Evaluation of the Efficacy of Different Agents on Decontamination of Dental Implant Surface: An In Vitro Study.

Background: The current investigation aimed to evaluate the effectiveness of two different agents in decontaminating the surface of dental implants.

Materials and methods: For this investigation, a total of 45 dental implants were used. In a solution of 40% brain heart infusion (BHI) and 60% entire unstimulated saliva, biofilms were grown on 45 dental implants which were divided into 3 decontamination groups at random (n = 15): Group I: Control group; group II: Ozonated water; group III: Chlorhexidine group. Processed samples were examined using Scanning electron microscopy (SEM) with a backscattered electron detector and a 25 kV image resolution. Data was gathered and analyzed statistically.

Results: The maximum biofilms removed in the 2% chlorhexidine group was 1.24 ± 0.10 followed by the ozonated water group was 1.40 ± 0.01 and the control group was 2.04 ± 0.16. And there was a statistically significant difference found between the three groups. On pairwise comparison, a statistically significant difference was found between the control group vs ozonated water and the control group vs 2% chlorhexidine groups. There was no significant difference found between ozonated water vs 2% chlorhexidine groups.

Conclusion: The present study concluded that both of the decontamination agents employed were successful in removing biofilm from the implant surface. But 2% chlorhexidine group is slightly superior to the ozonated water group in removing biofilm from the implant surface.

Clinical significance: The most crucial steps in treating peri-implantitis are removing polymicrobial biofilm and decontaminating the implant surface. The soft and hard tissues around dental implants are impacted by an inflammatory reaction known as peri-implantitis. At the peri-implant crevice level, the implant and abutment surface are colonized by an aggressive polymicrobial biofilm, so the removal of biofilm is important to prevent the condition.
