Clinical practice has shown that most avulsed teeth are replanted after an extra-alveolar time that compromises the prognosis of replantation. In cases of delayed replantation, the use of adequate media for storage and transportation of the avulsed teeth may improve this prognosis considerably. Difficulties inherent to accidental dental avulsion include the lack of immediate access to ideal storage media, which accentuates the importance of saliva as a viable and readily available option. The authors report the case of an accidentally avulsed permanent maxillary central incisor that was kept into the patient's oral cavity from the moment of trauma until its replantation, 90 min later. Three years of follow-up revealed absence of root resorption, ankylosis or abnormal mobility, which demonstrates the feasibility of keeping avulsed teeth in saliva, at least when more indicated storage media are not available immediately.
临床实践表明，大多数脱位牙在牙槽外停留一段时间后再植，这会影响再植的预后。在延迟再植的情况下，使用适当的介质储存和运输脱位牙可能会显著改善这种预后。意外牙脱位固有的困难包括无法立即获得理想的储存介质，这凸显了唾液作为一种可行且随时可用的选择的重要性。作者报告了一例意外脱位的上颌恒中切牙病例，该牙从受伤时刻起一直保存在患者口腔内，直到90分钟后再植。三年的随访显示没有牙根吸收、牙根粘连或异常松动，这表明将脱位牙保存在唾液中是可行的，至少在没有立即可用的更合适的储存介质时是可行的。
