Abstract

Objective: This study aims to analyze remineralization that occurred in demineralized dentin following polyaspartic acid (pAsp) in PILP immersion. Methods: Sixteen dentin block samples were immersed in demineralized solution. The samples were divided into controls (no pAsp immersion) or pAsp immersion for 3, 7, or 14 days (n’s=4). The samples were evaluated using a scanning electron microscope (SEM) to observe morphology and energy-dispersive X-ray (EDX) to observe calcium and phosphate levels. Results: SEM revealed that pAsp immersion resulted in significantly higher dentin remineralization compared to the control group. However, there were no significant differences among 3, 7, and 14 days of immersion. EDX revealed that remineralization occurred by the deposition of calcium and phosphate ions. Conclusion: Including pAsp in the PILP process produced rapid remineralization of demineralized dentin.
