Introduction: Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus (SARS-CoV-2). It emerged as a global pandemic in early 2020, affecting more than 200 countries and territories. The infection is highly contagious, with disease transmission reported from asymptomatic carriers, including children. It spreads through person-to-person contact via aerosol and droplets. The practice of social distancing-maintaining a distance of 1-2 m or 6 ft-between people has been recommended widely to slow or halt the spread. In orthodontics, this distance is difficult to maintain, which places orthodontists at a high risk of acquiring and transmitting the infection. The objective of this review is to report to orthodontists on the emergence, epidemiology, risks, and precautions during the disease crisis. This review should help increase awareness, reinforce infection control, and prevent cross-transmission within the orthodontic facility. Methods: A comprehensive literature review of English and non-English articles was performed in March 2020 using COVID-19 Open Research Dataset (CORD-19 2020), PubMed, MEDLINE, Scopus, and Google Scholar to search for infection control and disease transmission in orthodontics. Results: This review emphasizes minimizing aerosol production and reinforcing strict infection control measures. Compliance with the highest level of personal protection and restriction of treatment to emergency cases is recommended during the outbreak. Surface disinfection, adequate ventilation, and decontamination of instruments and supplies following the guidelines are required. Conclusions: Reinforcing strict infection control measures and minimizing personal contact and aerosol production are keys to prevent contamination within orthodontic settings. Although no cases of COVID-19 cross-transmission within a dental facility have been reported, the risk exists, and the disease is still emerging. Further studies are required.

“…Also, blood agar environment detects only gram-positive bacteria and EMB culture environment detects both gram-negative and gram-positive bacteria. Furthermore, the cap of culture environments was closed and placed in an incubator with temperature 37 for 48 hours (Figure 1c) and based on the color change of bacteria in the culture environment, type of bacteria was recognized (Figure 1d) [30] . It should be mentioned that for attenuation, a McFarland standard A0.5 was followed [31] and colony counting was performed [32] .…”

“…In this study, a solid culture environment and plate dishes were used. For performing the culture, swabs were collected from each device and placed in tightly closed capped tubes and then placed in the autoclave with a temperature of 121 for sterilization [30] . After sterilization, the device name (Figure la) was written on every tube and was taken to the culture test place along with an amount of physiological serum which was poured into the test tube.…”

Hospitals are the focus of many infections which cause the intensification of the patients’ illness and even their death. The number of bacteria on various hospital equipment was counted before and after being disinfected with manual cleaning (MC), hydrogen peroxide vapour (HPV) and ultraviolet-C (UV-C). The effectiveness of disinfection of hospital beds in intensive care unit (ICU) using the three methods MC, HPV and UV-C has been 66.67%, 100% and 50%, respectively. Hence, the effectiveness of HPV method in the disinfection of this unit has been higher than others. The effectiveness of otoscope disinfection in the ICU and blood pressure meter in the operating room with three methods of MC, HPV and UV-C has been 0%, 50% and 100%, respectively. So, for disinfecting these small outfits, UV-C method has proven to be the best one. In case of programming, the correct move of portable UV-Cs for complete coverage of massive equipment, disinfection with UV-C method may be considered more effective than other methods.

“…However, toxic disinfectant residues remain a problem for its further application [5]. Physical sterilization creates and utilizes extreme environment to destroy the physical structure of the microorganisms, by means of ultraviolet irradiation, heating, ionizing radiation, and microwave sterilization [6], and are often used in daily life or medical equipment disinfections. Biological sterilization is eco-friendly.…”

Atmospheric pressure plasma jet (APPJ) is a promising technique for the sterilization of pathogenic microorganisms in an ambient environment. In this work, a helium-APPJ was generated by double dielectric barrier discharge and applied to the sterilization of model microorganism in air and water. Discharge characteristics (including waveform and frequency of applied voltage), jet properties (such as feed gas flow rate, jet length, thermal effect, and optic emission spectra), and sterilization performance (in terms of clear/sterilized area, size of plaques, and sterilization efficiency) were investigated. Homogeneous helium plasma jet was generated in an energy-efficient way (18 kHz, 6 kV, 0.08 W) with a 19 mm jet and limited heating. The He-APPJ achieved good sterilization performances within very short treatment time (as short as 30 s). For surface sterilization, the area of clear zone and size of the plaque were 1809 mm2 and 48 mm, respectively, within 5 min treatment. For water sterilization, 99.8% sterilization efficiency was achieved within 5 min treatment. The optic emission spectra suggest that active species such as excited molecules, ions, and radicals were produced in the He-APPJ. The as-produced active species played important roles in the sterilization process.
