Truth: Secondary caries remains the main reason for dental restoration failure. And decades of research confirm the role of bacteria in this ongoing problem. So it isn’t surprising that there’s been a ton of recent research investigating the antibacterial properties of dental adhesives and bonding systems.
Being on staff at Dental Product Shopper, I regularly receive alerts, updates, and announcements of ongoing and published research on a multitude of dental topics. For a layperson, I’ve accumulated a fair amount of dental knowledge through 30+ years of osmosis. While I’m not a scientist or a clinician. I do know enough to notice trends. And the words “antibacterial” or “antimicrobial” have become ubiquitous in dental materials research.
Makes sense with the now widespread acceptance of the medical model of caries. Newly developed materials, particularly adhesives and bonding systems, are touting antibacterial ingredients and capabilities in an effort to reduce the risk of secondary caries under restorations. Here are just a few of the recent studies for your reading pleasure……
--This Chinese study concluded that the addition of a specific antibacterial monomer to a commercial dental adhesive improved its ability to inibit the growth of S. mutans.
--Published in JADA, a study compared the antibacterial properties of four available self-etching bonding systems.
--This in vitro study also measured the antibacterial efficacy of available dentin bonding systems.
--This University of Maryland study found that a combination of antibacterial ingredients and remineralizing nanoparticles may have wide applicability in dental adhesives to inhibit caries formation.
--This Indian study specifically tested the comparative antimicrobial action between total-etch and self-etch bonding systems, noting that the acidity of the adhesive may affect the ability to inhibit carie-causing bacteria.
