The conventional intraoral radiographic examination has its greatest value in the
detection of proximal carious lesions that are not easily detectable by careful and
thorough clinical examination.
With the advent of low cost, high performance computer, it became possible to
explore the use of digital image processing techniques on routine dental X-ray images.
Digital imaging technique can be applied to automatic analysis of radiographic image
and image processing for the evaluation of dental implants. computer aided image
interpretation to the diagnosis of periapical bone lesions, caries, and alveolar bone
changes.
Dove and McDavid had already studied whether computer image processing could
improve the diagnostic accuracy for the proximal caries. Wenzel, et al also reprorted
that the RVG performed more accurate caries diagnosis.
Generally speaking, the image processing can enhance the brightness, contrast, and
detail of image These facts can be merits of digital images over film images. The aim
of present investigation is to suggest economical hybrid system using personal computer
and to compare the periapical radiographs and their displayed digital images for proximal
dental caries detection.
