Comparison of Dexis CariVu And Bitewing Radiography In Detecting Interproximal Caries In Permanent Teeth

Abstract: Purpose: To evaluate the accuracy of the DEXIS CariVuTM (DEXIS, Inc, Bioggion, Switzerland) device in detecting interproximal carious lesions in comparison to standard bitewing radiographs. Methods: Bitewing radiographs and CariVuTM images of interproximal surfaces were obtained from patients at the University of Illinois (UIC) Department of Pediatric Dentistry. Twenty-six residents and faculty of UIC Pediatric Dentistry Department completed questionnaires to assess the depth of caries lesions. Results: The bitewing radiograph showed higher accuracy in the rating of no caries and incipient caries, while the CariVuTM was more accurate in the rating of caries reaching the DEJ. CariVuTM is equally as sensitive in detecting if there is any caries as bitewing radiograph and is more sensitive in the detection of caries reaching the DEJ. The bitewing being more valid that the CariVuTM in for rater validity. Conclusions: DEXIS CariVuTM is an inferior device in the detection of no caries and incipient caries in that it leads to over-diagnosis of the severity of the caries lesions. However, the DEXIS CariVuTM can be used as an adjunct in the monitoring of caries progression due to lack of radiation and to be used for high caries risk patients.
