1979年至1997年，58撕脱乳牙在新泻大学牙科医院儿科诊所治疗。其中，我们再植了四名患者的六颗撕脱门牙，并治疗了两名在其他牙科诊所再植的患者的两颗牙齿。结合临床资料、口腔照片及X线片，对患者的受伤年龄、受伤原因、牙齿保存情况、离再植时间及再植后的预后进行分析。2例患者的3颗牙齿保留到永久性继承者萌出，1例患者的1颗牙齿仍在观察中未拔除。3例患者的其余4颗牙虽然拔除，但未发现因再植引起的继发感染。以下原因被怀疑是四颗牙齿预后不良的原因。1颗撕脱牙再植后未立即固定。一颗再植的牙齿可能与牙槽窝不兼容。另外两颗牙的牙周重要组织可能在再植前已被切除。一般认为，乳牙再植不是一个好的选择。但从目前的研究结果来看，认为在撕脱乳牙条件适宜的情况下，再植是一种有效的方法。
Between 1979 and 1997, 58 avulsed primary teeth were treated at the Pedodontic Clinic of Niigata University Dental Hospital. Among these, we replanted six avulsed incisors of four patients and treated two teeth of two patients replanted at other dental clinics. Referring to the clinical records, oral photographs and radiographs, we examined the injury age, cause of injury, condition of tooth storage, length of time until replantation, and also the prognosis after replantation. Three teeth of two cases remained until eruption of their permanent successors, and one tooth of one case remained under observation without extraction. Although the other four teeth of three cases resulted in extraction, no secondary infection was detected due to replantation. The following reasons were suspected for the poor prognosis of the four teeth. One avulsed tooth was not fixed immediately after replantation. One replanted tooth might not have been compatible with the alveolar socket. In the other two teeth, the periodontal vital tissues might have been removed before replantation. It is generally suggested that replantation of primary teeth is not a good option. However, from the present results, it was considered that replantation can be an effectual method when the condition of the avulsed primary tooth is suitable.
