(a) An immature, maxillary right lateral incisor with open apex and large localized, well-defined periapical radiolucency in a 40-year-old male. (b) Six months after revascularization + PRP, apical pathology is reduced and apical narrowing is seen. (c) At 1-year follow-up, normal bony architecture around the entire root is reestablished. Note the narrowing of the apical third of the root canal.

Intraoral tracer periapical radiograph with a #30 gutta-percha point was exposed (Figure 1(a)). It revealed a blunderbuss root apex with thin lateral dentinal walls associated with a large periapical pathology measuring 1.5 x 1.5 cm2 (Figure 1(a)). Periapical healing, apical closure, root lengthening, and dentinal wall thickening were evident radiographically (Figure 1(c)).
