Lateral root perforation unnoticed during post‐space preparation, and followed by post cementation, can subsequently be challenging to diagnose in the labio‐lingual plane due to the two‐dimensional nature of conventional radiography. This paper demonstrates the application of a recently developed three‐dimensional imaging system, cone beam computed tomography, in the diagnosis of iatrogenic root perforation. A clinical case is reported where labial post perforation in a maxillary central incisor occurring 15 years previously presented with a sinus tract and radiolucent lesion. Non‐surgical retreatment and perforation repair using mineral trioxide aggregate was performed with the aid of an operating microscope. The sinus tract resolved with radiographic evidence of healing at 1‐year recall.
