			In [[fluid dynamics]], a '''barotropic fluid''' is a fluid whose density is a function of only pressure.<ref>{{cite book \|last=Shames \|first=Irving H. \|title=Mechanics of Fluids \|year=1962 \|publisher=McGraw-Hill \|url=http://books.google.com/books/about/MECHANICS_OF_FLUIDS.html?id=Ben6FKoTzSMC \|accessdate=8 November 2012 \|lccn=61-18731 \|page=159 \|quote=It <math>\rho{}</math> is expressible as a function of <math>p</math> only, that is, <math>\rho = \rho{}(p)</math>, the [<math>\int_0^p \frac{dp}{\rho{}}</math> in Eq. 5-66] is integrable. Fluids having this characteristic are called ''barotropic fluids''.}}</ref> Barotropic fluids are useful model for fluid behavior in a wide variety of scientific fields, from meteorology to astrophysics.

			Most liquids have a density which varies weakly with pressure or temperature, i. e., the density of a liquid is nearly constant, so to a first approximation liquids are barotropic. To greater precision, they are not barotropic. For example, the density of [[seawater]] depends on temperature, salinity, and pressure, but only by a few percent at most.

			In [[astrophysics]], barotropic fluids are important in the study of stellar interiors or of the interstellar medium. One common class of barotropic model used in astrophysics is a [[Polytropic process#Polytropic fluids\|polytropic fluid]]. Typically, the barotropic assumption is not very realistic.

			In [[meteorology]], a '''barotropic atmosphere''' is one in which the density depends only on pressure, so that [[Isobaric process\|isobaric]] surfaces (constant-pressure surfaces) are also [[isopycnic]] surfaces (constant-density surfaces). The isobaric surfaces will also be [[isothermal]] surfaces, hence (from the [[thermal wind equation]]) the [[geostrophic wind]] is independent of height. Hence the motions of a rotating barotropic air mass or fluid are strongly constrained. The tropics are more nearly barotropic than mid-latitudes because temerpature is more nearly horizontally uniform in the tropics.

			A '''barotropic flow''' is a generalization of the barotropic atmosphere. It is a flow in which the pressure is a function of the density only and vice versa. In other words, it is a flow in which isobaric surfaces are isopycnic surfaces and vice versa. One may have a barotropic flow with a non-barotropic fluid, but a barotropic fluid must always follow a barotropic flow. Examples include barotropic layers of the oceans, an isothermal ideal gas or an [[isentropic]] ideal gas.

			A situation which is not barotropic is [[Baroclinity\|baroclinic]], i. e., pressure is not enough to specify density. For a barotropic fluid or a barotropic flow (such as a barotropic atmosphere), the [[Baroclinity#Baroclinic vector\|baroclinic vector]] is zero.

It is very common to have a dental emergency -- a fractured tooth, an abscess, or severe pain when chewing. Over-the-counter pain medication is just masking the problem. Seeing an emergency dentist is critical to getting the source of the problem diagnosed and corrected as soon as possible. Here are some common dental emergencies: Toothache: The most common dental emergency. This generally means a badly decayed tooth. As the pain affects the tooth's nerve, treatment involves gently removing any debris lodged in the cavity being careful not to poke deep as this will cause severe pain if the nerve is touched. Next rinse vigorously with warm water. Then soak a small piece of cotton in oil of cloves and insert it in the cavity. This will give temporary relief until a dentist can be reached. At times the pain may have a more obscure location such as decay under an old filling. As this can be only corrected by a dentist there are two things you can do to help the pain. Administer a pain pill (aspirin or some other analgesic) internally or dissolve a tablet in a half glass (4 oz) of warm water holding it in the mouth for several minutes before spitting it out. DO NOT PLACE A WHOLE TABLET OR ANY PART OF IT IN THE TOOTH OR AGAINST THE SOFT GUM TISSUE AS IT WILL RESULT IN A NASTY BURN. Swollen Jaw: This may be caused by several conditions the most probable being an abscessed tooth. In any case the treatment should be to reduce pain and swelling. An ice pack held on the outside of the jaw, (ten minutes on and ten minutes off) will take care of both. If this does not control the pain, an analgesic tablet can be given every four hours. Other Oral Injuries: Broken teeth, cut lips, bitten tongue or lips if severe means a trip to a dentist as soon as possible. In the mean time rinse the mouth with warm water and place cold compression the face opposite the injury. If there is a lot of bleeding, apply direct pressure to the bleeding area. If bleeding does not stop get patient to the emergency room of a hospital as stitches may be necessary. Prolonged Bleeding Following Extraction: Place a gauze pad or better still a moistened tea bag over the socket and have the patient bite down gently on it for 30 to 45 minutes. The tannic acid in the tea seeps into the tissues and often helps stop the bleeding. If bleeding continues after two hours, call the dentist or take patient to the emergency room of the nearest hospital. Broken Jaw: If you suspect the patient's jaw is broken, bring the upper and lower teeth together. Put a necktie, handkerchief or towel under the chin, tying it over the head to immobilize the jaw until you can get the patient to a dentist or the emergency room of a hospital. Painful Erupting Tooth: In young children teething pain can come from a loose baby tooth or from an erupting permanent tooth. Some relief can be given by crushing a little ice and wrapping it in gauze or a clean piece of cloth and putting it directly on the tooth or gum tissue where it hurts. The numbing effect of the cold, along with an appropriate dose of aspirin, usually provides temporary relief. In young adults, an erupting 3rd molar (Wisdom tooth), especially if it is impacted, can cause the jaw to swell and be quite painful. Often the gum around the tooth will show signs of infection. Temporary relief can be had by giving aspirin or some other painkiller and by dissolving an aspirin in half a glass of warm water and holding this solution in the mouth over the sore gum. AGAIN DO NOT PLACE A TABLET DIRECTLY OVER THE GUM OR CHEEK OR USE THE ASPIRIN SOLUTION ANY STRONGER THAN RECOMMENDED TO PREVENT BURNING THE TISSUE. The swelling of the jaw can be reduced by using an ice pack on the outside of the face at intervals of ten minutes on and ten minutes off.
