  • periodontal pathogens proliferate in periodontal pockets located between the tooth and the tomb, resulting in the accumulation of plaque causing gingivitis.
  • the periodontal pocket is 9 ⁇ slightly deeper than the tooth * ⁇ 400 as shown in Fig. 35. Since the gums 400 are in close contact with the tooth surfaces 401, the inside of the periodontal pockets 402 cannot be printed with a normal toothbrush. It is difficult to control the accumulation of energy.
  • (1) is a reliable method, but such treatment can only be performed by a dentist due to the risk of gingival injuries, and is not a method that can be performed by a person at home and by himself.

And may not be perfect. 3 can be treated at home, but the gum surface is in contact with the tooth surface as described above. Since the periodontal pocket is closed when touched, it is difficult to flow water into the periodontal pocket even if the water pressure is increased, and the plaque effect is not so high. As a solution to these problems, there is a technology proposed as Japanese Utility Model No. 4-14733.

  • This device generates compressed water containing a large amount of water by discharging compressed air from the nozzle at the same time as water, and the inlet of the periodontal pocket is opened by the wind pressure of the atomized jet. At the same time, the water contained in the jet is forcibly poured into the periodontal pocket to wash away plaque, food residue and miscellaneous ⁇ in the periodontal pocket, and also to massage the gums by jet pressure. You can do it yourself.
  • the main purpose is to wash out black and food residues containing periodontopathogenic bacteria with a water-containing jet, so that water and compressed air with low pressure are required. Therefore, it is unavoidable to increase the volume of the water tank used for the stationary main body E.
