Endodontic Management of Curved Canals with ProTaper Next: A Case Series

The curved and dilacerated roots in the posterior teeth often present the major challenge to the clinicians during the endodontic treatments. The efficient biomechanical preparation is also affected by improper instrumentation in the curved or the 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 ProTaper Universal rotary instruments has made a significant impact in the biomechanical preparation of root canals systems. However, the fracture rate of these files and inconvenience to treat the posterior teeth in reduced mouth opening conditions limits their successful usage in endodontic treatments. The ProTaper Next rotary instruments have noted advantages such as increased flexibility, higher strength, and wear resistance over the conventional rotary endodontic systems. The current case series discusses the endodontic treatment of three severely curved root canal systems successfully treated with ProTaper Next rotary endodontic system.
