Abstract

Background: Smile attractiveness is a primary factor for patients to seek orthodontic treatment, however, there is yet no systematic evaluation of this topic in the literature.

Objectives: To assess the current evidence on the effect of orthodontic treatment on smile attractiveness.

Search methods: Seven electronic databases (MEDLINE, Cochrane Library, Virtual Health Library, SCOPUS, Web of Science, Google Scholar and Embase) were searched on 14 September 2022.

Selection criteria: Studies evaluating smile attractiveness before and after orthodontic treatment or only after completion of orthodontic treatment.

Data collection and analysis: Extracted data included study design and setting, sample size and demographics, malocclusion type, treatment modality and method for outcome assessment. Risk of bias was assessed with the ROBINS-I tool for non-randomised studies. Random-effects meta-analyses of mean differences and their 95% confidence intervals (CIs) were planned a priori.

Methods: After elimination of duplicate studies, data extraction and risk of bias assessment according to the Cochrane guidelines, an evaluation of the overall evidence was performed. The included studies were evaluated based on the characteristics of their study and control groups and based on their main research question. Also, all outcome measures were standardized into a common assessment scale (0-100), in order to obtain more easily interpretable results.

Results: Ten studies were included in this review, nine of which were assessed as being at serious risk of bias and one at moderate risk of bias. The large heterogeneity between the included studies did not allow for a meta-analysis. Orthodontic treatment has a moderately positive effect on smile attractiveness. When compared to no treatment, orthodontic treatment with premolar extractions improves smile attractiveness by 22%. Also, surgical correction of Class III cases increases smile attractiveness by 7.5% more than camouflage treatment. No other significant differences were shown between different types of treatment.

Conclusion: Based on the available data, orthodontic treatment seems to moderately improve the attractiveness of the smile. There is significant bias in the current literature assessing the effect of orthodontics on smile attractiveness; therefore, the results cannot be accepted with certainty.

正畸治疗对微笑吸引力的影响:系统性综述。
背景:微笑的吸引力是患者寻求正畸治疗的首要因素:微笑吸引力是患者寻求正畸治疗的首要因素,然而,目前尚无文献对这一主题进行系统评估:评估正畸治疗对微笑吸引力影响的现有证据:检索方法:于 2022 年 9 月 14 日检索了七个电子数据库(MEDLINE、Cochrane Library、Virtual Health Library、SCOPUS、Web of Science、Google Scholar 和 Embase):数据收集与分析:提取的数据包括研究设计和环境、样本量和人口统计学、错颌畸形类型、治疗方式和结果评估方法。采用ROBINS-I工具对非随机研究的偏倚风险进行评估。对平均差异及其 95% 置信区间(CIs)进行随机效应荟萃分析是事先计划好的:根据 Cochrane 指南剔除重复研究、提取数据并评估偏倚风险后,对总体证据进行评估。根据研究组和对照组的特点以及主要研究问题对纳入的研究进行了评估。此外,为了获得更易于解释的结果,还将所有结果测量标准化为一个通用的评估量表(0-100):本综述共纳入 10 项研究,其中 9 项被评估为存在严重偏倚风险,1 项存在中度偏倚风险。由于所纳入的研究之间存在较大的异质性,因此无法进行荟萃分析。正畸治疗对微笑的吸引力有适度的积极影响。与不进行治疗相比,拔除前磨牙的正畸治疗可将微笑吸引力提高 22%。此外,对 III 类病例进行手术矫正比伪装治疗可提高微笑吸引力 7.5%。不同类型的治疗之间没有其他明显差异:根据现有数据,正畸治疗似乎能适度提高微笑的吸引力。在评估正畸对微笑吸引力的影响方面,目前的文献存在很大的偏差;因此,不能肯定地接受这些结果。

期刊介绍: Progress in Orthodontics is a fully open access, international journal owned by the Italian Society of Orthodontics and published under the brand SpringerOpen. The Society is currently covering all publication costs so there are no article processing charges for authors. It is a premier journal of international scope that fosters orthodontic research, including both basic research and development of innovative clinical techniques, with an emphasis on the following areas: • Mechanisms to improve orthodontics • Clinical studies and control animal studies • Orthodontics and genetics, genomics • Temporomandibular joint (TMJ) control clinical trials • Efficacy of orthodontic appliances and animal models • Systematic reviews and meta analyses • Mechanisms to speed orthodontic treatment Progress in Orthodontics will consider for publication only meritorious and original contributions. These may be: • Original articles reporting the findings of clinical trials, clinically relevant basic scientific investigations, or novel therapeutic or diagnostic systems • Review articles on current topics • Articles on novel techniques and clinical tools • Articles of contemporary interest
