Abstract
A light application unit for a combined photodynamic diagnosis and photodynamic therapy of non-malignant diseases of a parodontium and a tooth of a living being having administered a pharmaceutical preparation allowing the photodynamic diagnosis and the photodynamic therapy comprises a light source, a focusing unit for focusing light emitted by the light source, at least one element arrangeable in a light beam path of the light, and at least one wave guide for transmitting the light from the light source to a distal emitting end, the wave guide is configured rigidly in at least a distal handling end section thereof and being curved in a distal end section.
Claims32
A light application unit for photodynamic diagnosis and for a photodynamic therapy of non-malignant diseases of a parodontium and of a tooth of a living being, comprising:
- a light source for generating a light with a wavelength spectrum lying at least in the visible region;
- a focusing unit for said light;
- at least one element arrangeable in a light beam path of said light generated by said light source, said at least one element altering a spectral property of said light;
- and
- two wave guides for transmitting said light emitted from said light source to a distal emitting end of said two wave guides, said two wave guides positioned adjacent to each other, wherein an emitting end face of one of said two wave guides projects in a distal region beyond an emitting end face of the other of said two wave guides, and wherein one of said wave guides is arranged to be alternately axially extendable and retractable relative to the other wave guide, said two wave guides are configured rigidly in at least a distal region for handling, and said two wave guides being curved in a distal end section thereof.
