Abstract
This paper aimed to compare the characteristics (concentration, PH and mutans streptococcus) saliva in both status resting saliva and stimulated saliva in preschoolers of Kerman city. In this study, 100 children aged 5 years among patients admitted to the pediatric ward of Kerman dental school and dental offices, some experts in Kerman dental school participated. Resting and stimulated saliva (after chewing oral paraffin) children collected and in concentrations, PH and the amount of mutans streptococcus was measured. Mc Nemar test to compare the frequency of positive and negative cultures before and after stimulation as well as paired t-test to compare the saliva pH and concentration of not stimulated saliva and stimulated saliva in two modes was used. The significance level was set less than 0.05.The mean resting salivary osmolality of the population: 30.42 ± 87.41 and the average salivary osmolality of the total population were 79.81. Osmolality differences in saliva before and after stimulation with each other was significant (p = 0.009, paired t-test). The mean of resting saliva in the total population PH 0.45 ± 7.78 and the average PH stimulated saliva in the total population was 8.22 and the difference before and after each significant (p = 0.02, paired t-test). In mutans streptococcus in test samples in all 71 patients (71%) positive test and 29 patients (29%) had a negative test that number of positive cultures are equal before and after stimulation of saliva and thus the difference between the two groups (p> 0.05) was observed. In terms of comparing the properties of resting and stimulated saliva can conclude that salivary stimulated PH was significantly higher than resting saliva. While stimulated saliva osmolality was significantly less than resting saliva and the frequency of positive test mutans streptococcus in saliva before and after stimulation had no significant difference (p> 0.05). This means that test results on samples of mutans streptococcus in stimulated saliva and resting saliva is same.
