Can you safely fill your own cavity?
You CAN but only temporarily (like if yours falls out on Friday night but you can't go to the dentist til Monday) drugstores sell filling paste , its kept near the toothpain stuff like orajel and antiseptic rinse...its only $2 or $3 and you mix it yourself, or its premixed, you just roll it into a ball, stuff it in the cavity using a special little spoon that's provided, and let it harden, I find that if you chew on a piece of cloth (like tshrt) it hardens and tampers down way easier. Tada. All done. mY MOTHER HAD ONE LAST LIKE 10 YEARS, not reccomended tho
Answer #2:
You cannot repair your own cavities yourself however you can temporarily fill them with the paste that the first answer describes. The paste is actually for temporarily replacing lost fillings or temporarily repairing loose caps and should never be used as a permanent fix. Cavities are caused by thinning enamel (Layer of minerals outside of teeth) allowing bacteria to get to the dentin (The actual bone part of teeth). This bacteria breaks down the dentin. It is a real bacterial infection, however it cannot be cured via anti-biotics because it is not really tissue so no white blood cells are able to get to the infection. The way dentists repair cavities is by grinding away all of the infected parts of the enamel and dentin so it cannot spread farther, then they fill the missing parts of the tooth with a material made of gold, porcelain or a silver amalgam (Zinc, silver, tin, copper and lead) or a glass resin.
Filling a cavity with the stuff you can buy in stores will not stop the infection from progressing. When a tooth has a hole in it, this allows bacteria to get to the dentin or the pulp (Nerve-like center of the tooth). Because it is not protected by the enamel, an infection can start extremely easily and you do not want an infection spreading into the pulp as it causes extreme pain and will require a root canal or pulpectomy. This stuff allows you to temporarily fill it so an infection won't start until you can get the filling replaced.
However, filling a hole in an infected tooth can stop or slow the pain of a bad infection but if you have an infection in the pulp you should not fill it. When white blood cells fight an infection as they will for an infection in the pulp, it creates pus which is dead white blood cells (Leukocytes). Filling a tooth while you're fighting off the infection can cause a build up of pressure from the pus which will put pressure on the nerve causing extreme pain.

How dangereous is a leaking valve in heart of young child?
It matters which valve is leaking, how much is leaking and the cause of the leak. It can be fatal but could be repaired depending on the condition of the valve and the particular valve affected. It is not wise the let the child to get overexerted and it is best to have a cardiologist determine all the variables involved with that particular child.
When the heart beats, some of the blood in the left ventricle (which has received oxygen from the lungs already) is able to flow through the hole in the septum into the right ventricle. In the right ventricle, this oxygen-rich blood mixes with the oxygen-poor blood and is directed via the pulmonary artery back to the lungs.
The pericardium is a tough double layered fibroserous sac which covers the heart.
The space between the two layers of serous pericardium the pericardial cavity, is filled with serous fluid which protects the heart from any kind of external jerk or shock.
How do nurses read heart beats using trigonometry?
Trigonometry helps nurses read the heart beats on an EKG because an EKG shows the heartbeats in a graph.
False
Blood gets oxygen in the cells. This is part of the body system.
Is there is mixing of blood from right to left side of heart normally?
No because the valves present between the right atria and left atria (interartrial valves ) and the valves present between the right ventricle and left ventricle (interventricular valve ) allow the unidirectional flow of blood only ;
Is profuse sweating with little exertion at sign of heart problems in a female?
For anyone it may be. See doctor then if ok start exercise routine. It will get better if u lose weight etc. did for me
What are ventricles doing atrial systole?
During atrial systole, the SA node ( power house for heart to keep on beating) is unable to send signals to ventricles. But heart has some back up power houses which take over, so the ventricles can still keep on beating but at a slower rate than normal during atrial asystole.
How are the cells in the biceps alike to the cells of the heart?
They are both made up of muscle cells. The heart is made of cardiac muscle, and the biceps are made of skeletal muscle.
