VITAL EXTIRPATION Advantages of vital extirpation:
• absence of the toxic operating of arsenic;
• treatment is carried out in one session;
• manipulations in a tooth are not sickly.
Disadvantages of vital extirpation :• a risk of complications is during conducting of anesthesia
• bleeding from a channel
• origin of pain at bitibg as a result of formation of hematoma in a periapical
• development of remaining root pulpitis

Indications of Vital Extirpation o all total forms of pulpitiso pulpits which treated oneself biological methods, but there was complication;
o at localization of carious cavity in a vestibular area or in cement of root of tooth;
o intact teeth which it is necessary depulpation after orthopaedic
o at treatment of teeth under bridge prosthetic appliances;
o general paradontitis especially before surgical interference.

Contraindication of Vital Extirpation • unbearable to apply anesthetics
• grave somatic condition of patient, declining years;
• for patients with the broken psyche;
• in the last and in the first weeks of pregnancy (if there is a threat of abortion)

Methods of vital extirpation • hygiene of cavity of mouth
• anaesthetizing
• Rubber dum
• a carious cavity is prepared and wash
• perforation the vault of cavity the sterile spherical drill and fissured extend it
• by antiseptic solutions wash blood, tailings of pulp
• extend the channels of roots;
• by pulpextractor (files) extraction the pulp.

DEVITALIZATION
Arsenic acid (As2O3) is one of strong poisons
Arsenic acid (anhydride) is used as paste.
Such components enter in composition of arsenic paste:
- antiseptics;
- anesthetic matters (cocaine and other);
- arsenic acid;
- astringent facilities
