Oral Manifestations Of Syphilis: A Review Of The Clinical And Histopathologic Characteristics Of A Reemerging Entity With Report Of 19 New Cases, Molly Housley Smith, Richard J. Vargo, Elizabeth Ann Bilodeau, K. Mark Anderson, Anna Trzcinska, Carleigh R. Canterbury, John E. Fantasia, Yeshwant B. Rawal

School of Dentistry Faculty Research and Publications

Background

Syphilis is a sexually-transmitted infectious disease caused by Treponema pallidum. Cases of primary and secondary syphilis are on the rise in the United States, with a 14.4% increase in new cases noted from 2017 to 2018 and an escalation of 71% between the years 2014 and 2018. Fulfilling its nickname of “the great imitator,” oral manifestations of syphilis may mimic a variety of infectious, neoplastic, or immune-mediated processes, both clinically and histopathologically. This large spectrum of appearances can create a diagnostic challenge to the clinician and/or pathologist, leading to delay in diagnosis or misdiagnosis.

Methods

A database of …

Bending And Phase Transformation Properties Of A Force Gradient Nickel-Titanium Orthodontic Wire, Brinda Shah

Master's Theses (2009 -)

Objective: Conventional nickel-titanium (NiTi) archwires have widespread application in orthodontics due to their unique properties and ability to move teeth with light, continuous forces, but a shortcoming is that they apply near-uniform force along anterior and posterior teeth. Since the force needed to effectively move teeth is a function of the root surface area and bony support, these archwires cause single-rooted teeth to move more than the multi-rooted molars. With the advent of laser-engineered force gradient NiTi orthodontic archwires, individual forces may be applied to different segments or individual teeth of the arch to maximize tooth movement. The aim of …

Bolstering Geometric Morphometrics Sample Sizes With Damaged And Pathologic Specimens: Is Near Enough Good Enough?, D. Rex Mitchell, Claire A. Kirchhoff, Siobhán B. Cooke, Claire E. Terhune

Biomedical Sciences Faculty Research and Publications

Obtaining coordinate data for geometric morphometric studies often involves the sampling of dry skeletal specimens from museum collections. But many specimens exhibit damage and/or pathologic conditions. Such specimens can be considered inadequate for the analyses of shape and are excluded from study. However, the influences that damaged specimens may have on the assessment of normal shape variation have only been explored in two-dimensional coordinate data and no studies have addressed the inclusion of pathological specimens to date. We collected three-dimensional coordinate data from the cranium and mandible of 100 crab-eating macaques (Macaca fascicularis). Tests typically employed to analyze shape variation …

Bioresorbable Composite Polymeric Materials For Tissue Engineering Applications, Sakineh Hajebi, Saeed Mohammadi Nasr, Navid Rabiee, Mojtaba Bagherzadeh, Sepideh Ahmadi, Mohammad Rabiee, Mohammadreza Tahriri, Lobat Tayebi, Michael R. Hamblin

School of Dentistry Faculty Research and Publications

This review covers the development of bioresorbable polymeric composites for applications in tissue engineering. Various commercially available bioresorbable polymers are described, with emphasis on recent bioresorbable composites based on natural and synthetic polymers. Bioresorbable polymers contain hydrolyzable bonds, which are subjected to chemical degradation via either reactive hydrolysis or enzyme-catalyzed active hydrolysis. For synthetic polymers, chemical hydrolysis is the most important mode of degradation. The degradation rate can be controlled by varying the molecular weight and crystallinity. Examples of bioresorbable polymers are: polyurethane, poly(D,L)lactide, poly(lactic-co-glycolic) acid, poly(α-hydroxy acids), cross-linked polyester hydrogels, poly(orthoesters), polyanhydrides and polyethylene glycol.

Recent Developments In Targeting Genes And Pathways By Rnai-Based Approaches In Colorectal Cancer, Asiyeh Jebelli, Behzad Baradaran, Jafar Mosafer, Amir Baghbanzadeh, Ahad Mokhtarzadeh, Lobat Tayebi

School of Dentistry Faculty Research and Publications

A wide spectrum of genetic and epigenetic variations together with environmental factors has made colorectal cancer (CRC), which involves the colon and rectum, a challenging and heterogeneous cancer. CRC cannot be effectively overcome by common conventional therapies including surgery, chemotherapy, targeted therapy, and hormone replacement which highlights the need for a rational design of novel anticancer therapy. Accumulating evidence indicates that RNA interference (RNAi) could be an important avenue to generate great therapeutic efficacy for CRC by targeting genes that are responsible for the viability, cell cycle, proliferation, apoptosis, differentiation, metastasis, and invasion of CRC cells. In this review, we …

Inventing Dental Continuing Education: History Of The Dental Forum -- Milwaukee, Kenneth J. Waliszewski

School of Dentistry Faculty Research and Publications

Life-long learning is an ancient concept. The young are unaware of it. A beginning practitioner, often blinded by ego, ignores its value. The seasoned veteran, haunted by challenges, wonders how it passed him by. History can and does often teach us lessons. In 1787, Benjamin Franklin stood up to address the American Constitutional Convention and urged his fellow patriots to sign the document. At the age of 81, he was the oldest person in the group. He acknowledged having opened his mind to contrarian viewpoints from his younger colleagues. Franklin spoke these words: “If you are convinced that you know …
