Onset of fever is a common presentation of symptoms in older adults. Loss of posterior teeth occlusion provokes dysphagia, which is commonly related to infectious diseases of the respiratory tract. However, a correlation between posterior teeth occlusion and the onset of fever has not been studied. The aim of the present study was to investigate whether posterior teeth occlusion is correlated with the onset of fever in residents of aged person welfare facilities.
This perspective cohort study was carried out from February 2019 to December 2019 in Kitakyushu, Japan. The follow-up period was 8 months. Overall, 141 residents aged ≥ 65 years from 10 aged person welfare facility were included. Dates when the body temperatures of participants were more than 37.2°C were recorded. Posterior teeth occlusion was evaluated by assessing functional tooth units (FTUs).
Data from 100 participants [median age, 89 (67-102)] were used for analysis. Total of 53 participants got a fever. The Kaplan-Meier analysis showed that the average period until onset of fever in participants with scores 0, 1-11 and 12 for FTU was 7.7 ± 0.6, 7.4 ± 1.0 and 3.9 ± 1.0, respectively. Cox's proportional hazards regression model revealed that participants with FTU = 0 were at higher risk of fever compared with those with FTU = 12 (hazards ratio: 3.2, 95% confidence interval: 1.4-7.7), adjusted for possible confounders.
Posterior teeth occlusion correlated with the risk of fever in older residents of nursing homes.
发热是老年人常见的症状表现。后牙缺失会引发吞咽困难，这通常与呼吸道传染病有关。然而，后牙缺失与发热之间的相关性尚未得到研究。本研究旨在调查养老院居民的后牙缺失是否与发热的发生有关。
这是一项前瞻性队列研究，于 2019 年 2 月至 2019 年 12 月在日本北九州市进行。随访时间为 8 个月。共有来自 10 家养老院的 141 名年龄≥65 岁的居民参与了本研究。记录参与者体温超过 37.2°C 的日期。通过评估功能性牙单位（FTUs）来评估后牙缺失情况。
对 100 名参与者（中位年龄 89 岁[67-102 岁]）的数据进行了分析。共有 53 名参与者发热。Kaplan-Meier 分析显示，FTU 评分为 0、1-11 和 12 的参与者发热的平均时间分别为 7.7±0.6、7.4±1.0 和 3.9±1.0。Cox 比例风险回归模型显示，FTU=0 的参与者发热的风险高于 FTU=12 的参与者（风险比：3.2，95%置信区间：1.4-7.7），调整了可能的混杂因素。
后牙缺失与养老院老年居民发热的风险相关。
