Spraying tools are small spray guns, large high-pressure spray guns used to extinguish the fire. In order to be suitable for all kinds of physiological environment of the oral cavity and achieve the best cleaning effect, let's take a look at the technical content of the Water Flosser.
1. Significance of Pulse Pressure Pulse and water pressure are the key mechanisms for the Water Flosser to play a cleaning role. The combination of the two on the tooth surface and periodontal tissue can produce the alternating effect of pressure and decompression. During the pressure stage, water rushes into the adjacent tooth space and inside the periodontal pocket, while the decompression stage facilitates the smooth outflow of food residues and bacteria. Therefore, compared with the constant water pressure Water Flosser, the Water Flosser can remove dental plaque and food debris more effectively, and massage the gums. Early studies have shown that pulsed, high-pressure water is three times as effective at cleaning as non-pulsed water. A pulse rate of 1 200 beats /min combined with water pressure of 55-90psi(379-621kPa) resulted in relatively complete plaque removal. Therefore, the Water Flosser directly connected to the faucet is not pulse water pressure, of course, it has cleaning power, but the specific cleaning efficiency remains to be studied.
2. The significance of water pressure
Safety is the premise of the promotion of the Water Flosser. Different people's gingiva texture is different, we according to the thickness of the gingiva is divided into thin gingiva type and thick gingiva type two types. Thin gingival type is more susceptible to periodontal disease, poor resistance to gingival inflammation, more prone to damage and bleeding for mechanical force, and even the possibility of gingival retreat. The resistance of thick gingival type to periodontal disease is stronger than that of thin gingival type, and it is less prone to gingival bleeding and gingival receding. For the same person, normal gums are pink and tough. After inflammation occurs, the gums will change in color, becoming bright red or dark red, brittle in texture, more sensitive to mechanical forces, and more prone to pain and bleeding.
A large number of clinical studies have confirmed the good tissue safety of Water Flosser since they were introduced in the 1950s, and no obvious adverse reactions have been found. Early studies have shown that healthy gum tissue can withstand 90 psi(621 kPa) of irrigation pressure, while 50 to 70 psi(345-483 kPa) of irrigation pressure is recommended for gums with inflammation or ulcers. Cobb et al. flushed the periodontal pockets of patients with periodontitis with a pulsed Water Flosser at 60 psi(414 kPa) for 8 s. The histological examination under electron microscopy showed that there was no obvious abnormity between the epithelial morphology of the irrigated site and the unirrigated site. So the optimal water pressure is different for different people. People with thin gingival types and those with inflamed gums should use gentle water pressure, while people with thick gingival types and those with healthy gums should use normal water pressure. This shows how important it is to have a different water pressure gear. Water pressure is too small cleaning strength is not enough, cleaning efficiency is reduced. Water pressure can damage the gums. For patients with periodontal disease, we recommend a irrigation pressure of less than 30psi, which is safer for the periodontal tissue.
