Abstract：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.
