How Can We Go Far Together In Healthcare Education And Training?, Nader Nadershahi

Journal of the American College of Dentists

“If you want to go fast, go alone. If you want to go far, go together.” This African proverb highlights the importance of collaboration and cooperation to achieve long-term success and impact. This sentiment applies to many aspects of life, and it certainly applies to our reflection on the importance of breaking down the silos that have developed in healthcare. Our healthcare system has been siloed in all aspects, including delivery models, payment systems, education, and training.

Color Stability Of Conventional, 3d-Printed, And Milled Denture Teeth After Immersion In Coloring Agents: An In Vitro Study, Dany Nassif, Nancy Chemaly, Rim Bourgi, Carole Abi-Ghosn, Louis Hardan, Jihad Fakhouri

International Arab Journal of Dentistry

Objectives: This study investigates the color stability of denture teeth made from different materials when subjected to various staining solutions.

Methods: Forty-five A1 shade upper central incisors were divided into three groups: prefabricated, 3D printed, and milled denture teeth (N=45). Each group was further divided into three subgroups, with teeth immersed in coffee, wine, and artificial saliva for up to 120 days (n=5). ∆E values for color change were measured using an Optishade colorimeter.

Results: The type of teeth, type of solution, and immersion time had a significant effect on color stability (p < 0.001). Interactions between the three variables were all significant (p < 0.001). Conventional denture teeth showed slight color changes with saliva (ΔE = 1.256 by day 120), moderate changes with wine (ΔE = 2.893), and more significant changes with coffee (ΔE = 5.208). Milled denture teeth exhibited no color changes with saliva, noticeable changes with wine (ΔE = 5.359), and moderate changes with coffee (ΔE = 3.137). 3D printed denture teeth showed no color changes with saliva, but increased changes with wine (ΔE = 2.533) and highly significant changes with coffee (ΔE = 10.546). Coffee consistently caused the highest ΔE values, especially in 3D printed teeth.

Conclusions: The study …

International Arab Journal of Dentistry

Dens invaginatus, also known as dens in dente, is a dental anomaly resulting from infolding the enamel organ into the dental papilla. Dynamic Navigation Systems (DNS) like Navident, offer real-time guidance during endodontic procedures, proving especially useful in complex cases, such as calcified canals or pulp obliteration. This case report presents a 13-year-old female, who reported the chief complaint of continuous pain in the upper left front tooth region. Based on the clinical and radiographical findings, a diagnosis of pulp necrosis and chronic periapical abscess in relation to maxillary canine (23) was established with dens invaginated palatal canal ( Oehler’s …

From Tricare To Medicaid: Dental Insurance Disparities Among U.S. Veterans And Active Duty Service Members, Madeline K. Mcnutt Ms

Honors Undergraduate Theses

Oral health plays a critical role in systemic well-being, yet dental care access in the United States remains deeply unequal, particularly among low-income and historically marginalized populations. Among those significantly affected are military veterans, who frequently experience barriers to oral healthcare due to eligibility restrictions within the Department of Veterans Affairs (VA) system. This study offers a comparative analysis of dental insurance satisfaction between recipients of Medicaid and the TRICARE Active Duty Dental Program (ADDP), two federally funded programs that reflect the divide between civilian and military healthcare access. While TRICARE ADDP provides comprehensive and uniform coverage for Active Duty …
