The COVID-19 pandemic impacted every area of our lives, including delaying urgent dental care. However, studies evaluating how patients using dental prostheses have been affected by the pandemic are lacking.
The purpose of this study was to investigate how patients using different types of dental prostheses were being affected by the COVID-19 pandemic.
A total of 129 randomly selected individuals from among those who had been examined in the same clinic before the COVID-19 outbreak were included in the study. The study participants were divided into 4 groups according to their type of prosthesis: complete dentures, implant-retained removable dentures, tooth-supported fixed partial dentures, and implant-supported fixed partial dentures. The Oral Health Impact Profile (OHIP-14) questionnaire was implemented by telephone interviews with the study participants, who were also asked about their concerns and steps made regarding prosthetic hygiene during the COVID-19 pandemic. Data were evaluated by the Kruskal-Wallis and post hoc Dunn tests, and multivariate logistic regression analysis with forward selection was carried out to identify predictors of the oral health-related quality of life (OHRQoL) status (α=.05).
OHIP-14 total scores did not vary significantly among the groups (P>.05). When the domain scores of OHIP-14 were considered separately, the analysis revealed that the implant-retained removable denture group had significantly poorer functional limitations when compared with the tooth-supported fixed partial denture (P=.005) and implant-supported fixed partial denture (P=.031) groups. The results of the multivariate logistic regression analysis indicated a statistically significant association between OHRQoL during the COVID-19 pandemic and the frequency of tooth or denture cleaning (1 time a day versus less than 1 time a day: P=.011; 2-3 times a day versus less than 1 time a day: P=.032).
All prosthesis users exhibited increased interest in dental hygiene and an increase in the frequency of prosthesis cleaning during the pandemic. Furthermore, the study determined that the frequency of tooth or denture cleaning was associated with significantly improved OHRQoL during the time of the COVID-19 pandemic. Among the denture groups, those treated with implant-retained removable dentures had the poorest functional limitation in terms of OHRQoL, which can be linked to postponement of routine maintenance appointments. Therefore, providing all patients with scientifically sound information on prosthetic care during a pandemic would be highly beneficial.
COVID-19 大流行影响了我们生活的方方面面，包括延迟紧急牙科护理。然而，评估使用牙科修复体的患者受到大流行影响的研究还很少。
本研究旨在调查使用不同类型牙科修复体的患者受到 COVID-19 大流行的影响。
从 COVID-19 爆发前在同一家诊所接受检查的 129 名随机个体中选取研究对象。根据修复体类型，将研究对象分为 4 组：全口义齿、种植体支持可摘局部义齿、牙支持固定局部义齿和种植体支持固定局部义齿。通过电话访谈对研究对象实施口腔健康影响量表（OHIP-14）问卷调查，询问他们在 COVID-19 大流行期间对义齿卫生的关注和采取的措施。采用 Kruskal-Wallis 和事后 Dunn 检验对数据进行评估，并进行带有向前选择的多变量逻辑回归分析，以确定与口腔健康相关的生活质量（OHRQoL）状况的预测因素（α=.05）。
OHIP-14 总分在各组间无显著差异（P＞.05）。当单独考虑 OHIP-14 的各域评分时，分析表明与牙支持固定局部义齿（P=.005）和种植体支持固定局部义齿（P=.031）组相比，种植体支持可摘局部义齿组的功能限制明显较差。多变量逻辑回归分析的结果表明，COVID-19 大流行期间的 OHRQoL 与义齿或牙齿清洁频率之间存在统计学显著关联（每天 1 次与每天少于 1 次：P=.011；每天 2-3 次与每天少于 1 次：P=.032）。
所有修复体使用者在大流行期间对口腔卫生的兴趣增加，并且增加了修复体清洁的频率。此外，研究确定义齿或牙齿清洁的频率与 COVID-19 大流行期间 OHRQoL 的显著改善相关。在义齿组中，使用种植体支持可摘局部义齿的患者在 OHRQoL 方面的功能限制最差，这可能与常规维护预约的推迟有关。因此，在大流行期间向所有患者提供有关义齿护理的科学信息将非常有益。
