Abstract：AIM:To evaluate the clinical outcome of reciprocal instrument clamping K file in the negotiation of calcified root canals. METHODS:167 calcified root canals of 112 teeth from 96 patients with pulpitis or apical periodontitis were negotiated with reciprocal instrument clamping K file and the outcome were evaluated. RESULTS:131(78. 44%) calci-fied root canals were successfully negotiated. Correlation was found between the success rate and tooth location, the success rate of the anterior teeth group was higher than that of the molar group (P<0. 05);the success rate of the canals with calci-fication of coronal to the bend position was significantly higher than that of apical to the bend position(P<0. 05). CON-CLUSION:The reciprocal instrument clamping K file is safe and effective in the treatment of calcified root canal, but it has certain limitation in negotiating the calcification of the root canals at apical to the bend position.
