Fig. 1From: Comparison of glide paths created with K-files, PathFiles, and the ProGlider file, and their effects on subsequent WaveOne preparation in curved canalsImage matching of pre-glide path preparation, post-glide path preparation and post-root canal preparation. Note the difference between pre-glide path (dark grey), post-glide path (neutral grey) and post-root canal preparation (light gray) at the 1, 3, and 5 mm levels from the apical foramen.
