Abstract:

Objective To investigate the lip index and mouth breadth of the native Tibetan nationality female. Methods A total of 542 Tibetan nationality people aged 18-23 years old in Lhasa were selected to measure the mouth breadth,lip height and lip index. Results The mean of the Tibetan nationality female’s lip height was(18.01±4.29)mm, mouth breadth was(49.40±5.55)mm, and lip index was (36.60±8.21)mm. The mean values of lip height and lip index of the Kham Tibetan were significantly different from those of the Lhasa Tibetan and the Amdo Tibetan (P<0.01). There was significant difference in the mean mouth breadth between Lhasa Tibetan and the Amdo Tibetan (P<0.01).There was a significant negative correlation between lip height and age(r=-0.124,P<0.01),there was a significant negative correlation between lip index and age(r=-0.155,P<0.01),There was no statistically significant correlation between the width of the mouth and the age(P>0.05). Conclusion Kham Tibetan has a higher lip height, and the Amdo Tibetan has a wider mouth breadth. Tibetan nationality female lip index indicates the normal lips group as the main (69.2%), and wide group with mouth breadth as the main (73.6%).
