The purpose of this study was to investigate the preference of Vertical Lip-Chin Ratio (= Sn-Stm /Stm-Me¡¯ hereafter VLCR) in Koreans.
The assessors consisted of 44 dentists (male 22, female 22) and 430 lay persons (male 303, female 127). The survey was performed using a questionnaire asking the order of preference. The profiles presented in the questionnaire were based on the profiles of two males and two females, each morphed according to the VLCRs of 1/1.8, 1/1.9, 1/2.0, 1/2.1, 1/2.2.
The results were as follows:
The difference between males and females, and the difference between dentists and lay persons in the preference of VLCR were not statistically apparent.
The most preferred VLCR was 1/1.9, and the least preferred VLCR was 1/2.2. These results indicate that the preferred VLCR is smaller than the previously reported VLCR ratios based, on the cephalometric evaluation of samples with favorable facial esthetics.
