“…Based on many studies, Er:YAG laser used for scaling can effectively remove subgingival calculus without leading to any thermal alterations, such as carbonization, melting, or cracking, which are usually observed following carbon dioxide (CO2) and neodymium-doped yttrium aluminium garnet (Nd:YAG) laser irradiation. [11][12][13][14] In the present study, the effects of Er:YAG Laser and hand instrumentation methods on human gingival fibroblast (HGF) cells attachment to treated root surfaces and subsequently on morphology, viability and proliferation of attached cells were compared.…”

Introduction: The present study compared the effects of erbium-doped yttrium aluminium garnet (Er:YAG) laser and hand instrumentation on the attachment of human gingival fibroblast (HGF) cells to periodontally involved root surfaces. Methods: A total of 40 tooth specimens were collected and treated in four distinct groups: scaled and root planed with hand instruments, scaled with Er:YAG laser, treated with a combination of hand instruments and Er:YAG laser and non-treated control group. The attachment and proliferation rate of HGF were assessed using MTT assay and scanning electron microscope (SEM) examination was used for cell morphological evaluation. Results: The MTT (3-[4, 5-dimethylthiazol-2-yl]-2, 5 diphenyl tetrazolium bromide) assay showed significant decrease in HGF cell viability in both hand instruments only and combination treated teeth specimens compared to control specimens (P < 0.05), 24 hours after cell seeding. However, at time 48, the cell viability of attached cells in these 2 treated groups was almost similar to control. In contrast, at 24 and 48 hours after cell seeding, viability of attached cells was higher than control in Er:YAG laser treated only specimens (P < 0.05). According to SEM study, the laser treated specimens showed more surface roughness. Conclusion: Er:YAG laser increased attachment and proliferation of HGF cells in comparison to the hand instruments method.

“…31 In addition to chemical conditioning, the applicability of different laser systems such as CO 2 , Nd:YAG, diode and Er:YAG laser in the removal of the smear layer have been demonstrated. [32][33][34][35][36][37][38][39][40][41][42][43] However, until now, no published data have been available concerning the clinical outcomes following root surface biomodification with Nd:YAG laser for the treatment of gingival recession. Therefore, the aim of the present study was to evaluate and compare the outcome of gingival recession therapy using the SCTG with or without Nd:YAG laser application for root surface biomodification.…”

Background=Aim: Root surface biomodification has been used to treat gingival recession and periodontitis. The principle for this procedure is that removing the smear layer from the root surfaces exposes collagen fibers, which leads to improved healing. Clinical studies generally have failed to find any improvement in clinical parameters when using such procedures, however. The aim of this study was to evaluate and compare the outcome of gingival recession therapy using the subepithelial connective tissue graft (SCTG) with or without Nd:YAG laser application for root surface biomodification. Materials and Methods: Thirty-four teeth in 17 patients with Miller Class 1 and 2 recession were treated with SCTG with (test group) or without (control group) the application of Nd:YAG laser (1 W, 10 Hz, 100 mj, 60 s, 1064 nm). Clinical attachment level (CAL), recession depth (RD), recession width (RW), and probing depth (PD) were measured at baseline and six months postsurgery. Results: Both treatments yielded significant improvements in terms of RD and RW decrease and CAL gain compared to baseline values. For test and control groups, the average root coverage was 33% and 77%, respectively (p < 0.05), and the complete root coverage was 18% and 65%, respectively (p < 0.05). The control group showed a greater reduction in RD and RW compared with the test group (p < 0.05). Conclusions: The use of Nd:YAG laser as a root surface biomodifier negatively affected the outcome of root coverage with the SCTG.

“…Therefore, it involves less thermal risk for mineralized surfaces [20,21]. 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].…”

“…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.…”

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

Background data Although many studies have evaluated the effectiveness of the Er:YAG laser or Er,Cr:YSGG laser as an adjunct to initial periodontal therapy, there was no literature review after 2007 on the antibacterial effect of erbium lasers and conventional periodontal instruments. Purpose The aim of this review was to evaluate the effectiveness of using Er:YAG laser or Er,Cr:YSGG laser on the reduction of bacteria causing the periodontal disease in comparison to that with the hand, sonic, or ultrasonic scaling devices. Material and methods This is a review based on the literature search in PubMed and Google Scholar. The search is limited to publications in the period between January 2007 and April 2017, in the English language. Results Fourteen publications were found to be appropriate to the inclusion criteria of this review and screened according to the research question: is there a difference in the effect on the bacteria causing the periodontal disease by using Er:YAG laser or Er,Cr:YSGG laser in comparison to that with the hand, sonic, and ultrasonic scaling devices? Conclusion The beneficial effects of the erbium lasers as an adjunct to SRP have been established. By using the erbium lasers as an adjunctive therapy to the SRP, the users can have better antibacterial effects than conventional methods.
