The principal characteristics of K‐type files are described and the succession of operations as prescribed by the ‘balanced force’ method of preparation of root canals, particularly curved root canals, examined. On the basis of a simple mathematical model, the motions of a file in a straight canal and in a curved canal are successively considered, and the merits of the recommended method highlighted and confirmed.
