title: [Quantitative studies of taste and fungiform papillae on the anterior human tongue].
abstract: OBJECTIVE
  To study qantitatively in the taste and fungiform papillae on the anterior human tongue.
  
  
  METHODS
  Sixty normal adults were evaluated the spatial taste and the fungiform papilla density at spatially-matched sides on the right and left sides of the anterior tongue. The taste stimulative solutions were delivered to a spatially-matched flow chamber attached to the surface of the right or left anterior tongue.
  
  
  RESULTS
  (1) There is no statistical difference in number of the fungiform papillae, taste threshold and magnitude matching between right/left, male/female and races; (2) There is a significant difference in fungiform papilla density and taste functions in different individuals; (3) The fungiform papilla density is the key to taste function on 2/3 anterior of tongue, and is positively correlated to it; (4) The use of a spatially-matched flow chamber is a valid test system for overall, objective and accurate evaluating taste on the 2/3 anterior of tongue, and can be used to study quantitatively the fungiform papilla density.
  
  
  CONCLUSIONS
  It is of clinical significance for the diagnosis of taste diseases and the dynamic studies of the taste and the fungiform papillae after lingual nerve injury and repair.
