Method of treating biological surfaces with electromagnetic radiation in the form of light of two different energy levels, a first light with photons having a majority energy in the range from 3.5 eV to 2.8 eV and a second light with photons having a majority energy in the range from 1.24 eV to 2.48 eV. The photons of the first light and the second light are simultaneously directed against the biological surface. The invention also contemplates the use of sensitizers in topical treatments of infections using the method. The treatment will achieve good tissue penetration. It makes it possible to give antibacterial treatment to different areas of pathogen at the same time as two or more different energy photons can target molecules in different areas.

UV LEDs are disposed along the channels at the respective teeth facing services. The UV LEDs are interspersed with the transducers.

The present invention is an oral heating element designed to apply heat and increase blood circulation along the gums to prevent and treat gum disease. The oral heating apparatus is designed to fit inside the mouth for extended periods of time. The heating element has a heating filament encased in a food safe plastic sheath capable of transmitting heat evenly along the surface of the sheath facing the gums.

The present invention is directed to a system and method for photoeradication of microorganisms from a target. The method includes the step of obtaining test data for a plurality of experiments each of which comprises irradiating test microorganisms with a plurality of light pulses having a wavelength that ranges from 380 nm to 500 nm. The light pulses have a plurality of pulse parameters (peak irradiance, pulse duration, and off time between adjacent light pulses) and are provided at a radiant exposure that ranges from 0.5 J/cm.sup.2 to 60 J/cm.sup.2 during each of a plurality of irradiation sessions. The test data comprises a survival rate for the test microorganisms after irradiation with the light pulses. The method also includes the step of analyzing the test data to identify the pulse parameters for the light pulses and the radiant exposure for each of the irradiation sessions that result in a desired survival rate for the test microorganisms. The method further includes the step of irradiating the microorganisms of the target with light pulses having the identified pulse parameters at the identified radiant exposure for each of the irradiation sessions so as to photoeradicate all or a portion of the microorganisms.

The light therapy device for treatment of the vagina and vulva includes internal and external sections. The internal section is for treatment of the vagina, the external section is for treatment of the vulva. A frame joins the two primary components of the device: an insertion structure that is covered in a pliable cover, and a flexible wrap. Insertion structure is for internal treatment of the vagina. These insertion structure includes a rigid or semi rigid body that supports two sets of leads. An external wrap provides light therapy to the vulva. The wrap includes a flexible LED array that allows the user to contour the wrap to the shape of her body while maintaining electrical continuity to avoid damage to the LEDs.
