A retrospective study was performed to verify if the number of admissions for urgent dental care in the Urgent Dental Care Service of San Paolo Hospital in Milan (Italy) was directly related to the different phases of the COVID-19 pandemic. Different periods were analyzed: 25 March-5 April 2019 (pre-COVID); 23 March-3 April 2020 (lockdown); 8 June-19 June 2020 (reopening); and November 9-November 20 (second wave). Raw data regarding admissions, diagnoses, and treatments were extracted. Descriptive and bivariate analyses were performed. The survey included 901 admissions, 285 in pre-COVID, 93 during lockdown, 353 in reopening, and 170 in the second wave. In each time period, statistically significant differences were found in the prevalence of each kind of diagnoses (χ = 20.33 = 0.01 for endodontic emergencies, χ = 29.05 < 0.01 for cellulitis/phlegmon, χ = 28.55 < 0.01 for periodontal emergencies, Fisher's Exact Test < 0.01 for trauma, and χ = 59.94 0.01 for all other kinds of diagnosis). A remarkable increase in consultations (+186.36%) and other treatments (+90.63%) occurred during reopening. Tooth extraction was the most frequently delivered treatment, but suffered the largest reduction during lockdown (-79.82%). The COVID-19 pandemic has highly affected dental activity in north Italy, underling the weaknesses of a private dental system in a pandemic scenario.
一项回顾性研究旨在验证意大利米兰圣巴托洛梅奥医院（San Paolo Hospital）紧急牙科护理服务（Urgent Dental Care Service）的紧急就诊人数是否与 COVID-19 大流行的不同阶段直接相关。分析了不同时期：2019 年 3 月 25 日至 4 月 5 日（大流行前）；2020 年 3 月 23 日至 4 月 3 日（封锁）；2020 年 6 月 8 日至 19 日（重新开放）；2020 年 11 月 9 日至 20 日（第二波）。提取了有关就诊、诊断和治疗的原始数据。进行了描述性和双变量分析。该调查包括 901 例就诊，大流行前为 285 例，封锁期间为 93 例，重新开放期间为 353 例，第二波期间为 170 例。在每个时期，各种诊断的患病率均存在统计学差异（χ = 20.33 = 0.01 用于牙髓急症，χ = 29.05 < 0.01 用于蜂窝织炎/痈，χ = 28.55 < 0.01 用于牙周急症，Fisher 精确检验 < 0.01 用于外伤，χ = 59.94 0.01 用于所有其他诊断类型）。重新开放期间咨询量（增加 186.36%）和其他治疗（增加 90.63%）显著增加。拔牙是最常实施的治疗方法，但在封锁期间降幅最大（-79.82%）。COVID-19 大流行极大地影响了意大利北部的牙科活动，凸显了大流行情况下私人牙科系统的弱点。
