Research output: Contribution to journalArticlepeer-review


Dental clinicians were asked to distinguish differences in radiographic detail between complete mouth surveys taken with the use of D- and E-speed films. In complete mouth surveys consisting of one half D-speed and one half E-speed films, clinicians could not correctly identify the half of the survey taken with D-speed film 55% of the time. When asked to distinguish surveys consisting entirely of either D- or E-speed films, evaluators could not distinguish D-speed film surveys from E-speed film surveys 42.7% of the time. E-speed film produces diagnostically acceptable radiographs similar in quality to those of D-speed film with the added advantage of an approximate 50% reduction in patient exposure.
