Efficacy of Air-Polishing with Sodium Bicarbonate vs. Erythritol in the Decrease of the Bacterial Concentration on the Surface of Dental Implants: In Vitro Study
Source abstract
Abstract
Dental implants are recognized as one of the most effective long-term solutions for the replacement of one or multiple missing teeth, addressing both aesthetics and functionality. However, one of the leading causes of implant failure is peri-implant diseases. This study aims to evaluate the effectiveness of air polishing with sodium bicarbonate compared to erythritol in reducing the bacterial concentration on dental implant surfaces in vitro. A sample of twenty-four implants (12 JD Evolution and 12 Straumann) was utilized and divided as follows: 10 implants contaminated with biofilm treated with sodium bicarbonate air polishing (1 min); 10 implants contaminated with biofilm treated with erythritol aeropolishing (1 min); two implants contaminated with biofilm (negative control); and two sterile implants (positive control). The entire experiment was performed in triplicate. The bacterial culture included P. gingivalis, S. gordonii, and F. nucleatum. Optical density (OD) at 600 nm was measured before and after the decontamination protocol to analyze the results. The JD Evolution implant demonstrated a slightly greater reduction in bacterial concentration, but the difference was not statistically significant (p > 0.05). Similarly, no differences were observed between erythritol and sodium bicarbonate in the Straumann implants. An increase in surface roughness is observed in the JD Evolution implant treated with erythritol, whereas the one treated with bicarbonate exhibits a smoother surface compared to the untreated implant. The findings suggest that air polishing with erythritol is as effective as sodium bicarbonate in reducing the bacterial concentration on dental implants in vitro. This could suggest the use of erythritol during air polishing due to its antimicrobial capacity and its increase in surface roughness on implant surfaces compared to bicarbonate.
