“…The bond strength measurements showed that teeth irradiated with diode laser reported higher bond strength than those irrigated with NaOCl/ EDTA, these results came in agreement with previous studies (23,24) , and another later study (25) that attributed it to the smear layer removal without significant loss in dentin mineral contents, but it came in contrast with other studies (26,27) that attributed it to inability to remove the smear layer that prevented the adhesion of sealer to the root canal.…”

The aim of this study was to assess and investigate the effect of diode laser on root canal disinfection, and root canal cleanliness, as well as its effect on the fracture resistance of tooth structure, and on the bond strength of resin sealer to the root canal wall. Materials and MethodsA total of 160 single rooted teeth were selected, and separated into two experimental groups (n=80), Group A were finally irrigated using 980 nm diode laser. Group B were finally irrigated using NaOCl/EDTA. Samples were evaluated for canal disinfection using the colony forming unit count, and Polymerase chain reaction. Samples were placed under scanning electron microscopic to evaluate the smear layer removal. A universal testing machine was used to test the resistance of teeth to fracture, and the bond strength of sealer to the root canal walls. ResultsGroup A showed higher bacterial reduction and better results in smear layer score than Group B. Also Group A presented higher fracture resistance than Group B, as well as better value of push out bond strength than Group B. ConclusionDiode laser is an efficient tool in bacterial reduction and smear layer removal when used as a final irrigation procedure, compared to NaOCl/EDTA.

“…This value is substantially higher than that obtained in this study, which may be attributable to the difference in the thickness of the discs used for the push-out test (4 mm in the F I G U R E 2 Representative scanning electron microscopic images of root-canal dentin surfaces after irrigation with ethylenediaminetetraacetic acid (EDTA), Irritrol, and QMix solutions activated manually and with diode and Er,Cr:YSGG lasers previous study) ( Alfredo et al, 2008). In another study, 980-nm diode laser activation of 17% EDTA increased the adhesion strength of an epoxy resin sealer in the middle thirds of bovine roots (Macedo et al, 2016). Several methodological differences, such as the use of bovine teeth and AH 26 root-canal filling paste, may explain the discrepancy between those results and the findings of the present study.…”

“…The push‐out test provides an effective and reliable measure of the adhesion of sealers to root canal walls, as it determines material dislocation resistance (Macedo et al, 2016) and causes failure in a manner that mimics clinical conditions (Carneiro et al, 2012). In this study, similar to the methods used in previous studies, sections for the push‐out test were obtained from only the middle third of each root (Gaddala, Veeramachineni, & Tummala, 2015; Ghabraei, Bolhari, Yaghoobnejad, & Meraji, 2017; Uzunoglu et al, 2015).…”

This study was conducted to evaluate the effects of ethylenediaminetetraacetic acid (EDTA), Irritrol, and QMix solutions used with manual irrigation and diode and erbium, chromium-doped yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser activation on the bonding ability of sealer to the intraradicular dentin. The root canals of 90 mandibular incisors were instrumented, and the teeth were allocated randomly to nine groups (n = 10/group) receiving final irrigation with different irrigation solutions (EDTA, Irritrol, and QMix) and irrigant activation techniques (manual, diode laser, and Er,Cr:YSGG laser). Following endodontic filling, three sections of 1-mm thickness were obtained from the middle third of each root. The root filling was subjected to a push-out test to examine the bond strength of the sealer to dentin. The test data were examined using analysis of variance with a significance level of ɑ < .05. Failure modes were determined by stereomicroscopy, and the surface characteristics of dentin were observed by scanning electron microscopy. Irritrol showed less push-out bond strength than did the other solutions in the Er,Cr:YSGG laser groups (p < .05). In the diode laser groups, QMix provided greater adhesion than did Irritrol (p < .05). The activation of QMix with the Er,Cr:YSGG laser increased the bond strength more than did manual irrigation (p < .05). No other significant difference was observed between other comparison pairs (p > .05). QMix provided adhesion superior to that of Irritrol when activated with diode and Er,Cr:YSGG lasers. Er,Cr: YSGG laser activation increased the adhesion of filling material with QMix irrigation.

“…Lasers have recently been applied to a variety of treatments in the field of dentistry, as evidenced by a number of clinical reports regarding caries treatment 1 and root tip resection 2 using the Er: YAG laser, pain relief using the CO 2 laser 3 and the diode laser, 4 and root treatment using the Nd: YAG laser. 5 It is used to relieve pain during tooth movement, temporomandibular joint pain, and stellate ganglion blocks. However, despite these reports, the detailed mechanisms underlying these treatments remain unknown.…”

Effect of Er: YAG Laser Irradiation on Bone Metabolism-Related Factors Using Cultured Human Osteoblasts

Introduction: A variety of laser treatments have been applied in numerous medical fields. In dentistry, laser treatments are used for caries, root canals, and periodontal disease, as well as surgical resection. Numerous reports have recently been published on the use of lasers for bone regeneration. If laser irradiation is found to promote the activation of bone metabolism, it might also be effective for periodontal treatment, peri-implantitis, and bone regeneration. Therefore, the present in vitro study aimed to elucidate the mechanisms underlying the effects of erbium-doped yttrium aluminum garnet (Er: YAG) laser irradiation on the bone using osteoblast-like cells. Methods: Osteoblast-like Saos 2 cells (5.0×104 cells) were seeded in 24-well plates. 24 hours after being seeded, the cells were subjected to 0.3 W, 0.6 W, and 2.0 W Er: YAG laser irradiation and then allowed to recover for 48 hours. The expression levels of bone metabolism-related factors alkaline phosphatase (ALP), bone sialoprotein (BSP), and osteoprotegerin (OPG) were then evaluated using reverse transcription–quantitative polymerase chain reaction and western blot analyses. Results: Saos 2 cells subjected to Er: YAG laser irradiation at 0.3 W, 0.6 W, and 2.0 W showed normal growth. When the Er: YAG laser irradiation and control groups were compared after 48 hours, increases were observed in ALP, BSP, and OPG gene and protein expression in the 2.0 W group. Similar results were obtained in the western blot analysis. Conclusion: These findings suggest that the Er: YAG laser irradiation of osteoblast-like cells is effective for activating bone metabolism factors.
