Chemotherapeutic agents to treat peri-implantitis?

Should Chemotherapeutic agents (ChAs), because of their antimicrobial effect, be considered an integral part of current treatment protocols for peri-implantitis? This study 1, investigated whether ChAs residues alter titanium physicochemistry and thus compromise cellular response to decontaminated surfaces..

The study concluded:

ChA-specific residues left on the titanium surfaces altered titanium physical properties and adversely affected the osteoblastic response irrespective of their observed antimicrobial effect. Chlorhexidine may compromise the biocompatibility of titanium surfaces, and its use is not recommended to detoxify implants. Sterile saline, citric acid, and NaOCl-EDTA may be proposed for use in the treatment of peri-implantitis. Contrary to previous studies that recommended the selection of ChAs for the decontamination of titanium implants according to their antimicrobial effects, the present study demonstrated that the restoration of the biocompatibility of contaminated titanium surfaces is also contingent on the preservation of titanium material properties.

  1. Hi,
    Thanks for that great information.
    Can you kindly point us ( your readers ) to this study online so we can review it.
    Some questions that come to mind:
    –Do the authors sight specific instances of bone loss/fixture failure that can be directly attributed to chlorhexidine usage ?
    –Is the study just an in-vitro ( laboratory ) analysis…….or are implants/subjects examined in-vivo ?
    Are these conclusions cited in any other studies ?
    Thanks again for the information.
