Extrusions
For the 2 teeth with preoperative periapical overfilling of gutta-percha we obtained healing after retreatment. During the retreatment overfilling of gutta-percha that occurred in three cases, two teeth healed and one was healing. Among the teeth classified as failure, three are with extrusion of sealer. Among the teeth classified as healing four are with this kind of extrusion. The majority of teeth with sealer extrusion (21/28) are classified as healed. It’s accepted that it is better to avoid overfilling but a controlled overfilling („puff”) is not a predictor of failure.
Perforations
Perforations were long considered as major complications reducing the prognosis for survival of the tooth. Treated teeth from the Toronto Study have a better healing rate if the tooth is not perforated (86% versus 36%) [20]. These results are put in relation with the filling of these perforations material, namely, GIC cement. Since the use of MTA cement, the results are more predictable. In our study, all perforated teeth have recovered through the use of MTA cement and operative microscope. Thus, a perforated tooth may be kept on the arcade in so far as the perforation is accessible and its filling does not prevent access to the root canals (Fig. 5).
