A new possibility to improve the results of the laser therapy is the control of the laser radiation by a feedback system that selectively detects subgingival calculus. This study compared the effects of fluorescence\u2010controlled Er:YAG radiation after SRP with SRP alone on the treatment of chronic periodontitis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design\/Materials and Methods<\/jats:title><jats:p>Thirty patients with chronic periodontitis were randomly distributed into two groups of 15 patients to receive: SRP or SRP followed by fluorescence controlled Er:YAG laser (SRP+ERL). Clinical parameters including probing pocket depth (PPD), bleeding on probing (BOP), and plaque index (PI) were recorded and samples of gingival crevicular fluid (GCF) and subgingival plaque were taken at baseline, 4 and 8 weeks postoperatively. The laser therapy was performed 1 day after the SRP procedure. The GCF samples were analyzed for interleukin\u20101beta (IL\u20101\u03b2), tumor necrosis factor alpha (TNF\u2010\u03b1) and total antioxidative status (TAS). Subgingival plaque was examined by culture for 10 bacteria.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>During the observation periods (4 and 8 weeks postoperatively), no statistically significant differences were detected for clinical, microbiological variables and TAS of GCF between SRP and SRP+ERL groups. However, the amount of IL\u20101\u03b2 and TNF\u2010\u03b1 in GCF was increased after SRP procedure in contrast to a slight decrease of their levels after SRP+ERL treatment, where in addition the process of recolonization seems to be more delayed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>SRP+ERL allowed a decrease of the levels of proinflammatory cytokines and prevented a fast process of recolonization.
