Abstract: Carbon dioxide is supplied from a carbon dioxide cylinder (15) to a pressure vessel (13) through reducing valves (18 and 19). The pressure vessel (13) is also supplied with a sodium hypochlorite water solution having a desired concentration through a material supply pipe (12). The material supply pipe (12) is connected to first and second branch pipes (100 and 101) through a distribution valve (102). The sodium hypochlorite water solution supplied through the material supply pipe (12) is partially sprinkled to a gas-phase region in the pressure vessel (13) through the first branch pipe 100, while the remainder of the sodium hypochlorite water solution is supplied to a liquid-phase region in the pressure vessel (13) through the second branch pipe (101). The pressure vessel (13) is provided with a liquid level retention mechanism (25 to 29) is provided to retain the liquid level in the pressure vessel (13) within a constant range.

Abstract: The upper end of a cylinder (8) located in a mouth (3) of a bottle (2) abuts the top plate (5b) of a seal cap (5). The cylinder (8) has formed in the outer surface thereof a circumferential recess (10) normally sealed by a sealing member (9). The bottle (2) contains hydrochloric acid (second component) of a diluted concentration, while the circumferential recess (10) in the cylinder (8) contains sodium hypochlorite as a first component. When a user removes a stopper ring (6) and next turns the seal cap (5) in the tightening direction, the circumferential recess (10) moves to and below the sealing member (9) and permits the first component to flow into the bottle (2) and mix with the second component. As a result, sterile water of a pH level within the slightly acidic or neutral region is produced. Then, the user can use the prepared sterile water for sterilization by hypochlorous acid.

The resulting sterile water has a pH level within the slightly acidic or neutral region and a predetermined effective chlorine concentration around 50 to 300 ppm, for example.

Abstract: A dental treatment apparatus having a sterilized water producing unit placed in a water circuit of a dental chair unit. The sterilized water producing unit electrolyzes water mixed with sodium chloride and hydrochloric acid in a diaphragmless electrolytic cell to produce sterilized water having a residual free chlorine concentration adjusted in the range of from 1.0 ppm to 200 ppm and a pH adjusted in the range of from 3 to 7. The dental treatment apparatus further has a water circuit switching controller that alternately switches between raw water and feed water from the sterilized water producing unit.
