The aim of the study was to evaluate the relationship between nasolabial angle (NLA) with maxillary incisor proclination (U1-NA) and upper lip thickness (ULT).
Pretreatment lateral cephalometric radiographs of 120 patients were taken, and NLA, U1-NA, and basic ULT measurements were obtained for each patient. Descriptive statistics were calculated for all the variables involved in the study. The correlation was found using the Pearson correlation coefficient (r) test. < 0.01 was considered statistically significant.
The mean values of NLA, upper incisor proclination, and ULT were found to be 91.38° ± 7.10°, 34.21° + 5.17°, and 15.38 ± 1.76 mm, respectively. r (r = -0.583) was found between NLA and upper incisor proclination and (r = -0.040) for NLA and ULT.
There is a statistically significant relationship between NLA and U1-NA.

本研究旨在评估鼻唇角（NLA）与上颌切牙倾斜度（U1-NA）及上唇厚度（ULT）之间的关系。
对120例患者进行治疗前的头颅侧位X线片拍摄，并测量每位患者的NLA、U1-NA及基础ULT。对研究中涉及的所有变量进行描述性统计分析。采用Pearson相关系数（r）检验来确定相关性。P<0.01被认为具有统计学意义。
NLA、上颌切牙倾斜度及ULT的平均值分别为91.38°±7.10°、34.21°±5.17°和15.38±1.76mm。NLA与上颌切牙倾斜度之间的r值为（r = -0.583），NLA与ULT之间的r值为（r = -0.040）。
NLA与U1-NA之间存在统计学上的显著关系。
