Purpose: To compare the level of agreement between carious lesion
assessments according to the visual clinical examination and the colour
Materials and Methods: Data on the presence of
enamel/dentin carious lesions in previously sealed occlusal surfaces in
first molars were obtained by two trained and calibrated examiners
through visual clinical examination and from colour photographs 4 years
after sealing. Kappa statistics were applied to calculate agreement
between assessment methods. Data analysis was performed using sign,
Bowker symmetry and McNemar's tests.
Results: The prevalence of
dentin carious lesions was very low. The kappa coefficients for
detecting enamel/dentin carious lesions using the two assessment methods
were 0.65 (CI: 0.56-0.74) for examiner 1 and 0.70 (CI: 0.62-0.78) for
examiner 2. Examiner 2 observed more enamel/dentin carious lesions on
colour photographs than did examiner 1 (p = 0.008). Sensitivity analyses
did not confirm this outcome.
Conclusions: There was no difference
in the detection of enamel/dentin carious lesions in previously sealed
occlusal surfaces using colour photographs vs visual clinical
examination. The colour photograph method is therefore equivalent to the
visual clinical examination in detecting enamel/dentin carious lesions.
More studies are required.
