Introduction: Root canal treatment aim to eliminate the root microbial load and prevent its reinfection. RCP produces the Smear layer, a negative factor in correct action of the irrigation solutions and root canal obturation. NaOCl is excellent in root canal disinfection, but can’t completely remove the smear layer, even combined with EDTA. Traditionally performed with a syringe-needle combination, irrigation as limited effect on apical third and complex anatomy of the canal. Thus, sonic, ultrasonic and laser devices were developed to improve irrigant effect. LAI produce a photoacoustic shockwave which provide a better removal of smear layer, debris and bacteria from the root canal walls. Objective: This integrative systematic review evaluates if activating an irrigation solution with a laser is more effective than traditional irrigation methods in disinfecting the root canal system, removing debris and smear layer. Materials and methods: A Literature search was performed in the PubMed, and ScienceDirect databases, using the following keywords: laser, root, canal, irrigants. The search was carried out between April 2023 and February 2024. Results: 211 articles were identified and after a rigorous analysis with submission to the inclusion and exclusion criteria, 15 scientific articles published within 10 years were selected. Discussion: In the apical third, laser devices improved disinfection power and smear layer removal. It also allows a better penetration of irrigation solution and sealer materials in dentinal tubules. Conclusion: In this integrative systematic review it was verified that the laser was more effective than other activation techniques in disinfecting root canals.
