Oral Health Considerations For Aging Patients Living With Hiv/Aids, Madeleine Daily Dds, Susan Liu Dds, Yuna Park Dds, Mph, Ms, Emily Byington Msw, Ivette Estrada Ma, Mphil, Sunil Wadhwa Dds, Carol Kunzel Phd

The New York State Dental Journal

People living with HIV/AIDS (PLWH) have an increased life expectancy due to advances in antiretroviral therapy. In 1996, the life expectancy for a 20-year old living with HIV was 39-years old; today, it is >70-years old. As life expectancy increases, PLWH are burdened with age-associated comorbidities. This paper reviews the interaction between aging and HIV and how it affects social, physical, and oral health issues. The shift in demographics presents new challenges for clinicians in how to identify, address, and manage these complex manifestations. This review summarizes how to approach HIV-related changes when providing care as a dental clinician.

Running For Political Office: These Dentists Did . . . How About You? Insights From Two Dentist-Legislators, W. Erick Rupprecht Dds, Lynn Aronoff

The Journal of the Michigan Dental Association

The Michigan Dental Association encourages members to seek political office. Why? Having a member dentist hold an elected office improves the profession's visibility and builds relationships with other elected officials and community leaders who can support dentistry's goals. A dentist-legislator becomes a resource with their legislative colleagues when they debate health policy, regulations, and business initiatives. Having member dentists on the inside provides receptive ears when the Association advocates for the profession's needs and priorities.

To give insight into what public service by a dentist looks like, the Journal interviewed two colleagues who have made that commitment, State Representative Steven …

A Dentist's Role In The Delivery Of Culturally Competent Oral Health Care To Transgender Patients, Laura Rhein Dds, Benjamin Solomowitz Dmd, Michael Mand Dds

The New York State Dental Journal

The importance of delivering patient-centered care is understood by professionals across all healthcare fields. But to deliver such patient-centered care involves understanding various patient populations, especially marginalized populations. Rendering non-biased, non-prejudicial care to marginalized populations is irrefutably critical. To do so, it requires understanding the specific needs of these at-risk populations to deliver high quality patient-centered care. The transgender community is one marginalized population that faces inequities in healthcare. This article seeks to examine current literature to reveal such inequities that the transgender population encounters in dental care and to explore the dentist’s role in the delivery of culturally competent …
