1The protocol

Four steps, familiar workflow.

SWEEPS slots into how you already do endo.

Prep

Access and shape

Open and shape the canals the way you normally do.

Fill

Flood the chamber

Fill the pulp chamber with irrigant and place the SWEEPS tip in the chamber, not down the canal.

Activate

Stream the irrigant

Paired ultra-short pulses create shock waves that drive irrigant through the whole canal system.

Finish

Obturate

Rinse, dry and obturate. The cleaner canal walls take filling material well.

R-SWEEPS is LightWalker's newest endo mode. It raises pressure along the canal for even stronger flushing, without raising the risk of pushing irrigant past the apex.

2For your patients

Why patients say yes.

Cleaner, more thorough endo

Irrigant reaches anatomy that instruments miss, which is where bacteria hide.

Help with difficult anatomy

Curved and lateral canals get cleaned without forcing a needle to length.

Tooth structure preserved

Irrigation does the cleaning, so you don't need to enlarge the canal just to get fluid to the apex.

3For your practice

Why it pays.

Keep more endo in-house

Confidence to take on cases you might have referred to an endodontist.

Adds to cases you already do

No new appointment type. It upgrades every root canal you treat.

Runs on every LightWalker

SWEEPS is standard across the AT S and ST-E lineup.

4The evidence

What the research shows.

studies in a 2025 systematic review of laser-activated irrigation.

Best

reduction near the apex came from SWEEPS in that review.

extra canal enlargement needed to reach the apical third.

Lateral canal filled after SWEEPS-assisted irrigation and obturation.

Systematic reviewSWEEPS and PIPS for canal disinfection

Fifteen studies. Laser-activated irrigation outperformed conventional irrigation for smear layer removal and biofilm disruption, with SWEEPS strongest near the apex.
