Comparison of zinc oxide and eugenol, and Vitapex for root canal treatment of necrotic primary teeth.

摘要

Summary. Objectives. The aims of this study were to evaluate iodoform base materials for root canal treatment of necrotic primary teeth, and to compare them with traditionally used zinc oxide and eugenol (ZOE). Sample and Methods. Zinc oxide and eugenol and Vitapex (a premixed calcium hydroxide and iodoform paste) were compared for root canal treatment in 52 necrotic primary teeth in two groups of children with a mean age of 5 years and 8.4 months. All the patients were followed-up clinically and radiographically 3 months and 10-16 months postoperatively. Results. The overall success rates of Vitapex and ZOE were 100% and 78.5%, respectively. Using Fisher's Exact Test, the difference was statistically significant (P < 0.05). Conclusion. Both ZOE and Vitapex gave encouraging results. Vitapex, however, can be used more safely whenever there is a doubt about the patient's return for follow-up.
