Lightspeed and quantec files

LIGHTSPEED FILE

Ø  Resembles a Gates-Glidden drill  

Ø  Used in apical curvatures where rotary instruments may be in jeopardy.

Ø  Speed: 1,300 to 2,000 rpm 

Ø  The instruments come in ISO sizes beginning with No. 20  to 140.

Ø  Advantages: the ability to finish the apical-third preparation 

QUANTEC FILES

•          Although called a “file,” is more like a reamer—a drill.

•          Produced in three different tapers—0.02, 0.04, and 0.06.

•          Quantec flare series — 0.08, 0.10,& 0.12 taper for coronal 1/3^rd.

•          The radial lands of the Quantec are slightly relieved to reduce frictional contact with the canal wall, and the helix angle is configured to efficiently remove debris.
