Decision-making tree for dental caries according to Nyvad and Fejerskov [1997] The status of tooth surface Sound Lesion
370 nm • 520 nm [Inspector Research Systems BV]
Diagnostic Method Surface R* ECM Occlusal 0.62, 0.82 Quantitative FOTI Approximal 0.87, 0.92 QLF Buccal/lingual 0.78, 0.86 Correlation between Test Outcome and Lesion Depth in Studies Published Since 1992 [Verdenschot et al., 1999] * Spearman rank correlation coefficient
QLF is more sensitive than ECM for measurements of shallow occlusal lesions • [Verdenschot & Angmar-Månsson, 2003] [Inspector Research Systems BV]
Laser system showed higher sensitivity and specificity than ECM [Lussi et al., 1998] [KaVo]
-(extracted teeth) QLF can improve early detection of secondary caries around amalgam restoration [Ando et al., 2004] -(artificial lesions) Composite resins and compomers increase, whereas amalgam, glass ionomer and Coltosol reduce fluorescence [Pretty et al., 2003] -(artificial lesions) Monitoring over time of the potential secondary caries lesion seem to be the most reasonable approach [González-Cabezas et al., 2003]
How about residual caries?
Decision-making tree for dental caries according to Nyvad and Fejerskov [1997] The status of tooth surface Sound Lesion Inactive (non-progressing) Active (progressing)
Arrested lesion DD 55
Dehydration for as little as 3 sec may be adequate to identify active early lesions in enamel [Stookey, 2004] FI Dehydration Time (seconds)
Decision-making tree for dental caries according to Nyvad and Fejerskov [1997] The status of tooth surface Sound Lesion Inactive (non-progressing) Active (progressing) Treatment decision Non-Operative Treatment Operative Treatment
True positive rate B Lower measurements: need of intervention A Positive measurements: monitor in time False positive rates
The ultimate goal of making a diagnosis is always to select the best possible treatment [Nyvad, 2004]
