Background: As the utilization of dental implants to replace missing teeth becomes more common, so does the incidence of peri-implant diseases, peri-implant mucositis and implantitis, caused by bacterial biofilm. The aim of this study was to evaluate the efficacy of removing bacteria from smooth-surface titanium using an air-polishing device with glycine powder abrasive.
Methods: Smooth-surface titanium discs were inoculated individually with Aggregatibacter actinomycetemcomitans, Streptococcus oralis, Streptococcus mutans, and Tannerella forsythia. Discs were treated with an air-polishing device with glycine powder and water, glycine powder alone, water alone, or tetracycline and water. Bacteria remaining on the surface of the titanium disks were removed and quantified.
Results: Compared with untreated control discs, all treatment types saw a statistically significant reduction in bacteria (p <0.01) regardless of bacterial species. There were no statistically significant differences in bacterial reduction between treatment types. Although not statistically significant, air polishing with glycine powder alone tended to be least effective in reducing total residual bacteria, while Tannerella forsythia showed the least amount of bacterial reduction.
Conclusions: For smooth surface titanium, air polishing with glycine powder and water, glycine powder alone, water alone, or tetracycline and water significantly reduces the amount of Streptococcus oralis, Streptococcus mutans, Aggregatibacter actinomycetemcomitans, and Tannerella forsythia.
