WUHAN, China - July 11, 2021 - PRLog -- Introduction- The main goal of endodontic treatment is the effective cleaning of the root-canal system and preventing the reinfection.

Rationale for the use of Laser - Irrigation is an essential part of root canal therapy because it allows for cleaning and bacterial reduction beyond what can be achieved by root canal instrumentation alone.

Prerequisite for use of LASER in Permanent Tooth -

Root Canal Preparation – The minimum canal preparation for a 200µm laser tip to reach upto the apical area corresponds to ISO file size 30.

Wet canals – Any chemical irrigants can be used like sodium hypochlorite, EDTA or both one after the other. Dry canals are a complete contraindication while using laser.

Working length - It is measured 1mm short of actual working length. E.g. If the working length of a canal is 19mm. So 19-1= 18 mm. This 18mm will be the length up to which the laser tip will go inside the canal.

Settings/parameters for laser root canal disinfection – The laser we have used is S1 Pioon Laser at 980nm wavelength (https://www.pioon.com/products_dental_lasers.html) and a 200µm non initiated tip is used at 2 Watt and Continuous Mode

Steps for Root Canal Disinfection - Under rubber dam isolation all the steps till chemomechanical preparation (CMP) remains the same as Laser disinfection is the final step before the obturation.

First - Irrigation- Wet the canals first with chemical reagent

Second – Use of Laser - Motion or Technique of Use of Laser is as under -

- Withdrawal of the tip from the canal is done at the rate of 2mm/second

-  Disinfection starts from apex to canal orifice

-  Move the tip in circumferential manner without touching the walls of canal

- Not more than 3 pass per canal should be done

- Total time not exceeding 30sec per canal

Third – Wait and Irrigate – Wait for 10 secs between each pass and follow it by replenishing the canal with fresh irrigant

Fourth – Repeat the process – A Maximum of 3 pass per canal can be done in a sitting.

Conclusion - Given the complex root canal anatomy and the limited ability of chemical irrigants to three-dimensionally clean and disinfect the entire endodontic space, the lasers has seen to adjunctively enhance the effectiveness of endodontic treatment, endodontic retreatment and prevent any further endodontic reinfection
