Materials and Methods: An expert focus group selected 20 LCI’s for this observational study. A pilot study was conducted for sample size calculation for the main study. In the main study, an eye tracking system was used to accrue multiple parameters for all three groups (ORs, LEOs and MEOs), searching 5 normal and 15 LCIs of varying levels of subtlety for the presence of abnormalities. Participants included 13 ORs, 13 LEOs, and 13 MEOs. A two- way repeated measures ANOVA was performed using SPSS, and generated heat maps and scan paths were used to explore examination performance, search patterns and strategies for visual interpretation between the groups. Results: No statistically significant difference was found for the effect of experience level (OR, LEO, MEO) on viewing parameter of an image overall, an area of interest (AOI), and image region. No statistically significant difference was found for the interaction of experience, viewing parameter, and image type. There were statistically significant differences by image type on specific overall viewing parameter (total distance covered and number of blinks), AOI viewing parameter (time before first fixation, total time examining, number of fixations and number of revisits) and region viewing parameter (time before first fixation, total time examining, number of fixations and number of revisits). Conclusion: These findings indicate that experience does not affect overall examination performance of lateral cephalometric images, AOIs, and region, and there are no interactions affecting examination performance between the experience and image, AOI and region. Experience aside, different levels of image and AOI subtlety and lateral cephalometric image region do affect examination performance."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["From Novice to Expert: An Evaluation of the Examination Performance of Orthodontic Residents and Experienced Orthodontists of Lateral Cephalometric Images"]}]}],"canonical_facts":{"dc:contributor":["Al-Jewair, Thikriat","Orthodontics"],"dc:creator":["Kaplan, Sarah; 0000-0003-1839-8072"],"dc:date":["2018-06-28T20:34:50Z","2018","2018-05-30 16:11:00"],"dc:description":["M.S.","Objective: To evaluate the examination performance of orthodontic residents (OR), less experience orthodontists (LEOs, <10 years post-residency) and more experienced orthodontists (MEOs, >10 years post-residency) of lateral cephalometric images (LCIs) using an eye-tracking device.
