Perception of adults' smile esthetics among orthodontists, clinicians and laypeople

Abstract

OBJECTIVE: Smile esthetics has become a major concern among patients and orthodontists. Therefore, the aim of this study was: (1) To highlight differences in perception of smile esthetics by clinicians, orthodontists and laypeople; (2) To assess factors such as lip thickness, smile height, color gradation, tooth size and crowding, and which are associated with smile unpleasantness. METHODS: To this end, edited photographs emphasizing the lower third of the face of 41 subjects were assessed by three groups (orthodontists, laypeople and clinicians) who graded the smiles from 1 to 9, highlighting the markers that evince smile unpleasantness. Kruskall-Wallis test supplemented by Bonferroni test was used to assess differences among groups. Additionally, the prevailing factors in smile unpleasantness were also described. RESULTS: There was no significant difference (P = 0.67) among groups rates. However, the groups highlighted different characteristics associated with smile unpleasantness. Orthodontists emphasized little gingival display, whereas laypeople emphasized disproportionate teeth and clinicians emphasized yellow teeth. CONCLUSION: Orthodontists, laypeople and clinicians similarly assess smile esthetics; however, noticing different characteristics. Thus, the orthodontist must be careful not to impose his own perception of smile esthetics.

Esthetic perception of smile components by orthodontists, general dentists, dental students, artists, and laypersons

“…In the present study, the golden ratio was evaluated only in the lateral incisors, and the changes were perceived by orthodontists, general dentists, and laypersons with an acceptable threshold of 3 mm. In a study by Cotrim et al ,. laypeople put more emphasis on disproportionate teeth.…”

Perception of Smile Esthetics by Orthodontists, Non-Dental and Dental Students: A Comparative Study

“…However, dentists did not rate excess gingival display as unattractive, even with a maximum of 4.0 mm. 6 In a study conducted by Cotrim ER et al, 8 the groups (orthodontists, clinicians and laypersons) emphasized upon different features contributing to smile unpleasantness. Orthodontists stressed on little gingival display, whereas laypersons highlighted disproportionate teeth.…”
