title: Initiation of polymerization with ultrasound in dental composite resin.
abstract: A single paste composite resin comprising methacrylate monomers, inorganic fillers, activators and an ultrasonic generator assembled by a piezoceramic transducer and a working tip was developed. The resin can polymerize and harden under irradiation with ultrasound having frequencies from 20 to 50 KHz and intensity from 12 to 40 W/cm2. The new technology is promising as a safe and effective method for restoration of tooth defects.
