SURGICAL-TREATMENT OF A PERIRADICULAR LESION ON AN INVAGINATED MAXILLARY LATERAL INCISOR (DENS-IN-DENTE)

The complex anatomy of invaginated teeth make their root canal treatme nt difficult, Moreover, this treatment may compromise the future of th e tooth if it is destined to support a post-retained coronal restorati on, This case reports the successful surgical root canal treatment of an invaginated tooth using a retrograde filling with gutta-percha. Aft er surgical exposure of the root-end and cleaning of the root canal, t he gutta-percha was compacted in the root canal which had been coated previously with a zinc oxide-eugenol cement, The gutta-percha was then cold-burnished. Periapical radiographic examination after 1, 2, 3, 6 and 12 months showed periapical healing with osseous formation, This p rocedure, resulting in minimal loss of hard tissues, permitted subsequ ent restoration of the tooth.
