dental medicine Accomplishments

Katherine Howard (Dental) is the senior author of "Alterations in Oral Cancer Gene Expression in Response to Melatonin" in the Journal of Complementary and Alternative Medical Research with Arin Hartounian, Guillermo Alessandro Retis, and Karl Kingsley (all Dental).

UNLV School of Dental Medicine faculty and students participated in a recent remote area medical event in Pahrump and provided routine tooth extractions, surgical extractions, and front teeth restorations free of charge to approximately 15 children and 110 adults. The volunteering dental students worked more than eight hours during their Saturday and Sunday shifts. Medical exams and vision checks also were provided to people in need. The School of Dental Medicine has been asked to participate again next year.

Drs. Edward Lynch and Martin Grootveld (both Dental) co-authored “Fluoride Releasing Capacity of Newly Developed Atraumatic Restorative Materials” in the international online, open-access, peer-reviewed Journal of Evolution of Medical and Dental Sciences. The collaborative study included faculty from UNLV School of Dental Medicine; NITTE University department of oral biology and genomic studies, India; the global child dental health unit in Kings College London; and the bioanalytical chemistry and chemical pathology in the biomedical & environmental health department in De Montfort University, United Kingdom. The team developed two new and cost-effective atraumatic restorative treatment materials and assessed their fluoride-releasing capacities. Both biomaterials released fluoridethroughout the physiologically-relevant study time periods. Fluoride ion-release is effective in the prevention of secondary caries (cavities), and the materials could be considered a less invasive approach to managing holes in teeth.

Drs. Edward Lynch and Dr. Martin Grootveld (both Dental) recently published “Mutagenicity Potential of New Atraumatic Restorative Treatment (ART) Materials Incorporated with Azadirachta Indica (Neem) against Salmonella typhimurium” in the international online, open access, peer-reviewed Elsevier Journal of Oral Biology and Craniofacial Research. The collaborative study included faculty from UNLV School of Dental Medicine; NITTE University department of oral biology and genomic studies, India; the global child dental health unit in Kings College London; and the bioanalytical chemistry and chemical pathology in the biomedical & environmental health department in De Montfort University, United Kingdom. The project used the Ames test (genotoxicity) to study the mutagenicity potential of two new atraumatic restorative treatment (ART) materials against Salmonella typhimurium without metabolic activity. Both ART materials exhibited weak mutagenic effects on S. typhimurium TA98, whereas no mutagenic effect was detected on S. typhimurium TA100.

Katherine Howard (Dental) is the senior author of "Differential miRNA Expression in Oral Cancer Oncosomes: A Pilot In Vitro Study" in the International Research Journal of Oncology with Dannica Brennan, Kunal Patel and Karl Kingsley (all Dental).

Drs. Edward Lynch and Martin Grootveld (both Dental) recently published “Twelve Hour Longevity of the Oral Malodor-Neutralizing Capacity of an Oral Rinse Product Containing the Chlorine Dioxide Precursor Sodium Chlorite” in the international online, open-access, peer-reviewed Journal of Oral Health and Dentistry. The collaborative study comprised faculty from UNLV School of Dental Medicine and the bioanalytical chemistry and chemical pathology in the biomedical & environmental health department in De Montfort University, United Kingdom. The study investigated the effectiveness and longevity of an oral rinse product containing 0.10 percent (w/v) of the chlorine dioxide precursor sodium chlorite on oral malodor in participants throughout a 12-hour daylight diurnal cycle. Findings showed the oral rinse effectively blocked VSC production in the oral cavity for a period of 12 hours, likely due to the ability of its active ClO2- ingredient that exerted a combination of biochemical and microbicidal actions in vivo. The product’s longevity of oral malodor-neutralizing actions is clinically significant in view of VSCs involvement, particularly CH3SH, in the pathogenesis of gingivitis and periodontitis.

Marcia Ditmyer (Dental) received a five-year, $1 million from the Department of Health and Human Services’ Health Resources & Services Administration designed to aid the School of Dental Medicine in recruiting and retaining junior full-time clinical faculty.

Dr. Edward Lynch (Dental) co-authored “Fluoride in Fish Flesh, Fish Bone and Regular Diet in the South-Coastal Area of Karnataka State of India,” which appeared in the Indian Journal of Dental Research. The collaborative study involved faculty and students from UNLV School of Dental Medicine; NITTE University department of oral biology and genomic studies, India; the Global Child Dental Health unit in Kings College London; and the Bioanalytical Chemistry and Chemical Pathology in the Biomedical & Environmental Health department in De Montfort University, United Kingdom. The study estimated the fluoride content in regular food items available, including fish, in a coastal area of the South Karnataka state of India. The concentrations of fluoride in foods (nonfish, vegetarian food) ranged from 0.85 to 7.09 ppm and that in fish samples ranged from 1.45 to 2.30 ppm. The highest concentrations were 3.16 ppm in Rohu fish flesh, and 7 ppm in rava dosa (a vegetarian food). The Rohu (Labeo rohita) fish species were found to contain the highest concentrations of fluoride in bone. The fluoride in the fish flesh was also high at 2.28 ppm. Among the regular food items, rava dosa (a thin and crispy crepe made from rava and rice flour) preparation had the highest level of fluoride. These values help provide valid information regarding fluoride intake as well as for the future development of recommended dietary fluoride intake recommendations. The Indian Journal of Dental Research is the official publication of the Indian Society for Dental Research and the India section of the International Association for Dental Research.

Sixteen School of Dental Medicine faculty and students recently participated in a service mission trip to Bolivia where they treated 30 children and adults who had severe fluorosis. While not common in the United States, fluorosis stains teeth dark green or brown due to extreme fluoride levels in drinking water. The seven-day trip immersed students in a new culture, introduced them to other access-to-care issues, and enabled them to restore their patients’ self-confidence by providing healthy smiles. Two faculty members and 14 students made the trip to Bolivia.

Karl Kingsley (Dental) recently published the article "UpFolic Acid-Modulated Growth of Dental Pulp Stem Cells (DPSCs)" in the peer-reviewed Journal of Medical Discovery with two former dental students, Kristi Agari and Weiye Lin.
