Abstract
AIM: To investigate whether health risk may be reduced in a patient population when taking a lateral cephalogram. METHOD: A laboratory study to determine the minimum effective radiation dose required to obtain a digital lateral cephalogram capable of being analysed by an on‐screen method within an acceptable degree of clinical error. To survey hospital based orthodontic departments in the West Midlands and use the gathered information to estimate what effective dose patients are being exposed to from lateral cephalometric exposures. RESULTS: Using the mean of each of the 10 recruited clinicians’ cephalometric measurements with 95% confidence intervals for the mean defined, clinically significant error appears not to have affected cephalometric measurements taken from any of the seven lateral cephalograms analysed down to a minimum effective radiation dose of 0.06μSv. The results of the hospital survey indicate units are exposing patients to an effective radiation dose of between 0.5μSv‐2.4μSv. CONCLUSIONS: A reduction in effective radiation dose and health risk may be possible to patients within the West Midlands during routine lateral cephalometric exposures.
