The aim of this study was to compare the clinical and radiographic success of 3Mix and Vitapex((R)) for root canal treatment of pulpally involved primary molars.
Fifty teeth from 37 healthy children aged 3-8 years with pulpally involved primary molars needing root canal procedures were treated with 3Mix or Vitapex((R)) before restoration with stainless steel crowns. The research employed a prospective single-blinded randomized design. The subjects were followed up clinically and radiographically at 6 and 12 months, respectively. The outcome was compared using a Z-test with a significance level of 0.05.
Both groups showed 100% and 96% clinical success at 6 and 12 months, respectively. At 6 months, radiographic success of 3Mix and Vitapex((R)) was 84% and 80%, respectively, and at 12 months, radiographic success of 3Mix and Vitapex((R)) was 76% and 56%, respectively. Considering the radiographic findings at the end of 6 and 12 months, no statistically significant differences were found between the two groups (P = 0.356 and 0.068, respectively).
3Mix and Vitapex((R)) can be used as a root canal treatment agent in pulpally involved primary teeth.
本研究旨在比较 3Mix 和 Vitapex((R)) 在治疗牙髓病变的乳磨牙根管治疗中的临床和放射学疗效。
37 名 3-8 岁健康儿童的 50 颗牙髓病变的乳磨牙需要根管治疗，在使用不锈钢冠修复之前分别用 3Mix 或 Vitapex((R))进行治疗。本研究采用前瞻性单盲随机设计。分别在 6 个月和 12 个月时进行临床和放射学随访。采用 Z 检验比较两组的结果，显著性水平为 0.05。
两组在 6 个月和 12 个月时的临床成功率分别为 100%和 96%。在 6 个月时，3Mix 和 Vitapex((R))的放射学成功率分别为 84%和 80%，在 12 个月时，3Mix 和 Vitapex((R))的放射学成功率分别为 76%和 56%。考虑到 6 个月和 12 个月时的放射学结果，两组之间没有统计学上的显著差异（P = 0.356 和 0.068）。
3Mix 和 Vitapex((R))可作为牙髓病变乳磨牙的根管治疗剂。
