To systematically review the current evidence on the relationship between dentition status and chewing ability in older adults, as the latter was subjectively perceived by questionnaires.
Tooth loss is associated with functional impairment regarding chewing ability, depending on the number and the location of the remaining teeth.
A search of the English literature was undertaken using the appropriate electronic databases and keywords in order to answer the question of this review. Independent extraction of the related articles was carried out by two authors using predefined eligibility criteria.
Full-text analysis was performed for 51 articles of possible relevance. Finally, data were extracted from 18 studies, published in 20 articles that met the inclusion criteria.
Although there was a conflict between the studies relevant to the number of functional tooth units needed to maintain adequate oral function, it was revealed that chewing ability was closely related to the number and distribution of teeth remaining. Treatment plan should focus on the preservation of the strategic parts of the dental arch that are critical for adequate oral function. Long-term prospective studies, comprising well-defined criteria, clinical variables, methods and utilising comprehensive questionnaires, should be preferred to obtain a clearer picture on the association between masticatory ability and functional tooth units.
鉴于老年人的咀嚼能力是通过问卷调查主观感知的，本研究旨在系统回顾当前关于老年人牙列状况与咀嚼能力之间关系的证据。
牙齿缺失与咀嚼能力的功能损害有关，这取决于剩余牙齿的数量和位置。
通过使用适当的电子数据库和关键词检索英文文献，以回答本综述的问题。两位作者使用预先定义的纳入标准独立提取相关文章。
对51篇可能相关的文章进行了全文分析。最后，从18项研究中提取数据，这些研究发表在20篇符合纳入标准的文章中。
尽管在维持足够口腔功能所需的功能性牙单位数量相关研究之间存在冲突，但研究表明咀嚼能力与剩余牙齿的数量和分布密切相关。治疗计划应侧重于保留对足够口腔功能至关重要的牙弓关键部位。为了更清楚地了解咀嚼能力与功能性牙单位之间的关联，应优先进行长期前瞻性研究，这些研究应包含明确的标准、临床变量、方法并使用综合问卷。
