Abstract / Excerpt:
The goal of endodontic treatment is to obtain effective cleaning and removal of the smear layer, bacteria and their by products within the root canal system. Endodontic techniques use mechanical instruments as well as ultrasonic and chemical irrigation in an attempt to shape, clean and completely decontaminate the endodontic system, but still fall short of elimination of the same. A recent advancement in the delivery of laser energy into the root canal system has been investigated, specifically the creation of a system of laser-activated irrigation (LAI) .In this work, a novel tapered and stripped tip of a laser-activated irrigation technique called photon induced Photo-acoustic streaming (PIPS) was used. PIPS is a unique laser application utilizing the Er 2,940 nm wavelength. The Er:YAG is used because of its high affinity, chromophore, for water, and its hydroxyl group with low energy levels of 20 mJ creates a significant and profound photo acoustic shock wave that allows for 3-dimensional (3-D) movement of the irrigants without the need to place the tip close to the apical terminus. PIPS has significantly demonstrated the ability to remove smear layer, debride canals, lateral tubules, delicate apical morphology, and eliminating bacteria.Unlike other laser systems, this application with these specific settings and the unique PIPS tip design yields a nonthermal subablative effect. The purpose of this article is to introduce the experimental background of this laser technique in removing bacterial load in areas where traditional methods may fail to succeed and to introduce the clinical protocol.
