The aim of this study was to investigate whether young adults with varying dental esthetics and histories of orthodontic treatment also differ in oral-health attitudes, preventive behaviors, and self-perceived oral health. The sample comprised 298 young adults, 18 to 30 years old, with at least 13 years of primary and secondary school education. The subjects were asked to complete questionnaires dealing with various measures related to oral-health attitudes, preventive behaviors, and perceptions of oral health. Dental esthetics were assessed by means of the aesthetic component of the index of orthodontic treatment need. Dental plaque accumulation was assessed in a subsample of respondents. Subjects with high dental-esthetics scores reported more favorable oral-health attitudes, such as internal control, dental awareness, value of occlusion, and preventive behavior expectations than subjects with lower scores. Subjects with previous orthodontic treatment showed greater internal control and dental awareness than those who had not previously been treated. Subjects ranking high in dental esthetics and those with previous orthodontic treatment reported stricter oral-hygiene adherence than others. Self-perceived oral health was better in high scorers on dental esthetics. Less plaque accumulation was found in subjects with higher dental esthetic scores and in those with previous orthodontic treatment. These findings suggest that favorable dental esthetics and previous orthodontic treatment might be important variables in explaining individual differences in oral-health attitudes and behaviors.
