Title
(EN) METHOD FOR PLAQUE DETECTION
(FR) PROCÉDÉ DE DÉTECTION DE PLAQUE
Abstract
(EN)
Method of detecting dental plaque, comprising the steps of subjecting a dental area of interest to high and low energy photons in the presence of a photosensitizer. The invention can be used antimicrobial and antiviral and antifungal detection and therapy. Thus, generally, viral or fungal infections in biofilm, plaque and on teeth surfaces can be detected and optionally treated. The method can also be used for detecting, determining or analysing the quantity or quality or both of the dental pellicle.
(FR)
L'invention concerne un procédé de détection de plaque dentaire, comprenant les étapes consistant à soumettre une zone dentaire d'intérêt à des photons de haute et basse énergie en présence d'un photosensibilisateur. L'invention peut être utilisée pour la détection et la thérapie antimicrobiennes et antivirales et antifongiques. Ainsi, de manière générale, les infections virales ou fongiques dans le biofilm, la plaque et les surfaces des dents peuvent être détectées et éventuellement traitées. Le procédé peut également être utilisé pour détecter, déterminer ou analyser la quantité ou la qualité ou les deux de la pellicule dentaire.
