# EdgeOnyx: A Case Report For Mandibular Third Molar with Radix Paramolaris, by Dr. Zak James

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.
