Comparison of Iranian Propolis and Formocresol in Pulpotomized Primary Molars: A Preliminary study

The aim of this study was to evaluate the clinical and radiographic outcomes of Propolis in pulpotomized primary molars in comparison with Formocresol. In this clinical trial, 26 lower second primary molars of thirteen children were treated by conventional pulpotomy technique. The teeth were randomly assigned to Propolis (experimental) and Formocresol (control) groups in each patient (split mouth).Following removal of the coronal pulp and haemostasis, the pulp stumps were covered with Propolis in the experimental group and then resin-modified glass ionomer cement was applied over the gel. In the control group, Formocresol (FC) was placed with a cotton pellet over the pulp stumps and then reinforced zinc oxide eugenol cement was applied in pulp chamber. Finally, the teeth of both groups were restored with stainless steel crowns the data were analyzed using Mc Nemar test (α=0.05). All patients developed failure clinically within two months of treatment. The radiographic evaluation revealed furcation involvement and extensive radicular radiolucency in molars treated with Propolis. The present study showed the failure of Propolis in pulpotomized primary molars; therefore, it could not be used as a safe medicament for pulpotomy in human primary molars.
