From Silos To Systems: A Conceptual Framework For Workforce Aligned Oral Health Education, Meghan Bastin

2026 Scholarly Teaching Conference: Poster Session Papers

In the current U.S. educational system, becoming a dentist follows a few prescriptive pathways.  Learners typically complete an undergraduate degree before entering time-intensive doctoral training.  This results in only 3-4 years of direct professional education embedded within an eight -year process, while learners accumulate significant financial investment in their education.  With the average cost of graduate-level dental education alone exceeding $300,000 and new federal borrowing limits likely to further constrain access, there is an opportunity to explore alternative ways of structuring oral health education.

This poster presents a conceptual, system-level framework that explores a perspective in which oral health education …

Fluoride Justice, Brandon Ambrosino Phd, Mts, Ma

Journal of the American College of Dentists

Despite once being hailed as the second most effective medical intervention of the 20th century, fluoride has recently come under public attack. Taking aim at community water fluoridation, critics allege that fluoridation should be a matter of personal choice. This claim, however, overlooks both basic dental science and, more importantly, questions about our mutual obligations. This essay argues that providing people from all walks of life with access to a safe, low-cost, easy-to-use water source proven to improve oral health outcomes is an issue of community justice.
