甲哌卡因在不可逆性牙髓炎治疗中的应用

The Clinical Efficacy of Mepivacaine in the Treatment of Irreversible Pulpitis

目的评价2%甲哌卡因在不可逆性牙髓炎治疗中的疗效。方法将396例不可逆性牙髓炎患者以2%甲哌卡因行粘膜下浸润麻醉,观察麻醉效果。结果 283例磨牙行开髓引流术或牙髓失活术,其余113例患者行一次性拔髓后行根管预备术。上下颌牙麻醉优良率分别是94.71%和83.09%,经统计学分析构成比有显著性差异(P<0.01);磨牙、前磨牙和前牙麻醉优良率分别是84.45%、98.85%和100%,经统计学分析构成比有显著性差异(P<0.01)。结论甲哌卡因操作简单,显效时间快维持时间长且副作用小,在牙髓治疗术中可取得良好的麻醉效果。

Objective The study was designed to compare the eppicacy of infiltrated anesthesia with mepivacaine for treatment of irreversible pulpitis. Methods All 396 outpatients who suffered from irreversible pulpitis received local infiltration with 2% mepivacaine.The anesthetic effect was observed. Results 283 molar teeth received odontotrypy or pulp devitalization surgery, and other 113 patients received root canal preparation. The anesthesia excellent rate of upper and lower dental was 94.71% and 83.09% respectively （P 〈0.01）; the anesthesia excellent rate of molars, premolars and anterior teeth was 84.45%, 98.85% and 100% respectively （P 〈0.01）. Conclusions Mepivacaine is effective and safe anesthetics in endodontic therapy.
