牙颌面锥形束CT与曲面体层X线检查对颌骨牙骨质瘤样病变诊断价值的比较研究

Comparative Studies of Diagnostic Evaluation of the Maxillary and Mandibular Cementoma Using Cone Beam Computerized Tomography Compared with Panoramic Radiography

目的:比较牙颌面专用CBCT与曲面体层对颌骨牙骨质瘤的诊断价值。方法:对3例发生于上下颌骨中的牙骨质瘤患者,分别选用曲面体层和CBCT检查,并将检查结果进行比较分析,判断相互之间的一致性和差异性。结果:3例上下颌骨内牙骨质瘤病变,在曲面体层上均有显示,但CBCT检查可以在矢状位、冠状位和横断面上以多个层面准确地反映病变的位置及骨质破坏的情况。结论:CBCT在对上下颌骨牙骨质瘤的诊断较曲面体层更为有价值。

Objective： To assess the osseous lesions of the maxillary and mandibular cementoma by dental cone beam computerized tomography （CBCT） and to compare it with panoramic radiography. Methods： Three patients with the maxillary and mandibular cementoma had undergone panoramic radiographic and dental come beam com- puterized tomographic examinations. The results were compared and the accuracy with CBCT and panoramic radio- graphy was assessed. Results： Panoramic radiography showed sizes and scopes of the lesions in the maxilla and man- dible. Cone beam computerized tomography reproduced multiple images including axial, coronal and sagittal planes of the lesions. Cone beam computerized tomography also provided a complete radiographic investigation of the ce- mentoma in the maxilla and mandible. Conclusion： Cone beam computerized tomography is one of the best choices of imaging diagnosis of cementoma in the maxilla and mandible.
