Keywords:

The objectives of this study was to analyze the relationship of salivary pH, buffer capacity and total protein in saliva of dry mouth elderly patients. Method: The subjects of this study were elderly patient (> 65 years old) 120 person. Divide into 4 groups by salivary flow rate measurement and xerostomia questionnaires, 1. Xerostomia and hyposalivation group, 2. Xerostomia group, 3. Hyposalivation group and 4. Normal group. All group were test pH by pH meter, Buffer capacity by Ericson’s method and Protein test by Biuret assay. Results: The results show that female elderly were had high prevalence of hyposalivation (53.75 %) than male (42.5%) and xerostomia (52.5 %) than male (40%). Salivary pH in normal group was higher than another groups. Buffer capacity were not significant different in each groups. Concentration of total protein in saliva for normal group had significant higher than xerostomia and hyposalivation groups. Conclusion: Xerostomia and hyposalivation group had significant different in salivary pH and salivary total protein.
