Characteristics of the studies compared SDF to MTA in indirect pulp capping of primary teeth.

Author-date	site	study design	Number and Age of children	Number and type of teeth	Method of assessment	SDF Clinical/radiographical	MTA Clinical/radiographical	Final restoration
Divyashree et al., - 2021	India	randomized controlled in vivo study	75 children 6–9 years of both sexes	75 teeth Primary molar 25 SDF 25 CAOH 25 MTA	Clinical success criteria: no pain, no sensitivity to percussion, no swelling and/or fistula, no pathologic tooth mobility, retention of the restoration (Marginal integrity) Radiographic success criteria: formation of reparative dentine, no radiolucency in periapical or furcation area, no widening of periodontal ligament space, no external or internal resorption	The success of 38% SDF was evaluated using PA and Corel draw software. The reparative dentine formed was around 0.0076 mm by the end of 6 months from baseline. This gives a statistically significant P- Value of 0.001 SDF showed the lowest amount of reparative dentin formation among all three groups.	The success of MTA was evaluated using PA and Corel draw software. The reparative dentine formed was around 0.1166 mm by the end of 6 months from baseline	All teeth were restored with Resin Modified Glass Ionomer Cement RMGIC to ensure a proper seal
