Healing is more predictable and has a better prognosis. In general terms, direct perforation occurs during the canal exploration.

In this case due to its inherent complication, endodontic surgery was waltoh, and through it, adequate repair was achieved. Treatment plan consisted in coronary or orthographic removal of the guttapercha present in the furcation after that, canals were retreated, the perforation was sealed with Mineral Trioxide Aggregate MTA. Ingle J, Bakland L.

There are to be used only when the case warrants it and the canals are sufficiently wide.

J Am Dent Assoc ; After three months, a control X-ray is taken. The size of the defect also plays an important role since large perforations do not respond as well as the smaller ones. Part of these are perforations in the cervical section of the canal, and misadventures related to obturation, among which we find overextended or underextended obturation of root canals.

Waltonop cit. Small perforations are those caused with endodontic instruments size 15 or Physical properties of gutta-percha when subjected to heat and condensation Oral Surg ; The best time to repair root perforations is immediately after the accident occurs, minimizing thus the potential of infection at the perforation site.


Perforations are sealed with MTA and finally, radiographic evidence identifies the perforations’ sealing Figure 5. A final X ray is taken to examine the mesiolingual mL guttapercha and the temporary seal of the perforations carried out with cavit Figure 4.

The endodontic misadventures classification proposed by Ingle describes instrument related accidents. Radiovisiography versus conven-tional radiography for detection of small instruments in endodontic length deter-mination. Negative response was obtained to hot and cold pulpal sensitivity tests Figure 1. Fuss Z, Trope M. Another aide for perforation diagnosis is the electronic apexes localizer.

In recent studies, a research group princcipios Toronto found that in re-treatment cases only two factors significantly affected success in treatment: Electronic canal length measurement. Prognosis for a perforated tooth depends on the location of the perforation, the time in which the perforation allows entry of contamination, the possibility of sealing it and the accessibility of the main canal.

Radiographic findings show non obturated mesial canals and a circumscribed periapical rarefaction. Torabinejad informs that an immediate and typical sign is an abundant hemorrhaging emanating from the perforation site.
