Arsenic in dentistry
In dentistry, arsenic is used for killing the dental nerve that causes pain during caries, pulp and other diseases of the teeth.Arsenic is not used in pure form but in the form of arsenous paste.The composition of this paste are: arsenic anhydride nekrotiruyuschego action, antiseptics obezorazhivaniya pulp (camphor, thymol, or carbol) and analgesics (ledokain, procaine or dicain).
Externally, the paste is a ball the size of a pinhead.It lay in the cleared channel in the pulp.Then cover with a swab soaked in camphor or phenol, and fixed a temporary filling.The effect of arsenic on the nerve lasts from 2 to 7 days, depending on its amount contained in the paste.Release tim
Harmful if arsenic?
Minimum arsenic should not harm the body.Nevertheless, personal injury using arsenic during dental treatment is debatable.Firstly, the impact of toxins on small children or the fetus of pregnant women has not been studied.If arsenious paste is accidentally swallowed, the impact is hard to predict.Secondly, it is noted that arsenic adversely affect the dentin of teeth, causing their gradual destruction.However, there are situations where the use of arsenic is justified, for example, an individual pain medication intolerance.
To avoid complications from the use of temporary fillings, it must be remembered that in any case should not be allowed overexposure arsenical paste in the cavity of the tooth.It is fraught with blackening dentin, pulp inflammation or periodontal tissue destruction of the hard tissues of the tooth, and even the general poisoning of the body.Therefore, if after the expiry get to the doctor failed, temporary filling must be removed by yourself or consult a doctor.Then do not delay your visit to the dentist, as the dead nerve tissue that is removed when you install a permanent seal, can also cause serious problems.
After installing the arsenical paste on a tooth, the pain goes away from the action of pain medication that it contains.Then, the toxin blocks the nerve and starts to destroy it.When the effect of anesthetic agents is weakened, the tooth can be a little "whine" during the first day - this means that arsenic acts.However, if the pain increases and becomes unbearable, seek medical attention immediately.
