Countries affected by H1N1 influenza

Swine Flu is in fact a mutated form of the common flu, which behaves like a seasonal influenza- H1N1 influenza is made up of genetic elements of four rather common flu virus. H1N1 is a type A virus, the most virulent human pathogens known that cause the most severe disease among humans. Type A viruses are more prone to widespread outbreak (as H1N1 has spread to 74 countries now). It is no surprise that airports and hospitals around the world have set up screening areas and quarantine rooms for suspected influenza carriers, so be prepared if you are planning on traveling, especially to a densely populated country. It is natural that lesser developed, densely populated countries must take flu pandemics seriously as they often lack the technology, medical manpower and/or resources necessary to keep a potentially large outbreak under control.

Swine Flu spreads faster but is less fatal than Bird Flu.

Although H1N1 influenza is currently present and spreading in both pigs and humans, and can spread quickly and silently from human-to-human, it is not transferable by eating cooked pork – don’t panic over that BLT! The CDC advises using regular soap and water or an alcohol-based hand cleanser frequently to clean your hands before touching your facial features (like the eyes, nose or mouth) to lower the risk of catching the flu.

“Normally the influenza virus is spread from person to person through droplets in the air — from a person with a cough for example,” said Dr. David Satcher, a professor at the Morehouse School of Medicine and former U.S. Surgeon General. Droplets in the air can be inhaled by another person, which is probably the most common way a virus spreads.

Also posing a risk, he said, are items that have recently touched or handled by someone infected with the flu – a fork or a doorknob, for example. Some experts endorse occasionally disinfecting household surfaces and appliances with a diluted chlorine bleach solution.  You should also disinfected your toothbrushes by soaking them in an OTC strength hydrogen peroxide ( 3% H2O2) for 10 minutes – or get new tooth brushes.
Once infected with the flu, it’s difficult to know what actual strain of influenza you may have. H1N1 flu symptoms are similar to the common flu: fever, cough, sore throat, body aches, headache, chills and fatigue. It can be difficult to distinguish between the common cold and influenza in the early stages of  infection, so if you experience any of these symptoms for a prolonged period, consider a visit to your primary health care physician for a check-up.

Tooth development is a complex process by which form from embryonic cells, grow and emerge into the mouth. The key to a healthy oral environment in which teeth can thrive, enamel, dentin, cementum and periodontium must all develop properly at the right time during fetal development. Baby (primary) teeth begin to develop at the 6 – 8 week mark in the womb. Adult (permanent) teeth develop at the 20 week mark in the womb. Formation of tissues within the branchial arch is the process that actually initiates tooth development. During pregnancy, proper prenatal care is essential for the future smile of the young life.

There are four stages your teeth develop into before becoming fully fledged teeth. The first stage, the bud stage, is characterized by the appearance of a tooth bud with no clear cell arrangement. This stage occurs when the fetus is approximately 6 weeks old. The second stage, the cap stage, is when cell arrangement becomes evident. Extracellular substances are produced resulting in an aggregation of these cells, as the tooth bud takes on the appearance of a cap, and becomes the enamel (dental organ). This is also the stage when supporting structures of the tooth are developed. The third stage, the bell stage, is characterized by a bell-shaped dental organ. The bulk of the tooth’s biological development and maturation take place during this stage. The final stage, the crown stage, is when tissues (like enamel and dentin) are hardened and important cellular changes occur, including adding new material to the outer developing surface of the  tooth. Dentin formation, called dentinogenesis, is the first discernable sign of the crown stage, and occurs before enamel can be formed. Enamel formation, called amelogenesis, occurs after dentinogenesis. Environmental influences (like if the child suffers from fever, or is taking tetracycline antibiotics) can cause discoloration of permanent teeth.

Tooth eruption, which occurs between 6 months and two years of age, is the process of tooth development when teeth break the gum layer and become visible. Primary teeth stay in the mouth until around 6 years of age, at which point they are gradually replaced by permanent teeth. The first set of permanent teeth come in behind the twenty primary teeth at age 6. Sealant can be placed on to these teeth to prevent tooth decay. The last primary teeth will exfoliate around age 12 to be replaced by second bicuspids. This is called the mixed stage, when both primary and permanent teeth are present. Orthodontic treatment can be performed at the mixed stage; the most common age to receive braces is between 9 and 12.

The 3rd molars erupt around age 16 to 18. This is the stage when people are supposed to be wiser, so they are called wisdom teeth! Due to evolution, only one out of every 25 people have a jaw size that can accommodate all 32 teeth, so most of us need to have our wisdom teeth removed (lest problems be created with crowding or crooked teeth, which can lead to tooth decay and gum problems). Most of us have 28 teeth; with proper care, all 28 teeth can be kept throughout our life!

If you end up missing one or more permanent teeth, proper restorations should be made to assure the adequate support of your facialmuscular system to maintain its health. Such restorations will also help to prevent oral conditions from deteriorating due to shifting or tilted teeth (causing difficulty in maintaining healthy oral conditions). There are options for missing tooth problems; be sure to consult with your dental professional!
