The immediate post-operative period was uneventful (Figure 1a). At six-month follow-up, there were no signs of necrosis or mobility; however, the patient disappeared and returned to our service after five years (Figure 1b). At a five-year post-trauma evaluation, total apexification, complete PCC and yellow discoloration of the dental crown were observed in both central incisors, with an inconclusive response to pulp tests (Figure 1c).

However, at eight years post-trauma, a radiographically visible apical lesion was diagnosed, and the tooth did not respond to pulp tests and had light sensitivity to percussion (Figure 2a). Paulo, Brazil) were used to cut and scrape the bone to access the root apical area of tooth 11 (Figure 2b). Periapical curettage was performed in order to remove granulation tissue (Figures 2bd).

In the six-month follow-up, a periapical radiograph showed a slight radiolucency consistent with scar tissue (Figure 3a). At 53 months, no apical lesions, root resorption or bone loss were observed (Figure 3b).
