title: Bitter taste thresholds, numbers and diameters of circumvallate papillae and their relation with age in a Turkish population.
abstract: OBJECTIVE
  This study analyses the relationship between the sense of bitter taste and age. The relationships between these and the numbers and diameters of Circumvallate Papillae (CP) are also analysed.
  
  
  METHODS
  Twenty-four elderly subjects (from 65 to 85 years) and 30 young subjects (from 17 to 25 years) were studied.
  
  
  METHODS
  Bitter taste thresholds were determined by the three drop method with an ascending series of concentrations. The numbers and diameters of CP were observed by direct naked eye observation using a wooden tongue depressor, a gauge and a light source.
  
  
  RESULTS
  The bitter taste acuity was significantly poorer in the older sample. There was no relationship between the bitter taste acuity and number of papillae but an inverse relationship was observed between the bitter taste acuity and diameters of papillae, thus lower acuity was associated with larger papillae. It was also observed that the diameters of papillae were inversely related to the numbers of CP. The distribution of numbers and diameters of CP were not significantly different between these samples with age.
