PURPOSE:To improve the sterilizing performance of dental treatment machine equipment by switching the water from a water supplying source to an acidic ionic water from an electrolytic ionic water generating means and guiding it to a dental treatment means. CONSTITUTION:An electrolytic ionic water generating means 3, an acidic ionic water supplying means 4, and a salt water supplying means 5 are provided in a housing 2 on the lower part of a treatment base, and a three-way cylinder 5 and micro motor hand piece 7a for dentist are provided on the treatment base. To sterilize dental treatment means 6-16, a switch 47 is operated to control an electromagnetic switching valve 46, and an acidic ionic water is supplied through a pipe line 48 to a pipe line 17. After the sterilization, the electromagnetic switching vale 46 is operated to supply tap water from a pipe line 45, and the acidic ionic water present in the dental treatment means 6-16 is discharged. The corrosion of the dental treatment means 6-16 is prevented, and the acidic ionic water is prevented from being put into the mouth of a patient. |
