This is the first in the line of sure to be many more studies done with PIPS. I have been using it for a few month and we have gotten really good results! The patients like it and we have very little post -op discomfort. NOTE: Final Fill photos of PIPS cases found at the end of the blog “New service to our patients: Laser Root Canals!”.

Title: “Effectiveness of the Erbium:YAG laser and new design radial and stripped tips in removing the smear layer after root canal instrumentation”.
Order of Authors: Enrico DiVito, DDS;Ove A. Peters, DMD MS PhD;Giovanni Olivi, M.D.,D.D.S.
Abstract: The aim of this study was to analyze, in vitro, the debriding ability of an Erbium:YAG (Er) laser system (2,940 nm) equipped with a newly designed radial and stripped tip of 400 micron diameter, using scanning electron microscopy (SEM) analysis. Eighty single-rooted extracted human teeth were endodontically prepared with rotary instrumentation and standardized chemical irrigation, using 5.25% sodium hypochlorite (NaOCl). At the end of mechanical instrumentation, four different final protocols were used: (G1) two minutes saline water irrigation as control group; the other groups (G2, G3, G4) were irradiated with an Er laser at 25mJ, 15Hz, 50?s pulse duration with laser spray off, using the tip in the coronal opening of the wet root canal. Different solutions and irradiation times were used: (G2) 20 sec. Er:YAG laser irradiation in sterile distilled water, wet canal; (G3) 20 sec. Er:YAG laser irradiation in 17% EDTA, wet canal; (G4) 40 sec. Er:YAG laser irradiation in 17% EDTA, wet canal. Scanning electron microscopy (SEM) analysis evaluated the debridement and smear layer removal at the apical third. The study showed that standardized instrumentation, followed by a final Er:YAG laser irradiation in EDTA wet canals, resulted in more cleaning of root canal walls and a higher quantity of open tubules in comparison with the traditional irrigation method.
