Evaluation of Bacterial Load Reduce With Aeropolishing vs Erythritol

Objectives: To evaluate the efficacy of aeropolishing with sodium bicarbonate vs erythritol in reducing the bacterial load of dental implant surfaces in vitro.
Methods: The sample consisted of twenty-four implants (12 JD Evolution and 12 Straumann) were used. Implants were divided into 4 groups: B group: biofilm contaminated implants, treated with airpolishing with sodium bicarbonate (1 minute); E group: biofilm contaminated implants, treated with airpolishing with erythritol (1 minute); NC group (negative control): biofilm contaminated implants; and PC group (positive control): sterile implants. The bacterial culture was prepared with P. gingivalis, S. gordonni and F. nucleatum; each group received the respective decontamination treatment, except groups NC and PC. The results were analyzed by spectrophotometric reading before and after the decontamination protocol.
Results: It was demonstrated that sodium bicarbonate showed a greater decrease in bacterial load of 0.594 with the JD Evolution implant compared to the Straumann implant with 1.867.
Conclusions: The present study concludes that the efficacy of aeropolishing with sodium bicarbonate compared to erythritol was greater in decreasing the bacterial load on the surface of dental implants in vitro.
