1. An illumination device comprising:
at least one light source configured to emit light with a radiant flux and a peak wavelength in a range of 410 nanometers (nm) to 440 nm, wherein the at least one light source is arranged to irradiate the light on tissue within a body cavity;
a lightguide configured to receive the light from the at least one light source; and
a light guide positioner that is configured to secure the light guide for providing the light to the tissue within the body cavity, wherein the light guide extends through the light guide positioner and the light guide positioner is configured to reside at least partially within the body cavity to index a portion of the light guide deeper into the body cavity than the light guide positioner;
wherein the body cavity is an oral cavity and the light guide positioner comprises a biting surface, a first protrusion that extends from only a first portion of the biting surf ace that is above the light guide, and a second protrusion that extends from only a second portion of the biting surface that is below the light guide, the first and second protrusions configured to engage with back surfaces of teeth within the oral cavity such that the light guide positioner expands the oral cavity.
