The use of arsenic in the treatment of teeth began with the beginning of the 19th century to relieve pain.
Over time, the properties and principle of action of arsenicWere well studied, due to which a temporary filling with a low content of arsenic was created, which allowed to carry out dental treatment with subsequent preservation.
Arsenic in dentistry
In dentistry, arsenic is used forKilling of the dental nerve, which causes painful sensations in caries, pulpitis and other diseases of the teeth. Arsenic is not used in its pure form, but in the form of arsenic paste. The composition of this paste includes: arsenic anhydride necrotizing action, antiseptics for disrupting the pulp (camphor, carbol or thymol) and painkillers (ice medicine, novocaine or dicaine).
Externally, the paste is a bulb the size ofPin head. It is laid in a cleared canal in the pulp. Next, cover with a swab moistened with camphor or phenol, and fix a temporary seal. The time of action of arsenic on the nerve lasts from 2 to 7 days, depending on its amount contained in the paste. The time to remove the temporary filling is prescribed by the attending physician. Arsenic must be removed from the tooth at the appropriate time, otherwise complications may occur. After removing the temporary filling, a permanent seal is applied.
Is arsenic harmful?
The minimum arsenic content should not beHarm the body. However, the damage to health using arsenic in dental treatment is debatable. First, the effect of toxins on young children or the fetus of a pregnant woman has not been studied. In the event that arsenic paste is accidentally swallowed, the consequences are difficult to predict. Secondly, it is noticed that arsenic adversely affects the dentin of teeth, leading to their gradual destruction. However, there are situations in which the use of arsenic is justified, for example, with individual intolerance of analgesics.
To avoid complications from usingTemporary fillings, it must be remembered that in no case should be allowed to overexpose arsenic paste in the cavity of the tooth. This is fraught with blackening of the dentin, inflammation of the pulp or periodontal tissues, destruction of hard tooth tissues and even general poisoning of the body. Therefore, if after the expiry of the period you can not get to the doctor, you need to remove the temporary seal yourself or call the doctor on duty. After this, do not delay the visit to the dentist, since the dead nerve tissues that are removed during the installation of a permanent seal can also cause serious problems.
After installing arsenic paste on the tooth, the painPasses from the action of pain medication, which it contains. Then the toxin blocks the nerve and begins to destroy it. When the effect of anesthetic substances weakens, the tooth may become a little "whining" during the first 24 hours - this means that arsenic acts. However, if the pain intensifies and becomes unbearable, urgently consult a doctor.
