The subjects were evaluated on their clinical characteristics of xerostomia using visual analogue scale for xerostomia, dry mouth questionnaire, unstimulated salivary flow rate. In addition, Yin-deficiency questionnaire was used to evaluate the Yin-deficiency state and Winkel tongue coating index and Digital Tongue imagin system were used to measure the tongue coating of patients.

Also, thin coating pattern was showed in this elderly patients with xerostomia and this result was regarded to the influence of Yin-deficiency. The thin coating patten was observed in the group with higher Yin-deficiency score. There was no difference in tongue coating between the hyposalivation and normosalivation group.
