Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Detection and expression analysis of tet(B) in Streptococcus oralis. [PDF]

J Oral Microbiol, 2019
Tetracycline resistance can be achieved through tet genes, which code for efflux pumps, ribosomal protection proteins and inactivation enzymes. Some of these genes have only been described in either Gram-positive or Gram-negative bacteria. This is the case of tet(B), which codes for an efflux pump and, so far, had only been found in Gram-negative ...

Emerging locally delivered antimicrobial and immunomodulatory approaches for the prevention/treatment of peri‐implant diseases

Periodontology 2000, EarlyView.
Abstract Peri‐implant diseases are dysbiosis‐mediated inflammatory disorders that occur in susceptible hosts. Antimicrobials and immunomodulatory agents therefore might be pertinent as adjunctive measures in the treatment of such disorders. The aim of this narrative review was to examine the existing evidence and assess the effectiveness of emerging ...
