title: [The effect of expertise on the interpretation of dental radiographic images].
abstract: A difference exists in the way novices and experts interpret dental radiographs. For education in dental radiology knowledge about the expert strategy is important. The aim of this study was to determine how novices and experts differ in the way they judge dental radiographs. Therefore 16 radiographs with different types of pathologies in the hard tissues were observed by 15 observers with three different levels of expertise. Based on their verbal reports the information content of the radiographs was determined for the different expertise levels. One radiograph with the same information content for all levels was observed by 8 novices and 8 experts. The eye movements of the observers were registered during the interpretation. Based on the results it is concluded that the experts make a more adequate selection of the stimulus material. Recommendations are given for the structure of the educational programme in dental radiology.
