“…A.Actinomycesmcomitans has alsobeen found in atherosclerotic plaques, and there has been evidence to suggest that sub gingival A. Actinomycesmcomitans may be related to coronary heart disease.This makes it even more compelling to seek methods to control this aggressive pathogen [24].Laser soft tissue treatment for pericoronal infections has the effect on CFU which is clear in reducing bacterial loads. Due to its characteristics, as well as to other known advantages such as low cost and practicality, the diode laser has been compared to the other conventional methods [25].It has been subject of a diversity of studies intended to evaluate its potential in relation to its biocompatibility [26].…”

“…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.

“…22 Schwartz et al showed that the efficacy of calculus removal by Er:YAG laser irradiation in the clinical setting was similar to that of hand instruments; but, diode laser irradiation was not suitable for calculus removal due to significant surface distortion caused. 23 Frentzen et al reported increased loss of cementum and dentin and high surface roughness due to Er:YAG laser irradiation and questioned its clinical application. 24 On the other hand, de Mendonca et al in 2008 reported that SRP with manual curettes caused rougher surfaces than Er:YAG laser irradiation and ultrasonic scaler, and added that all methods increased root surface roughness after treatment.…”

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.
