目的 研究石辛含片治疗胃火牙痛（智牙冠周炎）的临床疗效。方法 采用随机对照试验,将符合胃火牙痛（智牙冠周炎）的初诊患者80例,随机分成试验组和对照组,每组40例。就诊当日先行常规局部冠周冲洗,试验组含服石辛含片0.6g×2,4次/天,对照组采用碘甘油上药。治疗10min后,使用视觉模拟评分（VAS）标尺法记录2组患者的镇痛效果,治疗后第3、7天应用疼痛计分法记录患者的炎性控制情况,并对2种治疗方法的效果进行综合评价。结果 治疗10min后,试验组37.5%的患者疼痛基本消失,而对照组不明显,治疗后第3、7天,试验组分别有90.0%和92.5%的患者疼痛消失,对照组分别有57.5%和87.5%的患者疼痛消失。综合治疗后3d,试验组和对照组的显效率分别为60.0%和42.5%,差异有统计学意义（P〈0.05）,治疗后7d,试验组和对照组的总有效率分别为95.0%和90.0%,差异有统计学意义（P〈0.05）。.结论 石辛含片对治疗胃火牙痛（智牙冠周炎）有明显的消炎镇痛疗效。
