摘要:
Devices and methods for cleaning an oral cavity by positioning a device suitable for detecting and removing plaque from the surface within the oral cavity having applied thereto a fluorescent agent capable of binding to plaque on the surface. The surface is substantially simultaneously cleaned and irradiated with a light of a wavelength effective to provide a fluorescent emission when contacted with said fluorescent agent. A portion of the fluorescent emission is collected (APV1), and compared to a predetermined threshold value (PPTV). If APV1 is less than PPTV, the device is moved to another section. If APV1 is greater than or equal to PPTV, then another portion of fluorescent emission is collected (APV2). The percent reduction from APV1 to APV2 determines when the device is moved to another section.

The present invention regards methods and devices for detecting plaque on a surface in the oral cavity to which a fluorescent agent capable of binding to plaque has been applied, whereby a radiation source emits incident radiation for contacting the surface, reflected light and fluorescent emission resulting from contact of the radiation with the surface is collected by an optical collector and conveyed by an optical pathway in the device, where the optical light signal of the reflected light and fluorescent emission is converted to an electrical signal, and where the electrical signals of the fluorescent emission and the reflected light are then mathematically manipulated to provide a compensated plaque value as a function of the distance from the optical collector and the surface of the oral cavity to which the fluorescent agent has been applied.

An apparatus for producing an absorbent article includes a holding tool, a female tool disposed along a machine axis, and a male tool disposed along the machine axis. The holding tool has an aperture aligned along the machine axis and means for holding a flexible sheet across the aperture. The female tool has at least one folding element extending in a direction radially away from the machine axis, and the male tool has means for holding a fluid storage element and at least one pleating blade extending in a direction radially away from the machine axis. At least two of the holding tool, female tool, and male tool are capable of relative motion along the machine axis. Further the at least one pleating blade and of the male tool and the at least one folding element of the female tool are aligned to permit manipulation of the flexible sheet about the fluid storage element.
