Prognosis of replanted avulsed permanent incisors: A systematic review

The objective of this systematic review is to use the principles of evidence-based dentistry to evaluate clinically and radiographically the prognosis of replanted avulsed permanent incisors in the pediatric age group with an immature or mature apex having an extraoral dry time up to 60 min and a follow-up period of 24 months or more. The study inclusion criteria included case reports and case series published in English. Databases used for the search were PubMed, EBSCOhost, Google Scholar, and Cochrane from January 1, 2000 to September 30, 2017. In addition, hand search of dissertations and journals on pediatric dentistry related to the topic of interest was performed in the institutional library. Contact to authors and colleagues working on similar subjects in the field was made through e-mails. Based on the moderate level of evidence available to assess the prognosis of replanted avulsed permanent incisors by clinical and radiographic evaluation, it is fair to conclude that the prognosis of the replanted teeth was best when the extraoral dry time was <15 min and the tooth was stored in osmolality-balanced media such as Hank's balanced salt solution, saline, and milk. The immature teeth showed better prognosis than mature teeth.
