Admission Systems To Dental School In Europe: A Closer Look At Flanders, Tine Buyse, Filip Lievens, L. Martens

Research Collection Lee Kong Chian School Of Business

Dental education in Europe faces enormous challenges. One deals with the admission to dental school. Although admission procedures vary considerably across Europe, a characteristic of some systems is that the same procedure is used across students who will ultimately pursue different majors (medical or dental). This is based on the assumptions that there is no significant difference in these students' scores and that the requirements for medicine and dentistry are equal. This study examines these assumptions in the admission exam 'Medical and Dental Studies' in Flanders. Students who pass may choose whether they start medical or dental education. Over an …

Compensating Associates For Supervising Dental Hygiene Production In U.S. General Dental Practices: A Discussion Of A Frequently Taboo Topic, David G. Dunning, Brian M. Lange, Robert Madden

Journal Articles: College of Dentistry

Many associateship employment contracts in U.S. general dental practice, probably about 85% based on our review of over 100 contracts in the past decade, are silent about a key issue in associateships-- namely, compensating associates for supervising dental hygiene production. Not addressing this issue raises ethical questions as well as concerns about professional liability regarding the supervision of dental hygiene. The associate and owner need to include in an employment agreement what compensation will be given to the associate for supervising dental hygiene production. Compensating associates for supervising dental hygiene production will certainly have a …

The Human Oral Microbiome, Floyd E. Dewhirst, Tuste Chen, Jacques Izard, Bruce J. Paster, Anne C. R. Tanner, Wen-Han Yu, Abirami Lakshmanan, William G. Wade

Department of Food Science and Technology: Faculty Publications

The human oral cavity contains a number of different habitats, including the teeth, gingival sulcus, tongue, cheeks, hard and soft palates, and tonsils, which are colonized by bacteria. The oral microbiome comprises over 600 prevalent taxa at the species level, with distinct subsets predominating at different habitats. The oral microbiome has been extensively characterized by cultivation and culture-independent molecular methods such as 16S rRNA cloning. Unfortunately, the vast majority of unnamed oral taxa are referenced by clone numbers or 16S rRNA GenBank accession numbers, often without taxonomic anchors. The first aim of this research was to collect 16S rRNA gene …

Trail, Dr5 And Caspase 3-Dependent Apoptosis In Vessels Of Diseased Human Temporomandibular Joint Disc. An Immunohistochemical Study, Carla Loreto, Luis Eduardo Almeida, M. R. Migliore, M. Caltabiano, Rosalia Leonardi

School of Dentistry Faculty Research and Publications

To evaluate the apoptosis involvement in the angiogenesis as a self-limiting process in patients with temporomandibular joint (TMJ) degenerated disc vessels, we assessed, by immunohistochemistry, the detection of TRAIL, its death receptor DR5 and caspase 3. TRAIL, its death receptor DR5 and caspase 3 expression were studied by immunohistochemistry in 15 TMJ discs displaced without reduction and in 4 unaffected discs. These apoptosis molecules were detected in the intima and media layers of newly formed vessels affected discs. In conclusion, vessels apoptosis activation in TMJ disc with ID could be regarded as a self-limiting process that try to leads to …

Hiv-1 Reactivation Induced By The Periodontal Pathogens Fusobacterium Nucleatum And Porphyromonas Gingivalis Involves Toll-Like Receptor 2 And 9 Activation In Monocytes/Macrophages, Octavio A. Gonzalez, Mengtao Li, Jeffrey L. Ebersole, Chifu B. Huang

Center for Oral Health Research Faculty Publications

Although oral coinfections (e.g., periodontal disease) are highly prevalent in human immunodeficiency virus type 1-positive (HIV-1⁺) patients and appear to positively correlate with viral load levels, the potential for oral bacteria to induce HIV-1 reactivation in latently infected cells has received little attention. We showed that HIV-1 long terminal repeat (LTR) promoter activation can be induced by periodontopathogens in monocytes/macrophages; nevertheless, the mechanisms involved in this response remain undetermined. Since Toll-like receptor 2 (TLR2), TLR4, and TLR9 activation have been involved in HIV-1 recrudescence, we sought to determine the role of these TLRs in HIV-1 reactivation induced by …

Soft Tissue Grafting To Improve Implant Esthetics, Moawi M. Kassab

School of Dentistry Faculty Research and Publications

Dental implants are becoming the treatment of choice to replace missing teeth, especially if the adjacent teeth are free of restorations. When minimal bone width is present, implant placement becomes a challenge and often resulting in recession and dehiscence around the implant that leads to subsequent gingival recession. To correct such defect, the author turned to soft tissue autografting and allografting to correct a buccal dehiscence around tooth #24 after a malpositioned implant placed by a different surgeon. A 25-year-old woman presented with the chief complaint of gingival recession and exposure of implant threads around tooth #24. The patient received …

Dental Hypotheses: Seeks To Publish Hypotheses From All Areas Of Dentistry, Edward F. Rossomando

UCHC Articles - Research

Starting a new open access journal in a rapid growing scientific panorama is a severe challenge. However, the first issue of dental hypotheses is now history and the even skeptics can appreciate that dental hypotheses is a success - it is a journal of high quality that provides an outlet for publication of articles that encourage readers to question dental paradigms. But dental hypotheses readers might have noticed that the majority of the articles published in the first issue of dental hypotheses concern clinical dentistry. However, dental hypotheses editors recognize that there are many other areas in dentistry that present …

Oral Mucositis: The New Paradigms, Rajesh V. Lalla, Douglas E. Peterson

UCHC Articles - Research

Purpose of review

Mucositis has long been viewed as an unavoidable consequence of high-dose chemotherapy and/or radiation. Management has been directed to supportive care including oral pain control, nutritional support, infection treatment and control of diarrhea. While these interventions have been valuable for clinical management, they have not been collectively directed to molecularly targeted prevention and treatment. This review addresses recent advances regarding mucosal injury in cancer patients, with emphasis on symptom clusters, genetically-based tissue susceptibility and risk prediction, imaging technology, and computational biology.

Recent findings

Modeling of symptom clusters in cancer patients continues to mature. Although integration of mucositis …

Provision Of Fluoride Varnish Treatment By Medical And Dental Care Providers: Variation By Race/Ethnicity And Levels Of Urban Influence, Christopher Okunseri, Aniko Szabo, Raul I. Garcia, Scott Jackson, Nicholas M. Pajewski

School of Dentistry Faculty Research and Publications

Objective: In 2004, Wisconsin Medicaid policy changed to allow medical care providers to be reimbursed for fluoride varnish treatment (FVT) to children's teeth to improve access and utilization. To date, no study has been published on whether geographic and racial/ethnic variation in the provision of FVT in response to this policy change exists. This study's objective is to examine the association of rates of FVT for children enrolled in Wisconsin Medicaid with race/ethnicity, urban influence codes (UIC), and dental health professional shortage area (DHPSA) designation based on county of residence.

Methods: A retrospective, pre–post design was used based on FVT …

Influence Of Blood Contamination On Bond Strength Of A Self-Etching System, Ellen Cristina De Carvalho Mendonça, Samuel Nilo Vieira, Fernando Aparecido Kawaguchi, John Powers, Adriana Bona Matos

Student and Faculty Publications

OBJECTIVES: To detect the influence of blood contamination (BC) on the bond strength (BS) of a self-etching bonding system (SES) to enamel and dentine.

METHODS: 25 human molars were longitudinally sectioned on the mesio-distal axis in order to obtain 50 specimens, which were embedded in acrylic resin. At first, the specimens were ground to expose a flat surface of enamel, and a bond strength test was performed. Afterwards, the samples were ground again in order to obtain a flat surface of dentine. Ten groups (total: n=100) were assigned according to substrate (enamel and dentine), step in the bonding sequence when …
