Evaluation of near-infrared digital imaging transillumination compared with bitewing radiography for proximal caries detection in children.

Background: Limitations in traditional caries detection tools have driven the development of alternatives methods, focused on the early lesion detection such as near-infrared digital imaging transillumination (NIDIT).

Aim: The aim of this study was to evaluate the performance of NIDIT compared with bitewing radiography (BWR) in the detection of interproximal carious lesions in children.

Design: A retrospective audit of data from children who had NIDIT, BWR and intraoral photographs was conducted.
