Description
Cysts can also occur in the oral cavity, with one cause of tooth. The definition of a cyst is a pathological cavity containing a liquid, semi liquid or gas that is limited by the epithelium or connective tissue. Periapical cyst is a cyst that most commonly occur in the oral cavity.

Periapical cysts belong in odontogenic cysts. Odontogenic cyst itself has a meaning that is caused by dental cysts, either because of inflammation in the teeth or due to malformations (abnormal formation) during tooth development.

While the periapical cyst is a cyst that forms on the tooth root tip tissue pulpanya (nerves) is dead, which is a continuation of inflammation in dental pulp tissue (pulpitis). Diagnosis of periapical cysts can be determined through dental x-ray and histological examination.

Cause
Periapical cyst is a further progression of infection due to dental caries (cavities). If untreated cavities allowed to continue, it will cause inflammation in dental pulp tissue (pulpitis) and death occurs in the tooth nerve. After the tooth nonvital (dead) over time will be able to form cysts in the periapical tooth root tip.

Symptom
Periapical cysts generally do not cause complaints or pain, except in case of infection in the cyst (secondary infection).

Treatment
There are several treatment options in these cysts, among others:

1. Endodontic treatment (treatment of dental nerve)
If the cyst is formed is not too big or worse yet, can still be performed endodontic treatment. If the treatment is done, it is necessary dental x-rays periodically to check the healing of the cyst.

2. Cyst retrieval
This treatment is most often done to deal with periapical cyst, because if the endodontic treatment is not necessarily successful healing. Taking these cysts sometimes also accompanied by making the teeth involved.
