Background and Aim: Effective decontamination of dental implant surfaces is the most difficult step of periimplantitis treatment. The use of some lasers can be helpful not in the bacterial killing but also in removal of foreign substances.
A new side firing tip (SFT) of Waterlase iPlus laser was developed specifically for the treatment of periimplantitis. The aim of the study was to found the optimal parameters for efficient preparation of contaminated implant surface and to compare effectiveness of SFT to radial firing tip (RFPT8).
