Fig. 3From: Comparison of canal transportation and centering ability of manual K-files and reciprocating files in glide path preparation: a micro-computed tomography study of constricted canalsMean canal centering ratio values and statistical analysis in two experimental groups (n = 15). A result of 1 indicates perfect centering ability. Group 1: Glide path was established by using #10-#15 stainless steel K-files manually; Group 2: #10–#15 Mechanical Glide Path super-files were used with OGP motion (OGP 90°, 300 rpm)Back to article page
