Participants chose AC degree and DHC degree by their subjective perception. An orthodontist chose AC degree and DHC degree by their objective measurement.</p><p><b>RESULTS</b>71.08% and 70.59% of 204 participants respectively chose 'no need treatment' of AC degree and DHC degree by their subjective perception. 19.12% and 9.80% of participants were respectively chosen 'no need treatment' of AC degree and DHC degree by orthodontist's objective measurement. Objective measurement degree of orthodontist was higher than subjective perception degree of participants. Subjective perception of participants was little related to objective measurement of orthodontists. AC degree of male participants' subjective perception was lower than the female. DHC degree of urban participants' subjective perception was higher than the rural. DHC and AC degree of only child participants' subjective perception was higher than non-only child.</p><p><b>CONCLUSION</b>Perception about malocclusion, dental health and aesthetic had significant difference between 16 to 22-year-old young adults and orthodontists.
