Room for improvement? The accuracy of dental practitioners who diagnose bony pathoses with radiographs.

OBJECTIVES

The impact of any effort aimed at improving diagnostic accuracy by improving clinical decision making in diagnostic radiology will be limited by the ability of the clinician to correctly recognize the presence of abnormalities on radiographs. We carried out a study designed to examine whether dentists are able to correctly identify various kinds of periapical bone lesions visible on intraoral radiographs and diagnose their pathologic nature.

STUDY DESIGN

General dental practitioners (n = 98) assessed 32 radiographs that showed either normal bone (10) or one abnormality (22) in the periapical bone. The "gold standard" for pathosis was histopathologic analysis. The dentists were asked to judge for the presence of an abnormality and to decide whether an active pathologic process was present.

RESULTS

On average dentists identified 81% of all visible abnormalities correctly. Subsequently, they diagnosed 59% of all the pathologic cases correctly. Dentists, however, incorrectly identified 55% lesions on radiographs when experts had stated that no abnormality was visible.

CONCLUSION

There is room for improvement of diagnostic accuracy of bony pathology.
