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.
