In this clinical case report, Dr. Zak James demonstrates the use of the EdgeOnyx file system to treat a mandibular third molar with an uncommon anatomical variation known as radix paramolaris. The case highlights the challenges of locating and negotiating an additional canal in a posterior tooth with limited access and visibility.
Dr. James illustrates how the EdgeOnyx system’s heat-treated, pre-bendable files facilitated conservative canal negotiation, particularly with the X-Find 09/.09 and X-Follow 15/.04 files. The case demonstrates how the system can help clinicians navigate complex anatomy, preserve existing restorations, and achieve predictable endodontic outcomes.
