Oral healthcare professionals are at increased risk of infection by SARS-CoV-2. The aim of this study was to evaluate the prevalence of COVID-19 in a population of workers who provided services during the COVID-19 pandemic at a dental care and educational institution in the Buenos Aires Metropolitan Area.
This was a descriptive, cross-sectional study including 358 workers who provided essential services during the first 180 days of the COVID-19 pandemic at the Dental Hospital at Buenos Aires University School of Dentistry (FOUBA). Following epidemiological data, these workers underwent diagnostic testing for COVID-19 (1- nasal or throat swab tests; 2- blood test for enzyme-linked immunosorbent assays [ELISA]; 3- commercial rapid serology test).
Three diagnostic tests were implemented. Rapid tests were performed on 290 subjects, with 255 negative results (88%; CI95: 84%-91%) and 35 positive (12%; CI95: 9%-16%); ELISA on 317 subjects, with 308 negative (97%; CI95: 95%-98%) and 9 positive (3%; CI95: 2%-5%); and PCR on 204 subjects, with 196 negative (96%; CI95: 92%-98%) and 8 positive (4%; CI95: 2%-8%). There were 358 subjects who were evaluated by ELISA or PCR, with 342 negative results (96%; CI95: 93%-97%) and 16 positives (4%; CI95: 3%-7%).
For this sample of dentists, dental assistants and nonclinical personnel, the weighted prevalence of COVID-19 was 4%. Similar studies should be conducted at other dental care facilities in order to evaluate the worldwide impact of COVID-19 on the dental care community.
口腔保健专业人员感染新型冠状病毒2（SARS-CoV-2）的风险增加。本研究的目的是评估在布宜诺斯艾利斯大都市区一家牙科护理和教育机构中，在新冠疫情期间提供服务的工作人员群体中新冠病毒病（COVID-19）的流行情况。
这是一项描述性横断面研究，纳入了358名在布宜诺斯艾利斯大学牙科学院牙科医院（FOUBA）新冠疫情前180天期间提供基本服务的工作人员。根据流行病学数据，这些工作人员接受了新冠病毒病的诊断检测（1-鼻拭子或咽拭子检测；2-酶联免疫吸附测定[ELISA]血液检测；3-商业快速血清学检测）。
实施了三项诊断检测。对290名受试者进行了快速检测，其中255例结果为阴性（88%；95%置信区间：84%-91%），35例为阳性（12%；95%置信区间：9%-16%）；对317名受试者进行了ELISA检测，其中308例为阴性（97%；95%置信区间：95%-98%），9例为阳性（3%；95%置信区间：2%-5%）；对204名受试者进行了聚合酶链反应（PCR）检测，其中196例为阴性（96%；95%置信区间：92%-98%），8例为阳性（4%；95%置信区间：2%-8%）。有358名受试者接受了ELISA或PCR检测，其中342例结果为阴性（96%；95%置信区间：93%-97%），16例为阳性（4%；95%置信区间：3%-7%）。
对于该样本中的牙医、牙科助理和非临床人员，新冠病毒病的加权患病率为4%。应在其他牙科护理机构开展类似研究，以评估新冠病毒病对牙科护理社区的全球影响。
