nanodiamonds implants root canalWhile nanodiamonds are known already for a while, the new research revokes the interest in these tiny particles in medical applications. Inspired by former findings that nanodiamonds improve the mechanical properties of polymers, including dental implants (Dental Materials Journal, 2011; 30(2):222), researchers from the University of California, have decided to try nanodiamonds in root canal implants, which are usually made of mechanically poor gutta percha. In parallel, amoxicillin, an antibiotic molecule was added to the polymer. A parallel experiment with the same compound, but without an antibiotic was made. To the surprize of the authors, aside of the great increase in the mechanical strength of the polymer, pure nanodiamonds without the drug have also demonstrated a strong antibacterial effectiveness. This finding recently published in ACS Nano (http://pubs.acs.org/doi/abs/10.1021/acsnano.5b05718?src=recsys) opens a previously unknown potential of diamond nanoparticles to be used in endodontic therapy as well as probably in other types of implants.
