2. MPro 3 Files System
• 3 files System.
• convex triangular cross-section design.
• High cutting efficiency.
• Very high flexibility files (thermal treated surface).
• High surface resistance (reduce liability to fracture).
• Reduce debris that stick between flutes.
• Easy to handle and safe.
• Non-cutting tip design reduce risk of apical transportation.
• Lower cost compared to other systems.

3. MPro 18-file
• Used for preparation of coronal third of the canal.
• 21mm length.
• Tip diameter 0.18 mm with tapering 0.04.
• Used with torque 3Ncm and with speed 450-500 Rpm.
• If used to prepare all canal then it will be fracture in the 1st encountred
curve.

4. • Used for preparation of of apical third till apical constriction.
• 25mm length.
• Tip diameter 0.20 mm with tapering 0.04.
• Used with torque 1.5-2.5Ncm and with speed 450-500 Rpm.
• Clean the canal of the remaining pulp or other debris and make
primary shaping.
• If we have a narrow canals or severly curved canals
we could finish cleaning and shaping till 20-file.
MPro 20-file

5. MPro 25-file
• Used for preparation and shaping all canal till
apical constriction.
• 25mm length.
• Tip diameter 0.25 mm with tapering 0.06.
• Used with torque 1.5-2.5 Ncm and with speed 450-500 Rpm.
• Clean the canal of the remaining debris and give
the final shaping.
• Preferred in normal and wide canals like single canal teeth, palatal and distal
canals in upper and lower molars.

6. Canal preparation technique
• Working length determination by ss k-file 10 or 15 with X-ray and apex locator.
• Straight line access should be achieved by suitable size gates glidden, then
irrigation with NaOCl 2.5%
• MPro 18 file with EDTA is used for preparation of coronal third,then irrigation with
saline then thorough irrigation with NaOCl.
• Now, 20 file is used for canal preparation from apical third, then irrigation with
NaOCl.
• 25 file finally is used for complete canal shaping, then thorough irrigation with
NaOCl.

7. Canal obturation
• Drying the canal by paper point according to master file taper and diameter.
• After achieving a full dry canal, fit cone of gutta percha is placed in the
prepared canal and an x-ray shot is taken.
• If the master cone is suitable to working length with tug back, we fix it in the
canal with sealer , and put accessory cones if there’s a lateral space.
• Remove the excess by gutta cutter or heated plugger.
• Finally, we take a post operative x-ray to insure that every thing is ok.
