An In Vitro Evaluation of Remineralization Potential of Functionalized Tricalcium Phosphate Paste and CPP-ACPF on Artificial White Spot Lesion in Primary and Permanent Enamel

Abstract

Aim: Investigation and evaluation of remineralization potential of functionalized tricalcium phosphate paste (fTCP) and casein phosphopeptide-amorphous calcium phosphate (CPP-ACPF) paste on artificially created white spot lesion on human primary and permanent enamel through scanning electron microscopy and microhardness assessment.

Materials and methods: Sixty freshly extracted primary and permanent teeth were selected and artificial white spot lesion were created by using standardized demineralizing solution. Remineralization was carried out using the test pastes. The assessment of demineralization and remineralization was done through a scanning electron microscope and microhardness assessment.

Results: Among the three groups, fTCP shows significantly higher increase in mean microhardness (p < 0.001) through ANOVA and the LSD post hoc test when compared to CPP-ACPF and control group. Also, the unpaired t-test showed that mean change in microhardness in permanent teeth was significantly higher than primary teeth in different time intervals for both experimental groups. Surface morphology was assessed through a scanning electron microscope.

Conclusion: Based on the results of the current study, f-TCP showed comparatively more remineralization potential than CPP-ACP with fluoride.
