Title
(EN) PHOTOACOUSTIC IMAGING FOR NONINVASIVE PERIODONTAL PROBING DEPTH MEASUREMENTS
(FR) IMAGERIE PHOTO-ACOUSTIQUE POUR MESURES DE PROFONDEUR DE SONDAGE PARODONTAL NON INVASIVES
Abstract
(EN)
In alternative embodiments, provided are methods and products of manufacture for photoacoustic imaging of the periodontium of individuals in need thereof for noninvasive periodontal probing depth measurements and periodontal pocket imaging and gingival thickness. In alternative embodiments, products of manufacture as provided herein can observe or measure soft tissue contrast, e.g., gums, the periodontium, or the oral mucosa can be imaged and/or measured.
(FR)
Selon divers modes de réalisation, cette invention concerne des procédés et des produits de fabrication pour l'imagerie photo-acoustique du parodonte d'individus la nécessitant pour des mesures de profondeur de sondage parodontal non invasives et une imagerie de poche parodontale et d'épaisseur gingivale. Selon d'autres modes de réalisation, des produits de fabrication selon l'invention permettent d'observer ou de mesurer un contraste de tissu mou, par exemple, les gencives, le parodonte, ou la muqueuse buccale peuvent être imagés et/ou mesurés.
