Step back is the method of producing an apical flare with hand instruments

Crown down is th accepted method of producing apical flare with rotary

instruments..

So what's the choice if asking which is th best method of canal preparation

without mention hand or rotary instruments?

Hi collegues, i took the ckl class... They mentioned in the class that best way is- step back at apical third and crown down at coronal 2/3rd. Then merge at the junction.... Sabreena. Sent from my iPhoneOn 8 Apr 2012, at 02:03, "khalid.sindi" <khalid.sindi@...> wrote:

Salam Hibah,

Best method is crown down, becuase it gives your instruments more space cornonally, which facilitates canal preparation with a straight-line access. Also, it is better because it cleans the coronal part first, which contains 2/3rds of the bacteria in the canal system. It also, allows for a better flushing action of the irrigation solution, preventing apical pressure and harm to the periapical tissues.

I think it is taught in 15 out of 17 dental schools in the UK, so I think you can be quite confident when you say crown down is the best.

Best wishes
