Dexamethasone plus lidocaine Local closed to cure Inter-appointment?pain and To prevent swelling

目的通过观察分析常规药物治疗联合地塞米松加利多卡因局部封闭治疗对疼痛与肿胀的缓解作用,探讨治疗根管治疗期间急症方法。方法选取该院2011年1月—2012年1月进行根管预备后发生急性根尖疼痛的80例患牙,随机均分为实验组与对照组,对照组40例患牙给予头孢氨苄片和甲硝唑片口服;实验组40例患牙给予头孢氨苄片和甲硝唑片口服,并行根尖区地塞米松加利多卡因局部封闭治疗。对比两组间疼痛缓解率和根尖区肿胀发生率进行统计学处理。结果实验组疼痛缓解率(75%)高于对照组(35%),实验组患者肿胀发生率(10%)低于对照组(30%)。两组患牙治疗效果差异具有统计学意义(P<0.05)。结论地塞米松加利多卡因局部封闭可以缓解根管预备后的疼痛,降低发展成根尖周脓肿的发生率,值得临床推广应用。

Comparison between the two groups of pain response rate and the incidence of apical swelling, and statistical analysis. Results Experimental pain remission rate （75%） than the control group （35%）,the incidence of swelling in the experimental group patients （10%）, lower than the control group （30%）.Two groups were comparable with dental treatment ef-fect differences （P〈0.05）. Conclusion Dexamethasone Gary lidocaine local closed can relieve pain after root canal preparation,re-duce the incidence of development into periapical abscess, worthy of clinical popularization and application.
