Clinical Evaluation of Mineral Trioxide Aggregate(MTA) as Immediate Permanent Direct Pulp Capping in Deciduous Teeth

Objective To evaluate the clinical effect of mineral trioxide aggregate(MTA) as immediate direct pulp capping in deciduous teeth.Methods Thirty-six deciduous teeth with deep caries or accidental pulp exposure with diameter ranging from 0.5-1.0 mm from patients between 4 and 8 years of age were randomly selected.The exposed pulps were treated permanently with direct pulp capping.All the cases were followed up in the period of 6 months and two years to examine and evaluate the clinical symptoms,pulp capping vitality,and renovate dentine formation.Results Thirty-four out of 36 deciduous teeth,which were treated with MTA as immediate permanent direct pulp capping,functioned well after two days.In the re-visits after 6 months and two years the teeth showed improved pulp vitality with X-ray detectable detine formation.The survival rate of the pulp using MTA was 94% with two cases of failure.Conclusion MTA should be considered as an ideal direct pulp capping for children in some circumstances.
