ABSTRACT:
A controlled process for thoroughly curing light-activated surgical and dental composites and a process for tissue sterilization is presented using a hand-held, self-contained, cordless, rechargeable laser instrument. At least one solid state microchip laser is pumped by at least one diode laser to generate blue laser light of at most 480 nm. Q-switched, pulsed laser light output enhances efficiency and control of the curing. Another microchip laser within the instrument generates 210-360 nm wavelength of UV laser light for the sterilization process which differentially kills micro-biological life forms contaminating a repair site without killing healthy tissue. The process of use includes switching from sterilization mode to curing mode of operation of the instrument to save time during surgical and dental procedures.
