背景:在下颌侧切牙中发现4%阿替卡因与1:100,000肾上腺素的组合唇浸润(1.8mL)加舌浸润(1.8mL)优于1.8mL相同溶液的唇浸润。然而,不知道音量或位置是否有最大的影响。因此,这个前景的目的,随机交叉研究旨在确定在下颌侧切牙中,与使用1:100,000肾上腺素的4%阿替卡因的阴唇浸润(1.8mL)加舌侧浸润(1.8mL)相比,使用1:100,000肾上腺素的4%阿替卡因的阴唇浸润(1.8mL)的麻醉效果.
方法:一百名受试者随机接受两组注射,使用4%阿替卡因和1:100,000肾上腺素,在两个单独的预约中,包括1.8mL(总共3.6mL)的唇和舌浸润和1.8mL(总共3.6mL)的下颌侧切牙的两个唇浸润。使用电浆测试来确定麻醉成功(最高80/80读数)。对数据进行统计学分析。
结果:与两种唇浸润(74%)相比,唇和舌组合显示出明显更高的麻醉成功率(97%),并且从1分钟到58分钟具有明显更高的80/80s读数。
结论:在本临床研究的局限性内,与使用3.6mL阿替卡因的唇浸润相比,使用3.6mL体积的4%阿替卡因和1:100,000肾上腺素的组合唇+舌浸润显着增加了下颌侧切牙的牙髓麻醉成功率。因此,渗透的位置比体积更重要。
BACKGROUND: A combination labial infiltration (1.8 mL) plus
lingual infiltration (1.8 mL) of 4% articaine with 1:100,000 epinephrine in the mandibular lateral incisor was found superior to a labial infiltration of 1.8 mL of the same solution. However, it is not known whether the volume or the location had the greatest effect. Therefore, the purpose of this prospective, randomized crossover study was to determine the anesthetic efficacy of a labial infiltration of a 3.6 mL volume of 4% articaine with 1:100,000 epinephrine compared with labial infiltration (1.8 mL) plus
lingual infiltration (1.8 mL) of 4% articaine with 1:100,000 epinephrine in the mandibular lateral incisor.
METHODS: One hundred subjects randomly received 2 sets of injections, using 4% articaine with 1:100,000 epinephrine, consisting of labial and
lingual infiltrations of 1.8 mL (3.6 mL total) and 2 labial infiltrations of 1.8 mL (3.6 mL total) of the mandibular lateral incisor in 2 separate appointments. Electric pulp testing was used to determine anesthetic success (highest 80/80 reading). The data were analyzed statistically.
RESULTS: The labial and
lingual combination exhibited a significantly higher anesthetic success rate (97%) when compared with the 2 labial infiltrations (74%) and had significantly higher 80/80s readings from 1 minute to 58 minutes.
CONCLUSIONS: Within the limitations of this clinical study, a combination labial plus
lingual infiltration using a 3.6-mL volume of 4% articaine with 1:100,000 epinephrine significantly increased pulpal anesthetic success for the mandibular lateral incisor when compared with a labial infiltration using a 3.6-mL volume of articaine. Therefore, location of the infiltrations was more important than volume.
