The dental ulcer appear in the decreased immunity.the absolute value of neutrophil reach the lowest after 7-14 days for chemotherapeutic patients with further impairment of bone marrow hematopoietic function,and less eating and more microbial group generation leading to weak the self-clean function to cause stink and to hurt oral mucosa reaching to the dental ulcer.

The method of gargling and containing in mouth is easily accepted by patients,because the liquid continually circulate and shock in mouth to make microbe attaching on the oral mucosa and dent out of mouth.if with the mingle of tongue,it can relieve the stink.

borax compound solution as traditional gargling liquid includes borax and bicarbonate yellow which has weak antimicrobial effect for skin and mucosa,it could not easily penetrate into skin and slowly discharge after absorption and being toxin after repeatedly having.

Strong acidic electrolyzed water generated from electrolyzed water generator which electrolyzed running water with 0.05% salt has killing bacterial properties(PH value 2.7,ORP〉1100mv,ACC 20-30mg/l).according to the reports:it can kill staphylococcus aureus,pseudomonas aeruginosa and escherichia coli in 1 minute,and kill candida albicans in 5 minutes,and bacillus subtilis var.niger in 20 minutes,and kill salmonella and vibrio sp. In 30 seconds.the oral infection is due to G-bacilli,anaerobic and candida albicans.the electrolyzed water has rapid and broad-spectrum killing ability from clinic practice.

Strong acidic water has the ability to activate the superficial cells,and to accelerate the cure,and touch with body to relieve the electron to down the ORP,and to restore the neutral PH value.it has no irritation and no odor for skin.because it can generatethe slight anaesthesia to relieve the hurt,it can be used the treatment of bedsore,infection and dermatitis.

Moreover,the strong acidic water can be reduce the running water in touch with light,air and organism.it is better to reserve in non-metal and close-space.for 30 days.it is better to use it when generates.

Strong acidic water has properties:broad-spectrum of killing microbe,rapid function,non-pollution,low-cost,good effect,non-irritation,non-odor.the editor suggest is can takes place of borax compound solution in the time of dental ulcer.
