Methodology Overall, 30 caries-free human third molars were sectioned into dentin specimens (n=120) and randomly assigned to control or treatment groups (Curodont™ D’Senz, PRG Barrier Coat, and Curodont™ Repair). After 24 h of artificial saliva storage, dentin microhardness, surface morphology, open dentin tubule count, elemental composition, and penetration depth were evaluated using Vickers microhardness testing, SEM/EDS, and CLSM. Statistical analyses were conducted with a 0.05 significance level. Results The microhardness measurements showed a statistically significant increase in all groups in comparison with the control group (p<0.05), with no significant differences between the treated groups (p>0.05). EDS analysis showed statistically significant differences between the groups, with the highest calcium and phosphorus levels observed in the PRG Barrier Coat group (p<0.05). SEM analysis showed that the PRG Barrier Coat treatment resulted in the most extensive tubule occlusion and the smallest open tubule diameters (p<0.05). Curodont™ D'Senz and PRG Barrier Coat showed the most significant tubule penetration depths and the highest laser fluorescence values, as per CLSM analyses (p<0.001). Conclusion The findings suggested that the tested materials may occlude dentinal tubules and penetrate dentin to varying extents, with PRG Barrier Coat showing the most pronounced effect. Self-assembling peptide-based agents show limited short-term efficacy but offer potential for biomimetic remineralization.
