Protaper endodontic system

2. Tapering
•The progressively tapered design
improves flexibility,
Cutting efficiency and
the safety of these files .
•Change percentage of taper over the
length of cutting blades (unique feature ).

3. Cross-Section
• Convex triangular.
•Decreases friction between blades of file
and canal wall.
• Increasing its cutting efficiency.

4. Tip
•modified guiding tip.
•rounded, non-cutting
▪Better follow the canal.
▪loose debris into
the intrablade flutes.

5. •Variable tip diameters of ProTaper file
allows it to have specific cutting action in
defines area of canal without stressing
instrument in other sections.

6. Benefits of design:
• Increased flexibility
•Each instrument produces as
larger tapers make way for
smaller tapers.
•Protaper files engage a smaller
area of dentine reducing torsional
loads and file fatigue

7. Protaper Files
The ProTaper system
consists of just three
shaping and five finishing
files

9. ProTaperfor Hand Use
Clinical Procedures
• Explore Canal w/ #10 hand
file
•Negotiate to #15 w/
hand file

10. ProTaperfor Hand Use
Clinical Procedures
• Explore Canal w/ #10 hand file
• Negotiate to #15 w/ hand file
•Coronal Flaring w/S1
Insert file with slight apical
Pressuer until resistance
½ turn clockwise
½ turn anticlockwise
Withdraw
Clean

16. • Explore Canal w/ #10 hand file
• Negotiate to #15 w/ hand file
• Coronal Flaring w/S1
• Coronal Flaring w/ SX
(optional) using same motion
May replace w/ GG Drill

20. • Explore Canal w/ #10 hand file
• Negotiate to #15 w/ hand file
• Coronal Flaring w/S1
• Coronal Flaring w/ SX
• Working Length Determination

21. • Explore Canal w/ #10 hand file
• Negotiate to #15 w/ hand file
• Coronal Flaring w/S1
• Coronal Flaring w/ SX
• Working LengthDetermination
•Coronal 1/3 Preparation w/ S1
again(up to full working length)
using same motion

22. Middle 1/3 Preparation w/
S2 (up to full working
length) using same motion
• Explore Canal w/ #10 hand file
• Negotiate to #15 w/ hand file
• Coronal Flaring w/S1
• Coronal Flaring w/ SX
• Working LengthDetermination
• Coronal 1/3 Preparation w/ S1

24. • Explore Canal w/ #10 hand file
• Negotiate to #15 w/ hand file
• Coronal Flaring w/S1
• Coronal Flaring w/ SX
• Working LengthDetermination
• Coronal 1/3 Preparation w/ S1
• Middle 1/3 Preparation w/ S2
Apical 1/3 Preparation
w/ F1 & F2, using the
same motion

26. For larger canals, continue
apical prep w/ F3, using also the
same motion

27. Rotary system
• Protaper nickle-titaninm rotary files
substantially simplify root canal
preparation,particularly in curved and
restricted canals

28. Guidelines
• Frequently clean & inspect files
• Use only in well irrigated canals
• Never force instruments
•Recommended speed is
150 to 350 rpm

30. Retretment
