Killing Dental Pathogens Using Antibacterial Graphene

Dental caries and periodontal diseases have a close relationship with microbes such as Streptococcus mutans, Porphyromonas gingivalis and Fusobacterium nucleatum. Graphene oxide (GO), as the derivative of graphene, plays an important role in many areas including biology and medicine. In particular, it has been known as a promising antimicrobial nanomaterial. In this study, we focused on

Nanoparticle technology and its implications in

2020/12/4Zirconia, a chemical oxide, has been considerably used in dentistry due to its optical and metallic properties similar to the tooth. ZrO 2 is proven to be a high-performance ceramic material due to its high toughness, strength, corrosion resistance and great chemical properties.

Calcium phosphate cement (CPC), functionalized with iron oxide nanoparticles (IONP), is of great promise to promote osteoinduction and new bone formation. In this work, the IONP powder was added into the CPC powder to fabricate CPC + IONP scaffolds and the effects of the novel composite on bone matrix formation and osteogenesis of human dental pulp stem cells (hDPSCs) were explored.

Frontiers

The latest study found a surprising improvement in the bactericidal activity of ZIF-8 functionalized with graphene oxide (GO) (Ahmad et al., 2020). When the ratio of GO to ZIF-8 was 1–100, ZIF-8/GO composites exhibited fivefolds of the antibacterial properties of the original ZIF-8 at the same concentration against S. aureus and E. coli .
