How An Mda Policy Becomes State Law, Daniel Miller Dds, Tom Steinbis

The Journal of the Michigan Dental Association

The MDA Committee on Government and Insurance Affairs is addressing concerns raised by dentists regarding the use of virtual credit cards (VCCs) by insurance companies, which have led to financial challenges such as transaction fees and delayed payments. The MDA has initiated a structured legislative process to resolve the issue, involving data collection, policy review, and drafting a bill in collaboration with legal experts and insurance companies. The legislation, introduced by Rep. Sharon MacDonell, aims to ensure that dental practitioners have alternative payment options that guarantee full reimbursement. The MDA continues to advocate for the bill through the legislative process, …

The New Professional: Debt Repayment Strategies: What New Dentists Should Know, Amrita Patel Dds

The Journal of the Michigan Dental Association

Dentists face significant financial challenges due to educational and practice-related loans. Effective debt repayment strategies are essential for financial stability and long-term success. Dentists should prioritize high-interest debts and explore consolidation or refinancing options to simplify debt management and reduce interest costs. Popular repayment methods include the "snowball" and "avalanche" methods, focusing on either debt balances or interest rates. Income-driven repayment plans for federal educational loans offer flexibility and potential forgiveness. Financial literacy, budgeting, emergency funds, and professional advice are key to successful debt management.

Methadone is a mu (μ) opioid receptor agonist used clinically in adults and children to manage opioid use disorder, neonatal abstinence syndrome, and acute and chronic pain. It is typically marketed as a racemic mixture of R- and S-enantiomers. R-methadone has 30-to 50-fold higher analgesic potency than S-methadone, and S-methadone has a greater adverse effect (prolongation) on the cardiac QTc interval. Methadone undergoes stereoselective metabolism. CYP2B6 is the primary enzyme responsible for catalyzing the metabolism of both enantiomers to the inactive metabolites, S- and R-2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (S- and R-EDDP). Genetic variation in the CYP2B6 gene has been investigated in the context …

The Nature Of Adverse Events In Dentistry, Bunmi Tokede, Alfa Yansane, Muhammad F. Walji, D. B. Rindal, Don Worley, Joel White, Elsbeth Kalenderian

School of Dentistry Faculty Research and Publications

Objectives

Learning from clinical data on the subject of safety with regards to patient care in dentistry is still largely in its infancy. Current evidence does not provide epidemiological estimates on adverse events (AEs) associated with dental care. The goal of the dental practice study was to quantify and describe the nature and severity of harm experienced in association with dental care, and to assess for disparities in the prevalence of AEs.

Methods

Through a multistaged sampling procedure, we conducted in-depth retrospective review of patients’ dental and medical records.

Results

We discovered an AE proportion of 1.4% (95% CI, 1.1% …

The Role Of Policy Entrepreneurs In Understanding Oral Health Care Policy: A Case Study Approach Analyzing Multiple Streams Framework In Nc Oral Health Policy, Lori Gordon Hendrick

School of Public Service Theses & Dissertations

The United States Surgeon General has defined oral diseases as a “silent epidemic” that affects the most vulnerable citizens. More often, this includes those from low socio-economic backgrounds, children, elderly, and many members of ethnic minority groups. Although preventative and treatment modalities have improved over the past fifty years, some Americans continue to have little to no access to educational and preventative programs. The lack of access to dental care for all ages and oral health care literacy remains one of the largest health concerns for American citizens making it a “wicked problem”. Historically, raising Medicaid enrollment has failed to …

A Novel Model Of Autologous Tooth Transplantation For The Study Of Nerve Recruitment, Teresa E. Fowler, Doan T. Bloomquist, Caroline Glessner, Poonam Patel, Jeffrey N. James, Kathryn Bollinger, Lynnette P. Mccluskey, Ryan F. Bloomquist

School of Dentistry Faculty Publications

Background: Limited treatment options exist for damaged nerves and despite impressive advances in tissue engineering, scientists and clinicians have yet to fully replicate nerve development and recruitment. Innervation is a critical feature for normal organ function. While most organs are innervated prior to birth, a rare example of postnatal nerve recruitment occurs in the natural development of secondary teeth during adolescence. Many animals undergo postnatal shedding of deciduous teeth with development and eruption of secondary teeth, a process requiring recruitment of nerve and vasculature to each tooth pulp for viability. Here, the investigators created a novel model for the study …

Effect Of Addition Of Metal Oxide Nanoparticles On The Strength Of Heat-Cured Denture Base Resins: Protocol For Systematic Review And Meta-Analysis Of In Vitro Studies, Pragati Kaurani, Amit Hindocha, Amit Porwal, Abhijit Tambe, Carrie Price, Vidhani Goel, Henry Krasner, Jagdish Khubchandani, Kavita Batra

Department of Medical Education Faculty Research

Background: Metal oxide nanoparticle-reinforced polymethyl methacrylate (PMMA) has been shown to improve mechanical properties, such as strength. Different types of metal oxide nanoparticles have been used previously, but the comparative effect on the strength of heat-cured denture base resins remains unclear. Objective: This is a protocol for a systematic review and meta-analysis that will aim to pool evidence to compare and analyze the effects of the addition of different metal oxide nanoparticles, with varied sizes and concentrations, on the strength (flexural, impact, transverse, compressive tensile strength, and fracture toughness) of heat-cured PMMA. In addition, this review aims to analyze methodological …

Case Title: Uncovering The Truth: The Unexpected Incidental Discovery Of Metastatic Carcinoid Tumor In An Elderly Patient., Kavitha Chittaragi Dr, Shwetha R. Poojary Dr

Radiology Teaching Files

Carcinoid tumors are rare neuroendocrine neoplasms with varied clinical presentations. We report a case of a 70-year-old female patient who presented with history of loose stools, vomiting, and abdominal pain. Imaging revealed a small hyper-enhancing nodule in the small bowel, multiple liver lesions, and a mesenteric mass, all suggestive of metastatic carcinoid disease. Biopsy confirmed a neuroendocrine tumor. As these tumors can remain indolent for years, early detection and treatment are critical for effective management and better prognosis.

Sequence-To-Expression Approach To Identify Etiological Non-Coding Dna Variations In P53 And Cmyc-Driven Diseases, Katherine Kin, Shounak Bhogale, Lisha Zhu, Derrick Thomas, Jessica Bertol, W Jim Zheng, Saurabh Sinha, Walid D Fakhouri

Faculty, Staff and Student Publications

Disease risk prediction based on genomic sequence and transcriptional profile can improve disease screening and prevention. Despite identifying many disease-associated DNA variants, distinguishing deleterious non-coding DNA variations remains poor for most common diseases. In this study, we designed in vitro experiments to uncover the significance of occupancy and competitive binding between P53 and cMYC on common target genes. Analyzing publicly available ChIP-seq data for P53 and cMYC in embryonic stem cells showed that ~344-366 regions are co-occupied, and on average, two cis-overlapping motifs (CisOMs) per region were identified, suggesting that co-occupancy is evolutionarily conserved. Using U2OS and Raji cells untreated …
