| Abstract |
|
Local anesthesia is routine procedure in dental practices and has several complication. One of them, needle fracture is not uncommon in past, but rare in recent. The number of cases reported in the literature of broken needle in local anesthetic procedure has shown a marked decrease since the use of disposable spiral-constructed dental needle began. This complication results from lack of patient cooperation, inaccurate anesthetic technique, sudden movement of patient, error in the manufacturing procedure, use of short needle, and bending before use. Most common site is pterygomandibular space during inf. alveolar nerve block. In two patients, we removed broken needles under general anesthesia without complication. So we report cases with review of literatures. |
