BACKGROUND: 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.
METHODS: 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).
RESULTS: 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.
CONCLUSIONS: Posterior teeth occlusion correlated with the risk of fever in older residents of nursing homes.
