摘要： 目的:观察同步辐射衍射增强CT对根管充填后离体牙的成像效果。方法:应用同步辐射衍射增强成像对10颗经根管预备和热牙胶充填的离体牙牙根进行成像,并进行CT重建。结果:可观察到主根管和侧支根管影像,并能清晰观察到根管充填后牙胶和根管封闭剂的充填区域,及充填缺陷如未被充填的空隙和气泡等情况。结论:同步辐射衍射增强CT适合观察和评价根管充填效果。

Abstract: Objective: To investigate the quality of root canal obturation using synchrotron radiation based diffraction enhanced imaging CT. Methods: Ten lower premolars were collected, and the root canals were prepared and obturated. All teeth were scanned with synchrotron radiation based diffraction enhanced imaging CT and reconstruction of the obturated root canals was performed. Results: Root canals and lateral canals were observed and interface voids and gaps around dentin were surveyed. Conclusion: Synchrotron radiation based diffraction enhanced imaging CT has the potential benefit on analyzing the effects of root canal obturation.

Key words: Root canal obturation , Synchrotron radiation , Diffraction enhanced imaging
