[摘要]目的：观察氢氧化钙糊剂联合牙髓血运重建术治疗年轻恒牙牙髓坏死的效果。方法：选取2020年3月-2021年12月笔者医院收治的年轻恒牙牙髓炎坏死患者94例，按随机数字表法分为对照组(给予三联抗生素糊剂联合牙髓血运重建术治疗)和观察组(给予氢氧化钙糊剂联合牙髓血运重建术治疗)，各47例。对比两组临床症状评分、临床疗效、疼痛情况、牙根长度、根管壁厚度、满意度评分及不良反应。结果：治疗后，观察组牙龈肿胀、叩痛、牙齿松动评分均低于对照组(均P<0.05)。观察组总有效率(97.87% vs.85.11%)高于对照组(P<0.05)。观察组治疗后6、12个月视觉模拟疼痛评分(VAS)均低于对照组(P<0.05)。观察组牙根长度、根管壁厚度均高于对照组(均P<0.05)。观察组牙齿色泽、咬合度及整体美观性满意度评分均高于对照组(均P<0.05)；两组咀嚼功能满意度评分及治疗后不良反应发生率对比，差异均无统计学意义(均P>0.05)。结论：年轻恒牙牙髓坏死用氢氧化钙糊剂联合牙髓血运重建术治疗可改善临床症状，提高临床疗效，降低术后疼痛，促进牙根发育，提高患者满意度，且安全可靠。
