摘　　要：将锥形束CT(cone-beam computed tomography,CBCT)应用于口腔部位的三维成像,是近年来的研究热点。牙根纵裂是指发生在牙根的纵裂,未波及牙冠。本文通过CBCT明确诊断罕见左下中切牙牙根纵裂1例。与二维X线根尖片相比,CBCT扫描对牙折裂的诊断具有更高的准确度,具有重要的临床应用价值。The use of cone-beam computed tomography （CBCT） in stomatology was a hot spot in recent years, both to CT researchers and dentists. Vertical root fracture was the fracture occurring in root which didn＇t spread to the crown. This paper showed how to use CBCT to diagnose a vertical root fracture occurring in incisor correctly. Compared with conventional periapical film, CBCT was more accurate in diagnosing root fracture and had higher clinical application value.Supported by Science and Technology Program of Shandong University （Jl2LK57）.
