The tooth was not tender on percussion, had a positive response to pulp sensibility test with a lingering pain (Roeko Endo-Frost, Coltene, Langenau, Germany) and intraoral periapical radiograph (IOPA) revealed no periapical lesion associated [Figure 1a]. Hemostasis was achieved within 5 min using saline-soaked cotton pellets, after which a small piece of PRF was used to cover the pulpal wound [Figure 1b and c] and a 2-mm thick layer of biodentin [Figure 1d] was placed over it, followed by composite restoration [Figure 1e].
(a) A 6-month follow-up radiograph showing a radiolucent lesion in the coronal third of the mesial root and radiolucency in the periapical area, (b-d) CBCT confirming a nonperforating internal root resorption associated with the coronal third of the mesiolingual canal of the mesial root and periapical radiolucency associated with both the root

Figure 2a. For the confirmation whether it is an internal or an external root resorption, a cone-beam computed tomography (CBCT) (4 x 4 fields of view sectional scan settings in Veraviewepocs three dimensional) was advised for the same, after which it was confirmed that it was nonperforating IRR associated with the coronal third of the mesiolingual canal of the mesial root [Figure 2b-d]. Furthermore, there was periapical radiolucency associated with both the roots.

The internal resorption was seen clearly under magnification [Figure 3a]. Obturation was done after 14 days, and the resorption defect was restored with Biodentine [Figure 3b and c]. Composite resin was then placed as a postendodontic restoration [Figure 3d], and a 6-month [Figure 3e] and 1-year follow-up was taken [Figure 4].
