Intro to Endodontics

Apical preparation is done first with MAF, then stepwise reduction of the WL for larger files, in 0.5-1 mm steps = ↑ Flared shapes

Remove debris created during shaping, dissolve organic and inorganic tissues, remove and prevent smear layer, lubricate RC, and serve as an antimicrobial agent.
