In-Vivo Performance of the CarieScan Pro Device for Detection of Occlusal Dentine Lesions

Author(s): Anahita Jablonski-Momeni and Sarah Marie Christin Klein

Objective: The aim of this study wasto evaluate the in-vivo performance of the CarieScan Pro (CS) device based on AC Impedance Spectroscopy technology (ACIST) on occlusal surfaces. Subjects and Methods: The ethics committee approved thestudyandtheparticipantsgaveinformedconsent.Thestudyincluded144unrestoredpermanentmolarsfrom24patients.The occlusalsurfacesoftheteethwereexaminedvisuallyusingICDAScriteria.ThenCarieScanmeasurementswereperformed.The actualdepthofthelesionswasassessedusingradiographsand/orclinicallybyopeningthelesionwhenappropriate.Correlation between all methods was assessed using Spearman’s rank correlation coefficient (r𝑠). Sensitivity (SE) and specificity (SP) were calculated at the D3- (dentine caries) diagnostic threshold and the area under the ROC curve (AUC) was assessed. Results: SignificantpositivecorrelationwasfoundbetweenICDAS,CSmeasurementsandthereferencestandard(r𝑠0.37–0.72,P<0.0001). TheAUCforICDASandCSwere0.93and0.84,respectively.Sensitivity/specificityforICDASandCSwere72.0%/96.6%and 68.0%/90.8%,respectively.ComparisonoftheROCcurvesshowednosignificantdifferencebetweentheICDASandCarieScan Properformance(P=0.129).Conclusion:Bothmethodsshowedgooddiagnosticperformanceindetectionofdentinecarieson occlusalsurfaces.<
