Taste and salivary function.

RESUMO
Human taste perception was remarkably unimpaired in eight individuals with severe, chronic failure of all major and minor salivary gland function. Subjective reports of taste experience and objective measures of suprathreshold sensitivity were within normal limits for the overwhelming majority of these individuals. Impairments of threshold sensitivity for at least one quality was common, but normal thresholds for all four qualities were observed in one individual. These data demonstrated that the functional integrity of the taste system is not dependent upon the presence of normal saliva in the mouth. Thus, the suggestion that a salivary factor is responsible for the maintenance of taste receptor end organs can be rejected and attention directed toward other mechanisms, not dependent on saliva, that might account for the unusual resistance of these cells to environmental insult.
