Is Being A Shareholder ‘In Name Only’ A Problem?, Daniel Schulte Jd

The Journal of the Michigan Dental Association

This column addresses the legal risks for Michigan dentists entering "shareholder in name only" agreements with non-dentist entities. Michigan law requires dental practices to be owned by licensed dentists to ensure professional control over public healthcare. Arrangements where management companies or manufacturers can reclaim stock for a nominal fee effectively strip the dentist of true ownership. This lack of control can lead to ethical conflicts, such as pressure to sell specific appliances regardless of professional judgment. Engaging in such schemes may endanger a dentist's license by thwarting state laws intended to protect clinical independence.

The author emphasizes the importance of listening to long-term patients to understand their history and build trust. While new practitioners often feel the need to prove technical skills, patients primarily seek reassurance and continuity of care. Successful transitions require a balance between respecting existing systems and gradually introducing a new perspective. Introductions by the senior doctor can significantly ease patient apprehension. Ultimately, the experience underscores that dentistry is deeply rooted in relationships and communication, requiring patience and humility to maintain the stability of the …

When Should I Pay For Continuing Education?, Jodi Schafer Sphr, Shrm-Scp

The Journal of the Michigan Dental Association

This article outlines legal requirements for compensating staff for Continuing Education (CE) under the Fair Labor Standards Act. Training time is considered "hours worked" unless it is voluntary, outside regular hours, non-job-related, and involves no productive work. If these criteria are not met, employers must pay for training and associated travel time, including it in overtime calculations. While mileage reimbursement is not federally mandated, many practices offer it as a benefit. Creative cost-saving measures include stipends or in-office lunch-and-learns. Establishing a clear, written policy in the employee handbook is essential for consistent application and can serve as a valuable tool …

Tooth Ablation And The Jōmon - Yayoi Transition In Japan, Laura R. Erickson

Theses and Dissertations

The Jōmon – Yayoi period transition in Japan is marked by many migrants coming through the Korean Peninsula into Kyushu, sparking changes such as the introduction of wet-rice agriculture to the native hunter-gatherer-fisher Jōmon population and decreases in tooth ablation patterns and percentages. Ritual tooth ablation, or the removal of healthy front teeth, is typically seen as a coming-of-age practice, with the Jōmon having a diverse amount of ablation patterns. In this study, I explored how the rates and variation of tooth ablation changed throughout Japan after the arrival of Yayoi migrants from the continent. After calculating ablation rates per …

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 …

Comparison Of Three Methods In Diagnosing Maxillary Transverse Discrepancy, Madison Hull Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction

There are several different methods in determining the maxillary transverse discrepancy (MTD). In specific, MTD can be determined with the help of a cone beam computer tomography (CBCT), 3D scan and models, or simply a 2D occlusogram.  Do they provide the same MTD values for diagnosing transverse discrepancies? A patient may need a certain amount of skeletal and dental expansion based on a diagnosis of MTD, but this amount may vary depending on the diagnosis method used. There is a lack of knowledge in the literature comparing 2D and 3D methods in determining MTD. Currently, methods in measuring MTD …
