suspicious occlusal carious lesion (SOCL) can be defined as a lesion with no
cavitation and no radiographic radiolucency but for which caries is suspected.
The authors evaluated whether using a device changed the percentage of SOCLs
that were opened surgically and, among those SOCLs that were opened, the
proportion that had penetrated into dentin. Eighty-two dentists participated. In
phase 1 of the study, dentists identified approximately 20 SOCLs, obtained
patient consent, and recorded information about the lesion, treatment or
treatments, and depth, if opened. Dentists were then randomly assigned into 1 of
3 groups: no device, DIAGNOdent (KaVo), and Spectra (Air Techniques). In phase
2, dentists enrolled approximately 20 additional patients and recorded the same
phase 1 information while using the assigned device to help make their treatment
decisions. A mixed-model logistic regression was used to determine any
differences after randomization in the proportion of lesions opened and, if
opened, the proportion of lesions that penetrated into dentin.
