Abstract: Root fracture often occurs during extraction of impacted mandibular third molars. The fractured root is difficult to be removed, especially in the mandibular canal, and even be pushed to the deeper place, which might lead to or aggravate the inferior alveolar nerve damage. This paper reported a case to remove the fractured root of impacted mandibular third molars, in the mandibular canal.
