Eligible patients who underwent microsurgical free flap reconstruction for oral cancer were enrolled once their postoperative condition stabilized. They were randomly assigned in a 1:1 ratio to the experimental group using a computer-generated randomization table. Immediately after allocation, the first saliva collection (T0) was performed. Participants in the experimental group received daily hydrogen water oral care, using hydrogen water with a concentration of 1.1 mg\u002FL and a dissolution stability of at least 12 hours.
