A WaterLase laser system equipped with patented Radial Firing Tips can remove the infection-harboring instrument smear layer remaining after rotary or hand instrumentation of the root canal. This smear layer not only contains infected tissue, but can seal infection within dentinal tubules.

Scanning Electron Microscopy (SEM) shows treatment with WaterLase and Radial Firing Tips leaves canal walls free of smear layer and opens dental tubules, allowing YSGG laser energy to penetrate and destroy bacteria.
The literature shows that open dentinal tubules result in superior disinfection, minimally invasive access, greater efficacy, and more promising long-term results for the treated canal.
Why do treatments fail even when all canals are located and cleaning and enlargement is successful? Research shows that most root canal treatment failures are caused by persistent or secondary intraradicular infections, with E. faecalis, the most prevalent species. WaterLase treatment may reduce the incidence of retreatment.
As is widely known, most root canal treatments fail due to residual E. faecalis in the canal. WaterLase systems equipped with patented Radial Firing Tips dramatically reduce the existence of E. faecalis in the pulp chamber and root canal space.

The RFT root canal therapy kit for WaterLase systems is indicated for cleaning and disinfection of the root canal after endodontic instrumentation.
RFT root canal therapy system includes one 200 micron and one 300 micron radial firing tip.
The system achieves a significant reduction in bacterial counts in only three minutes compared to 20-30 minutes of conventional treatment.²
"I believe that the use of lasers in root canal therapy, specifically the Waterlase product, has the potential to revolutionize and totally change our specialty."

"First, these bacteria [E. faecalis] are known to be highly resistant to other disinfection currently used in root canal therapy. Second, the research demonstrates that the disinfection capability of the laser is effective at a distance into the dentin surrounding the canal, overcoming some accessibility problems for conventional treatment methods. Third, a high level of disinfection can be achieved in minutes, saving both the patient and dentist considerable time during endodontic treatment."
