Basic introduction

• Protaper is a based on a unique concept and
  comprised of just 6 endodontic instruments, made
  up of NICKEL TITANIUM.
• It consists of 3-shaping files and 3-finishing
  files.
• It was designed by
• Dr Cliff Ruddle
• Dr John West
• Dr Pierre Machtou.

• The cross section of Protaper is a modified
  K-type of design with sharp cutting edge and no
  radial lands. This creates a stable core and
  sufficient flexibility for smaller files, though
  the cross section of finishing files is slightly
  relieved for increased stability.

4
Unique design factors are.

• Varying tapers along the long axis of the
  instrument.
• The three shaping files have tapers that
  increases coronally and reverse pattern is seen
  in finishing files.
• Color coding.
• Currently lengths available are 21 mm 25 mm.
• Available as hand as well as rotary endodontic
  files.

Shaping files.

• There are 3-shaping files , S1, S2 Sx.
• S1 is the shaping file-one, purple colour.
• S2 is the shaping file-two, white colour.
• Sx is the shaper x or auxillary shaper, golden
  colour.
• The taper of all the shaping files increases
  coronally.

7
Finishing Files.

• There are 3-finishing files, F1,F2 F3.
• F1 is the finishing file one, yellow coloured ,
  Do diameter is 0.20 mm.
• F2 is the finisher file two, red coloured , D0
  diameter is 0.25 mm
• F3 is the finisher three ,blue coloured ,D0
  diameter is 0.30 mm.
• The taper increases apically.
• .Newer addition is F4 ( 40 mm) ,F5( 50 mm) , F6
  ( 60 mm )..

S 1 ( Shaper one )

• Shaping File one.
• Purple coloured.
• D0 diameter is 0.17 mm D14 diameter is 1.20 mm
• Prepares coronal 1/3rd of the canal.
• Non cutting modified guided tip.
• There are 12 increasing tapers along the length
  of the blade.

S 2 ( Shaper two )

• Shaping file two.
• White coloured.
• D0 diameter is 0.20 mm D14 diameter is 1.20mm.
• Prepares middle 1/3rd of the canal.
• Non cutting modified guided tip.
• There are 9 increasing tapers.

Sx ( Shaper X / auxillary shaper)

• Shaper X / Auxillary shaper.
• Golden coloured handle.
• D0 diameter is 0.20 D14 diameter is 1.20mm.
• It is used to do coronal flaring in the same way
  as done with GG drills i.e. cutting in out
  strokes.
• There is an aggressive cutting tip.
• There is a much faster rate of taper from D0 to
  D9 as compared to S1 S2 , i.e. at D6,D7,D8,D9
  the CS diameter is 0.50,0.70,90,1.10
  respectively.

• Yellow in colour.
• Used for finishing of apical 1/3rd
• D0 diameter is 0.20 mm.
• Between D0-D3 F1 has a fixed taper of 7 percent.
