NCT07767721
Comparison of Three Tongue Cleaners for Removing Tongue Coating
This randomised three-period crossover study compared the effectiveness of three tongue-cleaning devices - a bristled tongue brush, a plastic tongue scraper and a metal tongue scraper - in removing tongue biofilm. Thirty healthy volunteers aged 18 to 30 used each device once daily for 14 consecutive days, with 7-day washout periods between devices during which no tongue cleaning was performed. Tongue biofilm was measured objectively by Quantitative Light-induced Fluorescence-Digital (QLF-D) imaging, alongside the visual Tongue Coating Index, salivary pH, and participant-reported acceptability including gag reflex.

Investigation of Biofilm Formation on Temporary push-on Rings of Implant Crowns
This in-vivo study investigates early (48h), mature (2 weeks) and long-term (3 months) biofilm formation and composition on temporary push-on cones (exchangeable conical rings) made of noble-alloy-based materials (Pagalinor, PA) in comparison to Titanium-6Aluminum-7Niobium alloy (TAN) presently used in the transmucosal portion of dental implant abutments.
