Claim:
1. A dental hand tool for delivery of disinfected dental fluid under pressure to a dental patient comprising a main body having a main body proximate end, a main body distal end, and at least one conduit associated with the main body proximate end, and a detachable dental utility connector associated with the main body proximate end, the dental utility connector comprising a water supply conduit, an LED power and control conduit, and a disinfection reactor, the disinfection reactor comprising a germicidal UV light source end, a disinfection reactor distal end, and at least one disinfection reactor wall which together with the ends define a confined disinfection reactor inner chamber having a longitudinal axis between the ends, a disinfection reactor fluid inlet on the at least one disinfection reactor wall that receives the dental fluid from the water supply conduit, a disinfection reactor dental fluid outlet on the at least one disinfection reactor wall, and a conduit associated with the dental fluid outlet for delivering dental fluid to the main body proximate end; wherein the germicidal UV light source end directs germicidal UV light toward the disinfection reactor distal end generally along the longitudinal axis of the chamber, such that collimated germicidal UV light substantially irradiates a substantial portion of the disinfection reactor inner chamber to disinfect the dental fluid just prior to being delivered to the point of use relative to the patient, wherein disinfection of fluid occurs while within the disinfection reactor inner chamber after entering into the disinfection reaction inner chamber through the disinfection reactor fluid inlet and before exiting the disinfection reaction inner chamber through the disinfection reactor fluid outlet; wherein fluid from the disinfection reactor fluid outlet is delivered to the main body distal end and out the main body distal end to point of use; and wherein the germicidal UV light source comprises a UV LED.
