摘要
目的探讨不同材料根尖诱导成形术治疗年轻恒牙感染根管的临床疗效。方法 90颗(85例患者)年轻恒牙根管感染行根尖诱导成形术治疗,随机均分为两组:A组采用Vitapex糊剂,B组采用氢氧化钙糊剂。随访24个月,比较两组疗效。结果 A组患者术后3、12、24个月的总有效率为88.9%、93.3%、86.7%,均分别高于B组的66.7%、73.3%、64.4%(P<0.05)。A组术后根尖闭合时间早于B组[(12.2±1.5)个月vs.(16.7±1.8)个月](P<0.05)。结论采用Vitapex糊剂行根尖诱导成形术治疗年轻恒牙感染根管的临床疗效优于氢氧化钙糊剂,可减少患者就诊次数及治疗周期。
Objective To observe the clinical efficacy of apexification with different materials in treating infected young permament teeth. Methods A total of 90 infected young permament tooth（85 patients） underwent apexification was randomly assigned into two groups of A （apexification with Vitapex paste） and B（apexification with calcium hydroxide paste） with 45 teeth each. The clinical efficacy was compared between two groups. Results The total effectiveness rates of 3, 12 and 24 months in group A were 88. 9%, 93.3% and 86.7%, respectively, which were significantly higher than 66.7%,66. 7% and 73.3% in group B（P〈0. 05）. The time for root apex closure was shorter in group A than that in group B[（12. 2±1.5） months vs. （16. 7±1.8） months] （P〈0. 05）. Conclusion The apexification with Vitapex paste has better therapeutic outcomes than that with calcium hydroxide paste in treating infected young permament teeth with reduced cycle and frequency of treatment.
