“…The variation of study design was evident, as this systematic review included studies performed on cadavers 30 , on patients 33,35,36 , using child and adult phantoms 27,31,34,35,37 and using simulations (Monte Carlo algorithm) 26,28,29 . The studies that used computer simulation found reduction of radiation dose in the range of 50%-75% with rectangular collimation.…”

“…Of the 13 studies included, three used the Monte Carlo method for calculating radiation doses 26,28,29 while the remainder used dosimetry. Of the studies that used dosimetry, some assessed absorbed or effective dose while exposing patients 32,33,36 , while others used phantoms 1,27,31,34,35,37 and cadaver heads 30 . Only one 1 included digital radiography, phosphor storage plates (PSP) in its analysis, three 26,28,34 did not calculate doses for any particular type of film, while the rest investigated the research question assessing D-, E-or F-speed conventional films.…”

Panoramic Dental Radiography for Mass Screening?

Dental panoramic radiography has increased in popularity and use since its introduction in the late 1950's and proposals have been made to apply this methodology as a mass screening tool. Ease of examination and the reportedly low radiation exposure to the anterior superficial tissues have been cited as reasons for this application. However, in panoramic radiography the X-ray beam enters posteriorly which results in high doses to posterior and to internal tissues. We have employed LiF thermoluminescent dosimeters to measure the radiation exposure to the superficial tissues of a Rando phantom and of patients during dental panoramic examination. Radiation exposures ranged from an average of 255 mR to the lateral tissues to 22 mR to the symphysis of mandible. Other anterior superficial tissues received exposures of 25-50 mR. On the basis of previous hazards analysis of radiographic procedures, these radiation exposures would seem to be excessive for application as a mass screening tool.
