In this study, the authors from Peoples Friendship University of Russia (RUDN university) present the results on the effectiveness of the root canal disinfection using an erbium laser in combination with a 17% solution of ethylene diaminetetraacetic acid (EDTA) in vitro and in clinical studies.

An experimental group of teeth was treated medically according to a standard protocol using 3% solution of sodium hypochlorite and 17% solution of EDTA followed by irradiation with erbium laser. The control group was treated similarly but without laser irradiation.

The obtained results prove that the modification of the root canal treatment by the inclusion of erbium laser irradiation is a promising direction in endodontics.
