This clinical video showcases the shaping of a narrow and curved root canal system using the HARMONY file sequence by Fanta Dental. The procedure highlights the use of Harmony 17/.04, 22/.04, and 30/.04 files, emphasizing their flexibility and cutting efficiency.

The AF-L wire technology and variable cross-section design of these files facilitate safe and effective navigation through challenging canal anatomies, minimizing the risk of ledging or instrument separation.
