The Effect of Using Reciprocal Files Alone and with Different Files on Postoperative Pain

In this clinical study, the teeth will first undergo coronal shaping with the One Flare file. Then, the glide path and final shaping will be performed in reciprocal mode with reciprocal files.

In this group, only the glide path and final shaping will be performed using reciprocal files, without coronal shaping.

In this group, shaping will be performed using only a reciprocating file, without coronal shaping and glide path preparation.

The operator prepared the glide path using a #15K-type stainless-steel hand file with push-pull motion. On sensing resistance, the file was withdrawn, recapitulation was performed with a #10K-type stainless-steel file, and debris was removed by irrigating the canals with 5% NaOCl. The operator repeated this procedure until the #15K-file reached the complete working length
