【摘要】 目的:探讨碧兰麻用于麻醉牙髓时的方法及效果。方法:急性牙髓炎患牙94颗,慢性牙髓炎患牙68颗,作唇(颊)侧根尖区黏膜下浸润麻醉(单侧麻醉),观察麻醉效果;对上、下磨牙、下前磨牙设颊、舌侧麻醉组(双侧麻醉组)与上述同名牙的单侧麻醉组对照。所得结果用四格表χ2检验。结果:162颗牙髓炎患牙,单侧麻醉显效率为72.8%。麻醉效果与牙髓的急、慢性炎症状态无显著关系(P>0.05)。下磨牙作双侧麻醉,效果明显优于单侧麻醉(P<0.05)。结论:牙髓炎患牙作牙髓摘除术时,用碧兰麻作单侧麻醉具有良好的效果,建议对下磨牙作双侧麻醉。更多还原

【Abstract】 PURPOSE:To explore the application and the anaesthetic effect of primacaine in anaesthetizing the pulp. METHODS :162 teeth of pulpitis underwent submucous infiltration anaesthesia via the labial or buccal side (single side anaesthesia).There were 94 teeth of acute pulpitis and 68 teeth of chronic pulpitis among them.Anaesthesia effect were observed.Maxillary , mandibular molars and mandibular premolar were respectively divided into two groups, one underwent submucous infiltration anaesthesia via the labial or buccal and lingual sides (double sides anaesthesia), the other underwent single side anaesthesia.The data was analysed with ÷2 test. RESULTS:The effective rate of single side anaesthesia was 72.8%, There was no significant difference between acute and chronic pulpitis(P>0.05).For mandibular molar,the effect of double side anaesthesia was better than the single side anaesthesia (P<0.05). CONCLUSIONS :Primacaine had a good anaesthesia effect when the teeth of pulpitis underwent pulpectomy. In order to get perfect anaesthetic effect , the double side anaethesia for the mandibular molar was suggested.更多还原
