A clinical comparison of three powered toothbrushes

Area of Science:

• Oral hygiene research
• Periodontology
• Biomedical engineering

Background:

• Gingivitis and plaque accumulation are common oral health issues.
• Effective plaque control is crucial for preventing gingivitis and periodontal disease.
• Power toothbrushes offer potential advantages in oral hygiene efficacy.

Purpose of the Study:

• To compare the efficacy of Braun Oral-B 3D Excel (BPT), Sonicare (SPT), and Philips Sensiflex 2000 (PPT) power toothbrushes.
• To evaluate their ability to control plaque and reduce experimentally induced gingivitis.

Main Methods:

• A split-mouth design was employed in two experiments over a 4-week treatment period.
• Subjects brushed with assigned power toothbrushes, with plaque index and bleeding tendency assessed.
• A run-in period established gingivitis levels and allowed familiarization with toothbrushes.

Main Results:

• The Braun Oral-B 3D Excel (BPT) demonstrated a more rapid and significant reduction in gingivitis bleeding scores compared to SPT and PPT (P < 0.05).
• No significant differences in plaque index reduction were found between BPT and SPT, or BPT and PPT.
• A majority of participants expressed a preference for the BPT in post-study questionnaires.

Conclusions:

• The Braun Oral-B 3D Excel power toothbrush exhibits superior effectiveness in resolving gingivitis compared to Sonicare and Philips Sensiflex 2000.
• Its design and action contribute to better gingivitis management.
• User preference favored the Braun Oral-B 3D Excel, suggesting a positive user experience.
