An in vitro study was performed to detect occlusal caries lesions of extracted permanent human molars by electrical conductance measurement with the Ortek ECD™ electronic device, and each tooth was sectioned and biopsied to validate and evaluate results.


 Electrical conductance was measured in pits and fissures of carious and non-carious permanent molars with an Ortek ECD.  Subject to in vivo clinical support, the Ortek ECD is likely to prove to be the best method for detection and evaluation of early occlusal caries.
