  Abstract

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/cm2, 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.

Key words: fungiform papillae density, sweet detection threshold, young males
