1. A method of cleaning the oral cavity, including: a. installing in said oral cavity a device suitable for detecting and removing plaque from the surface of at least one tooth in said oral cavity, where said device comprises a light emitting source, b. substantially simultaneously cleaning and irradiating said surface of at least one tooth in said oral cavity, wherein said at least one tooth is coated with a fluorescent agent capable of binding to plaque on said at least one tooth, said light having a length a wave effective to provide fluorescent emission when interacting with said fluorescent agent on said at least one tooth, c. collecting at least a portion of said fluorescence emission during a predetermined first period of time, d. determining an average plaque value (APV) based on said fluorescent radiation collected during said predetermined first time period, e. comparing said APV with a predetermined plaque value (PPV), f. continuing to substantially simultaneously clean and irradiate said at least one tooth for a predetermined second period of time. The method of claim 1, wherein the reflected light resulting from the interaction of said incident radiation with said surface is collected substantially simultaneously with said fluorescent radiation, and said APV is compensated APV. The method according to claim 1, wherein said fluorescent ag1. Способ очистки полости рта, включающий:a. установку в указанной полости рта устройства, подходящего для обнаружения и удаления зубного налета с поверхности по меньшей мере одного зуба в указанной полости рта, где указанное устройство содержит источник излучения света,b. по существу, одновременно очистку и облучение указанной поверхности по меньшей мере одного зуба в указанной полости рта, где на указанный по меньшей мере один зуб нанесен флуоресцентный агент, способный связываться с зубным налетом на указанном по меньшей мере одном зубе, при этом указанный свет имеет длину волны, эффективную для обеспечения флуоресцен
