Dental Dry Vacuum Function
If you have been to a dentist, you have probably seen a dental dry vacuum in action. Dental dry vacuums are the little suction tubes that the dentist places in your mouth to help suck up saliva and other fluids. These dry vacuums usually have a flexible plastic end as the end piece, which allows the dentist to hang them from your mouth or change the angle to get at all recesses of the mouth. Their ability to remove liquid from your mouth helps the dentist in two ways. By removing excess fluid, these vacuum pumps improve visibility, so your dentist can see what he is doing. They also assist in cleaning out the mouth, as often dentists will use a water rinse to help get plaque and bacteria out once he has cleaned the mouth.
Dental Dry Vacuum Mechanism
Dental dry vacuums have two main functional parts: the actual vacuum and the mouthpiece. The vacuum works by pumping air out of the central compartment. This generates negative air pressure within the compartment (relative to atmospheric pressure), causing air to rush in through the mouthpiece, which is the "open" end. The mouthpiece is connected to the central compartment via a long tube that has an airtight seal. This means that the only way for air to get into the central compartment is the open end of the mouthpiece, which causes the machine to generate suction at that open end of the mouthpiece. This suction then pulls in air and liquid from your mouth as the dentist works.
Advantages of Dry Vacuums
One of the main advantages of using a dry vacuum for dental work is the relative energy efficiency; it is far easier to pump air and generate negative pressure that way than it is to pump liquid out of a container. This method also allows for the liquid waste to be stored and then disposed of carefully, as it could be biologically dangerous. In addition, the negative pressure generated by a dry vacuum is sufficient to suck down liquids but is not strong enough to cause damage to the soft tissues of the mouth.
