目的比较牙周韧带浸润麻醉与下牙槽神经阻滞麻醉用于下颌磨牙不可复性牙髓炎开髓治疗的麻醉效果。方法下颌磨牙不可复性牙髓炎患者120例随机均分为三组,A、B组分别采用甲哌卡因、阿替卡因行牙周韧带浸润麻醉;C组采用利多卡因行下牙槽神经阻滞。比较三组的麻醉效果。结果 A、B、C组患者麻醉均满意,VAS疼痛评分3分以下者分别为38例(95.0%)、39例(97.5%)、38例(95.0%),差异无统计学意义(P>0.05)。结论在下颌磨牙不可复性牙髓炎开髓治疗中,甲哌卡因或阿替卡因行牙周韧带浸润麻醉均可取得与利多卡因行下牙槽神经阻滞一样的良好麻醉效果。
Objective To compare the anesthetic effects of periodontal ligament infiltration anesthesia and inferior alveolar nerve block anesthesia for the treatment of mandibular molars with irreversible pulpitis. Methods One hundred and twenty cases of mandibular molar non-reflex pulpitis were randomly divided into three groups: group A and group B were treated with mepivacaine and periodontal ligament embolization with articaine; group C with lidocaine Slot nerve block. Compare the anesthetic effects of the three groups. Results Patients in groups A, B and C were satisfied with anesthesia. There were 38 cases (95.0%), 39 cases (97.5%) and 38 cases (95.0%) with VAS pain scores less than 3 points respectively, with no significant difference (P> 0.05). Conclusions In the treatment of mandibular molars with refractory pulpitis, anesthesia with periodontal ligament infusion of mepivacaine or articaine can achieve the same good anesthetic effect as that with lidocaine.
