Description
Maria Fernanda Silva Andrade-Bortoletto and six colleagues present a 2026 laboratory study comparing two imaging routes for finding a hidden second root canal in lower front teeth. Missing such a canal is a known cause of root canal treatment failure, and a nearby zirconia implant might distort the images.
Twenty extracted incisors, some with one canal and some with two, were set in a human jaw beside an implant. Five evaluators read angled X-ray pairs and two cone-beam scan protocols. All routes performed comparably, and the implant did not reduce accuracy. The authors say the simpler X-ray technique remains a valid choice here.
