The world is currently changing due to COVID-19, and the field of dentistry is no stranger to this. The care of patients in the dental office involves very strict biosafety protocols, and patients must be aware of the protection barriers implemented to allow satisfactory, safe dental care. The purpose of this study was to synthesize and analyze the management of the current biosafety standards for dental patients since the arrival of the COVID-19 pandemic. A bibliographic search of the main sources of information including MEDLINE (via PubMed), Scopus, Science Direct, SCIELO and Google Scholar was carried out. Articles published without language restriction, systematic reviews, literature reviews and observational studies were included. We identified the biosafety measures which must be taken before, during and after dental practice following the arrival of COVID-19, The main measures include telephone triage, temperature taking on arrival at the office, the organization of the waiting room, washing hands before entering the office, knowing the auxiliary radiographic exams of choice and what type of treatment can be performed, albeit with restrictions. In conclusion, dental patients must comply with all the biosafety measures established by international protection standards and implemented by dentists before, during and after dental practice, in order to reduce the possibility of COVID-19 infection.

The purpose of this research was to determine biosecurity measures at the dental office after the appearance of 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 conclusions 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.

The purpose of this investigation was to identify, synthesize and compare all the current information on the efficacy of dental masks, emphasizing their use, types and filters to prevent the spread and infection of COVID-19 and other infectious diseases. A bibliographic search of the main scientific databases was carried out using the words “masks, COVID-19 and dentistry”. Articles without language restriction up to May 31, 2020 were obtained. The types of masks, their half-life, method to use, sterilization, and proposed alternatives for dental masks were analyzed. Most of the articles refer to the use of N95 or FFP2 respirators presented as a strategy to extend the life of the masks and limited reuse. Regarding sterilization, most of the articles presented studies using ultraviolet germicidal irradiation (UVGI) as the sterilization method. Regarding respirator mask half-life, we recommend prolonged use, combined with a disposable surgical mask over the respirator mask. Finally, the use of N95 or FFP2 respirators are recommended as part of personal protective equipment for dental use.
