The Posterior teeth often present with curved and dilacerated roots, a significant challenge for the clinicians during the endodontic treatments. The efficient biomechanical preparation is also affected by improper instrumentation in the curved or constricted canals. The use of conventional instruments and techniques in the dilacerated roots may develop ledges, fractured instruments, and canal blockages which further complicate the endodontic treatments. The introduction of Fanta AF-F One rotary file instruments has significantly impacted the biomechanical preparation of root canals systems. The Fanta AF-F One rotary file has noted advantages such as increased flexibility, higher strength, and wear resistance over the conventional rotary endodontic systems. The present case series discusses the endodontic treatment of two severely curved root canal systems successfully treated with Fanta AF-F One rotary file endodontic system.
