BARZUNA, Mayid  e  PABON, Edgar. Non-surgical Therapeutics of large size periapical injury: Clinical case report. Odontología Vital [online]. 2020, n.32, pp.29-38. ISSN 1659-0775.

This report describes a clinical case involving a 21-year-old woman, who suffered dental trauma at age 6, compromising left tooth 2.1. On time she developed a large periapical injury in this area. Radiographically, incomplete root formation, thin walls of the root canal, and extensive periapical damage is clearly shown. Chemo- mechanical debridement was performed with K files and disinfection of the root canal using 2% chlorhexidine.

The root canal was left medicated with calcium hydroxide (Metapex), which was replaced periodically until 9 months. Finally, the root canal was completely sealed with Biodentine. The case had a follow up for over four years and concerning esthetical aspects, through this period of time an internal whitening, resin veneer, intra radicular post and complete crown were provided. Regarding the considerable periapical injury, tomography shows that it has been drastically reduced and generated bone healing. Clinical observations also show that the fistula and symptomatology disappeared.
