Article Synopsis
- - The study aimed to evaluate and compare the antibacterial properties of two types of titanium dioxide coatings on dental implants: one made with atomic layer deposition (ALD) and the other with anodic oxidation (AO).
- - ALD coatings showed a smoother surface and significantly reduced bacterial adhesion by over 50%, similar to the performance of zirconia surfaces, whereas AO coatings had no effect on bacterial adhesion despite having a different surface texture.
- - The results suggest that ALD-coated titanium abutments could effectively prevent bacterial infections like peri-implantitis, while AO coatings did not provide adequate resistance against bacterial adhesion.
Article Synopsis
- Alveolar bone defects from tumors, trauma, or inflammation impair oral function and complicate denture fitting, highlighting the need for improved regenerative materials.
- The study introduces a new hydrogel membrane (CF-Cu) made from methacrylated carboxymethyl chitosan, silk fibroin, and copper nanoparticles, which shows better properties than existing GBR membranes, including stability and antibacterial effectiveness.
- In vitro tests reveal that CF-Cu has excellent cell compatibility, can significantly inhibit bacteria, and promotes bone cell growth, suggesting it's a promising option for guided bone regeneration therapies.
Controlling infections while reducing the use of antibiotics is what doctors as well as researchers are looking for. As innovative smart materials, photothermal materials can achieve localized heating under light excitation for broad-spectrum bacterial inhibition. A polydopamine/chitosan/β-glycerophosphate temperature-sensitive hydrogel with excellent antibacterial ability is synthesized here.

- The study investigates how different dental polymers, made through various manufacturing techniques, affect surface properties and microbial adhesion, particularly focusing on the impact of thermocycling (repeated temperature changes).
- Six types of dental polymers were tested for surface roughness and hydrophobicity before and after thermocycling, followed by incubation with specific bacteria and fungi to assess microbial adhesion levels.
- Results indicated that CAD/CAM polymers displayed lower microbial adhesion compared to conventional polymers, showing that surface roughness mainly influences adhesion, while thermocycling generally increased surface roughness and microbial adhesion for most materials.
