Assessment Of Sox2 Expression As A Tumor Stem Cell Marker In Ameloblastoma And Dentigerous Cyst, Haneen Mahmoud Zeen El-Abdeen, Noha Ahmed Mansour, Sherif Yousef Elnagdy, Mohamed Abdel-Monem Tawfik

Mansoura Journal of Dentistry

Objective: The pathogenesis of odontogenic lesions remains unclear; however, a probable explanation could mean the presence of tumor stem cells (TSCs). The preservation of stem cells during early dental development is governed by many transcription factors, including sex-determining region Y (SRY)-box 2 (SOX-2). Numerous studies observed the increased expression of SOX2 in various benign and malignant tumors as its impact on tumorigenesis varies according to tumor type. This research aims to determine the predictive importance of the SOX2 stem cell marker by evaluating its immunoexpression in ameloblastoma (Ab) and dentigerous cyst (DC). Materials and Methods: Twenty-Four samples were part of …

Mansoura Journal of Dentistry

Objective: assessment and comparison between the retention and surface wear of nylon and polyether ketone ketone (PEKK) inserts of locator attachments retaining mandibular implant overdenture. Materials and methods: For this research, six patients, completely edentulous,were selected; each participant had received mandibular implants in the canine regions on each side, followed by locator attachments. Using a crossover design, patients were randomly assigned to receive different mandibular overdentures as follows. 1) Implantretained overdenture with nylon inserts; 2) Implant-retained overdenture with PEKK inserts. Retention measurements were conducted at three-time intervals: T0 (after pickup), T3 (3 months post-insertion of overdenture)and T6 (6 months post-insertion …

Approaches To Care For Children With Special Needs In Dental Settings: Desensitization And Teledentistry, Hannah Bergeron D.M.D., M.S., Chia-En Tsai D.D.S., Giovana Anovazzi D.D.S., M.Sc., Ph.D., James R. Boynton D.D.S., M.S.

The Journal of the Michigan Dental Association

Children with special health care needs (SHCN) are at a heightened risk of developing chronic physical, developmental, behavioral, or cognitive conditions that significantly affect their oral and general health. These children often encounter significant barriers to receiving adequate dental care, which contributes to neglected oral health needs. Common challenges include increased risk of dental diseases due to medication use, oral hygiene difficulties, and dietary restrictions. Newer strategies aimed at overcoming these barriers include the use of dental social stories, desensitization techniques, and teledentistry.

Social stories offer a structured way for parents to help prepare children for their dental visits. Desensitization …

Coaching Authors With Generative Ai, Christopher J. Smiley

AADEJ - The Communicator

This paper outlines a systematic methodology for dental editors to coach authors in the ethical use of generative artificial intelligence (GAI). By adopting "AI-First" or "Write-First" strategies, editors can help authors refine their thesis statements and improve logical flow while maintaining human oversight and intellectual integrity. Dr. Smiley asserts that GAI should be used as a tool to enhance communication rather than replace human creativity, ensuring authors remain accountable for their final expressions.

The Ethical Imperative Of Leadership In Dentistry, Mike Graham, Toni M. Roucka Rn, Dds, Ma, Facd

Journal of the American College of Dentists

Leadership is one of the four pillars of the American College of Dentists, taking its place alongside excellence, ethics, and professionalism. Leadership in dentistry carries an inherent ethical responsibility to uphold the trust and well-being of those who depend on us—our patients, our teams, and the community. When leaders in our field exercise their influence, they wield significant power over patient outcomes, industry standards, and public health policy. With this influence comes an imperative to act ethically, to ensure that decisions are guided by a commitment to care, integrity, and the best interests of those we serve. At the heart …

Journal of the American College of Dentists

The 2024 Ethics Summit, Breaking Down the Silos, convened by the American College of Dentists, marked a pivotal moment in the ongoing discourse on the ethical responsibilities of oral healthcare professionals. This distinguished gathering of interprofessional experts offered an insightful and urgent exploration into one of healthcare’s most pressing yet underexamined ethical imperatives: the moral obligation to fully integrate oral health into the broader healthcare system. The summit’s focus aligns powerfully with the mission of the American College of Dentists to advance excellence, ethics, professionalism, and leadership in oral healthcare.

Racial Diversity Matters: Experiences Of Dental Hygienists Of Color In Education And Practice, Sonika Masih

All Graduate Theses, Dissertations, and Other Capstone Projects

Oral health is important to overall health. Poor oral health can affect a person’s ability to smile and chew, and can negatively affect their self-esteem. Poor oral health can lead to systemic diseases and even death. Therefore, access to dental care is vital for maintaining a quality of life, but people of color often lack access to this essential care. Negative stereotyping, color blind attitudes, and providers' biases are barriers for people of color to access dental care. Dental hygienists play a crucial role in removing barriers to oral healthcare for underserved populations. However, the dental hygiene profession does not …

The Role Of Research In Fostering Dentistry’S Partnership In Healthcare, Scott Tomar Dmd, Drph, Facd

Journal of the American College of Dentists

In 2000, the landmark report Oral Health in America: A Report of the Surgeon General highlighted the magnitude of oral health disparities in the country and emphasized the importance of oral health for overall well-being, calling for a health infrastructure that effectively integrates oral health into overall health. More than two decades later, dental and oral diseases remain prevalent among parts of the American population, key strategies for disease prevention are under attack, and dentistry remains largely isolated from the rest of the US healthcare system. While many factors need to be addressed to change that status, it is widely …
