Introduction: With the current scientific evidence there is no defined protocol for the treatment of peri-implant diseases, such as mucositis and peri-implantitis, but nevertheless there is a list of recommendations to obtain the best result. The objective of this study is to see if the use of laser is beneficial when used as an adjunctive therapy to surgical or non-surgical treatments and to understand if it may one day become a gold standard treatment for peri-implant diseases such as mucositis and peri-implantitis. Materials and methods: An electronic search was performed in MEDLINE (NCBI pubmed and PMC), Scopus and Elsevier databases. The key words used in the searches were as follows: ("periimplantitis" OR "peri-implantitis" OR "mucositis") AND ("low-level laser therapy (LLLT)" OR "photobiomodulation therapy") AND ("clinical" OR "in vivo" OR human) or ("CO2" OR "DIODE" OR "ER: YAG" OR "ND:YAG" OR ER,CR:YSGG") AND (Peri-implantitis OR mucositis). Results: A total of 2958 studies were analyzed after searching with keyword combination. A total of 951 duplicates were removed. After a first reading of the title and abstract 1923 publications were removed. In a second reading the full text of 84 articles was analyzed by 2 independent researchers (JM and GF), at this point 77 articles were excluded from the review, only 7 were chosen to be part of the review this selection was determined based on the exclusion and inclusion criteria. Conclusion: Based on the limited evidence currently available, we cannot establish any conclusion per se due to the existing heterogeneity and the small number of included trials which was a problem within the scope of this review. Laser treatment has been shown to have benefits, but it remains a major question whether there is potential for its use in the treatment of peri-implant diseases.
