The introduction of reciprocation and single file techniques have made root canal shaping procedure a clinically easier and more reliable procedure for all clinicians. After scouting the canal and the glide path management, shaping canals may often be achieved with only one file, in most of the cases in less than a minute. A revolutionary reciprocating system was introduced in 2011. This unique movement created a new concept of a ‘single file shaping technique’. Further research and development featuring an advanced heat-treated nickel-titanium alloy with a parallelogram cross-section resulted in greater flexibility and increased resistance to cyclic fatigue among other improvements which were introduced into clinical practice only recently. This presentation will review mechanical root canal preparation and shaping in a step-by-step approach leading to clinical excellence.
- Understand the differences between rotary and reciprocating motions
- Review the influence of the rotary and reciprocating motions on the different paramaters of root canal preparation (fracture, canal transportation, debris extrusion, dentinal cracks, cleaning)
- Learn a reliable clinical step-by-step for excellent root canal shaping
- Understand the limits and contra indication of mechanical root canal shaping
