Clinical and radiographic evaluation of zinc oxide eugenol and metapex in root canal treatment of primary teeth

J Indian Soc Pedod Prev Dent. 2011 Jul-Sep;29(3):222-8. doi: 10.4103/0970-4388.85829.


Objectives: The aim of this study was to evaluate clinically and radiographically zinc oxide eugenol (ZOE) and Metapex as root canal filling material in primary teeth.

Materials and methods: Forty-two necrotic primary teeth in two groups of children in the age group of 4-7 years were obturated with ZOE and Metapex and were followed up clinically and radiographically for a period of 6 months postoperatively.

Results: The overall success rates of ZOE and Metapex were 85.71% and 90.48%, respectively.

Conclusion: Both ZOE and Metapex gave encouraging results; however, Metapex can be used more safely whenever there is a doubt about the patient's return for follow-up.
