— ADA scientists and researchers presented scientific abstracts and other works March 11-14 during the 93rd General Session & Exhibition of the International Association for Dental Research.
IADR met in conjunction with the 44th Annual Meeting of the American Association for Dental Research and the 39th Annual Meeting of the Canadian Association for Dental Research.
The presentations given by ADA Science Institute researchers were associated with work done by researchers in the ADA laboratory in Chicago that could be helpful to practicing dentists.
For example, in one study, the performance of several high-speed air-turbine handpieces was tested. The presentation in Boston, "Characterization of Performance and Light-Output for Several High-Speed Air-Turbine Handpiece Brands" by ADA researchers Dan Halpin; Spiro Megremis, Ph.D.; and Henry Lukic, focused on handpiece light output. It found that handpieces with built-in lighting elements distributed light over a greater area than fiber optic handpieces with coupler/tubing connector light sources.
The latest edition of the ADA Professional Product Review includes the complete ADA laboratory evaluation of high-speed air-turbine handpieces and a video on "Power output of your Air-Turbine Handpiece: What You Need to Know." To access this information, visit ADA.org/ppr
At the meeting, ADA researchers Victoria Ong, Dr. Megremis and Henry Shepelak also gave an oral presentation on dental radiometers: "Accuracy of Five Dental Radiometer Brands When Measuring Three Types of Curing Units." An article on dental radiometers will be featured in an upcoming ADA PPR article.
ADA science researchers also gave two poster presentations related to LED curing units: "Interaction of Camphorquinone Photo-Initiator with Energy Delivered from LED Curing Units," by Mr. Lukic and Dr. Megremis; and "Ability of Depth of Cure and Degree of Monomer Conversion to Assess Curing of a Polymer-Based Restorative Material," by Ms. Ong, Dr. Megremis, Mr. Lukic and Mr. Shepelak.
Information on the LED curing units discussed in these presentations can be found in the November 2014 issue of the ADA PPR.
Members of the Science Institute also gave a poster presentation, "Depth of Cure of Bulk-Fill Composites Using Teeth versus Stainless Steel Molds," by Amer Tiba, Ph.D.; Rashad Vinh; Cameron Estrich.
The ADA Foundation Dr. Anthony Volpe Research Center, located in Gaithersburg, Maryland, which performs basic and applied research for the profession to improve oral health care worldwide, also presented at the exhibition.
With 87 years of collaboration with the National Institute of Standards and Technology, the VRC is home to the development of innovations commonly used in dental practice, including research in biomaterial and tissue engineering technologies; new and improved dental materials for treatment and prevention of oral maladies.
At the conference, researchers from the Dr. Anthony Volpe Research Center presented the following:
"Tuning the Photo-activities of TiO2 Nanoparticles Using Dental Resins," an oral presentation by Jirun Sun, Ph.D. and summer interns S. Scierka Watson, Ph.D. (NIST); D. Stanley (NIST); D. Allsopp.
"Risk Assessment and Sensitivity Meta-analysis of Estrogen-Related Hormones on Dry Socket Occurrence," a poster presentation by Diana Bienek, Ph.D.; James Filliben, Ph.D. (NIST).
"Cytotoxic Effect of TEGDMA on Multicellular Layer Generation in Bioscaffolds," an oral presentation by Gili Kaufman, Ph.D.; Elise Tigani (summer intern); Wojtek Tutak, Ph.D.
"Carbonated Hydroxyapatite Cement as a Reference for EPR Biodosimetry System," a presentation by Larry Chow, Ph.D.; Shozo Takagi, Ph.D.; Marc F. Desrosiers, Ph.D. (NIST).
"Effects of Abrasives on F Deposition by Fluoride-Calcium-Phosphate Slurries," a poster presentation by Dr. Takagi, Dr. Chow.
"Developing 3D-Printed Peri-Implantium to Establish Periodontal Hygiene Efficacy," a poster presentation by Steven Feldman, dental student at the University of Maryland School of Dentistry; J. Kim, D.D.S., Ph.D..
Also, Dr. Gary Schumacher (VRC) and Nancy Lin, Ph.D. (NIST) organized a symposium, "Challenges in Measuring Biofilm-Material Interactions."
