on a dental radiograph, interproximal caries are typically seen at or just below (apical to):

what shape or configuration does the caries make as it progresses inward through the enamel of the tooth?

when caries reaches the DEJ, which direction does it spread to continue to the dentin?

what are the four interproximal carious lesions classified as?

caries that extends less than halfway through the thickness of the enamel:

which class is incipient caries and which structure(s) does it go through?

caries that extends more than halfway through the thickness of the enamel but does not involve the DEJ

moderate interproximal caries are which class and where are they seen?

caries that extends to or through the DEJ and into the dentin but does not extend through the dentin more than half the distance toward the pulp:

which class is advanced interproximal caries and which layer(s) are involved?

caries that extends through the enamel, dentin, and more than half the distance toward the pulp:

what class are severe interproximal caries and which layer(s) are involved?

when are occlusal caries actually seen on a radiograph?

what are the three classifications of occlusal caries?

which caries cannot be seen on a dental radiograph and must be detected clinically with an explorer?
