Radiográficamente se observa la formación incompleta de la raíz, las paredes del conducto radicular delgadas, y una extensa lesión periapical. Se realizó el desbridamiento químico-mecánico con limas K y se ejecutó la desinfección del conducto radicular con clorhexidina al 2%. El conducto se deja medicado con hidróxido de calcio (Vitapex®), el cual se reemplaza periódicamente con dicho material hasta los nueve meses, finalmente se obtura con Biodentine®. Se da seguimiento al caso a través de cuatro años, pasando por blanqueamiento interno, carilla de resina hasta llegar a poste intra radicular con corona completa de porcelana en lo concerniente al aspecto estético. En cuanto a la lesión periapical de gran tamaño, se llega a observar por medio de tomografías, disminución de la lesión al mínimo y genera cicatrización ósea. En relación con la observación clínica hay desaparición de la fístula y ausencia de sintomatología.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract 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.]]></p></abstract>
