正畸医生在正畸治疗之前、期间和之后评估近远中牙根角度，以帮助建立正确的牙根位置。全景成像已用于这一目的，并是一个有价值的筛查工具的诊断和计划治疗正畸患者。锥束计算机断层扫描(CBCT)用于颅面复合体的成像，与传统的二维图像相比，创造了评估三维图像的机会。本项目的目的是通过治疗后的全景X线片和CBCT扫描来比较近远端牙根的角度。对35例正畸手术患者正畸治疗后的牙根近远端角度进行对比分析。全景图像用VixWin(Gendex Dental Systems，Des Plaines，Ill)测量，CBCT扫描用InvivoDental 3D(4.1版，圣何塞，圣何塞)测量。以牙合平面为参照线，测量上、下颌各牙近远中牙根角度。对于相关数据(具有非结构化协方差结构)，使用仅截距线性回归，对两个牙弓分别执行关于牙齿所有差异的平均向量是否为零的全局测试。两个牙弓的整体测试具有统计学意义(P<；0.001)，表明从全景图像和CBCT图像测量的牙根角度总体上存在差异。在全景和CBCT测量之间的平均差异中没有明显的模式。使用全景X线片评估近远中牙齿角度时应谨慎处理，并通过对牙列的全面临床检查加以加强。
Orthodontists assess mesiodistal root angulations before, during, and after orthodontic treatment as an aid in establishing proper root position. Panoramic imaging has been useful for this purpose and is a valuable screening tool in diagnosis and planning treatment of orthodontic patients. Cone-beam computed tomography (CBCT) for imaging of the craniofacial complex creates the opportunity to evaluate 3-dimensional images compared with traditional 2-dimensional images. The purpose of this project was to compare mesiodistal root angulations by using posttreatment panoramic radiographic images and CBCT scans. Mesiodistal root angulations from panoramic images and CBCT scans of 35 orthognathic surgery patients after orthodontic treatment were compared. The panoramic images were measured by using VixWin (Gendex Dental Systems, Des Plaines, Ill), and the CBCT scans by using InvivoDental 3D (version 4.1, Anatomage, San Jose, Calif). The mesiodistal root angulation of each maxillary and mandibular tooth was measured by using the occlusal plane as the reference line. With an intercept-only linear regression for correlated data (with an unstructured covariance structure), the global test of whether the mean vector of all differences for the teeth is zero was performed separately for the 2 arches. The global test for both arches was statistically significant (P<0.001), indicating an overall difference in root angulation between measurements from panoramic and CBCT images. There was no discernible pattern in the average differences between panoramic and CBCT measurements. The assessment of mesiodistal tooth angulation with panoramic radiography should be approached with caution and reinforced by a thorough clinical examination of the dentition.
