Abstract

Oral health is far more than just a bright smile — it is a vital indicator and influencer of overall health and wellness. This lecture explores the dynamic relationship between the mouth and the body, revealing how oral conditions can both reflect and contribute to systemic diseases. Mounting evidence shows that poor oral health is closely linked to cardiovascular disease, diabetes, respiratory infections, and even adverse pregnancy outcomes. Periodontal disease, in particular, has been associated with heightened risks of heart disease and stroke due to the inflammatory and microbial pathways that connect oral and systemic health. Likewise, individuals with diabetes often face greater challenges in managing gum disease, which in turn can worsen glycemic control, creating a two-way relationship.

Through an exploration of current research and clinical insights, this session will illuminate the biological mechanisms that bridge oral and overall health, emphasizing the crucial role dental hygienists play in prevention, early detection, and patient education. By understanding the mouth-body connection, participants will be better equipped to promote comprehensive health — one patient at a time.
