Abstract
|
|
|
The purpose of this study is to investigate the age-and sex-related changes in the pH of resting saliva, viscosity, microorganisms and immunoglobulin A of stimulated whole saliva, and to investigate their correlation.
The 120 healthy subjects were included in this study and the author used cone-and-plate digital viscometer for viscosity, MSB agar tor Streptococcus mutans, SL Rogosal agar for lactobacilli, and single radial immunodiffasion technique for
immunoglobulin
A.
@ES The obtained results were as follows:
@EN 1. There was no significant difference in pH, viscosity, Streptococcus mutans lactobacilli and immunoglobulin A of the saliva between males and females.
2. The viscosity values of stimulated whole saliva showed the increasing pattern with aging.
3. DMFS(or dmfs) rate was not correlated with pH, viscosity, Streptococcus mutans, lactobacilli and immunoglobulin A of the saliva.
4. There was a significant difference in the concentration of immunoglobulin A between the group under 10 and groups above 10.
5. The viscosity yalues of stimulated whole saliva showed the increasing patt(??)n with decreasing of the number of Streptococcus mutans.
