High Frequency Intraoral Ultrasound Probe for Early Diagnosis of Periodontal Diseases (Oralus2)

The goal of this clinical investigation is evaluation the agreement between the periodontal pocket depth measurement obtained by periodontal probing (gold standard) and the measurement obtained by the ultrasound device

This is a single-center prospective Clinical Investigation in two steps: Step 1 Preliminary phase : collection and assessment of ultrasonic images to visualize dental and periodontal tissues and structures in order to manually perform periodontal measurements and generate data required for the Artificial Intelligence module training Step 2 : Performance Evaluation : assessment of the ultrasonic probe performance for faster, automatic, accurate and repeatable periodontal measurements in more comfortable conditions for both operator and patient

Imaging/Scanning and recording by Ultrasonic periodontal probing per operator Manual probing per operator with the OMS probe (part of the routine of care)

Imaging/Scanning and recording : Ultrasonic periodontal probing per operator (10 teeth X 6 sites/teeth = 60 probing sites per operator). In addition, 2 teeth per patient will be probed with the ultrasonic probe a second time (2 teeth x 6 sites per tooth = 12 sites per patient) for intra-operator reproducibility purpose. Manual probing per operator with the OMS probe (part of the routine of care)

Tissues and structures (alveolar bone, cementum, CEJ, gingiva, enamel) segmentation/labeling and visual identifications on the obtained ultrasonic images

Manual probing measurements with OMS probe (Periodontal pocket depth, Gingival Margin, Clinical Attachment Level)

Manual probing measurements with OMS probe (Periodontal pocket depth, Gingival Margin, Clinical Attachment Level)

Manunual periodontal measurements (Periodontal pocket depth, Gingival Margin, Clinical Attachment Level) on the ultrasonic images collected and visualized

Manual probing with the OMS probe versus Artificial Intelligence (AI) measurements obtained with the ultrasonic probe
