Dental Care Utilization Among U.S. Children Participating In Early Head Start Programs, Ahlam Ibraheem Joufi

Health Services Research Dissertations

Early childhood caries (ECC) remains one of the most common preventable diseases among children under the age of 6 years. Several national stakeholders recommend establishing a continuous collaboration of individuals involved with receiving oral health services (dental home) and routine dental care for the child by 12 months. Despite this recommendation, disparities exist among young, low-income children in preventive dental service utilization. The Early Head Start (EHS) program serves low-income children aged 0-3 years and their families and promotes oral health practices and service utilization within the program. This study aims to examine predictors of dental care utilization among children …

Flapless Approach To Dental Implant Surgery: To Use Or Not To Use?, Rebecca Skaf Dds, Kenneth Parrera Dds, Abhiram Maddi Dds, Msc, Phd

The New York State Dental Journal

Flapless approach to implant surgery is emerging as a viable alternative to traditional implant surgery, where a full thickness flap is raised and the alveolar bone is exposed for placement of dental implants. However, there are several disadvantages of the traditional approach including patient morbidity, bleeding and post-operative complications. With the advent of digital technologies such as cone beam computed tomography (CBCT) and 3D printing of surgical guides, flapless surgery has become desirable for implant placement, especially for general dentists. This manuscript discusses the benefits and risks of the flapless approach as compared to the traditional approach for dental implant …

Use Of Dentoalveolar And Zygomatic Implants In Restoration Of Maxillary Defect Following Fibula Free-Flap Reconstruction Failure, Paul Canallatos Dds, Ms, Thom Loree Md, Amanda Colebeck Dds, Ms, Maureen Sullivan Dds

The New York State Dental Journal

Oral cancer resections cause tissue defects which result in functional complications such as masticatory dysfunction, dysphagia, articulation and phonation issues. When the defect involves the maxillary arch, obturation is needed whether it be surgical or prosthetic. In cases where surgical procedures become ineffective, prosthetic options could be challenging. This is a case of a 78-year-old male developed the diagnosis of squamous cell carcinoma of the right alveolar ridge. The patient underwent partial maxillectomy and right neck dissection with fibula free-flap reconstruction of the maxillary arch. Despite a positive doppler reading, the fibula free-flap became non-vital seven days post-operatively. At the …

Exploring The Experiences Of Underrepresented Students Pursuing Health-Related Graduate Or Professional Programs, Alison Williams

Electronic Theses and Dissertations

For many years graduate and professional education programs for the health professions have sought to increase the diversity of their student body to include students from a wider variety of backgrounds. Increasing the diversity of healthcare providers is an essential component of addressing inequities in healthcare. However, despite initiatives to increase racial and ethnic diversity in the health professions, these professions remain largely White and female. Previous researchers have sought to identify the reasons that racial and ethnic minorities are underrepresented in healthcare, and the barriers to persistence and success. Little research exists explaining why men are underrepresented in the …

Vaccination Intention And Uptake Within The Black Community In Appalachia, Jamey T. Brumbaugh, Kalo C. Sokoto, Casey D. Wright, Sarah E. Francis, Jaliyah Hubbard, Linda Alexander, Daniel W. Mcneil

School of Dentistry Faculty Research and Publications

Objective:

Black communities have disproportionately experienced adverse health effects from the COVID-19 pandemic while simultaneously having less vaccination access and decreased vaccine utilization. As such, predictors of vaccination uptake within Black communities are a public health imperative. Black Americans from socio-geographic regions associated with health inequities (e.g., Appalachia), including vaccination disparities, represent an intersection of racial, economic, and ethnic social identities. To better understand the preventive health needs of Black communities in Appalachia and elsewhere, this study examined psychosocial predictors of vaccination intention or behavior.

Method:

Adults (n = 336) identifying as Black or African American from West …

Hipaa Update: Conducting A Security Risk Analysis, Jennifer Cosey

The Journal of the Michigan Dental Association

The Health Insurance Portability and Accountability Act (HIPAA) Security Rule mandates periodic security risk analyses (SRA) to assess compliance. This analysis evaluates threats and vulnerabilities to electronic protected health information (EPHI) and considers all devices connected to a network. While the Security Rule is flexible, small organizations must still adhere to its standards. IT vendors and staff play a crucial role in implementing HIPAA safeguards. Threats and vulnerabilities must be identified to select appropriate safeguards for EPHI. These safeguards include administrative, physical, and technical measures. Addressable specifications should be implemented if reasonable, and documentation of decisions is essential. A Technical …

Impacts Of A Duf2207 Family Protein On Streptococcus Mutans Stress Tolerance Responses And Biofilm Formation, Xiaochang Huang, Camile G. Laird, Paul P. Riley, Zezhang Tom Wen

School of Dentistry Faculty Publications

Locus SMU.243 in Streptococcus mutans was annotated as a member of the DUF2207 family proteins highly conserved in all bacteria but with unknown function. To investigate its role in S. mutans physiology, a SMU.243-deficient mutant was constructed using allelic exchange mutagenesis, and the impacts of SMU.243 deletion on bacterial growth, stress tolerance response, and biofilm formation were analyzed. Compared to the wild-type UA159, S. mutans lacking SMU.243 displayed a reduced growth rate and a reduced overnight culture density (p < 0.01) when grown at low pH and in the presence of methyl viologen. Relative to the parent strain, the deficient mutant also had a reduced survival rate following incubation in a buffer of pH 2.8 (p < 0.01) and in a buffer containing hydrogen peroxide at 58 mM after 60 min (p < 0.001) and had a reduced capacity in biofilm formation especially in the presence of sucrose (p < 0.01). To study any ensuing functional/phenotypical links between SMU.243 and uppP, which is located immediately downstream of SMU.243 and encodes an undecaprenyl pyrophosphate phosphatase involved in recycling of carrier lipid undecaprenyl phosphate, a uppP deficient mutant was generated using allelic exchange mutagenesis. Unlike the SMU.243 mutant, deletion of uppP affected cell envelope biogenesis and caused major increases in susceptibility to bacitracin. In addition, two variant morphological mutants, one forming rough colonies and the other forming mucoid, smooth colonies, also emerged following the deletion of uppP. The results suggest that the SMU.243-encoded protein of the DUF2207 family in S. mutans plays an important role in stress tolerance response and biofilm formation, but unlike the downstream uppP, does not seem to be involved in cell envelope biogenesis, although the exact roles in S. mutans’ physiology awaits further investigation.

Dental Pulp Stem Cells And Current In Vivo Approaches To Study Dental Pulp Stem Cells In Pulp Injury And Regeneration, Dongwook Yang, Jea Giezl Niedo Solidum, Dongsu Park

Faculty, Staff and Students Publications

Dental pulp stem cells (DPSCs) have garnered significant interest in dental research for their unique characteristics and potential in tooth development and regeneration. While there were many studies to define their stem cell-like characteristics and osteogenic differentiation functions that are considered ideal candidates for regenerating damaged dental pulp tissue, how endogenous DPSCs respond to dental pulp injury and supply new dentin-forming cells has not been extensively investigated in vivo. Here, we review the recent progress in identity, function, and regulation of endogenous DPSCs and their clinical potential for pulp injury and regeneration. In addition, we discuss current advances in new …
