The aim of the study was to prove the anatomical and clinical effectiveness of the modified anesthesia of mental nerve. The effectiveness of conductive anesthesia near the mental foramen was objectively evaluated using the electric pulp test (EPT) in 100 volunteers of both sexes, aged 35-43 years. Wet anterior mandible preparations obtained from 350 cadavers aged 18-74 years were also studied. EPT value after local mental anesthesia conducted according to Malamed C. using 4% articain solution of local anesthetic with vasoconstrictor concentration of 1:200.000 after 2 minutes was 93±0.82 mA, after 4 minutes - 188±1.26 mA. Yield variability indicators of intraosseous mental nerve anesthesia was slightly higher varying from 94.11 mA to 96.61 mA after 2 minutes and from 197.4 to 199.92 mA after 4 minutes survey. The study showed the efficiency and predictability of intraosseous anesthesia of the mental nerve.

The article presents the results of the cardiovascular changes assessment using electrocardiography (ECG) monitoring during local anesthesia in GP dentists. Selective ECG monitoring was carried out in 60 dentists aged 25-55 years (1 group - 25-34 y.o.; 2 group - 35-44 y.o.; 3 group - 45-55 y.o.) by means of portable «Valens» system. The study of stress index or the index of regulatory systems tension (IT) was conducted for 6 hours in the first day half within 1 working day. IT from 50 to 150 relative units was considered normal. In the first group IT peak was observed at the time of expectation of clinically relevant anesthesia in upper and lower jaw, while in the second and third groups it was associated with pain reaction in the course of treatment despite of clinical signs of anesthesia in the maxilla (IT=20±5.3 and 231±1.4, correspondingly) and mandible (IT=213±2.7 and 223±2.6, correspondingly). In all groups greater IT correlated more with mandible anesthesia events.

Цель исследования-изучить эффективность и безопасность проводниковой анестезии на нижней челюсти по П.М. Егорову и по модифицированной методике Дж. Гоу-Гейтса. Материал и методы. В исследование вошли 92 пациента, разделенные на группы в зависимости от метода анестезии: по П.М. Егорову (45 пациентов) или по методу Дж. Гоу-Гейтса в модификации С.А. Рабиновича и О.Н. Московца (47 пациентов). Результаты. При проведении блокады нижнечелюстного нерва по Дж. Гоу-Гейтсу в модификации С.А. Рабиновича и О.Н. Московца частота местных осложнений составила всего 1,9% при эффективности обезболивания 98%. Заключение. При хирургических стоматологических вмешательствах и лечении воспалительных заболеваний на нижней челюсти более эффективным и безопасным является модифицированный способ блокады нижнечелюстного нерва по Дж. Гоу-Гейтсу.
