Summary
Early proximal caries detection is improved with laser fluorescence devices (DIAGNOdent). DIAGNOdent shows higher accuracy than visual inspection and bitewing radiography for identifying early tooth decay.
Area of Science:
- Dentistry
- Diagnostic Imaging
- Caries Research
Background:
- Initial proximal caries presents diagnostic and therapeutic challenges.
- Conventional caries detection methods have limitations.
- Optical technologies offer advanced solutions for early caries detection.
Purpose of the Study:
- To compare the in vitro diagnostic accuracy of visual-tactile inspection, bitewing radiography, and laser fluorescence (DIAGNOdent pen) for early proximal caries detection.
Main Methods:
- Extracted human teeth (58 proximal surfaces) were examined using visual inspection, bitewing radiography, and DIAGNOdent (with and without proximal contact).
- Results were validated against a histological gold standard.
- Statistical analysis included ROC curves, sensitivity, specificity, and diagnostic accuracy at three demineralization thresholds.
Main Results:
- DIAGNOdent directly in the lesion demonstrated the highest diagnostic accuracy (89%-92.5% sensitivity, 81.29%-93% specificity).
- DIAGNOdent with proximal contact also showed high accuracy (88%-91% sensitivity, 79%-89% specificity).
- Bitewing radiography and visual inspection had lower diagnostic accuracy compared to DIAGNOdent.
Conclusions:
- Contemporary diagnostic devices like DIAGNOdent significantly enhance early proximal lesion detection.
- DIAGNOdent serves as a valuable adjunct, improving the accuracy of conventional caries detection methods.
