Bioelectric Effect of a Microcurrent Toothbrush on Plaque Removal

Area of Science:

• Biomedical Engineering
• Dental Science
• Oral Health

Background:

• Gingivitis and plaque buildup are common oral health issues.
• Biofilm removal is crucial for managing gingivitis.
• Novel technologies for improved oral hygiene are continuously explored.

Purpose of the Study:

• To evaluate the effectiveness of a microcurrent toothbrush (Proxywave® technology) in plaque removal and gingivitis reduction.
• To compare the efficacy of the microcurrent toothbrush against a control toothbrush.
• To assess the safety of the microcurrent toothbrush.

Main Methods:

• A randomized controlled trial involving 40 volunteers with gingivitis.
• Participants used either the Proxywave® toothbrush (PB) or a control toothbrush (CB) for two-week periods, with a two-week washout interval.
• Plaque Index (PI) and Gingival Index (GI) scores were recorded every two weeks.

Main Results:

• Both toothbrushes significantly reduced PI and GI scores (p < 0.05).
• No significant difference in PI was observed between the PB and CB.
• The PB demonstrated a significant reduction in interproximal GI compared to the CB (p < 0.05), indicating effectiveness in areas difficult to reach.

Conclusions:

• The microcurrent toothbrush (Proxywave® technology) is safe and effective for plaque removal.
• It offers a significant benefit in reducing gingivitis, especially in interproximal areas.
• This technology presents a promising advancement in maintaining oral hygiene.
