Abstract

Purpose: This study aimed to clarify the impact of the coronavirus disease 2019 (COVID-19) pandemic on individual dental-visit behaviour and examine the difference between elderly and other individuals regarding the impact on dental visits.

Materials and methods: An interrupted time-series analysis was performed to examine the change in data from the national database before and after the first declaration of a state of emergency.

Results: The number of patients visiting a dental clinic (NPVDC), number of dental treatment days (NDTD) and dental expenses (DE) during the first declaration of a state of emergency decreased by 22.1%, 17.9%, and 12.5% in the group under 64 years of age and 26.1%, 26.3%, and 20.1% in the group over 65 years of age, respectively, compared with those in the same month of the previous year. Between March and June 2020, the monthly NPVDC and NDTD were significantly reduced (p < 0.001, p = 0.013) in those over 65 years of age. The DE did not change statistically significantly in either the under 64 group or the over 65 group. There was no statistically significant change in the slope of the regression line in the NPVDC, NDTD, and DE before and after the first state-of-emergency declaration.

Conclusion: The first state of emergency greatly reduced the NPVDC, NDTD, and DE compared to those in the previous year. In people aged over 65 years, it might still be unresolved 2 years after the postponement of dental treatment owing to the first declaration of a state of emergency.

2019 年冠状病毒疾病大流行对日本牙科就诊人数的影响》。

目的：本研究旨在阐明2019年冠状病毒病（COVID-19）大流行对个人牙科就诊行为的影响，并研究老年人和其他人群在牙科就诊影响方面的差异：对国家数据库中的数据在首次宣布紧急状态前后的变化进行了间断时间序列分析：与上一年同期相比，首次宣布进入紧急状态期间的牙科诊所就诊人数（NPVDC）、牙科治疗天数（NDTD）和牙科费用（DE）分别下降了22.1%、17.9%和12.5%，64岁以下人群和65岁以上人群分别下降了26.1%、26.3%和20.1%。在 2020 年 3 月至 6 月期间，65 岁以上人群的每月 NPVDC 和 NDTD 显著降低（p < 0.001，p = 0.013）。64 岁以下组别和 65 岁以上组别中的 DE 均无明显统计学变化。在首次宣布进入紧急状态前后，NPVDC、NDTD 和 DE 的回归线斜率在统计学上没有明显变化：结论：与前一年相比，第一次紧急状态大大降低了NPVDC、NDTD和DE。对于 65 岁以上的老年人来说，由于首次宣布紧急状态而推迟牙科治疗 2 年后，问题可能仍未得到解决。
