A critical appraisal of evidence in the use of preprocedural mouthwash to avoid SARS-CoV-2 transmission during oral interventions.

OBJECTIVE: The study aimed to review and report the current evidence supporting the use of mouthwashes as a preprocedural protocol on dental offices. MATERIALS AND METHODS: This study is a secondary one that performed a comprehensive literature search of scientific studies published up to 10th August 2020 in PubMed, Scopus, Web of Science, and Scientific Electronic Library Online (Scielo) databases. The electronic search strategy was performed using free text and DeCS/MeSH terms. RESULTS: Only five studies were included in this work, despite 140 studies that were identified with the research strategy. In vivo studies were carried out in two works, in vitro studies were described in two papers, and a in silico approach was used in one work. No cetylpyridinium chloride studies were identified, while chlorhexidine and povidone studies were more studied. CONCLUSIONS: There is reduced evidence about how preprocedural mouthwashes decrease SARS-CoV-2 salivary load.

Knowledge regarding emergency management of avulsed teeth among elementary school teachers in Jaboatão dos Guararapes, Pernambuco, Brazil.

OBJECTIVE: The purpose of the present study was to assess the knowledge regarding emergency management of tooth avulsion among elementary schoolteachers in the city of Jaboatão dos Guararapes, Pernambuco, Brazil. MATERIALS AND METHODS: A total of 338 teachers answered a questionnaire with items on emergency procedures following tooth avulsion. RESULTS: The majority of teachers (89.1%) had received no previous orientation regarding management of dental trauma and 81.4% had not witnessed an accident in which tooth avulsion had occurred. If an avulsed tooth had fallen to the ground, 84.3% of the teachers said they would pick it up, and 67.8% of them stated that they would clean it with water or some other liquid. A total of 33.1% said that they would take the student with the tooth in hand to a dental office. Of the respondents 88.5% would seek professional help immediately; 85.2% stated they would be unable to reimplant the avulsed tooth; and 39.3% would store the tooth in water. CONCLUSIONS: A lack of technical information was observed among teachers regarding management of tooth avulsion. Educational campaigns at schools are necessary to modify the behavior of the teachers with regard to management of tooth avulsion. Further studies should be carried out for the assessment of teachers who have participated in educational campaigns to make the treatment of dental trauma a matter of public interest.
