BACKGROUND

The mandible has a poorly permeable and dance outer cortical layer, and the use of regional anesthesia is usually required. Of interest is hydrochloric acid (E507) plays an extremely important role in the composition as an auxiliary substance. The acidic environment contributes to the fact that articaine and epinephrine, containing amino groups in their composition, exist in the form of ammonium salts. This significantly increases the solubility of the above pharmaceutical substances in the aquatic environment.

OBJECTIVE

To evaluate the clinical experience of using anatomically guieded mandibular anesthesia by Egorov P.M. in the treatment of mandibular teeth.

MATERIAL AND METHODS

To evaluate the effectiveness of an individual approach to conduction anesthesia, a comparative assessment of the indicators of electronic pulp test of the first molar in the lower jaw was carried out in the treatment of patients aged 30—55 years of both sexes (40 people) for exacerbation of chronic periodontitis (K046 periapical abscess with a cavity). The average values of the norm are taken to the electrical excitability of the pulp from 2 μA to 6 μA. As preparations, a 4% articaine-containing local anesthetic (LA) 1:200 000 №1 (Ultracaine D-S) and №2 (Articaine INIBSA) with hydrochloric acid as a preservative was used.

RESULTS

Despite the presence of an apical inflammatory process, in the case of the use LA №2, there was a more effective change in EDI indicators, indicating the onset of clinically significant pain relief. Because the optimal value of pulpal anesthesia is conventionally considered to be 90 μA, the advantage of LA №2 is obvious. The remaining high rate by the 40th minute of the study indicates the clinical significance of the preservative E507.

CONCLUSIONS

The anatomical rationale for conduction anesthesia in dentistry allows an individual approach to patients with different skull morphometry; the clinical efficacy of using a local anesthetic with preservative E507 in the treatment of teeth for inflammatory diseases in combination with a personalized method of conductive anesthesia was determine.
