Lares Research has introduced photon-induced photoacoustic streaming (PIPS), a new method for chemically cleaning and debriding the root canal system using erbium-doped yttrium aluminum garnet (Er:YAG) laser energy at subablative power levels. The patent-pending procedure is being called the first real breakthrough in endodontics in 50 years, according to the company.
The PIPS procedure uses the power of an Er:YAG laser to create photoacoustic shock waves within a 15% EDTA (ethylenediaminetetraacetic acid) solution introduced in the canal. The containment of the shock waves within the canal system thoroughly streams the EDTA solution through the entire canal, selectively removing debris, according to Lares. The subcanals are left clean, and the dentinal tubules are free of smear layer. The procedure is equally effective for final water rinsing prior to obturation.
The PIPS procedure was developed by Enrico DiVito, D.D.S., founder of the Arizona Center for Laser Dentistry, along with his research team at Medical Dental Advanced Technologies Group, with assistance from Mark Colonna, D.D.S. The procedure has been optimized for use with the Lares Fotona PowerLase AT and is available only to past and future purchasers of the PowerLase AT, according to the company.
