Knowledge about the association between periodontal diseases and diabetes mellitus: contrasting dentists and physicians.
BACKGROUND
There is a strong body of evidence that supports the relationship between periodontal diseases and diabetes mellitus (DM). Many patients are unaware of the effects of diabetes on oral health. Whether health care providers are applying the information about the link between DM and periodontal diseases in their practices depends on the levels of their knowledge of such valuable information. Therefore, the aims of this study are to evaluate the knowledge of dental and medical practitioners concerning the effects of diabetes on periodontal health and to find out if the practitioners are aware of the bidirectional relationship between periodontal diseases and DM.


METHODS
This was a cross-sectional survey of randomly selected general practitioners practicing in Kuwait. Participants were asked about specific periodontal complications that they believed patients diagnosed with diabetes were more susceptible to, and their awareness of the bidirectional relationship between diabetes and periodontal diseases was evaluated.


RESULTS
A total of 510 general practitioners (232 physicians and 278 dentists) participated in the study. There were no significant differences between the two groups regarding mean ages, sex distributions, and years in practice. Only 50% of all study participants believed that patients with diabetes were more susceptible to tooth loss because of periodontal diseases than were individuals without diabetes. Dentists were significantly more aware of gingival bleeding, tooth mobility, and alveolar bone resorption than were physicians. Factors significantly associated with having knowledge about the effects of diabetes on periodontal health in logistic regression analyses were older age, female sex, and the dental profession.


CONCLUSIONS
The knowledge about the association between periodontal diseases and DM should be increased among dental and medical practitioners to effectively prevent, manage, and control diabetes and periodontal diseases.
