- Primary Outcome Measures
Name Time Method <br> 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<br> 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<br>
- Secondary Outcome Measures
Name Time Method 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)
