Different periods were analyzed: 25 March\u20135 April 2019 (pre-COVID); 23 March\u20133 April 2020 (lockdown); 8 June\u201319 June 2020 (reopening); and November 9\u2013November 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 (\u03c72(3) = 20.33 p = 0.01 for endodontic emergencies, \u03c72(3) = 29.05 p &lt; 0.01 for cellulitis\/phlegmon, \u03c72(3) = 28.55 p &lt; 0.01 for periodontal emergencies, Fisher\u2019s Exact Test p &lt; 0.01 for trauma, and \u03c72(3) = 59.94 p &lt; 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 (\u221279.82%). The COVID-19 pandemic has highly affected dental activity in north Italy, underling the weaknesses of a private dental system in a pandemic scenario.<\/jats:p>","DOI":"10.3390\/ijerph18041812","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T22:41:25Z","timestamp":1613169685000},"page":"1812","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Influence of the COVID-19 Pandemic on Dental Emergency Admissions in an Urgent Dental Care Service in North Italy"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2704-0585","authenticated-orcid":false,"given":"Maria Grazia","family":"Cagetti","sequence":"first","affiliation":[{"name":"Department of Biomedical, Surgical and Dental Science, University of Milan, 20142 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7040-5084","authenticated-orcid":false,"given":"Araxi","family":"Balian","sequence":"additional","affiliation":[{"name":"Department of Biomedical, Surgical and Dental Science, University of Milan, 20142 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicole","family":"Camoni","sequence":"additional","affiliation":[{"name":"Department of Biomedical, Surgical and Dental Science, University of Milan, 20142 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8573-485X","authenticated-orcid":false,"given":"Guglielmo","family":"Campus","sequence":"additional","affiliation":[{"name":"Department of Restorative, Preventive and Pediatric Dentistry, University of Bern, Freiburgstrasse 7, 3012 Bern, Switzerland"},{"name":"Department of Surgery, Microsurgery and Medicine Sciences, School of Dentistry, University of Sassari, Viale San Pietro 3\/c, 07100 Sassari, Italy"},{"name":"School of Dentistry, Sechenov University, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,12]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2021, January 13).
