Treatment of severely curved root canals with the single file rotary NiTi F6 SkyTaper system: A case report

Curved root canals are within the complex anatomic range of the root canal system and a possible reason for failure in the preparation of the root canals during root canal treatment. The introduction of NiTi files was a milestone for accessing difficult root canal anatomy. Lately, manufacturers have focused on the development of single file NiTi systems. The comparison of these rotary single file systems to the established full sequence NiTi systems, particularly with regard to their performance in curved canals, is being researched thoroughly. The main objective of this case report is to show the clinical performance of the rotary NiTi single file system F6 SkyTaper (Komet, Lemgo, Germany) in severely curved root canals.
