SHERIDAN, WYOMING – April 1, 2025 - Breakthrough Research Underscores Oral-B iO’s Leadership in Oral Health Innovation
A newly published meta-analysis in the International Dental Journal has delivered a resounding endorsement for Oral-B’s groundbreaking iO technology, positioning it as a superior solution in the field of professional oral care. Based on 46 randomized controlled trials (RCTs) with more than 3,000 participants from North America, Europe, and Asia, the findings mark a significant milestone in the fight against gingivitis and periodontal disease.
Accelerated Gingival Health Improvements with iO Technology
The comprehensive analysis revealed that individuals with gingival issues who used the Oral-B iO toothbrush achieved healthy gum conditions 50% faster than manual toothbrush users and 33% faster than sonic toothbrush users. Notably, 88% of Oral-B iO users reached gingival health, compared to only 21% and 54% for manual and sonic toothbrush users respectively.
“Mit der Oral-B iO Technologie haben wir das Zähneputzen revolutioniert: Durch sanfte, aber kraftvolle Mikrovibrationen in Kombination mit unserem einzigartigen magnetischen Antriebssystem ermöglichen wir eine deutlich bessere Plaqueentfernung – und das überraschend sanft,” explains Philipp Hundeshagen from the Research and Development team at Procter & Gamble. “So vereinen wir Präzision und Anwendungskomfort in einer völlig neuen Dimension der Mundpflege.”
Marked Reduction in Bleeding and Superior Plaque Removal
In addition to accelerated gum health, the iO technology also demonstrated a 62% stronger reduction in bleeding sites compared to manual toothbrushes, and 27% greater effectiveness than sonic toothbrushes. The brush significantly outperformed both manual and sonic models in plaque removal, contributing to more sustainable oral health outcomes (p < 0.001).
“Diese Ergebnisse unterstreichen die langfristige Überlegenheit der iO-Technologie – ein entscheidender Fortschritt im Kampf gegen Gingivitis und Parodontitis,” the report concludes.
Data-Driven Analysis Reinforces Clinical Impact
The meta-analysis draws from P&G’s Clinical Archive (2007–2022) and uses validated clinical indices such as the Turesky-Quigley-Hein Index and the Rustogi Navy Plaque Index. The health outcomes follow the periodontal standards defined by Trombelli et al. (2018), recognizing a healthy state as having fewer than 10% bleeding sites.
These rigorous evaluation metrics confirm that Oral-B iO is not only effective in the short term but also provides sustained benefits—backed by five independent meta-analyses published since 2020, all reinforcing the superior performance of oscillating-rotating toothbrushes.
The iO Technology: A Turning Point in Modern Oral Care
Introduced in 2020, the iO line redefined brushing standards with its innovative linear magnetic drive and micro-vibration-enabled bristles. The trusted round Oral-B brush head combines advanced performance with intelligent features like real-time pressure control to guide users toward optimal brushing habits.
With over 60 years of dedication to improving access to oral care, Oral-B’s latest advancements reflect a continued commitment to both in-home users and dental professionals alike.
Proven by Independent Testing
Oral-B's iO technology continues to receive top marks from independent testers. Most recently, Stiftung Warentest rated the Oral-B iO3 as “GUT” (1.9), crowning it as the test winner in the December 2024 evaluation.
