Image Processing Techniques used for Dental X-Ray Image Analysys 3
Digital image processing can provide a useful contribution to the diagnostic process. Their procedure
was able to rank series of artificial periodontal bone lesions as accurate as experienced clinicians.
Comparison of data from clinical inspection of lesions during surgery and quantitative result of the digitized
procedure shows that the latter produced reliable information on the lesion size. Dental caries can be
