Comparing Educational Pathways For Denturists To Become Maxillofacial Prosthetic Specialists In The Us And The Uk, Minseok Kim

Oral Health

Abstract

In the absence of formal training, licensure, and professionalism, this scientific literature review will seek to include denturists in the American maxillofacial prosthetics industry. Denturists are oral health professionals who perform oral examination, design, manufacture, and place removable oral prostheses. In other regions of the world, they are also known as clinical dental technologists and dental prosthetists. This practice is not widespread in the US. The review can also be assessed on the model mediated by PRISMA, which is concentrated on the experiences of international education in the United Kingdom, Canada, and Australia, where the concentration further revolves around …

Successful Flexible Bronchoscopic Extraction Of A Dental Foreign Body Aspirated Into The Left Mainstem Bronchus, Alexys Bolden, Hayden Cooper, Lynnetta Payne, Mark Coomes, Mark Cooper

Marshall Journal of Medicine

Foreign body aspiration (FBA) is a potentially life-threatening emergency that commonly occurs in children but varies widely in clinical presentation. Rapid diagnosis and intervention are of the utmost importance to prevent complications such as airway obstruction, infection, and lung injury. While uncommon in adults, most encountered causes occur in the setting of intoxication, neuromuscular weakness, or iatrogenic dental work. Those with dental prostheses are especially susceptible due to the partially attached nature, rendering the risk of accidental dislodgement. This report discusses an uncommon case wherein an 82-year-old male aspirated a dental bridge into his left mainstem bronchus during routine dental …

Alginate Dressings- Revisiting The Past, Oshine Jha, Oshine Jha

Annual Research Symposium

Wound healing in simple terms is the healing of skin which involves various mechanisms. It is not dressings themselves that heal wounds, but the careful selection of appropriate dressings that provide the optimal wound-healing environment for the individual wound. Wound dressings are prepared from biopolymers, synthetic polymers and biomaterials.

Influence Of Abutments Surface (Machined Vs. Laser-Microgrooved) In Soft-Tissue Response During One Year Of Function: Clinical And Biochemical Outcomes Of A Rct With Split-Mouth Design, Elisa Maccari

Annual Research Symposium

To evaluate peri-implant soft tissue behaviour around machined vs laser-microgrooved implants/healing/prosthetic abutments during 1 year of function by assessing IL-6, IL-1b and MMP-8 levels in peri-implant crevicular fluid (PICF).

Dentofacial Effects Of Radiotherapy On Pediatric Population With Retinoblastoma, Kristi Truong

Annual Research Symposium

This literature review investigates the dentofacial consequences of radiotherapy in young patients with retinoblastoma by referencing current research. In addition, the management and rehabilitation of the dentofacial abnormalities, highlighting orthodontic, surgical, and prosthetic approaches, is examined. By understanding the changes of dentofacial development due to retinoblastoma treatment, effective management techniques can be implemented to resolve significant issues, relating to dental and skeletal relationship and facial appearance.

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

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.

Independent Effects Of Hiv And Antiretroviral Therapy On The Oral Microbiome Identified By Multivariate Analyses, Clifford J. Beall, Elizabeth A. Lilly, Carolina Granada, Kelly Treas, Kenneth R.

The oral microbiome is an important predictor of health and disease. We recently reported significant yet modest effects of HIV under highly active antiretroviral therapy (ART) on the oral microbiome (bacterial and fungal) in a large cohort of HIV-positive (HIV+) and matched HIV-negative (HIV-) individuals. As it was unclear whether ART added to or masked further effects of HIV on the oral microbiome, the present study aimed to analyze the effects of HIV and ART independently, which also included HIV- subjects on preexposure prophylaxis (PrEP) therapy. Cross-sectional analyses of the effect of HIV devoid of ART (HIV+ ART- versus matched …

Comparative Analysis Of Proteomics Biomarkers Associated With Residual Ridge Resorption Induced By Denture Wear, Rohana Ahmad, Ainin Sofia Mohamad Napi, Tong Wah Lim, Su Keng Tan, Saiful Anuar Karsani, Musalmah Mazlan, Lay Kek Teh, Steven M. Morgano, Nadim Z. Baba

Makara Journal of Health Research

Background: The biochemical bone turnover markers for residual ridge resorption (RRR) are unclear. Therefore, the present study aimed to determine the biochemical bone turnover markers associated with RRR by comparing proteomics between the compressed mucosa of denture wearers and the non-compressed mucosa of non-denture wearers.

Methods: The mucosal specimens of 11 complete-denture wearers were obtained from the alveolar ridge during surgical implant exposure for implant-retained overdentures. All denture wearers had been edentulous and worn dentures for at least 5 years. The tissues of 11 non-denture wearers were taken from the ridge during minor preprosthetic surgery. The mucosal proteins …

The Influence Of Vitamin D Metabolism On Gene Expression, Matrix Production And Mineralization During Osteoprecursor Cell-Based Bone Development, Shelley S. Mason, Sean S. Kohles, Shelley R. Winn, Randy D. Zelick

Biology Faculty Publications and Presentations

Background: Multipotential precursor cell lines derived from human bone marrow, capable of differentiating into cartilage or bone, may provide a useful tissue development model for studying the regulation and metabolism of putative growth and differentiation factors necessary for tissue regeneration. In mammals, the process of bone development depends on the proliferation and differentiation of osteoblast lineage cells, and the subsequent synthesis and mineralization of bone extracellular matrix (ECM). Vitamin D metabolites play a pivotal role in bone and mineral homeostasis, and are positive factors on bone development. Recently, it was demonstrated that a human-derived engineered osteoblast precursor cell line (OPC1), …
