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.

“…43 Bu olumlu özelliklerinin yanında yapılan çalışmalarda lazerlerin pürüzlendirme amacıyla kullanımının asitle pürüzlendirmeye alternatif olamayacağı, adezivlerin bağlanma dayanımı açısından başarılı sonuçlar vermediği bildirilmiştir. 44,45 Bu çalışmaların aksine, Sallam ve arkadaşlarının 46 Er:YAG laser kullanarak yaptıkları çalışmada %37'lik fosforik asit ve lazer ile pürüzlendirme yapılmıştır. Çalışmanın sonucunda iki grup arasında braketlerin bağlanma dayanımı açısından istatistiksel olarak anlamlı bir fark olmadığı, lazerin asitle pürüzlendirmeye alternatif bir yöntem olabileceği bulunmuştur.…”

Öz Diş hekimliğinde lazerlerin kullanımı; teşhis amaçlı olarak, koruyucu diş hekimliği uygulamalarında, çürük temizleme ve kök kanal preparasyonu gibi sert doku uygulamalarında, insizyon, gingivektomi (diş etinin kesilmesi ve düzeltilmesi) ve hemostazın sağlanması gibi yumuşak doku uygulamalarında giderek yaygınlaşmaktadır. Yapılacak olan işleme göre tercih edilecek lazer tipi ve uygun parametreler değişmektedir. Lazerler; aktif maddesine, çalışma yöntemine, dalga boyuna ve enerjisine göre sınıflandırılırlar. Diş hekimliği alanında en sık tercih edilen lazerler argon, diyot, Nd: YAG, CO 2 , Er: YAG ve Er: Cr; YSGG lazerlerdir. Erişkinlerde olduğu gibi çocuklarda da güvenle kullanılabilmelerine rağmen, bazen çocuk hastalarda kullanımlarına dair tereddütler bulunabilmektedir. Bu derlemenin amacı, çocuk diş hekimliği alanında lazerlerin kullanım amaçlarını, avantaj ve dezavantajlarını belirtmek; çocuklarda ve süt dişleri üzerinde yapılan güncel çalışmaları da derleyerek bu konudaki bilgi düzeyini arttırmaktır.

“…Studies show that the use of laser etching to bond orthodontic brackets yields excellent bond strength in a significantly lesser time when compared to the conventional technique. [ 6 ] There are studies determining the efficacy of irradiation of enamel with Erbium, chromium: yttrium–scandium–gallium–garnet laser of different output powers (0.5 W, 0.75 W, 1 W, 1.5 W, 1.75 W, and 2 W) with a constant duration time of 15 s for orthodontic bonding. The results show that comparable mean shear bond strength and enamel surface etching can be obtained with Er, Cr:YSGG laser (operated at 1.5 W, 1.75 W, and 2 W for 15 s) as with acid etching.…”

BACKGROUND: Laser etching addresses the disadvantages of conventional acid etching technique, such as enamel decalcification and formation of white spot lesions. The aim of the present study was to evaluate and compare the shear bond strength (SBS), adhesive remnant index (ARI), and the surface characteristics of the samples treated with conventional acid etching and Er, Cr: YSGG laser etching with variable output power and time durations. METHODOLOGY: The study sample included 78 extracted teeth divided into six groups of 13 teeth each, and 3 samples from each group were utilized for analyzing etch patterns, and the remaining 10 teeth from each group were used for evaluating the shear bond strength. In Group I phosphoric acid etching was done, whereas in Group II– VI Laser etching 1.5 W/10 s, 1.5 W/15 s, 3 W/5 s, 3 W/10 s, 3 W/15 s. Statistical analysis for shear bond strength testing was performed using one-way ANOVA followed by Post HOC tests. RESULTS: The mean shear bond strength of Group I was 7.16 Mpa and Group III of 5.43 Mpa. Group II, IV, V, and VI had mean shear bond strength of 4.93 Mpa, 3.88 Mpa, 4.05 Mpa, and 4.88 Mpa, respectively. The ARI scores Group I had a significant number of samples with scores 2 other groups showed increased Score 0. The etch pattern of groups I, II, III showed the combined dissolution of both prism cores, and peripheries were seen. In group IV, the etching pattern was irregular with the pitted type of surface. In groups V and VI, relatively flat and smooth enamel surface was seen. CONCLUSION: The bond strength attained by laser etching (1.5 W/10 s and 1.5 W/15 s) was comparable to that obtained by the acid etching technique.
