Design outcomes

Primary

MeasureTime frame
1. Diagnostic performance of the images assessed using detection of anatomical landmarks (25 landmarks on dental panoramic tomogram and 35 landmarks on lateral cephalogram) after the x-rays were taken 2. The presence of nuclear alterations (pyknosis, karyolysis, karyorrhexis and nuclear budding) of buccal mucosa smear was noted (yes/no), taken before the exposure to x-rays and 10 days after the x-rays

Secondary

MeasureTime frame
Quality of the images assessed using a five-point rating scale after the x-rays taken (1= excellent, 2= more than adequately presented, 3= adequately presented 4= barely adequately presented, 5= inadequately presented)
