In brief: Gold nanoparticles perform better than chlorhexidine, jury makes award in oral cancer case


Dentist hit with $11M verdict for failure to diagnose tongue cancer

A Pennsylvania dentist has been ordered to pay an $11 million verdict, including $8 million in punitive damages, for failing to investigate a patient’s tongue sore, which turned out to be cancerous. The dentist was also accused of attempting to cover up the mistake by withholding and destroying dental records.

According to publiclawlibrary.org, “the punitive damages reflect the jury’s belief that the defendant’s actions were intentional and deserving of punishment.”1

The case underscores the critical importance of oral cancer screening and timely diagnosis or referrals, as well as the legal ramifications of withholding patient records.

DentistryIQ’s sister publication RDH has compiled several excellent resources on oral cancer screening.

Sugar-coated gold-in-gold cage nanoparticles outperform chlorhexidine

Researchers at the University of Pennsylvania and Stanford University have devised a novel, antibiotic-free strategy for disrupting biofilm in oral plaque and wound infections: dextran-coated gold-in-gold nanoparticles.2

The photoacoustic and photothermal properties of the nanoparticles work when activated by a near-infrared laser. The sound waves emitted by the nanoparticles allow for imaging of the biofilm, and the heat generated destroys bacteria.

The technology was effective against both Streptococcus mutans and Staphylococcus bacteria. The researchers tested their strategy by applying the particles to S. mutans-infected teeth from ex vivo rat jaws. They compared its effectiveness to chlorhexidine applied to the same type of tooth sample. The study abstract writes that “these effects were over 100 times greater than those seen with chlorhexidine, a conventional antimicrobial agent. Moreover, this approach did not adversely affect surrounding tissues. We concluded that photothermal ablation using theranostic nanoparticles is a rapid, precise, and nontoxic method to detect and treat biofilm-associated infections.”3
