The purpose of this review is to systematically assess the existing literature and summarize the evidence regarding the effect of erbium-doped yttrium aluminum garnet (Er:YAG) laser on enamel surface roughness and pulp health compared with the conventional orthodontic debonding techniques. Following the preferred reporting items for systematic reviews (Preferred Reporting Items for Systematic Reviews and Meta-analyses) statement, the electronic database, PubMed, Scopus, Web of Science, Google scholar, and Saudi Digital Library were searched for relevant published records. Data were collected following specific keywords: "debonding" "Er:YAG laser" etc. studies, and clinical randomized- and nonrandomized-controlled studies limited to the English language and published in peer-reviewed journals were included. A total of 564 articles were identified as relevant to the topic. Duplicates were excluded resulting in 382 articles, out of which 374 articles were discarded upon screening titles and abstracts. The remaining eight articles were read to their entirety and included in the current qualitative review after fulfilling the eligibility criteria. In all the included studies, a total of 480 sound posterior teeth were used to evaluate the effect of Er:YAG laser on debonding of orthodontic brackets from the enamel surface. Er:YAG laser debonding has demonstrated a reduced risk of enamel damage (fracture or cracks) but resulted in increased enamel surface roughness and was time-consuming for adhesive removal procedures compared with the conventional debonding methods. Further, within the applied laser settings, Er:YAG lasers have found to exhibit low thermal exhaustion in relation to the pulp. The laser source with a wavelength of 2940 nm has been used with different setting ranges (power of 2.5-5 W, energy 125-600 mJ, frequency 4-30 Hz, and pulse duration 50-350 μsec) for debonding of orthodontic brackets.
本综述的目的是系统评估现有文献，并总结关于铒石榴石激光（Er:YAG）对釉质表面粗糙度和牙髓健康影响的证据，与传统正畸去粘接技术进行比较。根据系统评价的首选报告项目（系统评价和荟萃分析的首选报告项目）声明，电子数据库 PubMed、Scopus、Web of Science、Google scholar 和沙特数字图书馆被用于搜索相关的已发表记录。数据是按照特定的关键词“去粘接”“Er:YAG 激光”等收集的。研究对象包括仅限于英语且发表在同行评议期刊上的临床随机和非随机对照研究。共有 564 篇文章与该主题相关。剔除重复后，有 382 篇文章，其中 374 篇文章在筛选标题和摘要时被剔除。其余 8 篇文章被全文阅读，并在满足纳入标准后纳入当前的定性综述。在所有纳入的研究中，共有 480 颗健康的后牙用于评估 Er:YAG 激光对正畸托槽从釉质表面去粘接的效果。与传统去粘接方法相比，Er:YAG 激光去粘接显示出降低釉质损伤（断裂或裂缝）风险的优势，但会导致釉质表面粗糙度增加，且去除粘接剂的程序耗时较长。此外，在应用的激光设置中，与牙髓相比，Er:YAG 激光表现出低的热耗竭。波长为 2940nm 的激光源已用于不同的设置范围（功率 2.5-5W，能量 125-600mJ，频率 4-30Hz，脉冲持续时间 50-350μsec），用于正畸托槽的去粘接。
