Abstract

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.

摘要

本研究的目的是证明改良颏神经麻醉的解剖学和临床有效性。使用牙髓电活力测试（EPT）对100名年龄在35 - 43岁的男女志愿者进行客观评估，以确定颏孔附近传导麻醉的有效性。还对从350具年龄在18 - 74岁的尸体上获取的湿润下颌前部标本进行了研究。按照马拉梅德C法，使用含1:200,000血管收缩剂浓度的4%阿替卡因局部麻醉溶液进行局部颏神经麻醉后，2分钟时EPT值为93±0.82毫安，4分钟时为188±1.26毫安。骨内颏神经麻醉的有效率变异性指标略高，2分钟后的测量值在94.11毫安至96.61毫安之间，4分钟后的测量值在197.4毫安至199.92毫安之间。该研究表明了颏神经骨内麻醉的有效性和可预测性。
