Antibacterial effect of Er:YAG laser in the treatment of peri-implantitis and their effect on implant surfaces: a literature review

The aim The present study aims to conduct a descriptive analysis by reviewing in vivo and in vitro studies concerned with the antibacterial effect of Er:YAG laser (2940 nm) and their effects on implant surfaces at different parameters for peri-implantitis treatment. Materials and methods The PubMed and Google Scholar had been used to search for articles focused on the antibacterial effect of Er:YAG laser (2940 nm) in the treatment of peri-implantitis and their effects on implant surfaces. This literature search was limited to 10 years (January 2007–March 2017). Results The safe settings of Er:YAG laser (2940 nm) which may be used as an antibacterial effect without surface alteration or increase of temperature in the treatment of peri-implantitis are 100 mJ/pulse, 1 W, 10 Hz, and 12.74 J/cm 2 for 60 s. Conclusion A consideration should be taken when Er:YAG laser 2940 nm wavelength is used to avoid a negative thermal and characteristic effect on the implant surfaces, where the favorable settings which can be used in the treatment of peri-implantitis are 100 mJ/pulse, 1 W, 10 Hz, and 12.74 J/cm 2 for 60 s.
