Research progress on natural antibacterial ingredients of glass ionomer cement / 口腔疾病防治

ABSTRACT

@#Glass ionomer cement (GIC) is widely used as a common filling material in dentistry but still exhibits problems with secondary caries and fractures. Thus, the antibacterial and anti-caries performance of GIC needs to be further improved. In recent years, natural antimicrobial components have become more desirable due to their good biological properties and low drug resistance. In this review, the natural antimicrobial ingredients in GIC modification are classified, reviewed and summarized according to the different sources of antimicrobial ingredients. In terms of animal origin, chitosan and casein phosphopeptide-amorphous calcium phosphate exhibit antimicrobial properties without affecting the mechanical properties of materials; propolis and bioactive enzymes have good biocompatibility; in terms of plant origin, polyphenols help improve the antimicrobial and mechanical properties of the material; arginine has a good remineralization effect; and plant essential oils have a certain ion release effect. In terms of microbial origin, antibiotics greatly improve the antibacterial properties of materials; in addition, the combined application of natural antimicrobial ingredients also exhibited excellent performance. Despite these advantages, the optimal addition concentration and biocompatibility in vivo are questions that need to be further explored before clinical applications can be achieved.
