The effect addition of epigallocatechin-3-gallate (EGCG) in nano hydroxyapatite on surface porosity as a candidate pulp capping materia

Background: Deep caries, cavity preparation and use of burs or other dental instruments often result in pulpal perforation. In the case an exposed pulp, regenerative pulp tissue treatment aims to regenerate normal maintain vitality by inducing regeneration using right material, so that a good percentage size material porosity is needed help cell supporting proliferation attachment, stimulating remineralization differentiation odontoblast-like cells. Nano-HA has ability produce dentine bridges continuously, porous properties allow growth, improves mechanical properties, but not anti-inflammatory EGCG added which advantage being antioxidant, can optimize also acts as antimicrobial reduce growth bacteria oral trigger human Purpose: This study prove difference surface nano hydroxyapatite with compared aquadest. Methods: used laboratory experimental posttest-only control group design. The research sample consisted 32 samples were divided into 2 groups, (nano HA - EGCG) aquadest). Each was subjected freeze drying SEM tests. Results: There significant between aquadest.on results Independent T-test (p<0.05). Conclusion: addition higher
