Among all subjects who participated in the survey in the 9th 1st year (2022), 2,448 men (44.0%) and 3,166 women (56.0%) aged 12 or older were identified to determine oral care behavior according to orthodontic treatment experience. The purpose was to provide basic data on the oral care of patients wearing orthodontic appliances. 1. When it comes to brushing teeth, brushing before going to bed was the highest. Regarding the use of oral care products, 3,965 people (69.1%) said they 'do not use dental floss', 4,064 people (73.2%) said they 'do not use interdental brushes', and 4,064 people (73.2%) said they used oral rinse. 'I don't do it' was the highest at 4,417 (77.7%), and electric toothbrushes were the highest at 'I don't do it' at 5,241 (93.6%). 2. In terms of the effect of orthodontic treatment experience on toothbrushing time, with orthodontic treatment experience, toothbrushing after breakfast was 0.598 times more likely (P<0.001), and toothbrushing after lunch was 1.482 times more likely (P<0.001). Toothbrushing after dinner was 0.805 times higher (P=0.049), and toothbrushing before going to bed was 1.794 times higher (P<0.001), which was statistically significant. 3. When having orthodontic treatment experience, dental floss was found to be used 1.434 times more often (P=0.002), interdental brushes were used 1.464 times more times (P<0.001), and oral rinses were found to be used 1.457 times more times (P=0.002), which was statistically significant.
