Abstract
The article presents a study regarding the comparison of the E-speed with D-speed radiographic films to examine the relationship of lesion cavitation and radiographic depth of the interproximal carious lesions. It is reported that ninety-nine permanent molars and premolars which were extracted for periodontal or orthodontic reasons were used for the study. The teeth were prepared by separating into groups of three and then positioning a group into a block of modeling clay for radiographic examination. The statistical tests were completed to assess the radiographic scores and from the macroscopic research, 41 surfaces were determined to be cavitated and 10 surfaces were found to exhibit some cavitation. The study demonstrated that E-speed may be used without comprising diagnostic imaging.
