The identification of the culprit lesion in apical periodontitis is often difficult due to the only limited performance of X-ray based techniques. MRI was applied in 30 patients and the results were qualitatively and quantitatively compared with cone beam CT images. MRI appears to reflect the actual size of the lesion much better than X-ray images and hereby an improvement of identification of the apical periodontitis can be achieved.
