The Relationship Between Smile Type, Dental Composition, and Personality Traits in Young Adults

Abstract

Introduction. This study investigates the complex interplay between dental compositions, smile styles, and personality traits in young adults seeking oral and dental care, guided by the Visagism paradigm. Methods. A total of 150 young adult volunteers aged 18-35 years participated in the study. The participants completed a questionnaire designed to assess personality traits. A survey containing various personality characteristics was administered to determine the participants’ fundamental personality traits, with respondents encouraged to indicate the traits they most closely identified with honestly. Based on the survey responses, individuals were categorized into one of four main personality groups: melancholic/sensitive, sanguine/dynamic, choleric/strong, and phlegmatic/peaceful. Subsequently, a careful clinical examination was conducted to assess each patient’s tooth form, smile style, and the visibility of teeth and gums at different smile stages (stages III and IV). Statistical analysis was then conducted. Results. Oval tooth forms (36%) and the commissure (Mona Lisa) smile style (72.5%) were most frequently observed, aligning with previous research. Notably, women exhibited a higher prevalence of a melancholic temperament. However, the study found no significant relationship between self-reported personality traits and dental compositions or smile styles. Conclusions. The study did not confirm a significant association between personality traits and smile styles or dental forms. While the findings align with existing research, they highlight the complexity of the Visagism paradigm, emphasizing the need for further investigations into the relationship between temperament and dental aesthetics.
