Rotating titanium brush for plaque removal from rough titanium surfaces--an in vitro study

Area of Science:

• Dental Implantology
• Biomaterials Science

Background:

• Peri-implantitis is a growing concern in dental implantology.
• Conventional treatments for peri-implantitis, such as steel curettes, may cause surface damage.

Purpose of the Study:

• To evaluate the plaque-removing efficacy of a novel titanium rotating brush (TiBrush).
• To compare the TiBrush with conventional steel curettes for plaque removal and surface integrity.

Main Methods:

• Plaque samples from six volunteers were treated with either TiBrush or steel curettes.
• Residual plaque area (RPA) and treatment time were measured.
• Scanning electron microscopy (SEM) assessed surface alterations.

Main Results:

• TiBrush significantly reduced RPA (8.57%) compared to steel curettes (28.99%).
• TiBrush treatment time was significantly shorter (176.7 sec) than with steel curettes (303.5 sec).
• SEM revealed no surface damage after TiBrush use.

Conclusions:

• TiBrush demonstrates superior plaque removal efficacy and gentleness on implant surfaces compared to steel curettes.
• These findings suggest TiBrush could enhance peri-implantitis treatment protocols.
• Further research is warranted to validate these promising results.
