Abstract
Objectives: This clinical study was performed to compare the accuracy of endodontists ’ assessment o f the sizes o f periapical radiolucencies using electronic imaging with the RVG® 32000 intraoral radiographic system and Ektaspeed film. Methods: Following Institutions Review Board approval and informed consent, presurgical images were made both with the RVG® 32000 and Ektaspeed film for periapical lesions in 12 consecutive patients requiring endodontic surgery. Actual lesion size was determined by making impressions with Ethicon® bone wax at the time of surgery. A panel o f five endodontists reached consensus in estimation of the superior- inferior and mesio-distal dimensions of the periapical radiolucencies from the presurgical images, separately and independently for two modalities.
Results: Lesion dimension estimates were significantly different between images made with the RVG® 32000 Ektaspeed film. There was a much greater deviation from the measured actual values for estimates using film radiographs than for those for the RVG® 32000 images. Generally, there was an over-estimation o f lesion size with film, and a slight under-estimation with RVG® 32000 images. Conclusions: Digital intraoral imaging with the RVG® 32000 offers
potential advantages over conventional radiography in permitting
endodontists on average to more accurately estimate the size of periapical radiolucencies.
