The main objective of the present study was to make a systematic review of how antioxidant agents affect shear bond strength of tooth-colored restorative materials after bleaching.
Electronic search was used to extract the related articles on the targeted key words such as "antioxidant", "dental bleaching" and "shear bond strength" (SBS) from MeSH, PubMed, Medline, and Cochrane electronic data bases. These articles were all published before 2016.
Inclusion criteria were restricted to English journal articles concerning humans, clinical trials, cohorts and case-control studies. Therefore, systematic reviews, case reports, letters to editors, editorials and congress abstracts were excluded from the analysis.
Most studies conducted on the issue have produced experimental data which are rather controversial, and there is no general agreement about the reported outcomes. As an illustration, most studies have not considered the relationship between the type of antioxidant materials and the shear bond strength. In point of fact, some researchers (e.g Kimyai et al.) have concluded that antioxidants like gel and solution leave similar effects on SBS. Alternatively, certain studies (e.g., Kunt et al.) have produced inconclusive data regarding the impact of one week postponement of the restorative process on SBS after the bleaching process. The results of the studies evaluating the role of various adhesive systems used after bleaching have demonstrated that regardless of the type of adhesive system used, applying antioxidants before restorative procedures can adversely affect the bleaching agents utilized for SBS. It has also been suggested that the type of the adhesive system used might be correlated with the magnitude of SBS. The results obtained from the systematic review of the articles under investigation reflected that the use of antioxidant agents, regardless of their type, form, concentration and duration of application, can improve SBS after bleaching.
本研究的主要目的是系统综述抗氧化剂对漂白后牙齿色修复材料剪切粘结强度的影响。
通过电子检索从医学主题词表（MeSH）、PubMed、Medline和Cochrane电子数据库中提取有关“抗氧化剂”、“牙齿漂白”和“剪切粘结强度”（SBS）等目标关键词的相关文章。这些文章均发表于2016年之前。
纳入标准仅限于涉及人类的英文期刊文章、临床试验、队列研究和病例对照研究。因此，系统评价、病例报告、给编辑的信、社论和会议摘要被排除在分析之外。
关于该问题的大多数研究得出的实验数据颇具争议，且对报告结果尚无普遍共识。例如，大多数研究未考虑抗氧化材料类型与剪切粘结强度之间的关系。事实上，一些研究人员（如Kimyai等人）得出结论，凝胶和溶液等抗氧化剂对SBS的影响相似。另外，某些研究（如Kunt等人）得出的关于漂白后修复过程推迟一周对SBS影响的数据尚无定论。评估漂白后使用的各种粘结系统作用的研究结果表明，无论使用何种粘结系统类型，在修复程序前应用抗氧化剂都会对用于SBS的漂白剂产生不利影响。也有人提出，所用粘结系统的类型可能与SBS的大小相关。对所研究文章进行系统综述得到的结果反映，无论抗氧化剂的类型、形式、浓度和应用持续时间如何，其使用均可提高漂白后的SBS。
