Methods.: 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® 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. Results.: Both groups showed 100% and 96% clinical success at 6 and 12 months, respectively. At 6 months, radiographic success of 3Mix and Vitapex® was 84% and 80%, respectively, and at 12 months, radiographic success of 3Mix and Vitapex® 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). Conclusion.: 3Mix and Vitapex® can be used as a root canal treatment agent in pulpally involved primary teeth. © 2010 The Authors.
