How a Tooth is Decayed?

You might have listened to the term tooth decay from many people. Actually speaking, what does it mean? How a tooth gets decayed? Are these certain questions you often think? Then, go on to find the answers for them.

A tooth decay is a process which results in formation of a cavity in the tooth. A tooth consists of a pulp chamber consisting of nerves and blood vessels. It is covered by two layers, the outer enamel and inner dentin layer. The enamel is the hardest crystal like layer on the tooth. The dentin and the enamel protects the inner pulp chamber which is the living part of the tooth.

Bacterial growth in the oral cavity is induced with improper oral hygiene. Exposure of bacteria to sugars or other carbohydrates makes acid. The crystal-like substance on the outer surface of the tooth gets affected with the acid. This process is termed as demineralization. It is indicated by the sign of white spots on the surface of the tooth. However, the decay at this process can be stopped by use of fluorides at home and dental office. If the decay continues further, the enamel breaks down which is difficult to treat on self. The formed cavity is cleaned and cured by a dentist. Upon further decay, the dentin which is the layer inwards to the enamel, gets damaged. From there, the infection or decay can reach the tooth's pulp. Infection in pulp can result in abscess (swelling) or fistula (opening of the surface of the gum).

No symptoms are associated with tooth decay until a cavity is formed or the tooth gets infected. However, upon initiation of cavity or infection, severe toothache is seen in the infected persons. With negligence of treatment, tooth decay can lead to further infection and even tooth loss.

Know About Trading Basics

Trading is the process of buying and selling of commodities, securities within a country or between countries. It is generally a short term activity done for making quick profits. For performing a trade, it is very important to have a basic understanding of how the markets works.

Basically financial markets are divided into two types - primary markets and secondary markets. Primary markets consist of newly issued shares created by the companies through Initial Public Offering (IPO). And the secondary markets consist of the shares that have already been issued by the companies previously. These shares can be traded without the involvement of issuing company and when people speak of the stock market they are talking about the secondary market, not primary.

There are two basic ways to execute a trade - On the exchange floor and the electronic or online markets. In the exchange floor, we can get the information about the markets using television and newspaper. In this exchange floor, the broker finds floor traders and execute the trade between them. In this process the broker acts an intermediate between the traders and calls the final price and executes the trade.

The electronic markets make use of vast computer networks to connect buyers and sellers all over the world. The NYSE handles a small percentage of its trading electronically, while its rival NASDAQ is completely electronic. Many large institutional traders, such as pension funds, mutual funds, etc. prefer this method of trading. Here the broker accesses the exchange network and the system finds a buyer or seller depending on your order.
