A Clinical and Radiographic Study of Four Different Root Canal Filling Materials in Primary Molars—An In Vivo Study

Abstract

Introduction Pulpectomy helps in preserving a pulpally involved primary tooth by eliminating bacteria and their products and ensures hermetic seal of the root canals, so that the primary teeth can complete their function until normal exfoliation. For the success of endodontic treatment in primary teeth, the resorption of obturating material plays a vital role. The materials used for obturation in this study included zinc oxide propolis (ZOP) as a new paste, Endoflas, Metapex, and zinc oxide eugenol (ZOE).Objective To evaluate the success rate of pulpectomy of primary molars using four different root canal filling materials: ZOP as a new paste, Endoflas, Metapex, and ZOE.Materials and Methods A total of 48 primary molars were divided into four equal groups of 12 molars according to the type of root canal filling paste, that is, ZOE, Endoflas, ZOP, and Metapex.Results When Tukey’s test was applied, out of the four materials, ZOP was the most significant material as its p-value was < 0.05, whereas other materials showed nonsignificant results as their p-value was > 0.05.Conclusion Among the four groups, ZOP showed greater clinical success and its resorbability was similar to that of root.
