Purpose:~The purpose of this study was to evaluate the clinical and radiographic effects of placement of reinforced zinc oxide eugenol (ZOE) base directly over the amputated pulp stumps in pulpotomized primary molars, and to compare the effects of this technique to ferric sulphate (FS) agent in pulpotomized primary teeth.~Methods:~A sample of 65 children with bilateral deep carious mandibular primary molars who attended the pediatric dental clinics, at Jordan University of Science and Technology (JUST) were selected for this prospective randomized, single blinded; split-mouth clinical trial. The teeth were randomly divided into 2 treatment groups: in the ZOE group (n=65 teeth) hemostasis was achieved by a dry cotton pellet, then the chamber was filled with zinc oxide eugenol (ZOE) directly over the pulp on one side. In the FS group (n=65 teeth) hemostasis was achieved by a wet cotton pellet, ferric sulphate (FS) was applied on the pulp, then the chamber was filled with (ZOE) on the contralateral side. All teeth were restored with prefabricated stainless steel crowns (SSC). Patients were recalled for evaluation clinically after 1month, then clinically and radiographically after 3, 6, 12 and 24 months. Two experienced and calibrated pediatric dentists who were not involved in the investigation blindly assessed the radiographs.

Included were 65 children using a split-mouth design, (130 teeth). All teeth were then restored with prefabricated stainless steel crowns (SSC). Patients were recalled for clinical and radiographical evaluation after 3, 6, 12 and 24 months.
