Potential Combination of Acemannan Sponge and Calcium Phosphate Cement-Calcium Sulfate Hemihydrate (CPC-CSH) as Direct Pulp Capping Alternative Materials for Reparative Dentin Formation

Abstract

Abstract Background  Health problem that affects hard tissues of the teeth is dental caries, which is experienced by around 2.3 billion people in the world, with prevalence in Indonesia reaching 88.8. Direct pulp capping (DPC) is a vital pulp therapy used to maintain pulp vitality. Calcium hydroxide (Ca(OH) 2 ) is the gold standard pulp capping material, but has poor adhesion to dentin and mechanical properties, bacterial infiltration, formation of tunnel defects in the pulp resorption, and dentin bridge. Therefore, it is necessary to develop alternative therapy, namely, a combination of acemannan sponge and calcium phosphate cement (CPC)-calcium sulfate hemihydrate (CSH) for reparative dentin formation. Purpose  This article describes the potential combination of acemannan sponge and CPC-CSH as DPC alternative materials for reparative dentin formation. Reviews  Acemannan extracted from aloe vera exhibits anti-inflammatory, antimicrobial, and cytocompatibility properties. As DPC material, acemannan induces pulp proliferation and differentiation to osteoblast-like, growth factor synthesis, and promotes reparative dentin formation. However, acemannan sponge is radiolucent, allowing misinterpretation between pulp and acemannan sponge. CPC can be combined with CSH to shorten the setting time. CPC-CSH is radiopaque, has good compressive strength, and biocompatibility. CPC-CSH is a calcium-based material with neutral pH that can induce the dentin bridge formation. CPC-CSH showed good bioactivity because it induces the formation of apatite which plays a significant part in dentin and pulp regeneration. Conclusion  The combination of acemannan sponge and CPC-CSH has the potential as DPC alternative materials for reparative dentin formation.
