A 30-year-old male patient was referred to our clinic due to the detection of a reddish crown discoloration in his upper left central incisor which had lasted for three months (Figure 1A). Diagnostic periapical radiography demonstrated a large resorption defect in the tooth crown (Figure 1B), and cone-beam computed tomography (CBCT) with a higher diagnostic accuracy reconfirmed a large resorptive lesion in the tooth crown extending into the mid-root with probable pulpal involvement (Figure 1C-1G). The immediate postoperative periapical radiograph showed appropriate pulp capping as well as a suitable coronal restoration (Figure 1H); with the pink color of involved tooth changed to its original color (Figure 1I). Furthermore, CBCT examination revealed an arrested resorptive process and normal PDL (Figure 1J and 1K); indicative of treatment success.
