Abstract:
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.
