Abstract

Objective: The purpose of this study was to compare the effectiveness of detecting proximal carious lesions utilizing a new near-infrared transillumination (NIRTI) system (CariVu, Dexis) to traditional digital bitewing radiography (BWXR).

Materials and methods: Thirty patients received four posterior BWXRs and all premolars and molars were individually imaged with the NIRTI device. Sixty-seven proximal carious lesions were classified based on their depth into enamel or dentin for both BWXR and NIRTI images.

Results: The caries depth classification between the two systems were strongly correlated (rs = 0.66; Spearman range: 0.60-0.79 = strong) and significant (P < .001) with a median score of 3 for NIRTI and 2 for BWXR.

Conclusions: The new NIRTI system (CariVu) may serve as an adjunct to BWXR in the diagnosis of proximal caries.

Clinical significance: The NIRTI system could serve as an adjunct diagnostic system that could be used in high-caries risk programs where patients are closely monitored with regimented follow-up appointments. NIRTI could also be beneficial with pregnant or pediatric patients, and in situations where radiography may not be available such as remote humanitarian missions.

Keywords: adjunctive diagnosis; caries detection; digital radiography; near-infrared transillumination.
