Survival Function of Clinical and Radiographic Success of Three Obturating Materials in Primary Teeth at 3, 6 and 9 Months Periodic Intervals - A Randomized Controlled Clinical Trial.

Abstract

The study aims to assess clinically and radiographically the success of zinc oxide eugenol, metapex, and endoflas as root canal obturating materials in primary teeth over 3, 6, and 9 months of time intervals. The randomized controlled trial was performed in 60 primary molars of 36 children aged between 4 and 9 years. Permanent restorations were given and stainless steel crowns were placed for the treated tooth. Comparing the survival proportion between the three groups was done using the Wilcoxon (Gehans) statistical test. The clinical survival variable showed 100% survival proportion for zinc oxide eugenol and endoflas, while for metapex it was 69% at the end of 9 months. The radiographical survival proportion was 100% for zinc oxide eugenol, followed by endoflas at 92% and 58% for metapex group.
