Methodology: Children aged 5- 9 years were screened and those who fulfilled the inclusion criteria were selected. Accordingly seventy five children were divided into 3 groups with 25 patient in each group. Cavity preparation was done and the three test materials (Dycal, MTA and SDF) were placed at the base in their respective groups and restored with RMGIC. Post-operative radiograph was taken for baseline data. Patients were assessed at Subsequent at 1, 3 and 6 months both clinically and radiographically.

Results: SDF had formed a good biological seal, arrested further caries progression and did not cause any adverse pulpal reaction. However the amount of reparative dentin formed was highest in the Dycal group followed by MTA group and SDF group.
