Aim: Comparative evaluation of the efficacy of CPP-ACPF and Sodium fluoride with tri-calcium phosphate  on enamel remineralisation using the Diagnodent.

Materials & method: Thirty extracted human premolars were selected and divided into three groups of 10 teeth each: A (artificial saliva), B (CPP-ACPF), C (Sodium fluoride with tri-calcium phosphate -Clinpro 5000). All the samples were assessed using DIAGNOdent at the baseline and after demineralization and remineralisation after 7 days.

Result: Statistical analysis showed that group B(CPP-ACPF) and group C(Clinpro 5000) had significantly higher amount of remineralisation than group A(artificial saliva).

Conclusion: All the three groups showed a statistically significant amount of remineralization. However, Clinpro 5000 showed marginally more amount of remineralisation than CPP-ACPF.
