Protocol
1
1. Canal Assessment
Evaluate canal anatomy with radiograph. Establish glide path with #10 K-file.
2
2. Glide Path
Recommended: Create glide path with #15 K-file.
3
3. Shaping - Narrow Canals
Use K0 -> K1 -> K2 sequence. 300-400 RPM, light apical pressure.
4
4. Shaping - Wide Canals
Use SP1 -> SP2 -> SP3 sequence. 250-350 RPM.
5
5. Irrigation
Irrigate with NaOCl after each file change. Final rinse with EDTA.
6
6. Obturation
Fill the canal with appropriate obturation material.
Clinical Tips
- •Use low speed (300-400 RPM)
- •Apply light apical pressure
- •Clean the file after every 3-4 pecks
- •Advance in short movements (2-3mm)
- •Do not force beyond the apex
Warnings
- ⚠Do not advance beyond the apex due to physiologic root resorption
- ⚠Do not apply excessive torque
- ⚠Dentin walls are thin - advance carefully
Clinical Notes

- →Developed by Dr. Ganesh Jeevanandan
- →High cyclic fatigue resistance due to CM-Wire
- →Variable taper design adapts to canal anatomy
- →Kedo-S Gold: Gold heat treatment (Af 45-55C, martensitic phase)
- →Kedo-S Plus: Dual metallurgy (Gold + Blue) combination
