Trehalose Air-Polishing Powder: What the 2025 Meta-Analysis Found
A 2025 network meta-analysis pooling nine randomized controlled trials and 462 patients ranked erythritol, trehalose, and glycine as subgingival air-polishing powders. No statistically significant pairwise differences on probing depth, attachment, or bleeding — but the SUCRA scores tell a more nuanced story. Verbatim numbers, primary source (Zi-le et al., Frontiers in Physiology, DOI 10.3389/fphys.2025.1593204), and where trehalose fits in 2026 practice.
Air Polishing for Peri-Implantitis in Severe Periodontitis: What the 2026 BMC RCT Found
Dai et al. (BMC Oral Health 26:192, DOI 10.1186/s12903-026-07721-z) randomized 40 stage III/IV periodontitis patients with peri-implantitis to submarginal erythritol air-polishing vs ultrasonic+manual debridement. PPD at 3 months: no significant difference. Soft-tissue inflammation (mSBI) significantly lower in the air-polishing arm. Keratinized mucosa width ≥ 2 mm raised odds of PPD ≤ 5 mm by ~9.8×.
Air Polishing and Aerosol Contamination: What the 2025 Evidence Shows
A 2025 observational study by Mensi et al. (Int J Dent Hyg, DOI 10.1111/idh.12881) found air polishing did not raise airborne bacterial counts above the empty-clinic baseline of 1.45 CFU/L. The highest contamination came from turbine cavity prep with low-volume evacuation, at 7.38 CFU/L. Evacuation choice is the variable that matters.
Hu-Friedy debuts PWR Air at Chicago Midwinter 2026: what the manufacturer disclosed
At Chicago Midwinter 2026, Hu-Friedy introduced PWR Air — a dedicated air-polishing device with dual powder chambers and one-touch switching between supra- and subgingival modes. We cover what's publicly disclosed and what isn't.
Can You Use Air Polishing on Implants? Evidence & Clinical Protocols
Yes — glycine and erythritol are safe and evidence-supported on titanium. Sodium bicarbonate is not. What the 2023–2025 systematic reviews (Delucchi, Bi) show, the powder-selection rule that follows, and the EU-specific availability note that matters in practice.
