Overview Of Teeth

Teeth are extremely useful. They help you to tear, cut and break up your food into very small pieces so you can swallow it more easily. Digestion starts in your mouth with your teeth.

However you don’t need them to survive.

Irreversible and Reversible Pulpitis [K04.0]

Reversible pulpitis:

Symptoms: typically include pain upon eating or drinking something very sweet, hot, or cold. Without treatment, the inflammation can progress to a dental abscess, a collection of bacteria and pus.

Prevention:

Good oral health habits can help offset it, but in many cases, a filling is eventually needed. Pulpitis can also occur if you crack or break a tooth.

Irreversible pulpitis:

Symptoms: include sudden intense pain. Left untreated, it can result in a widespread gum and connective tissue infection.

Treatment:

Irreversible pulpitis is generally treated with a root canal procedure. If that doesn't work, your dentist may have to remove the tooth.

Pulp polyp. An inflamed nodule of granulation tissue can be seen growing from the pulp chamber of this broken down first permanent molar.

Hyperdontia is having an excess number of teeth. A person who develops more than 20 primary teeth or more than 32 permanent teeth has hyperdontia. The additional teeth are referred to as supernumerary teeth.

Hyperdontia effects about 1% and 4% of the population.

Male to female ratio of 2:1; the majority of cases are limited to a single tooth.

Associated with:  Gardner syndrome, and cleft lip and palate.

Hyperdontia [K00.1]

Causes: The cause is still unknown , however it may be cause by, overactivity of

the dental lamina during tooth development, or other developmental

factors.

Microdontia is having abnoramally small teeth.  The most common teeth affected are the upper lateral incisors and third molars.

Macrodontia is having abnormally

large teeth.It can occasionally be seen in people

with pituitary giantism, or excess growth hormones.

Causes: Official cause is unknown but it is believed that it happens during the developmental process.

Treatment: Stripping can be done on affected tooth, removing about 0.5mm from each side of a tooth.  The dental practitioner

may also trim the entire tooth. 

Microdontia/ Macrodontia [K00.2]

Anodontia [K00.0]

Anodontia is an extremely rare genetic disorder defined as the absence of all teeth. The location of the faulty gene is not yet known. Anodontia, is usually part of a syndrome and seldom occurs alone.

Rare but more common than complete anodontia are hypodontia and oligodontia. Hypodontia is the absence of 1 to 6 teeth. Oligodontia is when more than six teeth are missing.
