摘要：

Objectives. This in vitro study assessed the visualization quality of the periodontal ligament space in cone-beam computerized tomography (CBCT) compared with intraoral radiographs (CR). Study design. A phantom mimicking variable periodontal ligament spaces (0-0.42 mm) was radiographed using CBCT and CR. Fifteen datasets of each modality were randomly mixed and presented twice to 19 experienced examiners and once to 19 inexperienced examiners. Results. Zero-millimeter gaps were recognized in 84.4% of CBCT and in 81.6% of CR images. On CBCT scans, gaps of 0.19 mm were identified with an accuracy of 93%-100% compared with 70.2%-81.7% using CR. Experienced examiners recognized gaps of >= 0.19 mm on CBCT repeatedly with nearly 100% accuracy. Conclusion. Compared with CR, CBCT provides better visualization of simulated periodontal ligament space in this phantom. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010; 109: e95-e101)
