The principal aim was to establish whether dental appearance affects employment prospects, and if so a secondary aim was to ascertain whether there is a difference between public-facing and non-public-facing jobs.
A prospective cross-sectional experimental analogue study.
Ninety undergraduates studying at London Metropolitan University School of Business.
Vignettes comprising curriculum vitae (CV) with a single photograph of the applicant attached formed the experimental manipulation. For each job application, the written information on the CV remained constant, but the attached photograph had one of three altered dental appearances: (1) aligned teeth, (2) maxillary stainless steel labial fixed appliance and (3) an absent maxillary left lateral incisor. To ascertain whether there are differences between public- and non-public-facing jobs, two different job descriptions with matching CVs were designed. Each participant was randomly assigned an envelope containing one CV with one photograph and asked if they would shortlist the candidate for an interview. Likert scales were used with higher scores indicating greater likelihood to shortlist. A Multivariate Analysis of Variance was conducted with Photo (three levels) and Job Type (two levels) as independent variables, and gender as a covariate.
A trend was found for the candidate with an absent maxillary lateral incisor to be less likely to be shortlisted for the public-facing job, compared to both candidates with aligned teeth and with fixed appliances. There were no significant main effects and the interaction was not significant. The effect of gender was not significant.
In this study, dental appearance did not influence employment prospects. When a photograph is attached to a CV, the dental appearance of the photograph did not influence whether a candidate was shortlisted for a job interview or their anticipated job performance. There were no differences between public-facing and non-public-facing jobs.
主要目的是确定牙齿外观是否会影响就业前景，如果是这样，次要目的是确定面向公众的工作和非面向公众的工作之间是否存在差异。
一项前瞻性横断面实验模拟研究。
90名在伦敦城市大学商学院学习的本科生。
vignettes由附有申请人单人照片的简历（CV）组成，形成实验操作。对于每份工作申请，简历上的书面信息保持不变，但所附照片有三种改变后的牙齿外观之一：（1）牙齿整齐，（2）上颌不锈钢唇侧固定矫治器，（3）上颌左侧侧切牙缺失。为了确定面向公众的工作和非面向公众的工作之间是否存在差异，设计了两种不同的工作描述并配以匹配的简历。每个参与者被随机分配一个信封，其中包含一份附有一张照片的简历，并被询问是否会将该候选人列入面试名单。使用李克特量表，得分越高表明列入面试名单的可能性越大。以照片（三个水平）和工作类型（两个水平）为自变量，性别作为协变量进行多变量方差分析。
发现与牙齿整齐和佩戴固定矫治器的候选人相比，上颌侧切牙缺失的候选人被列入面向公众工作面试名单的可能性较小。没有显著的主效应，交互作用也不显著。性别的影响不显著。
在本研究中，牙齿外观并未影响就业前景。当简历附有照片时，照片中的牙齿外观并未影响候选人是否被列入工作面试名单或他们预期的工作表现。面向公众的工作和非面向公众的工作之间没有差异。
