Purpose:

To evaluate the knowledge of diabetic patients towards the connection between diabetes mellitus (DM) and oral diseases. Oral status was also assessed in order to evaluate the correlation among patients’ perception and their oral health.

Material and Methods:

A sample of 132 diabetic subjects answered a questionnaire containing 12 questions addressing their knowledge, attitudes and practices related to oral health. Oral examination accessed the presence of cavity carious lesions, residual roots, dental biofilm, calculus, gingivitis, tooth mobility and gingival recession.

Results:

Fifty-four percent of the sample had never been instructed by their health professionals that DM could cause oral diseases. However, 66% presumed being more vulnerable to develop oral illnesses and 57.5% answered that they assumed having no oral disturbances at that moment. In contrast, intraoral clinical examination showed that 99% presented at least one oral injury such as caries lesions, plaque/calculus, gingival inflammation, tooth mobility, residual root and xerostomia.

Conclusions:

Health care professionals usually neglect oral status in diabetic patients. Above all, there is a huge gap between patients’ perceptions towards oral health and their real oral status. This study highlights the need of developing new models of prevention that properly address the important clinical relation between oral diseases and DM.(AU)
