PR73 - Assessment of Dental Fiberoptic Transillumination Devices

Thursday, April 26
10:00 AM - 1:00 PM
Room: Exhibit Hall

Objective: The purpose of this study was to assess the illuminance and instrument tip diameter of dental fiberoptic Light-Emitting Diodes (LED) transilluminators. Methods: The light output of each transilluminator was tested using a light meter under standardized conditions and the tip diameter were measured using a micrometer caliper. The tested units were the Novel iPhone attachment (NI), Novel LED attachment (NL), Q-Optics Microscopic Diagnostic Probe (QM), Microlux Transilluminator (MT), Q-Optics Diagnostic Probe HDP-02 (QH2), Q-Optics Diagnostic Probe HDP (QH). Five separate sources of each brand were tested to determine inter-device reliability, and each source was tested ten times to account for intra-device error. A 95% Confidence Interval for the overall mean of each device and tip diameter were calculated. Results: The mean light output (lux) of each device was: 1247 (NI, 95% CI, 1009-1485); 1739 (NL, 95% CI, 1573-1904); 4874 (QM, 95% CI, 4106-5642); 10333 (MT, 95% CI, 6996-13670); 13712 (QH2, 95% CI, 12028-15395); 68200 (QH, 95% CI, 58550-77849). The tip diameter of each device was: 2.01 mm (NI,NL), 0.97 mm (QM), 3.06 mm (MT), 1.58 mm (QH2), (QH). Conclusion: There is considerable variability in light output and tip diameter of commonly used LED transilluminators available on the market. Further research is required to determine the clinical impact of these differences in the identification of cracks and fractures.

Ceib Phillips

Professor and Assistant Dean for Advanced Education / Graduate Programs
University of North Carolina

My PhD was in Anatomy with a dissertation on the 3 dimensional quantification of the temporomandibular joint of primates. This project led me to realize my love of biostatistics. After joining the faculty at UNC-CH, I completed an MPH in Biostatistics from the School of Public Health at UNC-CH. Since that time, I have been the director of the biostatistics liaison program in the School of Dentistry that assists students and faculty with study design, analysis, and report writing. I was the principal investigator of NIH funded projects continuously from 1995 to 2015. My contribution to research has earned peer recognition in both orthodontics and oral and maxillofacial surgery. Current research interests focus on patient-centered outcomes following surgery.

Associate Professor, UNC School of Dentistry

Dr. Rick Walter is Clinical Associate Professor and Director of Clinics at the UNC School of Dentistry. He received his DDS degree from the Universidade Federal de Santa Catarina (Brazil) in 2000 and MS degree in Operative Dentistry from the UNC in 2005. From 2006 to 2011, he was full-time faculty member in the Department of Operative Dentistry at the UNC. In 2011, he moved to UPenn where he was Assistant Professor until early 2014. Dr. Walter returned to the Department of Operative Dentistry at the UNC in 2014 and later became Director of Clinics in Clinical Affairs, in early 2017. Dr. Walter is active in laboratory and clinical research in dental materials, mainly in resin-based restoratives. He also maintains an intramural practice devoted to restorative and esthetic dentistry.
