Assessment of shaping ability of stainless steel files in curved canals / 实用口腔医学杂志

ABSTRACT

Objective:To evaluate shaping ability of stainless steel fi les. Methohs A computer assistant measure system for the simula tion of root canal was set up and used for quantitative analysis of root shape o f eight simulated root canals during stainless steel files shaping process. Results:Although the stainless steel files were precurved, they stra ightened the simulated canals obviously. The cutting of the stainless steel file s on curved root canals was unbalanced. Conclusion:More flexible files and improvement of technique are essential for curved canals shaping.
