BACKGROUND
In this study, individuals with unilateral palatally shifted canines had cone beam computed tomography (CBCT) image palatally displaced canine (PDC) and non-PDC sides investigate the anatomy of their upper teeth adopting a "surface matching" approach.
PROCEDURES
The CBCT scans of an overall of 28 people with unilateral PDC were chosen. Every single tooth in research was broken down and turned into a three-dimensional structure utilizing identical research programs, which made it possible to quantify the total length of the tooth root.
RESULTS
Assessing the lateral incisor (LI) roots quantities and widths of the control category, non-PDC side, and PDC sides revealed statistically significant variations ( < 0.001).
CONCLUSIONS
Compared to contra-lateral LIs, LIs next to PDCs possess small roots. In addition, patients with unilateral PDCs had structural abnormalities between their canines and LIs.
背景
在本研究中，单侧腭向移位尖牙的个体采用“表面匹配”方法，利用锥形束计算机断层扫描（CBCT）图像对腭向移位尖牙（PDC）侧和非PDC侧的上颌牙齿解剖结构进行研究。
步骤
选取了总共28例单侧PDC患者的CBCT扫描图像。研究中的每颗牙齿都被分解，并使用相同的研究程序转化为三维结构，从而能够对牙根的总长度进行量化。
结果
评估对照类别、非PDC侧和PDC侧侧切牙（LI）的牙根数量和宽度，发现存在统计学上的显著差异（<0.001）。
结论
与对侧侧切牙相比，PDC旁的侧切牙牙根较小。此外，单侧PDC患者的尖牙和侧切牙之间存在结构异常。
