Objective: To determine if the accuracy of identifying interproximal carious lesions on bitewing radiographs depends on the level of secondary illumination.
Methods: Fourteen dentists examined bitewing radiographs of simulated interproximal lesions on dentition phantoms in conditions of maximal secondary illumination (the light condition) and minimal secondary illumination (the dark condition).
Results: There was no significant difference (p = 0.07) in the accuracy of identifying simulated interproximal carious lesions on bitewing radiographs in the light mean accuracy (72% ± 12%) and dark (75% ± 12%) conditions.
Clinical Significance: Examining bitewing radiographs on a viewbox located in the operatory is adequate for accurately identifying interproximal carious lesions.
