Prior to participating in Phase 2, each dentist received approximately 2 hours of hands-on familiarization with the DIFOTI equipment.
A comparison of the consensus results for all examiners determined that the sensitivity for DIFOTI was 0.
Experimental use of DIFOTI as a diagnostic tool also resulted in a specificity value of 1.
DIFOTI has shown promise in the detection of interproximal, occlusal, and smooth surface carious lesions.
In this review DIFOTI was referred to as a "diagnostic instrument for early and reliable detection of caries without the need for ionizing radiation.
Approximately 2 weeks later each of the dentists served as examiners in this study and attempted to diagnose caries in both conventional radiographic images and DIFOTI images.
Clearly the results of the current study may reflect errors due to both the inexperience of the examiners in caries diagnosis and possible inexperience in interpreting DIFOTI images.
The DIFOTI technology can show subtle surface changes associated with potentially demineralized tooth surfaces.
DIFOTI can be a useful diagnostic adjunct, particularly when used to confirm the absence of disease (specificity).
Such training will allow the dentist to properly handle the DIFOTI handpiece to expose all potential carious surfaces and to properly interpret DIFOTI images.
The DIFOTI technology may be most useful in identifying demineralized areas of tooth structure and monitoring the results of remineralization therapy.
