Comparison of apical debris extrusion using clockwise and counter‐clockwise single‐file reciprocation of rotary and reciprocating systems

The aim was to evaluate apical debris extrusion produced by a single‐file system used in counter‐clockwise reciprocation and compare it to rotary single‐file systems used in clockwise rotation and clockwise reciprocation. A total of 100 first mandibular molars were divided into five groups (n = 20):...

Description
Summary:The aim was to evaluate apical debris extrusion produced by a single‐file system used in counter‐clockwise reciprocation and compare it to rotary single‐file systems used in clockwise rotation and clockwise reciprocation. A total of 100 first mandibular molars were divided into five groups (n = 20): (i) WaveOne Gold Glider and Primary instrument in counter‐clockwise reciprocation; (ii) One G and One Curve file in clockwise rotation; (iii) One G and One Curve file in clockwise reciprocation; (iv) TruNatomy Glider and Prime instrument in clockwise rotation; and (v) TruNatomy Glider and Prime instrument in clockwise reciprocation. Apical debris extruded was measured after glide path preparation and canal preparation. WaveOne Gold displayed significantly higher amounts of apical debris extrusion in all the groups (P
