Are cysts the fault of the jaw, the dentist, or the patient?

Posted by Dental News Team On December - 4 - 2009

What are cysts, how do they form, and why do we only get them in certain places?

CystThere are many different types of jaw cysts. A cyst is an empty bubble wrapped in a thin membrane and found inside an organ or tissue.

-

Jaw cysts are found inside the bone, which is why they are often called bone cysts, or hard-body cysts. A distinction is made between congenital or acquired jaw cysts.

-

For example, follicle, globulo-maxillary and median lower jaw cysts are congenital cysts.

Periodontal or reticular cysts, on the other hand, are acquired.
-

Cysts are named according to the tissue they originated in, which also provides a clue as to how they form.

Let’s take a look at reticular cysts, which are usually caused by faulty root treatment. For example, if the roots were not filled to the tip, then cysts can form there even years later.

How?

Well, if root canal tissue was left over after treatment, it starts to rot and causes an inflammation in the bone. And this can stimulate tissue to grow.

Alternative medicine – ortho-molecular medicine – the latest hype?!

Posted by Dental News Team On December - 3 - 2009

Ortho-molecular medicine – an promising new method or just another way for the nutritional supplements industry to make a quick buck?

miteinanderYet another hype of the “holistic, alternative, or ortho-molecular” medicine kind!

The term „ ortho-molecular medicine“ was coined by Linus Pauling, an American chemist (1901-1994).  Ortho-molecular medicine is an alternative form of medicine based on the premise that the general population suffers from chronic vitamin and mineral deficiency and that illnesses can be prevented or healed by administering supplements.
-

Around the time that Pauling was doing his research, which was between the two World Wars (around 1930) this may truly have been the case (World War I took place from 1914-1918), but now things have changed. Illnesses such as night blindness (caused by a vitamin A deficiency), rickets (vitamin D), myopathy (vitamin E), Beri-Beri (vitamin B1), Pellagra (Niacin), scurvy (vitamin C) are illnesses that few European doctors have experienced first-hand. Our hospital beds are actually full of patients suffering from „affluenza“ or illnesses common in highly developed (affluent) societies. This includes high blood pressure, diabetes mellitus II, arterio-sclerosis, obesity, fat metabolism disorders and coronary heart disease.

-

Basically, we’re eating ourselves to death, but we are still under the impression that we have nutritional deficiencies … what?
Obviously just another rumour spread about by the nutritional supplements industry?

One of the reasons why ortho-molecular medicine is so successful may be that it generates such high profits. A FORSA study recently found that one out of every three people living in Germany takes nutritional supplements, adding up to an estimated annual turnover of 1 billion euros, just for  vitamin and mineral supplements. Pharmaceuticals companies are also jumping on the bandwagon.
-

ruheBut, like with many other alternative methods, there are as yet no truly scientific studies on the effectiveness of supplements. Still, the business of ortho-molecular training and treatment is booming. Medical associations even issue diplomas in „ortho-molecular medicine”. What are our doctors selling us – products which are not even approved by studies – meaning real studies, not „pseudo-studies“!
-

No proof without scientific studies
Whether we’re talking about traditional or alternative medicine, our opinion is clear. If there is scientific support (evidence-based studies) for the success of a specific kind of treatment, then this method should be used for the benefit of the general public – but assumptions and anecdotes cannot be used to treat patients. See the „Homeopathic treatment“ video at Checkdent.com
-

Why do we still feel like we are suffering from „deficiencies“?
But people still feel empty, exhausted, and overwhelmed. Why? Is it because we are living in an increasingly competitive and profit-oriented society, where virtues such as caring and empathy are being pushed aside by bullying at the workplace and profit maximization by industries (including the medical industry)? Are the sad, tired and frustrated faces that we see in the subways, cars and buses of our cities every day a result of the way we live? Not because of a vitamin deficiency, but because we no longer pay attention to our needs, ourselves and our own inner clocks?
-

One thing’s for sure, it’s not because you aren’t getting enough vitamins  – have a nice (work) day!

What makes our teeth move?

Posted by Dental News Team On December - 2 - 2009

Our body doesn’t like being put under pressure!

You know how it is when you press your thumb to your skin, the area turns white. This is because the blood vessels get squeezed together – leading to a temporary lack of blood, which makes the skin look pale. But it doesn’t matter if you only do this for a few seconds, after that blood circulation starts up again.
dekubitusBeing confined to a bed for a long time can have the same kind of effect, but worse – tissue can die, because this is not just a few seconds of pressure from the thumb, but the body’s own weight acting over a much longer period, which causes bed sores – as shown in this picture.

Obviously, pressure is bad. Now, the teeth „hang“ in the gums on a system of connective tissue, the desmodont. This desmodont consists of a multitude of little fibers strung up between the root and the bone. The motion of chewing turns into a tugging motion, tugging at the bone, that is!

desmodontTeeth start to move!

Teeth are not permanently set into the bone, they are „moveable“. If e.g. braces put pressure on a tooth, the desmodont can re-group, causing teeth to shift. This is how braces work, although our tongue and face muscles also put pressure on the teeth.

While the teeth tend to move together during adolescence (tertiary narrowing), as the lips and facial muscles continue to get stronger and exert more pressure, after about the age of 50 the opposite happens.

Lip pressure decreases, as does the tightness of the facial muscles (especially in the cheeks) and the tongue ends up exerting more pressure from inside the mouth. Moreover, recession of the gums, whether naturally or due to some illness (such as periodontosis) and the accompanying loss of bone, as well as  osteoporosis, means that the teeth are no longer as securely anchored in the jaw.

The front teeth start to fan out!

All of these factors cause the front teeth to slowly start to fan out. The teeth push forward, causing gaps to form. The longer this goes on, the quicker teeth start to shift, until the patient finally notices this and goes to a dentist.

Aligners are very effective in treating this displacement!
