Radiographic outcome in PRF-treated permanent maxillary right central incisor: (A) Tooth showing incompletely developed root with wide and open apex, thin dentinal walls, and wide root canal space with periapical radiolucency; (B) At third month follow-up, tooth showing slight elongation in the root with accelerated closure of the apex and resolution in periapical radiolucency; (C) At the sixth month follow-up, tooth showed marked increase in the root length, obliteration of the root canal space, and excellent closure of the root apex with normal periapical anatomy; (D) At the 12th month follow-up, PRF-treated tooth exhibited excellent root lengthening, complete closure of the apex with normal periradicular architecture, thickened dentinal walls, and narrowing of the root canal space

On periapical radiographic examination, both teeth exhibited an incompletely developed root with thin dentinal walls and wide open apex (Figs 1A and 2A). At 6 months, on radiographic examination, the PRF-treated tooth showed accelerated root growth with complete closure of the apex (Figs 1B and C), whereas in tooth treated with blood clot the apex was found open (Fig. 2B). At 12-month examination, the PRF-treated tooth revealed accelerated root end growth, enhanced thick dentinal walls with narrowing of the canal space, faster closure of the apex, and normal periradicular architecture (Fig. 1D) as compared to the tooth treated with blood clot Fig. 2C).
Radiographic outcome in blood clot-mediated revascularization done in permanent maxillary left central incisor: (A) Tooth showing incompletely formed root with wide, open apex, and thin root dentinal walls, wide root canal space, and widened periodontal ligament space; (B) At the sixth month follow-up, apex still found open; (C) At 12th month follow-up, blood clot-treated tooth exhibited continued root elongation and favorable closure of the apex with periradicular architecture and slightly thickened root dentinal walls

On periapical radiographic examination, both teeth exhibited an incompletely developed root with thin dentinal walls and wide open apex (Figs 1A and 2A).

In the right lateral incisor, the PRF used was prepared from the autologous blood by centrifugation method 10 minutes prior to the procedure (Fig. 3).
