Dental caries is defined as a chronic, stereotypically widespread illness which affects child population to variable degree of severity. It is a complex process showing progression involving dietary sugars, bacterial metabolism, demineralization and organic degradation. Dentinal caries is the situation in which caries has progressed into dentine and caused significant loss of structure and lesion depth. Traditional management of dentinal caries has focused primarily on treatment via excision of diseased tissue and subsequent restoration of defect, but it is destructive and irreversible procedure in which healthy dental tissue may get destroyed. The contemporary caries management philosophy has new advancements which changed from traditional approach to medical model, often includes more conservative procedures like fluoride therapy. Among the fluorides agents, silver diamine fluoride is drawing much attention from both researchers and dental clinicians since it has unique abilityto halt caries process and simultaneously prevent new caries, makes it different from other agents.
