LightSpeed 2.0 (LS2)LightSpeed 2.0 (LS2) Reflects 12 years of experience with LS1.
Reduces chance of leaving a separated instrument in the canal. Features a “safe failure mode”.
No grinding necessary when making instrument thus no surface defects and no cause for premature failure.
Easier instrument identification.
Length markings more visible and match those of our K-files.
“Spade blade” provides more space for debris. No flutes to clog. Its cutting efficiency remains the same.
LightSpeed 2.0 (LS2)LightSpeed 2.0 (LS2)
No significant changes compared to LS1; technique and equipment pretty much the same.
Symmetrical blade eliminates rotation procedural error; use clockwise OR counterclockwise rotation.
Better tactile feedback.
More flexible shaft and shorter cutting blade negotiates the more difficult curves better.
Flat blade design provides ample space for bypassing - if necessary.
Examples of “Fail Safe” SeparationExamples of “Fail Safe” Separation
Excessive torsional force causes instrument to twist and possibly separate. This makes retrieval from canal easy.

Determining First LS to Bind (FLSB) Changes to Gauging Technique (By Hand)
To Gauge: turn
instrument 360 degrees
LS2 goes to WL in this orientation
But binds when rotated
Solution: Try next smaller size instrument

Technique ChangesTechnique ChangesRecommended by EvaluatorsRecommended by Evaluators
From “very light touch” to “light push”
Be aware of canal anomalies that could “catch”
and twist-up instrument
LS2 instruments perform better at higher speed
and with higher torque handpiece. Use speed
range no lower than 2000 rpm, 2500 rpm is
preferred.
