Ultrasonographic Evaluation of Vascular Response to Mechanical Compression during Induced Gingival Inflammation.

The aim of this study was to evaluate the gingival vascular response to mechanical compression during inflammation using ultrasonography. Four female and 4 male Sinclair mini pigs 18 mo of age were included in the study. Pathogenic bacteria-impregnated silk ligatures were placed around the third premolars (PM3), fourth premolars (PM4), and first molars (M1).

Quantitative Ultrasound for Periodontal Soft Tissue Characterization.

Objective: Periodontal diseases are a spectrum of inflammatory diseases that affect 45.9% of adults aged ≥30 years in the United States Current standard of care in clinics for the assessment of oral soft tissue inflammation is bleeding on probing,which is invasive, subjective and semi-qualitative. Quantitative ultrasound (QUS) has shown promising results in the non-invasive quantitative characterization of various soft tissues; however, it has not been used in clinical periodontics.

Safety, Ergonomics and Patient Centered Point-of-Care Ultrasound.

Ultrasound imaging is a safe diagnostic tool that has become ubiquitous, in part due to its portability, effectiveness, and safety record. The latter is aided be adherence to regulatory limits, safety guidelines, and the "as low as reasonably achievable" principle. Operators receive feedback on potential tissue heating and mechanical effects through output display standard that shows the thermal index and mechanical index.

A Life-Size Three-Dimensional Phantom for Periodontal Imaging Development and Treatment-Planning.

Rationale And Objectives: This study aims to (1) describe a periodontal and implant ultrasound imaging phantom designed for training of common periodontal and peri-implant soft- and hard-tissue deficiencies, and (2) detail the specific anatomical phantom features and showcase imaging data obtained from intraoral scans, cone beam computed tomography (CBCT) as well as ultrasound.

Materials And Methods: A prototype, full-sized, three-dimensional (3D), periodontal ultrasound phantom was created. To mimic periodontal and peri-implant soft-tissue, a phantom material similar to soft-tissue was attached.
