The Effectiveness of an Intraoral Scanner With Near-infrared Imaging (Transillumination) Technology for the Detection of Proximal Caries

A total of 639 proximal surfaces (mesial-distal) of 22 volunteers without restoration of premolars and molars were examined. Results were scored for 4 different examination methods; intraoral examination by visual-tactile method (VTM), bitewing radiography (BWR), panoramic radiography (PR) and near-infrared imaging (NIRI). Scoring was made according to the type of lesion (0:no caries, 1:early enamel lesion(EEL), 2:lesion involving the dentin-enamel-junction (DEJ). Data were analyzed with IBM-SPSS-V23. McNemar-Test was used for comparison between the methods. The Kappa Test was used to examine the agreement between two methods in categorical data, and the Fleiss-Kappa Test was used to assess the agreement between more than two methods. The analysis results are presented as frequency(percentage).The significance level was considered p<0.05.
