Indirect and Direct Pulp Therapy in Primary Second Molars

Ankara University45 enrolled

Overview

The purpose of this randomized controlled clinical trial was to compare the clinical and radiographic outcomes of indirect pulp treatment (IPT) and direct pulp capping (DPC) using mineral trioxide aggregate (MTA) in deep carious primary molars. Children with deep dentin caries in primary molars were randomly assigned to receive either IPT or DPC. Clinical and radiographic evaluations were performed at 6 and 12 months to assess treatment success. The findings of this study aim to provide evidence-based guidance for the management of deep dentin caries in primary teeth.

Deep Dentin Caries in Primary Teeth Pulp Therapy in Primary Molars

Interventions

Indirect Pulp TreatmentPROCEDURE

Selective caries removal was performed, leaving affected dentin over the pulp. Mineral trioxide aggregate (MTA) was placed, followed by restoration with a stainless steel crown (SSC).

Direct Pulp CappingPROCEDURE

After \<1 mm pulp exposure, mineral trioxide aggregate (MTA) was placed directly over the exposed pulp tissue, followed by restoration with a stainless steel crown (SSC).

Outcomes

Primary Outcomes

Clinical success of indirect pulp treatment and direct pulp capping

Clinical success was defined as the absence of spontaneous pain, swelling, fistula, pathological mobility, or tenderness to percussion.

Time frame: 12 months

Radiographic success of indirect pulp treatment and direct pulp capping

Radiographic success was defined as the absence of periapical radiolucency, internal or external root resorption, pathological changes, or other radiographic signs of pulpal or periapical pathology during the follow-up period.

Time frame: 12 months

Secondary Outcomes

Effect of pulp exposure location on treatment success

The location of pulp exposure (occlusal or proximal) was recorded and its association with clinical and radiographic success of vital pulp therapy was evaluated.

Time frame: 12 months
