牙周膜注射与根尖浸润用于儿童第一恒磨牙麻醉的效果评价

The Evaluation of Applying Periodontal Membrane Injection and Apical Area Infiltration to Children's First Permanent Molar Anesthesia

目的:比较远中牙周膜注射与根尖区局部浸润在儿童第一恒磨牙牙髓病治疗中的麻醉,观察患儿在注射中的疼痛情况及麻醉效果。方法:选择100例因第一恒磨牙牙髓病需要治疗的6~12岁患儿,用计算机随机数字法随机分为两组,分别采用远中牙周膜注射与根尖区局部浸润进行麻醉,采用疼痛视觉模拟量表测定患儿在注射中的疼痛值,采用Venham临床焦虑及合作行为级别评定量表评价患儿在治疗中的焦虑程度和临床表现,并进行统计学分析。结果:试验组患儿在注射中的疼痛得分明显低于对照组,在治疗中临床焦虑及合作级别评分稍低于对照组,差异均有统计学意义。结论:在6~12岁儿童第一恒磨牙牙髓病治疗过程中,应用远中牙周膜注射进行局部麻醉效果好、创伤小,是一种值得推广使用的麻醉方法。

Objective:To compare the effects of periodontal membrane injection and apical area infiltration for the treatment of children pulp disease of the first permanent molar and to observe the patients'sense of pain during injection.Methods:A total of 100 children six-to twelve-year-old suffering from pulp disease of the first permanent molar were included in the study and randomly divided into two groups with computerized random number method,respectively using distal periodontal membrane injection(the experimental group)and apical area infiltration anesthesia(the control group).Pain visual analog scale was used to determine pain values during injection,Venham rating scale of clinical anxiety and level of cooperative behavior was used to evaluate children anxiety levels and behaviors during treatment,statistical analysis were performed.Results:Pain values of the experimental group during periodontal membrane injection were significantly lower than the control group,meanwhile scores of clinical anxiety and levels of cooperation in the experimental group were slightly lower than the control group,and the differences were statistically significant.Conclusion:Distal periodontal membrane injection,when compared with apical area infiltration anesthesia,produces less pain,has better accessibility,exhibits better anesthetic effect and causes less trauma during treatment of the first permanent molar pulp disease in children 6-to 12-year-old.
