Bases rationnelles de la reprise en endodontie. Faut-il être "à l'apex" pour avoir la paix en endodontie?

Any endodontic treatment showing a symptomatology should be retreated or corrected. Should we start the asymptomatic treatments over again when the x-ray does not show a filling that is complete, hermetically sealed, biological and under control? When the case arises, the decision to resume the treatment will depend on the state of the crown restoration: should it be redone for any reason? 1. When the crown filling does not need to be removed and redone, watchful waiting is recommended. 2. When the crown filling is deficient, and has to be redone, it would be advisable to resume or try to resume all the canal treatments that are not hermetically sealed, when an opening to the canal has to be worked out. Several experiences show that the rate of success of endodontic treatments that have been resumed is lower than that of endodontic treatments that have been carried out for the first time. Should radiographically inadequate but asymptomatic endodontic treatments not be resumed, it would result in problems only in a very small number of cases, as long as the state of intracanal balance is not broken.
