From State House To World Health Assembly: The Distinct Missions Of National And International Leadership In Oral Healthcare, Robert A. Faiella Dmd, Mmsc., Mba, William R. Calnon Dds, Facd

Journal of the American College of Dentists

Leadership in oral healthcare has long been treated as a skill assimilated over time through experience rather than intentionally defined, taught, and assessed. Unlike clinical practice, education, research, and infection control, leadership in oral healthcare lacks consistent standards despite its critical role in integrating these systems and guiding the profession’s future. As healthcare becomes increasingly collaborative and global, dentistry must deliberately develop leadership capabilities at multiple levels. This article examines leadership at the national and international levels, using the American Dental Association’s role within U.S. and global health and dental organizations as examples. It explores why these leadership contexts require …

Dental Implantology: A Literature Review, Kylie Taylor

Undergraduate Honors Theses

Dental implant therapy is the process of replacing teeth as a form of treatment to improve quality of life, function, and esthetics. The success of the implant depends on the surgical technique, type of prosthetic, and factors related to individual patients. The most important factor for implant success is osseointegration. Osseointegration is a process in which success is determined by the bone quality, the surface characteristics of the implant and the surgical approach. Some approaches to improve the osseointegration of the implant are low-speed drilling, guided surgery, and reduced surgical trauma at the site. The impact of systemic conditions, health …

What Is A Standard? Perspectives On Acd’S Standards For Leadership In Oral Healthcare, N. Karl Haden Phd, Facd

Journal of the American College of Dentists

The American College of Dentists’ new Standards for Leadership in Oral Healthcare mark the first attempt in dentistry to articulate standards specifically for leadership, complementing the broader orientation offered by the Ethics Handbook for Dentistry. This article explores the basic question, “What is a standard?” Close reading of the document indicates at least three distinct but related senses of the term: an expectation, a norm, and a guiding principle. The article offers an interpretation of how these three senses fit together coherently. Referencing the Handbook, the article argues that the leadership standards are most impactful only when habituated, when practiced …
