Revascularization in Immature Permanent Teeth with Necrotic Pulp and Apical Pathology: Case Series

Figure 2

(a) Periapical radiograph image, 6 months after a trauma-induced subluxation of tooth 21, shows open apex of more than 2 mm, with periapical radiotranslucency. (b) Start of revascularization treatment of tooth 21, determination of working length. (c) Chamber sealed with MTA and wet cotton pellets, waiting for it to set hard. (d) Follow-up radiograph at 3 months, the periapical radiotranslucency at tooth 21 has disappeared. (e) Seven months after completion of revascularization therapy, dentinal wall thickening can be observed at 21, with the consequent narrowing of the apical foramen. (f) One year and 7 months after completion of revascularization treatment and compared with the periapical radiograph taken when revascularization treatment ended, there is a noticeable increase in root length, similar to the adjacent central incisor, thickening of the root walls, and a closed apex.
