An Assessment Of What Factors Affect The Average Number Of Caries Seen Per Visit Among Children Visiting A Mobile Dental Unit In South Central Kentucky, Breion Douglas

Mahurin Honors College Capstone Experience/Thesis Projects

Background: Dental caries is the single most common chronic childhood disease in Kentucky affecting 20% of preschoolers, 50% of second graders, and 75% of 15 year olds. Dental caries, also known as tooth decay, occurs when bacteria from salivary glands produce an acid to breakdown food. If this acid is not cleaned off the teeth, it can destroy the tooth enamel. Dental problems can be linked to the inability to pay for dental care (i.e. insurance), limited access to dental providers, and parental inability to take their children to dentists. To help address the issue with tooth decay seen among …

On The Symbolism Of The White Coat, David A. Nash

Oral Health Science Faculty Publications

The white coat ceremony has become an academic ritual in the health professions: a ceremony that signals a transformation of status from ordinary student to that of one studying to become a health professional. While donning the white coat is a sign of a changed role, the white coat is also a powerful symbol of transformation. White is a symbol of purity, and the white coat symbolizes the purity of purpose being affirmed in becoming a health professional. Dentistry is afforded the status of a learned profession as a result of the power dentists possess over patients seeking care; this …

Bite Marks On Skin And Clay: A Comparative Analysis, R K. Gorea, O. P. Jasuja, Abdulwahab Ali Abuderman, Abhinav Gorea

Research outputs 2014 to 2021

Bite marks are always unique because teeth are distinctive. Bite marks are often observed at the crime scene in sexual and in physical assault cases on the skin of the victims and sometimes on edible leftovers in burglary cases. This piece of evidence is often ignored, but if properly harvested and investigated, bite marks may prove useful in apprehending and successfully prosecuting the criminals. Due to the importance of bite marks, we conducted a progressive randomised experimental study conducted on volunteers. A total of 188 bite marks on clay were studied. Based on these findings, 93.34% of the volunteers could …

Mastl Kinase, A Promising Therapeutic Target, Promotes Cancer Recurrence., Ling Wang, Vivian Q. Luong, Peter J. Giannini, Aimin Peng

Journal Articles: College of Dentistry

Mastl kinase promotes mitotic progression and cell cycle reentry after DNA damage. We report here that Mastl is frequently upregulated in various types of cancer. This upregulation was correlated with cancer progression in breast and oral cancer, poor patient survival in breast cancer, and tumor recurrence in head and neck squamous cell carcinoma. We further investigated the role of Mastl in tumor resistance using cell lines derived from the initial and recurrent tumors of the same head and neck squamous cell carcinoma patients. Ectopic expression of Mastl in the initial tumor cells strongly promoted cell proliferation in the presence of …

Telomeric Orfs (Tlos) In Candida Spp. Encode Mediator Subunits That Regulate Distinct Virulence Traits, John Haran, Hannah Boyle, Karsten Hokamp, Tim Yeomans, Zhongle Liu, Michael Church, Alastair B. Fleming, Matthew Z. Anderson, Judith Berman, Lawrence C. Meyers, Derek J. Sullivan, Gary P. Morgan

Dartmouth Scholarship

The TLO genes are a family of telomere-associated ORFs in the fungal pathogens Candida albicans and C. dubliniensis that encode a subunit of the Mediator complex with homology to Med2. The more virulent pathogen C. albicans has 15 copies of the gene whereas the less pathogenic species C. dubliniensis has only two (CdTLO1 and CdTLO2). In this study we used C. dubliniensis as a model to investigate the role of TLO genes in regulating virulence and also to determine whether TLO paralogs have evolved to regulate distinct functions. A C. dubliniensis tlo1Δ/tlo2Δ mutant is unable …

An In-Vitro Evaluation Of Mechanical And Esthetic Properties Of Orthodontic Sealants., Thyagaseely Sheela Premaraj, Nima Rohani, David Covey, Sundaralingam Premaraj, Yi Hua, Hidehiko Watanabe

Journal Articles: College of Dentistry

OBJECTIVE: To evaluate mechanical and esthetic Properties of two commercially available orthodontic sealants: Opal(®)Seal (OS) and L.E.D. Pro Seal (PS).

MATERIALS AND METHODS: Discs of each sealant were prepared to test the following properties: Micro hardness, wear resistance and color stability. Samples were randomly selected after the wear test for SEM imaging to analyze surface morphology.

RESULTS: OS was significantly harder than PS (P < 0.001). PS was significantly more wear resistant than OS (P < 0.05). PS showed a greater ∆E*ab (increased staining) when placed in wine or coffee showing a significant difference (P < 0.05). SEM showed particle size, shape and distribution were different for PS and OS reflecting the pattern seen on wear surfaces.

CONCLUSION: Both orthodontic sealants are beneficial for protecting enamel. However with better wear properties PS was superior in resisting mechanical stresses. OS was more color stable.
