“…26,27 In addition, Er:YAG laser etching was found to be painless and does not involve either vibration or heat, and the easy maneuvering of the laser apparatus is encouraging to use routinely in similar dental tasks (Usumez et al 2002), (Aglarci et al 2016). 9,13 In the present study, a higher sheer bond strength mean value was recorded in acid etching group (14.71) versus (9.11) for laser group (table 1, Fig.1). These values though seems less for laser group, still however efficient for orthodontic brackets optimal bond strength values lying between 6-8MPa.…”

“…When addressing laser etching of enamel, many authors suggested that the laser etching is capable of creating remineralization micro spaces that traps free ions and produces a surface that is more acid resistant and less susceptible to caries, as a result, it did not need water spraying or air drying saving precious chair time (sawan et al 2015), (Aglarci et al 2016). 12,13 On the other hand, where phosphoric acid etching has proven to be a reliable method of bonding resins to enamel, a potential disadvantage of enamel acid etching is demineralization of the most superficial layer, a matter of concern for every orthodontic practitioner. As a result of demineralization, the enamel surface is more susceptible to acid attack and caries (Nalçaci et al 2017).…”

Objectives: Comparing effect of surface enamel conditioning when irradiated with Er,Cr:YSGG laser versus typical phosphoric acid etching on shear bond strength of orthodontic brackets and their effect on esthetics of enamel surfaces after debonding. Methods: Forty freshly extracted premolars were used in this study. Sample was divided into two groups (n=20), group I; enamel etched with 37% phosphoric acid (3M Unitek, Monrovia, USA) for 15 s. Group II; enamel was irradiated with Er,Cr:YSGG laser ablated with an energy output of 4.5 watt/20hz (2.78 μm wavelength) used for 15 sec. Orthodontic brackets (NU-EDGE.022" ROTH RX.TP orthodontics) were bonded to enamel surface of all specimens (Feltik Supreme XT Flowable, 3M/ESPE). The teeth were placed in Lloyd universal testing machine at crosshead speed of 0.5 mm/minute, and the shear force to remove the brackets was recorded. The bracket bases and enamel surfaces were examined after debonding under a light stereomicroscope at 20 x magnification and the adhesive remnant index (ARI) scores were assigned to each specimen. Statistical analysis was conducted using SPSS. The SBS data were compared with an unpaired t test. Statistical significance for both tests was defined as p < 0.05. The distributions of ARI scores were compared with an unpaired t test. Results: A higher shear bond strength mean value was recorded in acid etching group (14.71±0.82) Mpa, where unpaired t test revealed that the difference between groups was statistically significant (P<0.0001). Higher (ARI) mean value was recorded in laser etching group (2.3±0.47), where unpaired t test revealed that the difference between groups was statistically significant (P<0.0001). Conclusions: Er:YAG laser is capable of obtaining optimal bond strength for orthodontic brackets when used as a surface conditioning agent though have lower bond strength, In addition, it leaves the enamel with a rougher surface upon debonding versus typical acid etching techniques.

“…ARI scores are used to evaluate residual adhesive conditions on enamel surfaces after laser treatment. It is found that the rate of teeth with ARI score ≤2 in Er:YAG laser etching group was obviously higher than phosphoric acid etching group [1,15,18,41] of (OR = 10.21, 95% CI range: 2.76–37.85, P < .05, 96.77% vs 69.35%), showed that Er:YAG laser was better than acid etching for cleaning teeth after debonding. Similarly, the rate of teeth with ARI score ≤2 in Er,Cr:YSSG laser was also higher than in the acid group on enamel etching (OR = 3.70, 95% CI range: 1.15–11.88, P < .05, 87.5% vs 67.5%) based on 3 studies, [42–44] indicated that less adhesive left on the enamel surface.…”

“…[ 14 – 17 ] However, using acid etching technique, the enamel surface becomes prone to acid attack if it is not completely filled with adhesive. [ 18 , 19 ] Besides, acid etching technique increases the caries susceptibility of the enamel, increases enamel demineralization [ 1 , 20 , 21 ] and results in dissolution of the enamel subsurface.

Background: Recently, laser etching has appealed to people’s attention. It is meaningful to compare the effect of erbium-doped yttrium-aluminum-garnet (Er:YAG) and erbium-chromium; yttrium-scandium-gallium-garnet (Er,Cr:YSSG) laser etching parameters with acid etching on bond strength of enamel surfaces. As far as we know, there still remains no related meta-analysis. To evaluate the efficacy of Er:YAG and Er,Cr:YSSG lasers etching on shear bond strength (SBS) of brackets bonded to enamel. The meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, conducted with literature search. Methods: Twelve relevant randomized controlled trials (RCTs) were included. Results: The pooled analysis of SBS showed that there were no significant differences between erbium family lasers and acid etching. In the mass, we noticed they did not achieve statistical significance in the lasers etching and acid etching. However, pooled analysis of 5 studies showed the SBS bonding to enamel was lower in Er,Cr:YAG laser group compared with acid group. As a whole, there were statistical significance between erbium lasers groups and acid etching group in adhesive remnant index (ARI) aspects, which less adhesives remained can reduce damage to enamel. With regard to the rate of teeth with ARI score ≤2, the results in Er:YAG laser etching group were obviously higher than acid etching group. Conclusion: Our data indicated that erbium lasers may be considered bonding of brackets to enamel instead of acid etching bonding to enamel.

Introduction: In dental practice, low-level laser therapy (LLLT) and high-intensity laser therapy (HILT) are mainly used for dental surgery and biostimulation therapy. Within the Orthodontic specialty, while LLLT has been widely used to treat pain associated with orthodontic movement, accelerate bone regeneration after rapid maxillary expansion, and enhance orthodontic tooth movement, HILT, in turn, has been seen as an alternative for addressing soft tissue complications associated to orthodontic treatment. Objective: The aim of this study is to discuss HILT applications in orthodontic treatment. Methods: This study describes the use of HILT in surgical treatments such as gingivectomy, ulotomy, ulectomy, fiberotomy, labial and lingual frenectomies, as well as hard tissue and other dental restorative materials applications. Conclusion: Despite the many applications for lasers in Orthodontics, they are still underused by Brazilian practitioners. However, it is quite likely that this demand will increase over the next years - following the trend in the USA, where laser therapies are more widely used.
