case_images: A regular clinical and radiological follow-up was carried out to check the vitality of 21 (Figure 2).
case_images: 6-month follow-up radiograph: a radiolucent periapical lesion adjacent to 21. The negative response to the cold test confirms pulp necrosis.

case_images: Three months after performing revascularization treatment, visible root edification was observed (Figure 5).

case_images: Concerning 11, a renewal of the calcium hydroxide was carried out once the material has been absorbed (Figure 6).
case_images: 24-month follow-up radiograph of 11: an apical barrier was formed easily crossable with a file.
