The study objective was to assess the knowledge of emergency dental treatments, the transmission routes of COVID-19 in the dental settings, necessary precautions to prevent disease transmission, and the associations between demographic factors and the mentioned domains among Iranian dental patients.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>This was a cross-sectional study conducted in October 2021. A systematic random sampling approach was used to select 244 participants who had sought services at the dental clinic of Tehran University of Medical Sciences before and during the pandemic. Data was collected using a combination of interviewer-administered and self-administered questionnaire. Three backward stepwise multiple logistic regression analyses were conducted to determine the associations between background factors (age, sex, education level, living status, history of dental visits, history of COVID-19 vaccination, and past COVID-19 infection) and knowledge about emergency dental treatments, knowledge about COVID-19 transmission routes, and knowledge about necessary preparations in dental settings.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>The mean (SD) scores for knowledge of emergency dental treatments, COVID-19 transmission routes, and essential preparations in dental settings measured on a 100-point scale were 77 (15.4), 84.2 (12.3), and 93.3 (12.1), respectively. Good knowledge of emergency dental treatments was associated with being under 55 years old (p = 0.03). Good knowledge of COVID-19 transmission routes was associated with living with individuals at a high risk of COVID-19 (p = 0.014) and having received the COVID-19 vaccine (p = 0.013). After adjusting for age, among participants aged 30 years and older, good knowledge of necessary preparations in dental settings was associated with being female (p = 0.012) and having received the COVID-19 vaccine (p = 0.001).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Patients who sought care at the dental clinic of Tehran University of Medical Sciences had good knowledge about the transmission routes of COVID-19 and the required preparations in dental settings, and limited knowledge about dental emergency treatments.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0301460","type":"journal-article","created":{"date-parts":[[2024,4,18]],"date-time":"2024-04-18T17:55:41Z","timestamp":1713462941000},"page":"e0301460","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":1,"title":["Patients\u2019 knowledge about dental emergencies, COVID-19 transmission, and required preparations in dental settings"],"prefix":"10.1371","volume":"19","author":[{"given":"Mohammad Reza","family":"Khami","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7570-8706","authenticated-orcid":true,"given":"Mahsa","family":"Karimi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Morenike Oluwatoyin","family":"Folayan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmad Reza","family":"Shamshiri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heikki","family":"Murtomaa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2024,4,18]]},"reference":[{"key":"pone.0301460.ref001","doi-asserted-by":"crossref","first-page":"623","DOI":"10.1007\/978-3-030-63761-3_34","article-title":"Impact of COVID-19 on Dentistry","volume":"1318","author":"A Tonkaboni","year":"2021","journal-title":"Adv Exp Med Biol"},{"issue":"16","key":"pone.0301460.ref002","doi-asserted-by":"crossref","first-page":"1610","DOI":"10.1001\/jama.2020.3227","article-title":"Air, Surface Environmental, and Personal Protective Equipment Contamination by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) From a Symptomatic Patient.","volume":"323","author":"SWX Ong","year":"2020","journal-title":"Jama"},{"issue":"1","key":"pone.0301460.ref003","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1038\/s41368-020-0075-9","article-title":"Transmission routes of 2019-nCoV and controls in dental practice.","volume":"12","author":"X Peng","year":"2020","journal-title":"Int J Oral Sci"},{"issue":"2","key":"pone.0301460.ref004","doi-asserted-by":"crossref","first-page":"53","DOI":"10.3390\/dj8020053","article-title":"Novel Coronavirus (COVID-19) and Dentistry-A Comprehensive Review of Literature.","volume":"8","author":"P Barabari","year":"2020","journal-title":"Dent J (Basel)."},{"issue":"1","key":"pone.0301460.ref005","doi-asserted-by":"crossref","first-page":"162","DOI":"10.1186\/s12903-021-01533-z","article-title":"Impact of COVID-19 on the oral health of adults in Wuhan and China: results of a nationwide online cross-sectional questionnaire survey.","volume":"21","author":"S Zhang","year":"2021","journal-title":"BMC Oral Health."},{"key":"pone.0301460.ref006","doi-asserted-by":"crossref","first-page":"555613","DOI":"10.3389\/fpsyg.2021.555613","article-title":"Differential Psychological Factors Associated With Unnecessary Dental Avoidance and Attendance Behavior During the Early COVID-19 Epidemic.","volume":"12","author":"YF Wen","year":"2021","journal-title":"Front Psychol."},{"issue":"1","key":"pone.0301460.ref007","doi-asserted-by":"crossref","first-page":"658","DOI":"10.1186\/s12903-023-03378-0","article-title":"The impact of periodontal disease on the clinical outcomes of COVID-19: A systematic review and meta-analysis.","volume":"23","author":"SA Al-Maweri","year":"2023","journal-title":"BMC Oral Health"},{"issue":"4","key":"pone.0301460.ref008","doi-asserted-by":"crossref","first-page":"e0249853","DOI":"10.1371\/journal.pone.0249853","article-title":"Knowledge, attitude, perception, and preventative practices towards COVID-19 in sub-Saharan Africa: A scoping review.","volume":"16","author":"UI Nwagbara","year":"2021","journal-title":"PLoS One"},{"issue":"1","key":"pone.0301460.ref009","doi-asserted-by":"crossref","first-page":"e0245176","DOI":"10.1371\/journal.pone.0245176","article-title":"Knowledge, attitude and practice survey of COVID-19 pandemic in Northern Nigeria.","volume":"16","author":"MA Habib","year":"2021","journal-title":"PLoS One"},{"key":"pone.0301460.ref010","unstructured":"Population Mean\u2013Sample Size.
