Correlation of profile esthetic indexes and esthetics evaluation in young females / 中华医学美学美容杂志

ABSTRACT

Objective To find the facial soft tissue measured indexes related to esthetic evaluation.Methods Thirty women were selected and scanned with CBCT;all individuals showed normal jaw,and lateral profile was taken in natural head posture.All the data measured including E line were imported with software Winceph 8.0 and overlapped,acquiring lateral cephalometric radiographs in natural head posture.29 orthodontists and 85 laypersons were invited to evaluate the attractiveness of this 30 profile silhouettes.18 esthetic indexes including E line were measured by Winceph 8.0.Paired t-tests were carried out for measured values of aesthetic indexes from two groups.Then Pearson correlation analysis was used to each silhouette score and values of aesthetic indexes were analyzed.Results Orthodontists group had average 0.05 points higher than laypersons.The aesthetic evaluation was different between orthodontists and laypersons with statistical significance.The measured indexes were correlated with measured values of two groups,including TLL-TVL,B'-TVL,Pos'-TVL (P＜0.05).Conclusions There are differences between orthodontists and laypersons in soft-tissue profile esthetic evaluation.The value of TLL-TVL,B'-TVL and Pos TVL are three key soft-tissue measurements that influence the esthetic indexes both for orthodontists and laypersons.The head position is an element that influences esthetic evaluation.
