Fixed orthodontic treatment requires the ability to maintain dental and oral hygiene which is more difficult and takes a long time, continuously, and some orthodontic procedures produce droplets and aerosols, so many orthodontic patients have to postpone their treatment schedule to minimize the risk of spreading COVID-19. The purpose of this study was to find out how dental care was carried out by students using fixed orthodontics at Mulawarman University during the COVID-19 pandemic. This research is a descriptive observational research type and the sample was selected by simple random sampling technique. The sample consisted of 96 respondents from 13 faculties at Mulawarman University. The data obtained are primary data from the questionnaire. The results showed that more respondents brushed their teeth twice a day (59.38%), consumed sugar (48.96%), visited the dentist (44.79%) and were willing to attend dentist appointments during the COVID-19 pandemic. (50%), used a soft toothbrush (38.54%), and did not use dental hygiene aids (56.25%). It is hoped that the results of this study can be useful for further research related to oral hygiene for fixed orthodontic users so that proper oral hygiene maintenance during orthodontic treatment can be carried out.
