The purpose of this study was to identify systematic reviews (SRs) that compared laser with other dental restorative procedures and to evaluate their methodological quality. A search strategy was developed and implemented for MEDLINE, the Cochrane Library, LILACS, and the Brazilian Dentistry Bibliography (1966- 2007). Inclusion criteria were: the article had to be an SR (+/- meta-analysis); primary focus was the use of laser in restorative dentistry; published in English, Spanish, Portuguese, Italian, German. Two investigators independently selected and evaluated the SRs. The overview quality assessment questionnaire (OQAQ) was used to evaluate methodological quality, and the results were averaged. There were 145 references identified, of which seven were SRs that met the inclusion criteria (kappa=0.81). Of the SRs, 71.4% appraised lasers in dental caries diagnosis. The mean overall OQAQ score was 4.4 [95% confidence interval (CI) 2.4- 6.5]. Of the SRs, 57.1% had major flaws, scoring < or = 4. SR methodological quality is low; therefore, clinicians should critically appraise them prior to considering their recommendations to guide patient care.
本研究旨在识别比较激光与其他牙科修复程序的系统评价（SRs），并评估其方法学质量。制定并实施了一项针对 MEDLINE、Cochrane 图书馆、LILACS 和巴西牙科文献（1966-2007 年）的检索策略。纳入标准为：文章必须为 SR（+/- 荟萃分析）；主要重点是激光在修复牙科中的应用；以英文、西班牙文、葡萄牙文、意大利文和德文发表。两名研究者独立选择和评估了 SRs。使用概述质量评估问卷（OQAQ）评估方法学质量，并计算平均值。共确定了 145 篇参考文献，其中 7 篇为符合纳入标准的 SRs（kappa=0.81）。在这些 SRs 中，71.4%评估了激光在龋齿诊断中的应用。总体 OQAQ 得分平均值为 4.4 [95%置信区间（CI）为 2.4-6.5]。其中，57.1%的 SRs 存在重大缺陷，得分<或=4。SR 的方法学质量较低；因此，临床医生在考虑其建议以指导患者护理之前，应仔细评估它们。
