Managing narrow and calcified canals is one of the biggest challenges in endodontics, requiring precision, flexibility, and the right tools.
The Harmony system from Fanta provides hybridization not only within a sequence but also in a single file, Thanks to the variable cross section within a file offering a cost-effective solution without compromising functionality.
This ensures efficient and safe canal shaping, even in difficult cases.
Paired with the iRoot Pro endomotor, which offers multiple functionalities at an economic price, this combination enhances control and precision. Harmony’s flexibility and controlled cutting improve navigation in tight spaces, while iRoot Pro’s adaptive settings optimize performance. Together, they simplify the management of complex anatomy.

Preoperative radiograph
Tooth no. 47 was diagnosed as Necrotic tooth with choronic periodical access.
From Preoperative radiograph it was evident presence of narrowness in the coronal portion of medial canals that require special attention and care,

Conclusions
Harmony and iRoot Pro offer a smart, efficient approach to managing narrow and calcified canals.
With hybridization in a single file and an adaptable endomotor, they simplify treatment while preserving dentin.
