An in vitro comparative evaluation of casein phosphopeptide-amorphous calcium phosphate fluoride, tricalcium phosphate and grape seed extract on remineralization of artificial caries lesion in primary enamel

Objectives: To evaluate and compare the remineralization potential of casein phosphopeptide-amorphous calcium phosphate fluoride, tricalcium phosphate and grape seed extract on artificial caries lesions in primary enamel. Study design: A sample of 40 non-carious, primary molar teeth was collected and cut in longitudinal sections into three equal halves. Those 120 samples were divided into four equal groups. Group A: Sections treated with casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF), Group B: Sections treated with tricalcium phosphate, Group C: Sections treated with grape seed extract Group D: Sections treated with deionized water (control group). Samples were evaluated for change in surface characteristics, mineral content using Scanning electron microscopy-energy dispersive X-ray analysis (SEM-EDX) and microhardness using Vicker’s microhardness tester. Cavitated lesions were evaluated for Cone beam computer tomography to obtain baseline data post remineralization. Results: The reminer-alization potential of grape seed extract was found to be greater compared to tricalcium phosphate followed by CPP-ACPF. Conclusion: All the three groups viz. CPP-ACPF, tricalcium phosphate and grape seed extract showed remineralization under the in vitro pH cycling model, while grape seed extract group showed significantly greater remineralization compared to the CPP-ACPF and tricalcium phosphate groups.
