title: Are Carious Lesions in Previously Sealed Occlusal Surfaces Detected as well on Colour Photographs as by Visual Clinical Examination?
abstract: OBJECTIVE
  To compare the level of agreement between carious lesion assessments according to the visual clinical examination and the colour photograph methods.
  
  
  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.
