ABSTRACT
Objective:
To analyze the pulpal prognosis of replanted permanent teeth in children and to examine the associated factors .Methods:
The samples consisted of 67 children with 81 avulsed perma-nent teeth treated in Peking University Hospital of Stomatology from 2000 to 2012 .Their clinical data of the replanted teeth were collected , and the follow-up period was no less than 12 months.The pulpal prognosis was classified as pulp necrosis and pulp non-necrosis .Results:
The replantation within 30 minutes after avulsion led to the most significant increase in pulpal healing (P<0.05).The dental pulp of 80% ( 4/5 ) young permanent teeth replanted within 30 minutes remained vital , while all the teeth replanted after 30 minutes developed pulp necrosis within 60 days after replantation .Conclusion:
The extra-alveolar period significantly affects the prognosis of pulp in immature permanent teeth after replanta-tion.When the extra-alveolar period is more than 30 minutes, the chance of pulp revascularization after replantation is very low , therefore pulp extirpation should be performed .
