Autologous platelet-rich-fibrin-induced revascularization sequelae: Two case reports

Figure 5 Four-year treatment outcome and re-treatment procedures for case #2 (tooth #14). Figure shows the condition of the tooth after 4 years. A: The 4 years periapical radiograph showing recurrent decay on the distal surface of the tooth underneath the composite restoration. Insert in A shows the extent of the decay and the pulp chamber prior to complete removal of the MTA coronal plug. Note that the periapical tissues appear healthy; B: Shows the pulp chamber after removal of residual MTA material taken using a Kaaps dental operating microscope (x 10, Original magnification). Insert in B shows location of orifices. Minimal traces of fragmented tissues were retrieved from the pulp chamber; C: Higher magnification of the first mesiobuccal canal (x 25, original magnification) shows diffuse calcification and an obliterated canal beyond this level; D: Immediate post-operative radiograph showing root canal filling with gutta percha till the level of canal obliteration for the 4 canals. The maximum length reached was 16 mm for the palatal canal, 14 mm for the first mesiobuccal canal and 3 mm for the distobuccal canal while only the canal orifice was negotiated for the second mesiobuccal canal.
