Summary
Biofilm formation on ceramic dental implant materials varied. Antimicrobial-coated material A3 reduced the vitality of Aggregatibacter actinomycetemcomitans in vitro, suggesting potential for improved implant outcomes.
Area of Science:
- Biomaterials Science
- Microbiology
- Dental Implantology
Background:
- Biofilm formation on dental implants is a major cause of implant failure.
- Ceramic biomaterials are increasingly used in implant dentistry due to their biocompatibility.
- Understanding biofilm interactions with different ceramic surfaces is crucial for developing effective implant strategies.
Purpose of the Study:
- To compare in vitro biofilm formation on various ceramic biomaterials intended for dental implant applications.
- To evaluate the impact of different ceramic surface treatments on bacterial adhesion and viability.
- To assess the potential of antimicrobial coatings in preventing biofilm development.
Main Methods:
- In vitro biofilm formation assays using a multi-species oral bacterial consortium.
- Confocal laser scanning microscopy (CLSM) for biofilm visualization and vitality assessment.
- Quantitative polymerase chain reaction (qPCR) with propidium monoazide (PMA) to determine live bacterial cell counts.
Main Results:
- Biofilm formation and bacterial vitality differed significantly across tested ceramic materials (HA, A1, A2, A3).
- Material A3, featuring antimicrobial coatings, demonstrated reduced bacterial vitality, particularly for Aggregatibacter actinomycetemcomitans after 48-72 hours.
- Increased bacterial counts were observed for Aggregatibacter actinomycetemcomitans and Fusobacterium nucleatum on HA, A1, and A2 surfaces.
Conclusions:
- Ceramic biomaterial surface properties influence in vitro biofilm formation.
- Antimicrobial-coated ceramic material A3 shows promise in mitigating bacterial vitality within biofilms.
- Further research is warranted to translate these findings into clinical applications for improved dental implant success rates.

The concept of the looking-glass self describes how an individual's self-concept is shaped by their perception of how others see them. This psychological theory, first introduced by sociologist Charles Horton Cooley in 1902, posits that self-identity emerges in a social context and is influenced by the judgments—real or imagined—of others.Research suggests that individuals frequently overestimate how positively others perceive them. This is particularly evident in physical...

1.3K
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

Clathrin-coated vesicles use endocytosis to transport receptors and lysosomal hydrolases from the Golgi to the lysosome in the late secretory pathway. Clathrin-mediated endocytosis was the first described endocytic process, and Clathrin-coated vesicles remain one of the most well-studied transport vesicles. The molecular machinery that generates clathrin-coated vesicles comprises over 50 proteins that precisely coordinate vesicle formation. Cell surface receptors concentrated in indented sites...

17.4K
Membrane-enclosed structures called vesicles transport proteins and lipids across the cell. The vesicles derive their cargo from the plasma membrane, Golgi, ER, or endosome. Coated vesicles are spherical, protein-coated carriers with a 50–100 nm diameter that mediate bidirectional transport between the ER and the Golgi. The distribution of proteins between the ER and Golgi complex is dynamic and is maintained by different coated vesicles. Their formation is driven by the assembly of...

01:33Coat Assembly and GTPases
4.3K
Vesicles incorporate different coat protein subunits in different cell locations, which changes the properties of the coat, such as the shape and geometry of the transport vesicles. Thus, vesicle coat proteins also play a significant role in cargo selection.
Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...

4.0K
Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...
