三种不同材料用于年轻恒牙根尖诱导的临床效果评价

Evaluation of clinical effects of three different materials for inductionon immature permanent teeth apexification

目的分析研究三种不同类型的糊剂对年轻恒牙根尖发育的影响。方法选取2015年9月至2016年9期间来我院门诊就诊的9~18岁根尖未闭合的患者60例,按照随机数字表法将患者分为比塔派克斯糊剂组、氢氧化钙糊剂组和三氧化聚合物组,所有患者治疗完成后每隔3个月进行复诊,由经过培训的口腔医生采用临床检查和X线片显示结果对患者的临床疗效进行分析。结果统计学分析结果显示氢氧化钙糊剂组,比塔派克斯糊剂组和三氧化聚合物组在疗效、诱导周期、术后咀嚼效能方面具有显著差异(P<0.05),且MTA组成功率均高于其他两组。结论三氧化聚合物具有良好的临床效果和较短的治疗周期,在年轻恒牙根尖诱导的治疗上具有显著优势,值得推广。

Objective To analyze the effect of three different paste materials on immature permanent teeth apexification.Methods 60 patients about 9～18 years old with the open apices teeth were randomly selected from the patients who came to our hospital between Sep. 2015 and Sep. 2016.The teeth were divided into three groups about the MTA group and the Vitapex group and the calcium hydroxide cataplasm group.The case were followed up at regular intervals of every 3 months after treatment. The clinical ef？ cacy was analyzed by well trained dentist by the method of clinical examinations and x-ray.Results The results of statistical analysis showed that there were signi？ cant differences （P〈0.05） in the eficacy, induction period and postoperative masticatory eficiency between the calcium hydroxide cataplasm group ,the Vitapex group, and MTA group.The success rate of MTA group was higher than the other two groups.Conclusion There were better clinical effect and shorter treatment period in MTA, and had apparent advantage in treatment of immature permanent teeth apexiication ,it has worth spreading.
