A 2025 pilot study using 20 MHz intraoral ultrasonography in 13 periodontitis patients demonstrates that ultrasound can reliably visualize periodontal structures and distinguish tissue types based on echogenicity . Enamel showed the highest pixel intensity, while inflammatory tissue displayed markedly reduced echogenicity—forming a clear diagnostic contrast ( p < 0.001 ). Real-time imaging also identified subgingival calculus and deep inflammatory pockets in most patients, with LDA and clustering analyses supporting echogenicity-based tissue separation.
These findings highlight ultrasound as a feasible, non-invasive modality for dynamic periodontal assessment , with strong potential for chairside inflammation detection and future AI-assisted diagnostics.
