Clinical extension of proximal carious lesions compared to bitewing radiographs using photostimulable phosphor plates (PSP).

Objectives: The aim of this study was to evaluate the use of digital bitewing radiographs using photostimulable phosphor (PSP) plates in the estimation of the true extension of proximal carious lesions.

Methods: The sample size was calculated to be 70 teeth. Adult patients with a minimum of one posterior tooth with primary proximal caries lesions were included.
