Abstract
Although automatic processing is becoming more widely available in general dental practice, there is little objective information regarding the quality of this type of processing. Thus a postal study was undertaken to compare manual and automatic processing using a questionnaire together with a standardised, pre-exposed test radiograph for routine processing. Analysis of variance showed significant differences between the manually processed, automatically processed and control test films, in respect of D Min (P < 0.001), test strip (P < 0.001), and step density values (P < 0.01) but not for D Max (P > 0.1). The manually processed test films generally had significantly less density than the automatically processed test films or control test films
