No effects of smoking or drinking habits on salivary amylase

Nonstimulated and expectorated whole saliva was collected from 166 males and 180 females. To investigate biological effects of smoking and drinking habits on digestive functions in healthy populations, salivary total proteins and amylase activity were determined in the saliva samples. Sex differences in the salivary components were not found. Neither of the two habits had any significant influences on salivary proteins or amylase activity in the subjects. Light to moderate uses of tobacco or alcohol may not influence basal components of saliva.
