Independant study Buchgraber B, Allmer N, Städtler P. Abstract: CarieScan is a new tool to detect occlusal caries lesions under intact fissures using AC impedance measurements. The aim of this survey was to compare the accuracy of CarieScan in vivo with visual and radiological caries diagnosis. One dentist examined 76 teeth using visual and radiological criteria as well as using Carie Scan. The teeth were cleaned with toothbrush and water, isolated with cotton wool rolls and dried for 5 s. 3 measurements with CarieScan were taken at the same tooth and area. Bite-wings were taken and the occlusal surfaces were examined with the ICDAS method. There was a significant correlation between the clinical outcome and the CarieScan measurements (Spearman:p = 0.45). The agreement between the 3 measurements was fairly high (ICC = 0.73). There was no significant correlation between the CarieScan output and the x-ray results. CarieScan is appropriate to detect initial lesions and to monitor early non-cavitated lesions which are not visible on radiographs. However, in some cases CarieScan did not work correctly, so there is still room for improvements. |
