Аннотация:
This study aimed at evaluating the remineralization effect promoted by different bioactive fillers on simulated early caries lesions in enamel (ECLE). Forty sound bovine incisors were used to prepare buccal enamel specimens (6 × 6 × 2 mm). The specimens were divided into two areas (3 × 3 mm²): control (CTR) and experimental (EXP). All the enamel specimens were then submitted to a specific protocol for a period of 48 h to induce simulated caries lesions. Subsequently, the specimens were treated for 7 days (2 min, twice a day) with a slurry pastes containing different bioactive particles (P/L ratio: 1 g/mL). All the specimens were analyzed by laser speckle before and after treatments. The results showed after the first analysis that the ECLE had very low average intensity (back-scattered light). Conversely, after application of the bioactive pastes, higher average intensity was always detected; this was comparable to CTR sound specimens. In conclusion, innovative pastes/gels developed fo
