We read with great interest the recent article by Khadijah A. Turkistani published online in May 2020 (Turkistani KA. Precautions and recommendations for orthodontic settings during the COVID-19 outbreak: a review. Am J Orthod Dentofacial Orthop 2020;158:175-81). The author aimed to help increase awareness and control cross-contamination among orthodontists, assistants, office staff, and patients during the coronavirus disease 2019 crisis.Although this article provides valuable information about preventive measures, we have a few questions. It would be better if the following measures could be considered.Both masks and N95 respirators are used for the protection against airborne infections such as severe acute respiratory syndrome coronavirus and influenza virus. Therefore, each patient needs to wear a disposable medical surgical mask when coming to the clinic. Patients in the incubation period are still infectious, so all patients visiting need to register their address and phone number for later follow-up. It is necessary to set a 1-m interval line at the entrance of the outpatient hall.The author stated, “If the patient is a suspected asymptomatic (no symptoms and no fever), then reschedule the appointment and advise the patient to self-quarantine at home for 14 days.” We suspect that self-isolation makes little sense. The proper way should be to do a virus test immediately and send the person to a designated hospital for treatment if positive or to a designated hotel for isolation if negative, in case of false negative results.Ultraviolet disinfection procedures will inactivate the new severe acute respiratory syndrome coronavirus 2. Ultraviolet is a good way to disinfect the air. It is also necessary to disinfect the ground, tabletop, and air after the daily diagnosis and treatment.The aforementioned measures can improve the safety of oral diagnosis and treatment.
