Management of unfavorable iatrogenic perforations during post placement using mineral trioxide aggregate: report of two cases. Rev. Estomatol. Herediana [online]. 2021, vol.31, n.4, pp.311-316.  Epub 05-Out-2021. ISSN 1019-4355.  http://dx.doi.org/10.20453/reh.v31i4.4100.

Two patients attended at the Endodontics Department to evaluate teeth 35 and 46. Both teeth had a history of post placement in a recent endodontic treatment in tooth 46, and 3 months ago in tooth 35, with evident large perforations in the middle third of their roots. In both cases, perforation sealing was recommended. The posts were removed and white MTA Angelus (Angelus, Londrina, PR, Brazil) was placed in the perforations of both cases. Finally, the root canals were obturated using the continuous wave technique. The 6-month, 2-year and 6-years follow-ups (tooth 35), and 3-month, 1-year and 3-year follow-ups (tooth 46) showed a favorable evolution. It can be concluded that the application of MTA in iatrogenic perforations promoted good results, allowing the maintenance of the teeth in function.
