Several studies have investigated the effect of bleaching on dental tissues. The evaluation of the effect of home bleaching with 10% carbamide peroxide is important for assessing alterations in enamel microhardness that may affect dental health in terms of resistance to masticatory forces. This meta-analysis was performed in order to determine scientific evidence regarding the effects of home vital bleaching with 10% carbamide peroxide gel on the microhardness of human dental enamel. A systematic electronic literature search was conducted in the PubMed and Web of Science databases using search terms. Two independent researchers evaluated the information and methodological quality of the studies. Inclusion and exclusion criteria were established for article selection; further, only studies published in English were selected. Thirteen studies that met all of the inclusion and exclusion criteria were selected and underwent statistical analysis. The results of this meta-analysis showed no significant changes in enamel microhardness when using the 10% carbamide peroxide bleaching gel over periods of 7, 14 and 21 days.
多项研究调查了漂白对牙齿组织的影响。评估10%过氧化脲家庭漂白的效果对于评估牙釉质显微硬度的变化很重要，这种变化可能会在咀嚼力抵抗力方面影响牙齿健康。进行这项荟萃分析是为了确定关于使用10%过氧化脲凝胶进行家庭活髓漂白对人牙釉质显微硬度影响的科学证据。使用检索词在PubMed和科学网数据库中进行了系统的电子文献检索。两名独立研究人员评估了研究的信息和方法质量。为文章选择制定了纳入和排除标准；此外，只选择了英文发表的研究。选择了13项符合所有纳入和排除标准的研究并进行了统计分析。这项荟萃分析的结果表明，在7天、14天和21天的时间内使用10%过氧化脲漂白凝胶时，牙釉质显微硬度没有显著变化。
