Nosebleeds may mean something much more serious: an introduction to HHT

Article Abstract:

Dentists may be the first ones to identify patients with hereditary hemorrhagic telangiectasia (HHT), which is also called Rendu-Osler-Weber syndrome. HHT is a genetic disorder caused by a defect in the formation of capillaries, which connect arteries and veins. This results in the formation of thin-walled arteriovenous fistulas, which bleed easily. This causes small cherry-red spots, which often occur on the tongue, lips, gums or eye. Nosebleed is very common in these patients. Malformations can also occur in the brain, lungs and gastrointestinal system.

Posts: necessary or unnecessary?

Article Abstract:

It is not always necessary to put posts in a tooth that has received root canal therapy. If the tooth had no fillings or minor fillings and still retains up to half of the crown, a post may be unnecessary. If more than half the crown is missing, a post is probably necessary. Posts were once thought to strengthen the tooth but may actually weaken it. Most posts are now prefabricated rather than custom-cast and are usually made of nickel-chrome or a titanium alloy. Metal posts are commonly used, but other more flexible types of posts are under development.

Why clean your tongue?

Article Abstract:

The surface of the tongue contains food particles and millions of microorganisms that may contribute to bad breath. The microorganisms may also cause tooth and periodontal disease. Although most people clean their teeth adequately, tongue cleaning is much less common. Several companies have designed tongue cleaners that are small, cheap and easy to clean. Studies have shown that these cleaners are more effective than a toothbrush in cleaning the tongue. A technique for cleaning the tongue is described.
