Most medical professionals do not discuss periodontal disease with diabetes patients

A survey of 128 medical healthcare professionals in Scotland found that most do not discuss the link between diabetes and periodontal disease with their patients, nor do they refer patients to dentists or inform dentists of a diabetes diagnosis. The study, conducted in 2021, included endocrinology consultants and registrars, general practitioners, diabetes specialist nurses, practice nurses and healthcare assistants across all 14 Scottish health boards. Researchers found that 92 percent of participants never or rarely advised patients with diabetes that their condition increases the risk of periodontal disease, and 93 percent never or rarely referred newly diagnosed patients to a dentist for oral assessment.

Knowledge gaps and barriers to communication

The primary obstacles to discussing the relationship are lack of knowledge and awareness. Seventy-three percent of participants indicated they were unaware of the link between diabetes and periodontal disease, and 92 percent were unfamiliar with guidance on managing this relationship. Time constraints and unclear referral pathways between medical and dental services also emerged as major barriers. Eighty-two percent reported insufficient time to discuss the topic, and 97 percent never or rarely contacted dentists to inform them of a patient's diabetes diagnosis. When asked about referring patients to dentists, 62 percent said they did not refer patients at all, while 34 percent would only indirectly signpost patients.

Potential solutions and future developments

Participants indicated support for interventions to improve communication. Forty-two percent said online learning resources for medical practitioners would be extremely helpful, while 67 percent identified an automated referral system alerting dentists to new diabetes diagnoses as the most useful tool. Since this study was completed in 2021, NICE updated its Type 2 diabetes guidance in 2022 with four new recommendations related to periodontitis, and in 2024 the Scottish Dental Clinical Effectiveness Programme published updated guidance on periodontal disease prevention and treatment that includes advice for medical practitioners. The researchers recommend future studies to assess whether these recent publications have changed medical professionals' behaviour and knowledge.
