title: Comparison between a laser fluorescence device and visual examination in the detection of occlusal caries in children.
abstract: Occlusal surfaces of molars are especially susceptible to the development of caries due to the features, such as pits and deep fissures, of their anatomical structure.
  
  
  OBJECTIVE
  To evaluate the efficiency of DIAGNOdent laser fluorescence measurements in comparison with visual examination for occlusal caries detection for first permanent molars in children.
  
  
  METHODS
  The study involved 156 permanent molar teeth in 40 children aged 7-12 years. A relatively new technology, the fluorescence laser DIAGNOdent pen, was used for detecting and diagnosing caries on the occlusal surfaces of molars. The visual examination of fissures was based on the Ekstrand classification system.
  
  
  RESULTS
  The results showed a strong relationship between examination with the DIAGNOdent and visual inspection. DIAGNOdent's sensitivity and specificity were 97% and 52%, respectively, indicating that the laser fluorescence DIAGNOdent pen is a reproducible and accurate diagnostic tool that may be very helpful in conjunction with visual examination in the detection of occlusal caries in permanent molars in children.
