This systematic review and meta-analysis aimed to assess how laser conditioning affected brackets bonded to dental ceramics' shear bond strength (SBS). The study was conducted by searching Pubmed/Medline, Scopus, Embase, Web of Science, the Cochrane Library, and Google Scholar up to September 14, 2022. In addition, the reference lists of the relevant articles were checked manually. Articles that compared SBS of laser-treated feldspathic, lithium disilicate, or zirconia surfaces with other standard techniques for bonding metal or ceramic orthodontic brackets were considered. Using a random-effects model, data pooling was carried out as the weighted mean difference (WMD). This study initially contained 1717 reports, and following review, 32 articles were deemed suitable for our meta-analysis. The pooling results showed that the treatments with lasers such as "Er:YAG" [WMD = -1.12 MPa; 95% confidence interval (CI): -1.93 to -0.31], "Er:YAG + Silane" (WMD = -3.08 MPa; 95% CI: -4.77 to -1.40), and "Nd: YAG + Silane" (WMD = -2.58 MPa; 95% CI: -3.76 to -1.40) had statistically significant lower adhesion values compared with controls. Contrarily, "Ti:Sapphire femtosecond" demonstrated significantly higher bonding values (WMD = 0.94 MPa; 95% CI: 0.29-1.60). In contrast, other interventions obtained no statistically significant difference in SBS. Most of the laser groups showed results comparable with those of conventional approaches. Although more research is necessary for definitive conclusions, laser treatment may be an effective option for treating the surfaces of ceramic materials.
本系统评价和荟萃分析旨在评估激光调处理如何影响黏结到牙科陶瓷的托槽的剪切结合强度 (SBS)。研究通过检索 Pubmed/Medline、Scopus、Embase、Web of Science、Cochrane 图书馆和 Google Scholar，截至 2022 年 9 月 14 日，同时还手动检查了相关文章的参考文献列表。纳入比较激光处理长石、二硅酸锂或氧化锆表面与其他用于黏结金属或陶瓷正畸托槽的标准技术的 SBS 的文章。使用随机效应模型，作为加权均数差 (WMD) 进行数据合并。本研究最初包含 1717 份报告，经过审查，有 32 篇文章适合我们的荟萃分析。合并结果表明，激光处理如 "Er:YAG" [WMD = -1.12 MPa；95%置信区间 (CI)：-1.93 至 -0.31]、"Er:YAG + 硅烷" (WMD = -3.08 MPa；95% CI：-4.77 至 -1.40) 和 "Nd:YAG + 硅烷" (WMD = -2.58 MPa；95% CI：-3.76 至 -1.40) 的黏附值与对照组相比具有统计学显著降低。相反，"Ti:Sapphire 飞秒" 显示出显著更高的黏合值 (WMD = 0.94 MPa；95% CI：0.29-1.60)。相比之下，其他干预措施在 SBS 方面没有统计学显著差异。大多数激光组的结果与传统方法相当。虽然需要更多的研究来得出明确的结论，但激光处理可能是治疗陶瓷材料表面的有效选择。
