OBJECTIVES
The purpose of this study was to identify the spatial relationship and/or association between odontomas and the gubernaculum tract or the dental sac and the characteristic findings for radiographic diagnosis of odontomas.
STUDY DESIGN
The visualizations of the odontomas and the gubernaculum tract were retrospectively analyzed using cone beam computed tomography or multidetector computed tomography.
RESULTS
Most of odontomas were within the gubernaculum tract or dental sac of unerupted permanent teeth on computed tomography. In some odontomas, the gubernaculum tract existed as a well-defined low density tract extending from the top of odontomas on computed tomography.
CONCLUSIONS
A close spatial relationship and/or association between odontomas and the gubernaculum tract or dental sac on computed tomography may be used as one of the criteria for radiographic diagnosis of odontomas. Development of odontomas may be associated with the gubernaculum tract or dental sac of unerupted permanent teeth.
目的
本研究的目的是确定牙瘤与 gubernaculum 束或牙囊之间的空间关系和/或关联，以及牙瘤的放射学诊断特征。
研究设计
使用锥形束计算机断层扫描或多排探测器计算机断层扫描对牙瘤和 gubernaculum 束进行回顾性分析。
结果
在计算机断层扫描中，大多数牙瘤位于未萌出恒牙的 gubernaculum 束或牙囊内。在一些牙瘤中，gubernaculum 束在计算机断层扫描中表现为从牙瘤顶部延伸的界限清晰的低密度束。
结论
牙瘤与 gubernaculum 束或牙囊在计算机断层扫描上的密切空间关系和/或关联可作为牙瘤放射学诊断的标准之一。牙瘤的发生可能与未萌出恒牙的 gubernaculum 束或牙囊有关。
