1) The document discusses root canal preparation and selection of nickel-titanium (NiTi) rotary files. It provides guidelines for proper root canal preparation including evaluating radiographs, understanding root canal anatomy, and establishing working length. 2) Key principles are outlined for selecting and using rotary files including assessing case difficulty, establishing a glide path with small manual files, using light touch at low rpm, and following a crown-down sequence. 3) Specific file systems are described including the Ramo RCS Silver Magic path files and Rainbow One single-file system for shaping canals. Guidelines are provided for proper use and specifications of these file systems.

2. • Each root canal has to be addressed individually.
• Root canal preparation should be planned thoroughly
before starting treatment.
• Careful evaluation of radiographs is mandatory.
Factors affecting planning and performing root canal preparation :
 Anatomy of the root canal
 Microbiology of the root canal
 Instruments available for preparation.

3. Selection of NiTi Rotary Files
Correct Choice for Rotary Files depend on,
 Understand the fundamentals of file design
 pre-clinical trial.
1. Assess the difficulties of the case

2. Prepare with hand files or path files up to size #20
prior to rotary use--- glide path

4.Use light touch and low rpm --don’t force the file
5. Proceed with crown-down sequence preparation
6. Replace rotary instruments frequent to avoid overuse
7. Avoid Cutting With the Entire Length of File—the more
file engaged in the root canal, the higher potential
for instrument fracture

6. 8. Don’t Start and Stop—sudden changes in the direction
of a rotary caused by the operator must be
avoided. A smooth gentle reaming motion is
most efficient; rotaries should be inserted
and withdrawn from a canal while rotating.
9. Length Control is Critical—working length should be
well established
10. Don’t rotate a file inside a dry canal
