Abstract
Purpose: To compare the clinical and radiographic success rates of indirect pulp treatment (IPT) in primary molars using mineral trioxide aggregate (MTA) with and without two percent chlorhexidine gluconate (CHX).
Methods: A blinded, randomized, controlled clinical
trial was performed in a split-mouth desi gn. Eighty primary molars in 40 subjects from four to eight years of age were randomly allocated so that each subject had one tooth treated with MTA and CHX and the other tooth treated with MTA alone. Study teeth had deep caries without signs and symptoms
of pulpal inflammation or necrosis. All teeth were restored with stainless steel crowns. Follow-up was done at 12 months to evaluate the teeth clinically and radiographically.
Results: At the follow-up, one tooth from each group had failed. Upon the clinical and radiographic
evaluations, the overall success rate for both groups was 97 percent. No statistically significant difference was found in the success rate between the two groups.
Conclusions: IPT in primary molars using MTA with or without CHX demonstrated satisfactory clinical and radiographic
outcomes in a period of 12 months.
