摘要
目的评定口腔无痛麻醉仪在年轻恒牙牙髓病治疗中的应用效果。方法采用单纯随机法,将56例年轻恒牙急性牙髓炎或慢性牙髓炎患者随机分为试验组和对照组各28例,试验组采用无痛麻醉仪注射碧兰麻,对照组采用传统手推针管式注射器注射2%利多卡因作局部麻醉,然后进行开髓操作,完成后由患者评定疼痛程度(视觉模拟评分,VAS值)、恐惧程度,医生评定麻醉效果。结果与对照组比较,试验组在疼痛程度、恐惧程度方面较好,其差异均有统计学意义(P<0.05),而麻醉效果两组间差异无统计学意义(P>0.05)。结论口腔无痛麻醉仪能有效减轻注射疼痛,降低少年儿童的牙科恐惧感。
Objective To investigate the effect of local anesthetic delivery system in the treatment ofpulpitis of immature permanent teeth. Methods In a randomized, double-blind clinical trial, 46 patients with pulpitis of im-mature permanent teeth were randomly allocated to two groups, with 28 patients in each group. The study group was injected with Primacaine by local anesthetic delivery system, and the control group was given 2% Lidocaine with the conventional injector. Then pulp opening was performed in the two groups. The pain degree （visual analogue scale, VAS） and fear degree was evaluated by patients after injection. The effect of anesthesia was evaluated by doctors. Results The pain degree and fear degree were found to be significantly better in the study group than the control group （P〈0.05）. There was no statistically significant difference in anesthetic effect between the two groups （P〉0.05）. Condusion The local anesthetic delivery system can reduce the pain and young children＇s dental fear.
