This biomaterial calcium silicate is manufactured to have an anti-bacterial effect on micro-organisms within the dentin, thus allowing the inhibition of bacterial growth therefore no caries will progress. Material is injected and light-cured within the dentin and sealed with a restoration.

Antibacterial Effect of Light-activated Calcium Silicate Versus Light-activated Calcium Hydroxide

Antibacterial Effect of Light-activated Calcium Silicate Versus Calcium Hydroxide on Permanent Carious Molars Treated With Step-wise Excavation (A Randomized Clinical Trial)

will be done by Digital colony counter, Agar Diffusion Test The measuring unit of the bacterial count is CFU/ml(colony-forming units per milliliter) for liquids). The first dentin sample will be collected in the baseline time and the second dentin sample after 6 month for each group.
