Integrating Periodontal Care Into Diabetes Management: A Narrative Perspective for Bangladesh With Global Relevance.

Background: Type 2 Diabetes Mellitus (T2DM) and periodontal disease are highly prevalent chronic conditions that share a complex, bidirectional relationship. While extensive research confirms their mutual influence-where poor glycemic control exacerbates periodontal destruction and chronic periodontal inflammation impairs insulin sensitivity-this critical connection remains largely unaddressed in both clinical guidelines and public health policy, particularly in low- and middle-income countries (LMICs) like Bangladesh. Objective: This narrative, evidence-informed perspective article aims to explore the epidemiological, clinical, and systemic interconnections between periodontal disease and T2DM, with a specific focus on Bangladesh. It underscores the urgent importance of integrating oral health into diabetes care frameworks and advocates for strategic health policy reforms grounded in recent research and global best practices. Findings: Globally, over 500 million people live with diabetes, and nearly half of the adult population suffers from some form of periodontal disease. In Bangladesh, a recent epidemiological study indicated that T2DM prevalence exceeds 10%, with hospital-based studies indicating that over 80% of diabetic patients also have periodontal disease. The bidirectional link is well-established: periodontitis exacerbates insulin resistance and increases HbA1c levels, while poorly controlled diabetes accelerates periodontal tissue destruction. This article identifies systemic barriers, policy gaps, and a lack of public awareness as key impediments to integrated care. It proposes evidence-based strategies, including enhanced interprofessional collaboration, public health campaigns, leveraging digital health, and developing culturally sensitive policies. Conclusion: Integrating periodontal care into comprehensive diabetes management is not merely a clinical recommendation but a public health imperative for Bangladesh, with significant global relevance. Addressing this bidirectional relationship through collaborative healthcare models and targeted policy reforms can improve glycemic control, reduce diabetes complications, and enhance the overall quality of life for millions, contributing to more sustainable and holistic healthcare systems.
