Summary: | Objectives: To compare and analyze the perceived clarity and
diagnostic value of Conventional periapical Radiographs (CRs)
with those of their Digitized Periapical Images (DIs) and Processed
Digitized Periapical Images (PDIs) counterparts.
Material and Methods: Forty two intraoral periapical radiographs
of patients with clinically suspected periapical pathosis were
made to constitute the group of CRs. These were photographed
by using a Canon Power Shot SD500 (7.1 Megapixel) digital
camera and the unaltered images were transferred to a computer
laptop, to form the group of DIs. Subsequently, the contrast
and brightness of these images were modified to represent the
group of PDIs. Two experienced oral radiologists independently
evaluated 5 specific apical and periapical region parameters of
all the 42 CRs, DIs and PDIs for perceived image quality and
diagnostic value and graded them on a three point grading scale.
Conventional radiographs served as the control. Data were
analyzed by using paired t-test and Kappa analysis.
Results: The clarity and diagnostic quality of the PDIs were
statistically significant as compared to those of their conventional
counterparts. In comparison, the DIs group fared badly, with
deterioration of the image quality. The interobserver agreement
was good and all the results were statistically significant.
Conclusion: Indirectly digitizing the radiographs by employing a
digital camera and further digitally processing the images resulted
in an improvement in their perceived clarity and they enhanced
their diagnostic properties. |
