Objective: Treatment of peri-implant diseases is carried out by controlling the biofilm accumulated on implant surfaces. Decontamination of the surface with chemical agents contributes to the removal of biofilm from the surface more effectively. The aim of this study was to observe and compare the effects of citric acid decontamination protocol applied using two different methods for measuring of surface roughness and surface energy on titanium discs having two different surface characteristics. Methods: 10% CA applied for 4 minutes by immersion or rubbing on 16 machined surface (MS) and 16 sand blasted/acid etched (SA) titanium discs. When the decontamination process and the surface characteristics of the discs were combined, 4 subgroups were created. Surface roughness (Ra, Rz and Rmax) and surface wettability measurements (theta) were made at baseline and post-application. Statistical analyses were conducted to test the significance of the difference between two measurements and the significance of the difference in the results obtained from the 4 groups (P˂.05). Results: Ra increased and the contact angle diminished in all discs in 4 groups (P=.000). Analyses revealed that there was no difference between the MS groups for Ra (P=1.000) and Rz (P=.970) and the change in the Rmax was statistically significant difference between the SA groups (P=.048). Conclusion: Application of CA on the titanium surface causes different physical modifications. While rubbing on SA surfaces caused a decrease in surface roughness parameters, the contact angle decreased on both SA and MS surfaces, regardless of rubbing or immersion.
