- lithium-containing mouthwash （Phase I ）
- description
- Phase I consists of 5 cohorts of 3-6 patients each, with all patients enrolled sequentially. Patients receive 0.03, 0.06, 0.10, 0.15, and 0.30 mol/L of lithium-containing mouthwash, respectively. In this phase, patients are instructed to use 10 mL of lithium mouthwash to gargle and retain it in the mouth for 5 minutes before spitting it out, from the first day of radiotherapy until the end of treatment.

- EXPERIMENTAL
- label
- lithium-containing mouthwash （Phase II ）
- description
- Phase II is a randomized, placebo-controlled trial. All patients are randomly assigned to the experimental group or the placebo group. The lithium concentration in the mouthwash used in the experimental group is the effective concentration identified in Phase I, whereas the placebo group receives a mouthwash formulation without lithium salts. From the first day of radiotherapy until the end of treatment, patients use 10 mL of lithium mouthwash or placebo mouthwash to gargle and retain it in the mouth for 5 minutes before spitting it out.
