Biosafety Measures at the Dental Office after the Appearance of COVID-19: A Systematic Review

The purpose of this research was to determine biosecurity measures at the dental office after the appearance of coronavirus disease 2019 (COVID-19). A search was conducted in the main databases of the scientific literature using the words COVID-19, coronavirus, SARS-Cov2, biosecurity, disinfection and dentistry. We analyzed biosecurity and disinfection standards at the dental office and dental health personnel to date, and their adaptation to the needs and way of working of each. As a result, according to the information collected the following procedure was identified: A telephone appointment must be made and a questionnaire should be given before dental care; at arrival to the appointment, the temperature of the patient should be taken and proper cleaning and disinfection of the waiting room should be maintained. Panoramic radiography and CBCT are the auxiliary methods of choice. Absolute isolation and atraumatic restorative therapy techniques are a good alternative to decrease fluid exposure. The removal of protective clothing and accessories must follow a specific order and washing hands before and after is essential. In conclusion, the efficient biosecurity for dentists and patients in all dental care processes before, during, and immediately after the appointment reduces the risk of COVID-19 infection and allows healthy dental care environments.
