Abstract
Until nowadays the problem of finding the most effective method for root canals instrumentation and chemical irrigation is still open. Researchers are trying to find the easiest and simplest way to perform endodontic treatment and most importantly it should be effective in long term follow up.
There are different techniques to use lasers during endodontic treatment. One concept is to activate irrigation solution (Sodium hypochlorite or EDTA) – it is called laser-activated irrigation (LAI). Another technique is to use distillate water as an irrigation solution and 2 wavelengths: combination of Erbium and diode lasers. Erbium lasers are used for removing the smear layer to open dentin tubules and diode lasers in dry root canal for anti-microbiological effect.
Erbium lasers effectively remove the smear layer during working regarding caries and non-carious lesions treatment and before final obturation in endodontic treatment.
In our research from 2019 Er:YAG showed high anti-microbiological potential during endodontic treatment. Research showed effectiveness of Er:YAG lasers in removing smear layers during endodontic treatment. Due to laser selectivity and targeting only chromophores depending on the wavelengths of laser used we could speak about minimal invasive dentistry as a one page of modern biological dentistry.
