The agar-replica technique for dental caries diagnosis. Has its time arrived?

The agar-replica technique of Bahn et al is described. This caries-diagnostic technique detects the site of lactobacillus infection on the teeth. Evidence and logic indicate that this technique is more accurate than current caries-diagnostic methods. The method appears to answer the recent call for diagnostic methods which identify the more subtle expression of the disease, and it helps classify lesions into categories keyed to different treatment strategies.
