IL‐1β, TNF‐α, total antioxidative status and microbiological findings in chronic periodontitis treated with fluorescence‐controlled Er:YAG laser radiation

Abstract

SRP+ERL allowed a decrease of the levels of proinflammatory cytokines and prevented a fast process of recolonization.

Effect of Photodynamic Therapy, Diode Laser, and Deep Scaling on Cytokine and Acute‐Phase Protein Levels in Gingival Crevicular Fluid of Residual Periodontal Pockets

“…Only two studies have reported differences in the expression of certain GCF components: Liu et al 39 reported that the Nd:YAG laser combined with SRP showed a higher reduction of GCF IL‐1β at 6 and 12 weeks after treatment than either laser alone or SRP alone. Dominguez et al 40 monitored the levels of GCF IL‐1β and TNF‐α during a period of 8 weeks after SRP alone or SRP plus Er:YAG laser radiation. GCF levels of IL‐1β and TNF‐α were higher after SRP alone and slightly lower after the combined procedure.…”

Antibacterial effect of using the Er:YAG laser or Er,Cr:YSGG laser compared to conventional instrumentation method—a literature review

“…Lopes et al (2010) determined that in non-surgical periodontal treatment, Er:YAG laser may be an alternative treatment for reduction and control of the proliferation of microorganisms in persistent periodontitis [7]. Domínguez et al (2010) have also demonstrated that the use of the Er:YAG laser radiation as a coadjutant of scaling and root planing (SRP + ERL) allowed a decrease in the levels of pro-inflammatory cytokines and prevented a fast process of recolonization. This study also remarks that the adjunctive application of fluorescencecontrolled Er:YAG laser radiation prevents a fast process of recolonization [8].…”

“…This thin, initial biofilm has been almost always present on the tooth surface as it forms immediately after cleaning [2]. An initial few layers (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) of the biofilm consist mostly gram-positive cocci bacteria, followed by some gram-positive rods and filaments, and a very small amount of gram-negative cocci. The gram-positive cocci species involved in this conditioning layer include, but are not limited to, S t re p t o c o c c u s m u t a n s , S t r e p t o c o c c u s m i t i s , Streptococcus sanguis, Streptococcus oralis, Rothia dentocariosa, and Staphylococcus epidermidis.…”

Laser Radiation as an Adjunct to Nonsurgical Treatment of Periodontal Disease

“…Finally, more encouraging were the results obtained by Domínguez, when Er:YAG laser was employed as an adjuvant to SRP. Though no statistically significant differences were observed between both groups in any of the investigated clinical parameters (Domínguez et al, 2010) (Fig. 6), the cytokine levels in the GCF were reduced with the feedback-controlled Er:YAG laser radiation (Fig.…”
