“…These characteristics were also demonstrated in other studies. 4,7 The surfaces irradiated with Er:YAG and Er,Cr:YSGG lasers showed similar morphological characteristics, including root surface roughness, no smear layer, open dentinal tubules and lack of thermal damage. These characteristics are consistent with those observed in other in vitro studies that evaluated the morphology of dentin irradiated with Er:YAG 4,8,11 and Er,Cr:YSGG lasers.…”

“…Both the photomicrographs of the samples that received blood tissue and those that received no blood tissue application were examined three times by an operator (JECS) previously trained and calibrated with two other operators (Kendall test, p < 0.05), using a single-blind method.

“…Some studies have shown that irradiation of root surfaces using Er:YAG lasers does not promote the formation of a smear layer. 4,7 Additionally, the Er:YAG and ErCr: YSGG lasers promote a selective removal of calculus with minimal damage to root surfaces, [8][9][10] and may be clinically effective for stabilizing the clinical parameters of periodontal disease. 2,3 Although the Er:YAG 1 and Er,Cr:YSGG 3 lasers have been recommended for root instrumentation, to our knowledge there are no studies reporting a direct comparison between these tools.…”

“…[1][2][3] Additionally, manual scaling produces a smear layer, which in turn may be related to a lower initial stability of the clot on the root surface, which marks the initial process of periodontal regeneration. 4 Among the high-intensity lasers, Er:YAG (2.94 µm) and Er,Cr:YSGG (2.78 µm) lasers are the most suitable for laser irradiation on root surfaces. The wavelength of these lasers is well absorbed by water molecules; therefore, irradiation with these lasers promotes water heating in the hydroxyapatite crystals, causing a sudden evaporation of water and microbursts in the interprisDeclaration of Interests: The authors certify that they have no commercial or associative interest that represents a conflict of interest in connection with the manuscript.…”

The aim of this study was to conduct an in vitro evaluation, by scanning electron microscopy (SEM), of the adhesion of blood components on root surfaces irradiated with Er,Cr:YSGG (2.78 µm) or Er:YAG (2.94 µm) laser, and of the irradiation effects on root surface morphology. Sixty samples of human teeth were previously scaled with manual instruments and divided into three groups of 20 samples each: G1 (control group) -no treatment; G2 -Er,Cr:YSGG laser irradiation; G3 -Er:YAG laser irradiation. After performing these treatments, blood tissue was applied to 10 samples of each group, whereas 10 samples received no blood tissue application. After performing the laboratory treatments, the samples were observed under SEM, and the resulting photomicrographs were classified according to a blood component adhesion scoring system and root morphology. The results were analyzed statistically (Kruskall-Wallis and Mann Whitney tests, α = 5%). The root surfaces irradiated with Er:YAG and Er,Cr:YSGG lasers presented greater roughness than those in the control group. Regarding blood component adhesion, the results showed a lower degree of adhesion in G2 than in G1 and G3 (G1 × G2: p = 0.002; G3 × G2: p = 0.017). The Er:YAG and Er,Cr:YSGG laser treatments caused more extensive root surface changes. The Er:YAG laser treatment promoted a greater degree of blood component adhesion to root surfaces, compared to the Er,Cr:YSGG treatment.

“…These interactions accelerate the process of periodontal regeneration. 18 SEM analysis of specimens subjected to laser irradiation (100 and 150 mJ) and SRP with manual curettes revealed variable degrees of changes in root surfaces. These results were in accordance with the findings of de Oliveira et al 19 They reported that all root surfaces irradiated with erbium, chromium doped yttrium scandium gallium garnet (Er-Cr: YSGG) laser were rougher than non-lased surfaces (similar to our study).…”

Please cite this article as follows: Amid R, Gholami GA, Mojahedi M, Aghalou A, Gholami M, Mirakhori M. Effects of root debridement with hand curettes and Er:YAG laser on chemical properties and ultrastructure of periodontally-diseased root surfaces using spectroscopy and scanning electron microscopy. J Lasers Med Sci. 2017;8(2):66-71. doi:10.15171/jlms.2017.12. IntroductionPeriodontal diseases are among the most common infectious diseases caused by the accumulation of bacterial plaque on tooth surfaces. Periodontitis can result in soft and hard tissue destruction and eventual tooth loss. Scaling and root planning with hand instruments, sonic and ultrasonic devices and air abrasion are performed for treatment of periodontal diseases.1 Nonsurgical periodontal debridement is performed aiming to efficiently eliminate plaque and calculus without damaging root surfaces. Manual instruments and ultrasonic devices have long been used for scaling and root planing (SRP) with successful results. 2Dental lasers were recently introduced to increase the efficacy of conventional SRP, and many studies have evaluated their efficacy in enhancing the biocompatibility and attachment of fibroblasts to root surfaces. 3 The efficacy of erbium-doped yttrium aluminum garnet (Er:YAG) laser The efficacy of erbium-doped yttrium aluminum garnet (Er:YAG) laser for root debridement in comparison with curettes has been the subject of many recent investigations. Considering the possibility of chemical and ultra-structural changes in root surfaces following laser irradiation, this study sought to assess the effects of scaling and root planing (SRP) with curettes and Er:YAG laser on chemical properties and ultrastructure of root surfaces using spectroscopy and scanning electron microscopy (SEM). Methods: In this in vitro experimental study, extracted sound human single-rooted teeth (n = 50) were randomly scaled using manual curettes alone or in conjunction with Er:YAG laser at 100 and 150 mJ/pulse output energies. The weight percentages of carbon, oxygen, phosphorous and calcium remaining on the root surfaces were calculated using spectroscopy and the surface morphology of specimens was assessed under SEM. Data were analyzed using one-way analysis of variance (ANOVA). Results: No significant differences (P > 0.05) were noted in the mean carbon, oxygen, phosphorous and calcium weight percentages on root surfaces following SRP using manual curettes with and without laser irradiation at both output energies. Laser irradiation after SRP with curettes yielded rougher surfaces compared to the use of curettes alone. Conclusion: Although laser irradiation yielded rougher surfaces, root surfaces were not significantly different in terms of chemical composition following SRP using manual curettes with and without Er:YAG laser irradiation. Er:YAG laser can be safely used as an adjunct to curettes for SRP.
