Abstract:Objective: This in vitro study was designed to compare the disinfection potential of an Er:YAG photon-initiated photoacousitc (PIPS) irrigation mechanism to standard needle irrigation (SNI) in eliminating biofilms from complex root canal systems.
Method and materials:Twenty-four extracted mandibular molar teeth exhibiting a Vertucci Type II canal system were selected and underwent canal instrumentation to create either a minimal (20/.04) or fully-flared (25/.06) preparation. Teeth were inoculated with bacteria… Show more
