摘要

Background

Diabetes Mellitus (DM) is a global metabolic disorder affecting 537 million adults. Periodontitis stands as its sixth major complication and shares a bidirectional relationship with diabetes, whereby each condition exacerbates the other. This interaction worsens glycaemic control and oral health, increasing the risk of further complications. Despite the serious implications for health, patient awareness remains low. Interventions within health education show promise, yet face challenges with regards to compliance and accessibility. Evidence-based strategies are required to improve patient outcomes.

Objective

To synthesise the available evidence on health education for patients with diabetic periodontitis, in order to provide a high-quality evidence base to inform clinical practice.

Methods

PubMed, the Cochrane Library, and other databases were searched, and guidelines, expert consensus statements, systematic reviews, and randomised controlled trials were included. The search timeframe was from the inception of each database to April 22, 2026. The quality of the literature was independently assessed by two researchers, utilising the AGREE II and JBI tools for quality appraisal. Evidence was graded in accordance with the JBI Levels of Evidence and Grades of Recommendation (2014).

Results

A total of 27 articles were included, comprising 2 guidelines, 3 expert consensus statements, 2 systematic reviews, and 20 randomised controlled trials. From these, 32 practice-oriented evidence statements were summarised under seven key themes: Disease Education, oral care, dietary guidance, exercise, follow-up, social support, and psychological care.

Conclusion

This study has summarised the core evidence for health education in patients with co-existing diabetes and periodontitis, providing a foundation for clinical practice. However, the research is subject to several limitations, including sample size constraints, cultural variations, and the limited availability of evidence on long-term effects. Future work should aim to expand the scale of research, optimise personalised interventions, and strengthen multidisciplinary collaboration to improve patient management and quality of life. Health education is vital to the integrated management of this patient group; clinical evidence should be applied flexibly, considering individual needs, to achieve optimal therapeutic outcomes.
