Solutions for Stained Teeth

Stained, discoloured teeth are never as attractive as white teeth, even as they are sometimes in quite good health. These dental stains can be caused by foods and beverages like coffee, by smoking, by neglecting good dental hygiene, or simply because discoloured teeth are common in the individual’s family. There are several modern methods available to your dentist for removing, or at least reducing the discoursed stains. These include:

 

Teeth Whitening Camden

This uses bleaching gel to penetrate and whiten the teeth. The gel technique requires a barrier to prevent the gel from touching the sensitive gums, but is quite effective. It does require periodic reapplication, but patients can reliably have 6 months to perhaps a year worth of well whitened teeth.

At Grace Dental Clinic Camden residents can arrange to have regular teeth whitening as they arrange their regular bi-annual appointment.

At Grace dental we can also arrange kits for home teeth whitening Hoxton Park resident’s use.

 

Porcelain Veneers Dental Clinic Wetherill Park

Porcelain veneers are a permanent solution to stained/discoloured teeth, and are also useful for other cosmetic dental problems such as slightly misshaped teeth. The technique attaches a thin layer of porcelain over the front of the tooth, which looks healthy and natural and functions normally. Unfortunately, these veneers require part of the underlying natural tooth to be permanently removed. But the results themselves are permanent.

 

Laser Whitening Dental Clinic Miller

Laser whitening uses hydrogen peroxide to lighten teeth, with the laser acting as a catalyst to speed up the procedure. This allows for a fairly quick treatment, which patients prefer.

Some people show sensitivity to the laser light used in this technique, but for the most part it has even less problems than gel lightening.

 

Braces Camden

Teeth may need straightening as well as colour whitening. Talk to your orthodontist/dentist about braces or invisalign, and be one huge step closer to a perfect smile.

Adrenaline

taekwondoworld

It is a lesson learnt over and over again. We can prepare for an emergency, prepare for a possible street fight by training and honing our technique, and find that the real problem is the panic and stress in the moment of crisis. All the technique in the world is wasted if we freeze up at the moment we need to fight.

 

Individuals react differently to the adrenaline we experience in a crisis. Literature has been referring to the fight or flight response for generations, these being two completely different ways to handle a threat – escape of fight. Yet there are also individuals who physically faint, become emotional and burst out laughing, or who fight competently for 30 seconds before collapsing. This reaction is unpredictable; mentally strong people sometimes handle a sudden crisis poorly. How we deal with long term issues and a sudden surprise attack are very different things. Some individuals can master one without being able to deal with another.

 

Military warriors from all traditions had rituals that helped them prepare for battle. These were largely to deal with adrenaline issues. Meditation and other practices would not stop the adrenaline hit, but they helped the individuals deal with it positively. We can use the strength from adrenaline; it is part of our biology for a reason.

 

Of course, this only works when we know we are preparing for battle or competition. We are unlikely to anticipate a street confrontation, and will not be given time to practice deep breathing. So how do we prepare for the unexpected?

 

Self defence

Martial arts training need to include competition. There is a certain amount of adrenaline in competition, and this steadily teaches us to deal with the physiological and psychological aspects of adrenaline episodes. Some sports, like abseiling, can have a similar positive influence.

Those who do not compete, or at least expose themselves to some adrenaline inducing situations, are only receiving part of the training they need. Being able to handle ourselves means being able to handle the emotions of a crisis. Regular competition is a step in the right direction.

Equipment

Taekwondo training doesn’t entail buying weapons or armour like some martial arts. Indeed, part of the point is that you are always ready with the sills you possess. Yet there is still some basic equipment that is useful for Taekwondo Training.

 

Martial Art Mat.

The training centre should be well stocked with these. They are made of high density foam, usually about an inch thick. Larger surfaces may have the mats fitting together is a jigsaw pattern.

The better mats have a vinyl seal on them. This is an advantage as it is far easier to turn your foot on this surface.

 

Kick Bag

We don’t want to actually inflict pain on other people any more than we want to be receiving end when they do the inflicting. But we do want to practice our kicking, and condition out shins and feet well. A Kick bag is idea for this.

A kick bag should be heavy and tall. You need the weight to absorb the energy of the kick, and tall so you can hit it high and low.

 

Paddles & Pads

Energy is one thing, accuracy is another. We train to hit the target, and hit it hard. Paddles provide the smaller target for us to practice the accuracy or our kicks.

 

Chest Protector (Hogu)

For sparring. The name describes the function. It should include shoulder pads. Find something WTF approved

 

Helmet

This is mainly for actual competition rather than training, but if you intend to compete it help to be used to wearing the helmet.

Taekwondo Sydney

Whether is Karate Epping, Martial arts Glenwood or Taekwondo north Parramatta, we can all benefit from the mental and physical discipline of martial arts.

Hard Water And Limescale

Water may contain trace elements. We are lucky in Sydney to have good quality drinking water. Most of Australia also has decent water, though some isolated areas are not so lucky. The rest of the world suffers considerable variation.

 

Hard water contains a particularity large quantity of minerals, particularity calcium and magnesium carbonates. This water does not harm anybody’s health when consumed; in fact small amounts of the minerals are necessary and beneficial for our biology. But machinery and pipes can suffer long term effects from hard water.

 

If your household has accumulating lime scale in kettles, or similar build-ups on faucets, this is evidence of hard water. Water that does not form a lather is also evidence of hard water; the minerals in the water cause the soap to form a white solid ‘scum’. This is only a minor inconvenience in most situations; simple fixtures can have the mineral deposits periodically scraped off. But is can be a far more serious problem for complex machinery.

 

A heat pump hydronic or Hydronic buffer tank, as well as some piping materials, can accumulate mineral deposits over time. Unlike simple taps or other fixtures these cannot be easily cleaned. Machines with working parts may eventually be compromised by steadily accumulating mineral deposits.

 

Water can be softened if, necessary, with the addition of sodium of potassium ion. This is often the case with washing machines of water heaters. The additional softening component are added to the water through the washing detergent, or and ion exchange device can be used. If the water is being continually recycled through a piping system it only needs only be softened when first installed.

 

Talk to the installers of your Hydronic underfloor heating if you have hard water. Most installers will already be aware of the type of water in your suburb. The solution will probably just entail a minor modification of the Hydronic controls and valves when first installed.

Teeth

dentist-on-victoria

Teeth, or at least their outer enamel, are the hardest part of the human body. Teeth are also one of the longest lasting part of the body, providing we look after them. Our permanent teeth should last the rest of our lives.

 

The basic structure of a tooth falls into four parts, though this apparent simplicity is misleading as the complexities of tooth growth, structure, and regeneration are still under study. The tooth enamel is the outer part of the tooth. It is mostly hard mineral with some water and organic material. Because this enamel is semi-translucent the colour of the material beneath, either the natural dentin or artificial filling, affects the colour of the tooth.

 

Dentin is the material beneath the enamel. It is a porous, yellow material consisting mostly of 70% inorganic material. Being softer than enamel it is more prone to decay that the outer surface of the tooth. The dentin material has many tiny tunnels, about 1 or 2 micro-meters, running form the pulp to the enamel. Each of these tunnels is separate from each other. Recent studies have speculated on liquids flowing through these tunnels, from the pulp to the outer enamel, which may affect both general tooth health and resistance to decay.

 

The pulp (or nerve) is in the middle of the tooth, surrounded by another layer called the Cementum. The cementum is similar to the dentin, but has more organic material, something which allows the tooth to attach itself to periodontal ligaments for stability. The pulp inside the cementum supplies the tooth with moisture and nutrients, and also provides the physical feeling for the tooth. Temperature, external pressure and damage to the tooth (such as decay) are felt through this pulp.

Martial Arts Advice I Heard from Long Term Players

  • Keep your mouth Open, or at least don’t clench your teeth. The correct way to breath is through the nose, and we don’t want people to look like stunned fish by mouth breathing. But clenching your teeth will make you tense. Breathe normally and be naturally relaxed.
  • There are diminishing returns for any endeavour. Putting in effort will reap results, but after you reach a certain effort threshold there is less improvement. Three classes a week of two hours duration seems the most effective amount of tuition. A forth class per week will not help much beyond this.
  • Shoulders should be in front of the chest.
  • People emphasis balance, but this can backfire. If you never have trouble with balance, don’t distract yourself. But if balance is sometime an issue, learn to balance yourself intuitively.
  • Listen first, ask questions later. Asking questions lets you clear up your perspective on the situation. But never interrupt a class; wait till the right moment.
  • Many people instruct to pivot on the heel. This has been questioned in the last few years because the physics of the body suggest there might be better alternatives. The front of the foot might be better, or sometime the centre of the foot. It might depend on the move you are executing.

 

Martial Arts have not remained static. Situations change (we rarely attack people on horses anymore), phases come and go, better ideas develop over time, and tall people find that they have to change the techniques that were developed by shorter masters. Any specific advice might prove invaluable, or it might end up being discredited. But being open minded, flexible, yet still not carried away foolish ideas, is always a good approach

Some Myths

Ryde medical Imaging

Pregnant women cannot be X-rayed

This is not completely true. X-rays are not performed during the first three months of pregnancy, but some X-rays are possible after this time, using protective measure for the foetus.

 

Diagnostic Imaging Involves Radiation.

Some imaging such as X-rays and CT scans involve radiation, as do mammograms and catheterization. Other medical imaging methods are not connected to radiation at all, such as MRI (magnetic based) Ultrasound.

 

MRI is the best type of scan.

It depends on the situation, though MRI is often the best because of the details it shows. But MRI usually takes 30 minutes to produce a result. Sometimes results are needed quickly, and other methods are used. MRI is often the first choice, but not always.

 

X-rays are old fashioned and out of date.

X-rays have stayed with medical technology, even as other medical methods have been superseded. About half the medical imaging produced is X-ray based. Modern technology has made X-rays quick with much lower radiation does than earlier methods.

 

Radiation is dangerous.

This is partially true, but exaggerated. We are exposed to background radiation all the time. Radiation is greatly increased by plane travel or Sun exposure. A standard X-ray has about the same radiation that we receive on a normal day. The increase in radiation from an X-ray is only slightly above the normal daily exposure. And X-rays are only used when there is a medical issue, which is usually far more of an immediate threat than the small dose of radiation.
