knowledge items and a validated Oral Health Impact Profile (OHIP-14) scale. A convenience sample of 200 patients were recruited. The data were analysed using SPSS software with descriptive and Pearson’s Chi-Squared tests reported. Results: The mean age of participants was 62.4(13.5) years. More than half were males (54.5%), born overseas (64%), not working (73%) and had type 2 diabetes (88%). More than half (55.1%) of the patients reported having one or more dental problems and this was negatively associated with their oral health-related quality of life (p < 0.001). The most common d dry mouth. Only 46.2% of the participants had adequate oral health knowledge (> the mean correct score 5.2 (2.6). The main areas with poor knowledge were around the impact of gum disease on blood glucose levels (29.6%), effects of dry mouth on tooth decay (33.8%) and the link between diabetes and teeth and gums (44.5%). Only 13% of the patients reported receiving oral health information from diabetes care providers (diabetes educator, general practitioner/diabetes specialist and dietitian/nutritionist). Receiving oral health information was found to be significantly associated with higher oral health knowledge scores (p < 0.05). Conclusions: Considering that a majority of patients with diabetes have dental problems and inadequate oral health knowledge, diabetes care providers should take the opportunity to educate patients about oral health risks.
