• Abstract:

  Staphylococci is the leading

  etiologic agent of implant-related infection.

  In presence of rock rose (Helianthemum

  nummularium) floral remedy, we evaluated the

  corrosion behavior of commercially pure titanium

  as well as quantified the Staphylococcus aureus

  biofilm formation. To analyze the corrosion

  resistance of pure titanium, electrochemical

  corrosion tests were performed. We submitted

  pure titanium samples into a physiological (pH

  6.50) or pathogenic (pH 2.50) artificial saliva

  environment at 37oC. For the in vitro static

  biofilm assays, a multivirulent Staphylococcus

  aureus strain was used for assessment of

  biofilm formation over pure titanium disks in the

  absence/presence of rock rose floral. Triplicates

  were performed for both corrosion tests and

  biofilm experiments. P values were determined

  by two-way analysis of variance for pairwise

  comparisons (corrosion) and Student’s t-test

  (biofilm assays). Results were considered

  significant when p-value < 0.05. Rock rose floral

  treatment reduced Staphylococcus aureus

  biofilm formation on titanium surface and

  promoted a higher titanium corrosion resistance

  in artificial saliva at low pH. We have shown

  that rock rose remedy can prevent bacteria

  adhesion over the pure titanium in a healthy oral

  environment (pH 6.50) and did not interfere in

  the titanium corrosion response.
