  • Publication number: 20130274724
    Abstract: Architectures and techniques for treating conditions of the eye, such as presbyopia, utilize sources of treatment energy, such as electromagnetic energy emitting devices, to implement non-corneal manipulations. According to these devices and methods, the sources of treatment energy are activated to direct energy onto parts of the eye, such as the conjunctiva and sclera, to treat presbyopia. The treatments can affect at least one property of the eye and enhance an accommodation of the eye.

  • Publication number: 20130273494
    Abstract: A fluid conditioning system is adapted to condition the fluid used in medical and dental cutting, irrigating, evacuating, cleaning, and drilling operations. The fluid may be conditioned by adding flavors, antiseptics and/or tooth whitening agents such as peroxide, medications, and pigments. In addition to the direct benefits obtained from introduction of these agents, the laser cutting properties may be varied from the selective introduction of the various agents.

  • Publication number: 20120282566
    Abstract: An apparatus is used to perform disinfection procedures on target tissues within root canal passages and tubules. The apparatus can include an electromagnetic radiation emitting tip having a distal end and a radiation emitting region disposed proximally of the distal end. According to one aspect, the apparatus can include a porous structure that encompasses a region of the tip excluding the radiation emitting region and that is loaded with biologically-active particles, cleaning particles, biologically-active agents, or cleaning agents for delivery from the porous structure onto the target tissues. Another aspect can include provision of the apparatus with an adjustable channel-depth indicator, which encompasses a region of the tip besides the radiation emitting region and which is movable in proximal and distal directions along a surface of the tip to facilitate the provision of depth-of-insertion information to users of the apparatus.

  • Publication number: 20110281230
    Abstract: A cleaning and whitening system for teeth having an electromagnetic radiation emitting toothbrush and a dentifrice with a photosensitive agent is disclosed. The toothbrush has a cleaning surface, such as bristles. The toothbrush is also adapted to direct electromagnetic radiation toward the cleaning surface. The electromagnetic radiation may be monochromatic or polychromatic. Further, the electromagnetic radiation may be substantially free of ultraviolet radiation, Additionally, the electromagnetic radiation may consist essentially of wavelengths within a range of 300 to 750 nanometers. The photosensitive agent is dispersed throughout the dentifrice. The dentifrice transmits the electromagnetic radiation through a varying thickness disposed over a target surface during use of the system. As a result, a significant portion of the photosensitive agent reacts, resulting in whitening stains, removing and/or disclosing undesired substances, and/or foaming.

The lumen is sized and shaped to accommodate a fiber tip therethrough so that the fiber tip extends through the lumen from the proximal end to the distal end of the generally cylindrical body. The fiber tip fluid output device further includes a plurality of apertures extending around the generally cylindrical body, with each of the apertures of the plurality of apertures fluidly connecting the outer surface to the lumen. Fluid is mixed around the cylindrical body, before entering the lumen through the plurality of apertures for additional mixing.
