Labial Reduction Guide For Laminate Veneer Preparation, Seok-Hwan Cho, William W. Nagy

School of Dentistry Faculty Research and Publications

This article describes a method of fabricating a labial reduction guide for laminate veneer preparations by using a digital tire tread depth gauge and orthodontic wire. The labial reduction guide can help clinicians to achieve accurate reduction of the labial surface. Minimally invasive porcelain laminate veneers have become a popular option in esthetic dentistry. Porcelain laminate veneers require only 25% to 50% of the amount of tooth reduction required for complete coverage restorations.Nevertheless, adequate labial reduction is important in creating optimal esthetics. However, excessive reduction can lead to compromised bond strength due to penetration of the enamel surface. Typically, the …

Journal of Health Disparities Research and Practice

Severe Early Childhood Caries (S-ECC) is a terribly aggressive and devastating disease that is all too common in lower socio-economic children, but none more so that what is encountered in American Indian Tribes. Nationwide, approximately 27% of 2-5 year olds have decay while 62% percent of American Indian/Alaska Native children in the same age group have a history of decay (IHS 2010, NHANES 1999-2002). We have conducted a study of children from birth to 36 months of age on Pine Reservation to gain a better understanding of the variables that come into play in the development of this disease, from …

Mass Spectrometric Analyses Of Surface Proteins From Candida Albicans After Treatment With Histatin 5, Shirley Fan

Electronic Thesis and Dissertation Repository

Current drug therapies have lost their effectiveness in controlling the fungal species known as C. albicans; therefore, the need for newer drugs becomes crucial. Histatin 5 (Hst 5), a naturally occurring peptide found in the oral cavity, has demonstrated strong effects on controlling candidiasis. Here, we have proposed that the adhesion of cells through surface proteins is an important process. To allow the analysis of surface proteins, the concept of on-whole cell tryptic digestions were developed. This on-target approach allows for isolation of the peptides of interest, while greatly reducing digestion times.

To study the effects of Histatin 5 …

Effect Of Dexamethasone Prodrug On Inflamed Temporomandibular Joints In Juvenile Rats., Mitchell Knudsen, Matthew Bury, Callie Holwegner, Adam L. Reinhardt, Fang Yuan, Yijia Zhang, Peter J. Giannini, David B. Marx, Dong Wang, Richard A. Reinhardt

Journal Articles: College of Dentistry

INTRODUCTION: Juvenile idiopathic arthritis (JIA) often causes inflammation of the temporomandibular joint (TMJ) and has been treated with both systemic and intra-articular steroids, with concerns about effects on growing bones. In this study, we evaluated the impact of a macromolecular prodrug of dexamethasone (P-DEX) with inflammation-targeting potential applied systemically or directly to the TMJ.

METHODS: Joint inflammation was initiated by injecting two doses of complete Freund's adjuvant (CFA) at 1-month intervals into the right TMJs of 24 growing Sprague-Dawley male rats (controls on left side). Four additional rats were not manipulated. With the second CFA injection, animals received (1) 5 …

Utilizing Dental Hygienists To Improve Health Outcomes In Long-Term Care, Diana V. Macri

Publications and Research

Poor oral health practices contribute to negative health outcomes for residents of long-term care facilities. The abundance of current information on the oral–systemic connection underscores the need for improved oral hygiene among all citizens but specifically for older adults, who face challenges for self-care due to sensory, mobility, endurance and cognitive deficits. Dental hygienists are oral disease prevention specialists and are trained to perform dental procedures that significantly improve a person’s oral health. Dental hygienists are legally permitted to provide many oral healthcare services to residents of long-term care facilities independent of dentist supervision or in collaborative agreements with dentists. …

Differential Gene Expression Profiles Reflecting Macrophage Polarization In Aging And Periodontitis Gingival Tissues, Octavio A. Gonzalez, Michael John Novak, Sreenatha S. Kirakodu, Arnold J. Stromberg, R. Nagarajan, Chifu B. Huang, K. C. Chen, Luis Orraca, J. Martinez-Gonzalez, Jeffrey L. Ebersole

Center for Oral Health Research Faculty Publications

Recent evidence has determined a phenotypic and functional heterogeneity for macrophage populations. This plasticity of macrophage function has been related to specific properties of subsets (M1 and M2) of these cells in inflammation, adaptive immune responses and resolution of tissue destructive processes. This investigation hypothesized that targeted alterations in the distribution of macrophage phenotypes in aged individuals, and with periodontitis would be skewed towards M1 inflammatory macrophages in gingival tissues. The study used a non-human primate model to evaluate gene expression profiles as footprints of macrophage variation in healthy and periodontitis gingival tissues from animals 3-23 years of age and …

Okeson, Eduardo Pondé De Sena

Oral Health Science Faculty Publications

BACKGROUND: Temporomandibular disorders are a group of orofacial pain conditions that are commonly identified in the general population. Like many other chronic pain conditions, they can be associated with anxiety/depression, which can be related to changes in the activity of the dorsolateral prefrontal cortex. Some studies have demonstrated clinical improvement in subjects with chronic pain who are given therapeutic neuromodulation. Transcranial direct current stimulation is a noninvasive brain stimulation technique that allows the modulation of neuronal membranes. This therapy can enhance or inhibit action potential generation in cortical neurons. In some instances, medications acting in the central nervous system may …

Force To Debond Brackets From High-Fusing And Low-Fusing Porcelain Systems, Nicholas P. Ferri, Theodore Eliades, Spiros Zinelis, T. Gerard Bradley

T. Gerard Bradley

The purpose of this study was to test the hypothesis that porcelain surface finishing, ie, low- and high-fusing porcelain, has an effect on the amount of force required to debond orthodontic brackets. A total of 20 high-fusing and 20 low-fusing porcelain specimens were prepared, polished, and bonded with standard edgewise brackets using a suggested porcelain bonding protocol. The brackets were debonded with a universal testing machine at shear mode. Resin removal was performed using two methods: a multifluted carbide bur with and without the use of Sof-Lex polishing discs. Representative specimens were studied under a scanning electron microscope before and …
