Introduction:
Various intraoral digital radiographic systems are available as an alternative to film-based radiography. Recent rapid progress in the field of digital radiography offers the possibility of image processing and manipulation. Pseudocolor filter is one of the tools of digital systems. The aim of this study was to compare diagnostic accuracy of proximal caries in black and white and colorized images.
Materials and methods:
In this in vitro study, forty extracted premolar were selected and mounted in acrylic blocks. The teeth were radiographed with complementary metal-oxide semiconductor (CMOS) digital sensor. Two observers evaluated the images with and without application of the pseudocolor tool. The teeth were sectioned for histological determination of the lesion. The diagnostic accuracy of each method was assessed by means of ROC analysis.
Results:
There were no significant differences between the black and white and colored mode of images (P = 0.973). There were no significant differences between observers.
Conclusion:
Color mode of digital images can be used for proximal caries detection.
