The authors aimed to critically review the literature regarding the relationship between retention of teeth and oral health-related quality of life (OHRQoL) and the extent to which tooth retention can ensure OHRQoL among adults. The authors investigated studies that assessed the relationship between number of teeth and OHRQoL and how the position, type, and/or pattern of the teeth is related to OHRQoL. Relevant papers published in English from January 2004 to September 2015 were searched via PubMed and EMBASE. Twenty-nine papers-including cross-sectional, longitudinal, clinical trial, and case-control studies-were included and categorized according to 4 subthemes to achieve the stated aim: 1) number of teeth or missing teeth and OHRQoL, 2) occluding pairs or functional units and OHRQoL, 3) position of remaining or missing teeth and OHRQoL, and 4) shortened dental arches (SDAs) and OHRQoL. The main findings for each subtheme were as follows: 1) A significant association between number of teeth and OHRQoL was shown in most studies; however, those studies found different cutoff points regarding the number of teeth that affect OHRQoL, after adjusting for other factors in the analyses (e.g., age, sex, cultural background, and study locations). 2) The number of occluding pairs and the location of remaining teeth have great impacts on OHRQoL. 3) Having fewer anterior occluding pairs had a greater negative impact on aesthetics and thus affected OHRQoL. 4) Two randomized clinical trials on SDAs indicated that people with SDAs do not show worse OHRQoL than do those with removable dentures. The only 2 population-based studies on SDAs showed that adults with SDAs have no impaired OHRQoL when compared with those having more natural teeth. To conclude, this review found evidence that retention of teeth is associated with better OHRQoL. The number of occluding pairs and the location of remaining teeth have great impacts on OHRQoL. People with SDAs maintain an acceptable level of OHRQoL.
作者旨在批判性地回顾有关保留牙齿与口腔健康相关生活质量（OHRQoL）之间关系的文献，并评估保留牙齿在多大程度上可以确保成年人的 OHRQoL。作者研究了评估牙齿数量与 OHRQoL 之间关系的研究，以及牙齿的位置、类型和/或模式与 OHRQoL 的关系。通过 PubMed 和 EMBASE 搜索了 2004 年 1 月至 2015 年 9 月期间发表的英文相关论文。共纳入 29 篇论文，包括横断面研究、纵向研究、临床试验和病例对照研究，并根据 4 个亚主题进行分类，以实现既定目标：1）牙齿数量或缺失牙齿与 OHRQoL，2）咬合对或功能单位与 OHRQoL，3）残留或缺失牙齿的位置与 OHRQoL，以及 4）短牙弓（SDA）与 OHRQoL。每个亚主题的主要发现如下：1）大多数研究表明牙齿数量与 OHRQoL 之间存在显著关联；然而，在调整分析中的其他因素（例如年龄、性别、文化背景和研究地点）后，这些研究发现影响 OHRQoL 的牙齿数量存在不同的截止点。2）咬合对的数量和残留牙齿的位置对 OHRQoL 有很大影响。3）前牙咬合对数量较少对美观有更大的负面影响，从而影响 OHRQoL。4）两项关于 SDA 的随机临床试验表明，SDA 患者的 OHRQoL 并不比可摘义齿患者差。关于 SDA 的仅有的两项基于人群的研究表明，与拥有更多天然牙齿的成年人相比，SDA 成年人的 OHRQoL 没有受损。总之，本综述发现有证据表明保留牙齿与更好的 OHRQoL 相关。咬合对的数量和残留牙齿的位置对 OHRQoL 有很大影响。SDA 患者保持可接受的 OHRQoL 水平。
