With the progress of science and technology, it is inevitable that there will be leapfrog products in various consumer categories. Dental flushes (water flosser) play such a role.In the 1950s, American dentist Gerald Moyer and engineer John Mattingly jointly invented Water Flosser (Water Flosser), which was officially commercialized in 1962. It has been widely recognized as a highly effective cleaning agent.The principle of Water Flosser has been roughly explained above: water flow (5-90 psi(34-621kPa)) or pressure spray is used as the cleaning medium, and specially designed nozzle is used to clean the supragingival biofilm, subgingival plaque, and the residual debris in the tooth gap.The high-pressure water jet to the tissue surface forms two hydrodynamic regions, namely, the impact area where the water column first contacts the oral tissue and the washing area formed by the concentric circle of water diffusion. These two regions dilute and fully wash the subgingival plaque, especially the non-adherent subgingival plaque.The gentle, comfortable and effective cleaning of the water can play an important role in the maintenance of oral hygiene for ordinary people as well as specific populations, such as periodontal disease, orthodontics, implant and fixed dentures, and diabetic patients.In my opinion, the biggest advantage of Water Flosser is that it's easy to learn: For people who don't floss or have complicated teeth, hold the handle of Water Flosser, place the teeth between the teeth, press the switch, and wash them one by one -- half a minute is all.Water flosser is popular in developed countries in Europe and the United States because it doesn't wear your hands out, or you don't have to worry about damaging your teeth or widening your gaps.In the academic world, the effect of water flosser on plaque control and alleviation of gingival inflammation has also stood the test of many studies. For example, the study results of Lyle et al showed that the application of water flosser could reduce plaque biofilms on the dental surface and reduce the number of pathogenic microorganisms in the periodontal pocket within 6mm.Li Chanxiu et al. found that water flosser had a certain effect on maintaining oral hygiene, inhibiting plaque and controlling gingival inflammation in elderly patients with periodontal disease.Xie Le et al. confirmed that pressure spray dental rinsing device can significantly reduce plaque attachment and improve gingival inflammation in patients with periodontal disease, and is an effective auxiliary oral cleaning device for patients with periodontal disease.Today, the demand for Water Flosser is expanding, and the technological iteration of dental rinsing device is also going on rapidly.At present, the mainstream water floss in the market adopts two technologies: high pressure water flow pulse or micro-explosive air flow.The high pressure water pulse is driven by a water pump, and the water passes through the nozzle and then impinges on the mouth with a pulse jet. The principle is similar to the "high pressure cleaning machine" used in car washing. At present, most of the Water Flosser products on the market adopt such technology.Microblast technology works like a high-pressure air gun, but the pressure is never high enough to damage tissue -- you blow food debris out of your teeth, and then you wash the debris away with water.
