The aim of this study was to investigate the relationship of fungiform papillae density with taste detection thresholds for sucrose of young male adults. One hundred and eighty two subjects aged 18-23 years (mean age: 21.9 +/- 1.2 years) were included. The densities of fungiform papillae were recorded with the aid of the digital camera, and the taste detection thresholds for sucrose were detected using a modified forced-choice triangle test. The mean density of papillae within all 170 statistic participants was 92.43 +/- 2.64/cm(2), for the 6-mm-diameter stained section of the tongue tip. The average detection threshold was 10.83 +/- 0.24 mmol/l, and the highest and lowest detection thresholds were 19.88 +/- 1.31 and 5.85 +/- 0.43 mmol/l, respectively. Also, an inverse correlation between the fungiform papillae density and the detection threshold was observed.
本研究的目的是调查年轻男性成年人的菌状乳头密度与蔗糖味觉检测阈值之间的关系。纳入了182名年龄在18 - 23岁（平均年龄：21.9±1.2岁）的受试者。借助数码相机记录菌状乳头的密度，并使用改良的强制选择三角试验检测蔗糖的味觉检测阈值。在所有170名有统计学意义的参与者中，舌尖6毫米直径染色区域内乳头的平均密度为92.43±2.64个/平方厘米。平均检测阈值为10.83±0.24毫摩尔/升，最高和最低检测阈值分别为19.88±1.31毫摩尔/升和5.85±0.43毫摩尔/升。此外，还观察到菌状乳头密度与检测阈值之间呈负相关。
