To evaluate systematically the influence of sex of dental professionals on their capability for visual color matching.
The protocol was registered on PROSPERO (CRD42020205393). PICOS question was develop based on the population, intervention, comparison, outcomes, and study design (PICOS). Eligibility criteria included cross section studies, randomized clinical trials and cohort studies that compared the effect of sex on the visual color matching process. Five electronic databases (Pubmed, Cochrane, EMBASE, Medline, and SCOPUS) and additional literature were screened independently by two researchers in July 2020. Clinical studies evaluating visual color matching skills of dental professionals were included. Studies that did not compare the difference between sexes were excluded. Duplicate articles were removed, titles and abstracts were screened, and studies were selected according to the inclusion criteria. Data were collected and reported in accordance with PRISMA guidelines. Risk of bias was assessed using Joanna Briggs Institute Critical Appraisal Tools.
A total of 1192 articles were screened from which 132 full text articles were analyzed and 37 finally included in the systematic review. Most of the studies evaluated the color matching abilities of dental students in vitro with shade tabs or extracted teeth. Out of the 37 articles included, 25 reported no significant difference in shade matching abilities between the sexes. Of the 12 studies that found a significant difference, 11 reported that females had better scores in shade matching exercises. For all studies a low risk of bias was revealed for most of the domains.
While the non-homogeneity of the settings and methods in the included studies make it impossible to construct aggregate statistic, this systematic review suggests that the sex is unlikely to be a critical factor influencing color matching abilities.
This study suggest that sex of dental professionals does not play a critical factor in matching satisfactory color of future dental restoration with surrounding teeth.
系统评估牙科专业人员性别的差异对其视觉比色能力的影响。
本研究方案已在 PROSPERO（CRD42020205393）上注册。基于人群、干预、比较、结局和研究设计（PICOS）制定了 PICOS 问题。纳入标准包括横断面研究、随机临床试验和队列研究，这些研究比较了性别的差异对视觉比色过程的影响。于 2020 年 7 月，两名研究人员独立筛选了 5 个电子数据库（PubMed、Cochrane、EMBASE、Medline 和 SCOPUS）和其他文献。纳入评估牙科专业人员视觉比色技能的临床研究。排除未比较性别差异的研究。去除重复文章，筛选标题和摘要，并根据纳入标准选择研究。按照 PRISMA 指南收集和报告数据。使用 Joanna Briggs 研究所的批判性评估工具评估偏倚风险。
共筛选出 1192 篇文章，其中 132 篇全文进行了分析，最终有 37 篇纳入系统评价。大多数研究通过比色板或提取的牙齿在体外评估牙科学生的比色能力。在纳入的 37 篇文章中，25 篇报道性别之间在比色匹配能力上无显著差异。在发现有显著差异的 12 项研究中，有 11 项研究报告女性在比色匹配练习中的得分更高。对于所有研究，大多数领域的偏倚风险较低。
尽管纳入研究的设置和方法存在非一致性，使得无法构建综合统计数据，但本系统评价表明，性别不太可能是影响比色能力的关键因素。
本研究表明，牙科专业人员的性别在匹配未来牙科修复体与周围牙齿的满意颜色方面并非关键因素。
