ABSTRACT
Objective To compare the different ways of alkaline mouthwash slobber use in preventing the oral infection in patients with fever. Methods The patients who satisfied the requirements were involved and randomly divided into A, B and C group. A group did not use alkaline mouthwash; B group prescribed alkaline mouthwash slobber following the doctor's advice; C group received propaganda and demonstration of intensive use of the alkaline mouthwash, and then used the slobber in right way under the surveillance of nurses. The infection rates of oral ulcer and oral leukoplakia were compared and analyzed among the three groups. Results The incidence rates of oral ulcer and oral leukoplakia gradually decreased among the three groups and the differences had statistical significance (χ2=9.243,P=0.010;χ2=6.495,P=0.033).Compared with A group, there was no significant differences in the rates of oral ulcers and oral leukoplakia between Group A and B(OR=0.486, 95%CI:0.113-2.087;OR=0.557, 95%CI: 0.120-2.583), but the incidence rates of oral ulcers and oral leukoplakia gradually decreased(OR=0.024, 95%CI:0.002-0.293;OR=0.036, 95%CI:0.003-0.448)in C group. Conclusions Strengthening use of alkaline mouthwash slobber is more effective in preventing oral infection in patients with fever compared with the routine way of mouthwash use.
