The purpose of this experiment was to evaluate radiographic interpretation of various
sized 60 periapical and 60 cancellous lesions in 10 mandibular sections of 5 dogs
according to kVp (65, 70, 75, 80 and 85 kVp).
The results were as follows ;
The change of kilovoltage within 65kVp-85kVp range did not have influence on the
radio-graphic interpretation of the same-sized bony defects at the constant radiographic
density(>0.05).
When the bony defects were less than the size of No. 2 round bur, radiographic
interpretation of bony defects prepared with No. 2 round bur was easier than those
prepared with No. 1 round bur at 80-85kVp in periapical region (p<0.05). However, in
cancellous bone, this radiographic interpretation was easier at 65-75kVp (p<0.05).
There were significant differences in the radiographic interpretation between the
defects confined only to the cancellous bone and the defects involved in the compact
bone (p<0.05). However there were no significant differences between the defects
confined only to the cancellous bone and the defects involved in Junctional area of
cancellous and compact bone (p>0.05).
From the results of densitometric analysis, there was a difference in densitometric
measurements at the same radiographic interpretation scores, and aluminum equivalent
differences of 0.15-1.66§® thickness were needed for radiographic interpretation.
