“Materials and methods:” The data were collected from 60 Indian subcontinents (35 males and 25 females) aged 22 to 35 years and 96 Japanese (53 females and 43 males) aged 18 to 24 years old. All subjects had not undergone any orthodontic treatment. They filled out a questionnaire, which had 5-degree criteria of satisfaction, (1: satisfied, 2: somewhat satisfied, 3: neither satisfied nor dissatisfied, 4: somewhat dissatisfied, and 5: dissatisfied) about the awareness of their own facial appearance describing the visual impression of 24 items. Nine of the questions were about the overall impression such as the impression of the face and the outline of the face, and fifteen were about facial parts such as eyelids, nose, lips, teeth and so on.
“Results:” (1) The mean awareness score for the subjects of Indian subcontinents ranged from 1.0 to 1.6 in female and from 1.4 to 2.2 in male for the overall impressions, and from 1.0 to 1.7 in female and from 1.5 to 2.4 in male for the facial parts. (2) Similarly the mean awareness score for Japanese subjects varied from 2.9 to 3.7 in female and from 3.0 to 3.3 in male for the overall impressions, and from 2.5 to 3.4 in female and from 2.6 to 3.3 in male for the facial parts. (3) Satisfaction score for the all 24 items differed significantly between the communities of Indian subcontinents and Japanese female and male. The evaluations were made using Mann-Whitney U-test.
“Conclusion:” In conclusion, the laypersons of Indian subcontinents revealed more satisfaction about their facial appearance (both overall impressions and facial parts) as compared to Japanese subjects.
