The increased awareness of the possible harmful effects of ionizing radiation has resulted in concern at the number of panoramic radiographs taken in General Dental Practice. A study has been carried out to examine the diagnostic value obtained from panoramic radiographs taken at 9–10 years of age. Nine-hundred and-eighty-two radiographs were examined and 261 (26·5 per cent) showed findings which would be of significance in orthodontic diagnosis and treatment planning.
