In this case the doubt is whether enamel caries exists or not. Bacterial plaque control is indicated in these situations, based on oral and dental hygiene measures and topical fluor application. If the suspicion of caries results from high LF readings with normal VI findings, monitorization fundamentally should be carried out with LF. The detection of positive VI signs or increased LF readings during follow-up, potentially indicative of lesion progression, requires fissure aperture.
If caries is suspected on the basis of the VI findings, with normal LF results, the subsequent controls should be centered on VI. The detection of an increase in positive VI signs or increased LF readings during follow-up, potentially indicative of dentin involvement, requires fissure aperture.
