Abstract

The purpose of this study was to elucidate the imaging characteristics of the gubernaculum tracts in successional teeth related to fused deciduous teeth on computed tomography. The imaging findings of 15 gubernaculum tracts in successional teeth related to fused deciduous teeth were retrospectively analyzed using cone-beam computed tomography or multidetector computed tomography. In cases without a congenitally defected successor, the two gubernaculum tracts of two successional teeth related to fused deciduous teeth were fused into one. Gubernaculum tracts (GTs) in mesial successors were vertical, but in distal successors they were inclined to mesial. The major abnormalities of the successional teeth related to fused deciduous teeth were delayed eruption and delayed formation. No inclined mesial successors were found, whereas most of the distal successors were inclined to mesial along with the inclined GT. The gubernaculum tracts of successors with a congenital defect of the other successors were vertical, and such successors had no abnormalities. The present study showed the imaging characteristics of gubernaculum tracts in successional teeth related to fused deciduous teeth. The abnormal eruption of successional teeth related to fused deciduous teeth may be associated with the characteristics of their gubernaculum tracts.

乳牙融合牙相关连续牙管束的计算机断层成像特征

本研究的目的是阐明与乳牙融合相关的连续牙的骨束在计算机断层扫描上的成像特征。回顾性分析了融合乳牙相关连续牙的15个乳带束的影像学表现。在没有先天性缺陷继位者的情况下，将与融合乳牙相关的两个连续牙齿的两个管束融合为一个。近端后继者掌骨束垂直，远端后继者掌骨束向近端倾斜。乳牙融合后继发牙的主要异常是延迟出牙和延迟形成。未见近中继位者倾斜，远中继位者多伴近中继位者倾斜。其他继位者先天性缺陷的继位者管束呈垂直，未见异常。本研究显示了乳牙融合后连续牙的绒毛束的影像学特征。乳牙融合后连续牙的异常萌出可能与其乳管束的特征有关。
