Methods The circuits of instantly different metallic contact were simulated in artificialsaliva, and electrical potential of every couple and 15 currents of instant contact were measured.
Conclusions: Artificialsaliva and Chinese traditional medicine are effective for radiation xerostomia, and they can improve the quality of life for patients with salivary gland dysfunction.
