Proximal Caries Detection Accuracy Using Intra Oral Digital Bitewing Radiography and Conventional Intra oral Bitewing Radiography with Film

Background and Radiographs are essential for detecting proximal caries. The aim of this study was to compare proximal caries detection using intra oral bitewing with film and digital bitewing. Digital bitewing and conventional bitewing radiographs were taken from 100 extracted human teeth. Proximal caries depths in radiographs were scored by two oral and maxillofacial radiologists. Then the teeth were sectioned to evaluate and score the depth of caries lesions in proximal surfaces under microscope. Scores of radiographic and histopathologic assessments were compared using ROC curve analysis. The differences of sensitivity and specificity of two techniques were not statistically significant. Accuracy of both radiographic techniques was found to be similar in this study.
