Abstract
This paper described physiochemical characteristics of the pH curve of saliva that accompanied escape of CO 2 and that was recorded by a previously reported method. Monthly sample of the resting saliva was collected by a small paper slip from five adults (59.9±16.5 years old) over 36 months. The pH curves were examined to represent differences in secretion characteristics among individuals. The following results were obtained: (1) Three variables, pH 1, Δ pH I, and Δ pH L, that represent a saliva pH curve indicated secretory characteristics of each individual since the intra-individual variance of them was significantly smaller than the inter-individual variance. (2) These values (mean±S.D.) obtained from five adults were 7.03±0.54, 0.24±0.21, and −0.10±0.12, and those obtained from 663 young adults (21.7±2.4 years old) were 7.14±0.44, 0.26±0.23, and −0.08±0.13. (3) A characteristic about amplitude of the Δ pH I of each individual was maintained over 36 months under the healthy condition. Seasonal variation of the three pH variables and their statistical distribution were also investigated.
