Different views of dentists and general medical practitioners on dental care for patients with diabetes mellitus and coronary heart diseases: results of a questionnaire-based survey in a district of Germany

Abstract

The aim of this questionnaire-based study was to evaluate the views of dentists (Ds) and general medical practitioners (GPs) on different aspects of dental care for patients with diabetes mellitus (DM) or coronary heart disease (CHD). Reliable and comparable questionnaires for Ds and GPs, with 23 questions, were sent to 1,000 randomly selected Ds and 1,000 randomly selected GPs. Questions were asked about patients with DM or CHD regarding their dental care and potentially related issues (e.g. antibiotic prophylaxis). The responses received within 12weeks were evaluated and statistically analysed using chi-square and Mann-Whitney U tests (P<0.05). The response rate was 39% (n=391) for Ds and 18% (n=181) for GPs. Both groups stated that they used the medical history as well as patient interviews to assess patients. However, only 55% of Ds assumed correct identification of every at-risk patient compared with 100% of GPs (P<0.01). Furthermore, Ds speculated that they inform their patients more often about their at-risk status than do GPs (P<0.01). Neither Ds nor GPs appeared to be confident in their knowledge about adequate antibiotic prophylaxis. Interdisciplinary collaboration was considered insufficient, although Ds had a higher rate of regular collaboration (68% for Ds vs. 40% for GPs; P<0.01). Ds and GPs have differing views on dental care of patients with DM or CHD, and Ds showed more interest in this issue. These results might partially explain the insufficient collaboration between Ds and GPs.
