POMONA, Calif., October 15, 2026 /CourierPR/ -- Kerr Dental, a company with a 135-year legacy in the dental industry, has introduced a new product designed to support endodontists and general practitioners in their retreatment procedures. The company announced the launch of the ZenFlex™ RT Rotary Retreatment File System, a dedicated four-file rotary system aimed at providing greater control, efficiency, and confidence during complex retreatment cases.
The ZenFlex™ RT system is part of the trusted ZenFlex™ family and is designed to help clinicians maintain natural anatomy while navigating uncertain canal anatomy. The system features a non-cutting tip, flexibility, and a minimally invasive design, allowing for the removal of existing obturation material and canal reshaping. With a maximum flute diameter of 1.0 mm, the files are designed to help conserve dentin during retreatment procedures, ensuring that as much natural tooth structure as possible is preserved.
The ZenFlex™ RT system is designed to support a streamlined retreatment workflow. The dedicated four-file sequence helps clinicians efficiently remove existing material and reshape canals, reducing the need to switch between multiple rotary systems or assemble an individual retreatment protocol. Groove markings visually indicate the recommended sequence, while ISO-standard color coding enables quick file-size identification during procedures.
Dr. Philippe Sleiman, a paid consultant for Kerr, emphasized the importance of maintaining control and respecting the original anatomy during retreatment procedures.
