Abstract | OBJECTIVES: This in vitro study aimed to investigate the protective effect of four commercial novel agents against erosion. METHODS: Ninety human molars were distributed into 9 groups, and after incubation in human saliva for 2 h, a pellicle was formed. Subsequently, the specimens were submitted to demineralization (orange juice, pH 3.6, 3 min) and remineralization ( paste slurry containing one of the tested novel agents, 3 min) cycles, two times per day, for 4 days. The tested agents were: (1) DenShield Tooth; active ingredient: 7.5% W/W NovaMin(®) ( calcium sodium phosphosilicate); (2) Nanosensitive hca; active ingredient: 7.5% W/W NovaMin(®); (3) GC Tooth Mousse; active ingredient: 10% Recaldent™ ( CPP-ACP); (4) GC MI Paste Plus; active ingredients: 10% Recaldent™, 900 ppm fluoride. Two experimental procedures were performed: in procedure 1, the tested agents were applied prior to the erosive attack, and in procedure 2 after the erosive attack. A control group receiving no prophylactic treatment was included. Surface nanohardness (SNH) of enamel specimens was measured after pellicle formation and after completion of daily cyclic treatment. RESULTS: SNH significantly decreased at the end of the experiment for all groups (p<0.05). In both procedures, there was no statistically significant difference between the control group and those treated with paste slurries (p>0.05). In addition, the changes in SNH (ΔSNH=SNHbaseline-SNHfinal) did not show statistically significant difference between both procedures (p>0.05). CONCLUSION:
