With the increasing awareness of oral hygiene, various types of oral cleaning tools are in succession. The tooth cleaning device is used as a common oral cavity cleaning tool, and can realize the cleaning of the oral cavity by spraying water to the tooth surface and the adjacent surface of the tooth, when the tooth cleaning device is used, a user is required to automatically control and adjust the movement of the spray head into the oral cavity so as to adjust the spraying direction of the water flow, and the effective cleaning of all parts in the oral cavity is difficult to ensure. Therefore, the positional relationship between the rinse head and the tooth surface and the tooth gap should be limited to a certain extent during consumer operation, ensuring that a proper shear force is generated when the rinse reaches the tooth surface. Secondly, current tooth flusher all adopts single water column, can't be according to the form of patient's slit size adjustment water column's size, guarantees the fluid shear force that more effectively utilizes rivers to produce.

It was found that when rinsing teeth from a single direction, the fluid shear force was reduced sharply below the point of contact [25]. When the tooth gap is irrigated, if the tooth gap can be irrigated from two directions of the cheek and tongue, the fluid shearing force on the two sides of the cheek and tongue can be ensured, and meanwhile, the multidirectional fluid shearing force generated by collision of two water columns can ensure the cleaning of the lower part of a contact point and the upper part of a gingival valley region.

Dental ultrasound refers to a high frequency sonic technique applied in the dental field. The cleaning device utilizes the sound wave vibration with specific frequency and the impact force of water flow to enhance the cleaning effect, is used for removing pathogenic factors such as dental calculus, bacterial plaque and the like, and is used for root canal flushing in root canal treatment and removing necrotic tissues, sapropel plaque and the like of dental enamel in tooth surface preparation, thereby providing preparation for subsequent repair or filling.

The water flow and the sound wave vibration are combined, so that the liquid flow is increased, the fluid shearing force is increased, and dental plaque can be removed through the cavitation effect, the vortex effect and other physical effects. Therefore, the ultrasonic combined tooth-flushing device is a promising application direction.
