Rare dental intervention without pain. And this is the most urgent problem in today's dentistry. The technique of local anesthesia began to be used more than a century ago. At the end of the 18th century, cocaine was used for this purpose, and since 1906 they have introduced novocaine. Of course, it was not very effective, but the force of unpleasant sensations reduced significantly.
It was the low efficiency that made the search continue. So there was lidocaine. He was much stronger, but he did not satisfy practicing doctors, because complete anesthesia was still impossible to achieve. On novocaine there were periodic allergic reactions, and lidocaine proved to be more toxic than the predecessor.
In 1976, a new drug appeared - ultracaine. In dentistry, it was a breakthrough. Anesthetic from the amide group has surpassed, as it turned out, and novocaine( six times), and lidocaine( twice).In addition, it is less toxic and able to penetrate into bone and connective tissues without disturbing the work of the heart.
Ultracaine in dentistry has fastened and fastened. Thanks to the high degree of purification of this anesthetic, it became possible to abandon the antibacterial preservatives that cause such frequent allergic reactions.
In 1995, the German company Hoechst proposed the use of advanced ultracaine in dentistry. The price was slightly higher, but the improved quality allowed the use of anesthetic in daily practice, and very effectively.
A group of young dentists observed the effects of ultracaine in the treatment of patients( used ultra-kin DS-forte).Of the 1275 patients, 647 had a carious process, 389 had pulpitis, and 239 had apical periodontitis. The age of patients is 18-50 years.
Patients with contraindications-tachycardia, narrow-angle glaucoma, tachyarrhythmia, bronchial asthma, para- group allergy, were excluded.
The efficacy of anesthesia was assessed clinically. During anesthesia, analgesia occurred two to three minutes after the injection, anesthesia of infiltration anesthesia occurred more rapidly, 30-60 seconds later, and with subperiosteal anesthesia, 20 seconds after the injection of ultracaine. After 30 minutes, the strengths of the anesthetic were the same as the initial ones. The sensitivity was restored after 180-300 minutes( depending on the type of anesthesia).Side effects of any of the observed patients were not noted. That is why ultracaine in dentistry reviews received the most approving, both from patients and doctors themselves.
The positive qualities of the drug are due to very low fat solubility( in lidocaine, for example, it is 2.5 times higher) and excellent binding to proteins, which affects the duration and strength of anesthesia. From the body, ultracaine is excreted faster than previous anesthetics. With submucosal administration, the approximate half-life is approximately 22 minutes. As for the effect on the liver, unlike lidocaine, procaine, bupivocaine, ultracaine( complex amides), degrading in the liver, ultracaine does not cause complications, so the drug can be recommended even in pregnancy.
