Clinical and Radiographic Evaluation of Pulpectomy in Primary Molars with a Modified Paste, Zinc Oxide-Eugenol, and Vitapex
Objectives: The aim of this study was to compare the clinical success rates and radiographic resorption rates of a modified primary root canal filling (MPRCF group, ingredients: zinc oxide–eugenol [ZOE], iodoform, calcium hydroxide) to that of ZOE and Vitapex in pulpectomised primary molars.
Methods: One hundred and sixty primary molars from 155 children (average age 5.88 ± 1.27 years) underwent two-visit pulpectomy using one of the three materials via block randomisation. Two investigators not otherwise involved in the study assessed the clinical and radiographic findings at 6, 12 and 18 months.
Results: At 6 and 12 months, the MPRCF and ZOE success rates were 100% both in clinical and radiographic evaluation. The Vitapex group showed clinical success rate and radiographic success rate of 100% and 94.5% at 6 months, and 80.4% and 60.7% at 12 months. The 18-month clinical success rates of the MPRCF, ZOE and Vitapex were 96.2%, 92.2% and 71.4% and radiographic success rates were 92.5%, 88.2% and 53.6%, respectively. There was a statistically significant difference in the success rates between MPRCF and Vitapex at 12 and 18 months and no significant differences between MPRCF and ZOE. More MPRCF were resorbed at same rate with roots than ZOE and Vitapex.
Conclusions: A mixture of ZOE, iodoform and calcium hydroxide can be considered an effective root canal filling material in pulp involved primary teeth.
