[Root canal therapy opportunity in replanted teeth due to injury.].
OBJECTIVE
To investigate the opportunity of different root canal therapies in replantation of tooth due to injury.


METHODS
49 cases with teeth luxation were randomly divided into three groups. In group A, the pulp was removed before replanted, and calcium hydroxide was filled in root canals and condensated routinely after half a year. In group B, the pulp was removed one week after being replanted. In group C, the pulp was removed until pulp disease.


RESULTS
The effect of group A(81.25%) and B (94.44%) was better than group C (53.33%), P<0.05. And the effect of group A and B was similar.


CONCLUSIONS
It's an ideal method to replant luxated tooth within 3 hours with removal of pulp tissue, root canal filling with calcium hydroxide one week after replantation of tooth and condensated routine root canal therapy after half a year.
