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 …

Endodontic Access Through Zirconia Crowns: A Comparative Evaluation Of 3d Guided Versus Free-Handed Techniques, Maryam Alrughaib

Theses and Dissertations

Objective:

Accessing canals through full-coverage zirconia crowns is challenging and may increase the risk of misdirection, excessive dentin removal, and prolonged chair time. Guided endodontic access has been proposed to improve efficiency and precision. This study compared the accuracy and time efficiency of guided versus free-hand endodontic access through zirconia restorations. The hypothesis was that guided access would enhance canal localization precision and significantly reduce access time.

Methods:

Thirty-two extracted maxillary premolars were restored with 1-mm–reduced monolithic zirconia crowns (3Y-TZP, Katana HTML, Kuraray, Japan) and mounted in Modupro models. Teeth were assigned to two groups (n = 16 each): guided …
