The 37-year-old patient had a class III external resorption of the root of 13#.
The cbct showed a lesion of about 4mm in diameter, which vestibularly affected the root #13, just below the junction.
A coronal repositioning flap first at partial thickness then total thickness and finally a periosteal incision to mobilize the flap were performed. The anatomical papillae were disepithelized to allow the sliding of the surgical papillae.
After removing the granulation tissue as far as possible compatibly with maintaining the vitality of the tooth, the cavity was filled with Biodentine, a bioceramic, perfectly biocompatible cement based on synthetic tricalcium silicate which is a valid substitute for dentine itself. The control is at one year.
