Use of cone-beam computed tomography to detect atypical vertical root fracture occurring at first left mandibular incisor:report of one case

Abstract

Abstract: 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.

Key words: Cone-beam CT, Root Fracture, MDCT
