A light curing dental system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure a dental material. The light curing dental system generally includes a light source, a light emitting dental tray, an activation module and a photocurable dental material.

A system and method for modulating optogenetic vagus neurons in a noninvasive and transcutaneous manner is disclosed. The system and method comprises a two-dimensional array of organic light emitting diodes (OLEDs), a voltage-generating unit, a control unit, and a feedback loop. The array is placed on a subject's outer ear. Because the array is flexible, it can be closely placed on the skin of the outer ear. The array can deliver optical therapy and monitor heart rate variability (HRV) of the subject simultaneously, and the pixels of the array can be individually addressed. The voltage-generating unit generates pulsed voltage to the OLEDs. The control unit is connected to the array and controls the array and therapeutic patterns. The feedback loop uses the HRV to identify the therapeutic patterns.

The present invention is directed to a system and method for photoeradication of microorganisms from a target. The target is irradiated with pulsed purple or blue light in which (a) the light pulses have a peak irradiance and a pulse duration sufficient to optically excite a photoactive molecule capable of photoeradication of the microorganisms and (b) the light pulses are separated by an off time sufficient to allow the photoactive molecule to return to a ground state creating an oxidation reaction that produces free radicals which destroy a cellular structure of the microorganisms and thereby photoeradicate all or a portion of the microorganisms. The photoactive molecule may comprise either an endogenous molecule present in the microorganisms or an exogenous molecule applied to the target.
