Paradontitis, commonly known as paradontosis.
Paradontosis can be caused by:

• avitaminosis
• smoking
• exesive consumption of alcohol
• parafunction, habitual gnashing of teeth
• hormonal disorders
• systemic dosorders (ex. g. diabetes)
• wrong diet
• many incorrect protetic fillings
• disorders in salivation

In most cases paradontosis is caused by bacteria and scale gathering on teeth. They are a result of insufficient oral hygiene. Bacteria might penetrate into operculum (area between the edge of gingiva and the tooth tissue)

An exposed neck of a tooth and gingival inflamation are the first signs of paradontosis.
In time the affected tooth loses parts of its bone and as a result teeth become lose.
Gingival bleeding might appear in severe cases.

Treatment of “paradontosis” consists of a number of steps:

• initial treatment – hygienic prcedures
• proper treatment (periodontal surgery procedures, antibiotics)
• supporting treatment
