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 …

Characterization Of Stem And Progenitor Cells In The Dental Pulp Of Erupted And Unerupted Murine Molars, Anamaria Balic, Hector L. Aguila, Melissa J. Caimano, Victor P. Francone, Mina Mina

UCHC Articles - Research

In the past few years there have been significant advances in the identification of putative stem cells also referred to as “mesenchymal stem cells” (MSC) in dental tissues including the dental pulp. It is thought that MSC in dental pulp share certain similarities with MSC isolated from other tissues. However, cells in dental pulp are still poorly characterized. This study focused on the characterization of progenitor and stem cells in dental pulps of erupted and unerupted mice molars. Our study showed that dental pulps from unerupted molars contain a significant number of cells expressing CD90+/CD45-, CD117+/CD45-, Sca-1+/CD45- and little if …

Ethics, Empathy, And The Education Of Dentists, David A. Nash

Oral Health Science Faculty Publications

Professional education in dentistry exists to educate good dentists-dentists equipped and committed to helping society gain the benefits of oral health. In achieving this intention, dental educators acknowledge that student dentists must acquire the complex knowledge base and the sophisticated perceptual-motor skills of dentistry. The graduation of knowledgeable and skilled clinicians in dentistry is a necessary, but not sufficient, condition for ensuring quality oral health care. The further requirement is the commitment of graduates to applying their abilities with moral integrity: providing appropriate and quality care in their patients' best interest. Ultimately, good dentistry depends on individuals committed to treating …

Effect Of Low-Magnitude, High-Frequency Vibration On Osteocytes In The Regulation Of Osteoclasts, Esther Lau, Saja Al-Dujaili, Axel Guenther, Dawei Liu, Liyun Wang, Lidan You

School of Dentistry Faculty Research and Publications

Osteocytes are well evidenced to be the major mechanosensor in bone, responsible for sending signals to the effector cells (osteoblasts and osteoclasts) that carry out bone formation and resorption. Consistent with this hypothesis, it has been shown that osteocytes release various soluble factors (e.g. transforming growth factor-β, nitric oxide, and prostaglandins) that influence osteoblastic and osteoclastic activities when subjected to a variety of mechanical stimuli, including fluid flow, hydrostatic pressure, and mechanical stretching. Recently, low-magnitude, high-frequency (LMHF) vibration (e.g., acceleration less than < 1 × g, where g = 9.81 m/s², at 20–90 Hz) has gained much interest as studies …

The Human Oral Microbiome Database: A Web-Accessible Resource For Investigating Oral Microbe Taxonomic And Genomic Information, Tsute Chen, Wen-Han Yu, Jacques Izard, Oxana V. Baranova, Abirami Lakshmanan, Floyd E. Dewhirst

Department of Food Science and Technology: Faculty Publications

The human oral microbiome is the most studied human microflora, but 53% of the species have not yet been validly named and 35% remain uncultivated. The uncultivated taxa are known primarily from 16S rRNA sequence information. Sequence information tied solely to obscure isolate or clone numbers, and usually lacking accurate phylogenetic placement, is a major impediment to working with human oral microbiome data. The goal of creating the Human Oral Microbiome Database (HOMD) is to provide the scientific community with a body site-specific comprehensive database for the more than 600 prokaryote species that are present in the human oral cavity …
