Digital Imaging Fiber-Optic Trans-Illumination, F-speed radiographic film and depth of approximal lesions

DIFOTI technology should not be used to decide between surgical or chemical treatment strategies based on lesion depth. We found that F-speed radiographic film was accurate in the approximating the depth of the lesion histologically. Ideally, the clinical decision whether to cut the tooth should be made based on cavitation rather than histologic lesion depth.
