Basic ResearchAccuracy of Cone-Beam Computed Tomography and Periapical Radiography in Detecting Small Periapical Lesions
Section snippets
Materials and Methods
Six half-mandible block sections procured from the Department of Anatomy at Loma Linda University were dissected of all soft tissue. Roots with canal filling materials, posts, vertical root fractures, or detectable PA radiolucencies were discarded along with all non-native materials including restorations and implants. The remaining roots were carefully extracted. A dental operating microscope (G-6; Global Surgical Inc, St Louis, MO) was used to screen out for defects at the base of the socket.
Results
The 2 CBCT devices had higher specificities than PA radiography (0.754), with the specificity of the Morita (0.892) being slightly higher than that of Kodak (0.862) (Table 1).
The overall AUCs for Kodak, Morita, and PA radiography were 0.767, fair (95% CI, 0.743–0.792); 0.753, fair (95% CI, 0.728–0.779); and 0.584, fail/random guessing (95% CI, 0.554–0.615) (Table 2). For both CBCTs, the AUCs for all simulated lesion sizes were higher than the AUCs for each of the corresponding simulated lesion
Discussion
The values of specificity for both PA radiography and the 2 CBCT devices compare favorably with those reported by Stavroupoulous and Wenzel (13) in a pig jaw study. In contrast, Estrela et al (5) and Patel et al (12) reported much higher specificities for PA radiography. Aside from observer variability, a possible explanation for these differences is that Patel et al used only the distal root of the first mandibular molar where the surrounding cancellous bone is much thicker than for the
