Abstract: An apparatus allowing the provision of light and/or water at the tip of a dental illumination light curing device normally provided without such capability includes a pair of supply lines terminating at their remote end in an adapter capable of connection to a standard air/water connection as found on a dental pedestal. The local ends of the supply lines terminate at the neck of the illuminator, where they are supported upon the neck by a clamp, and interconnect with a pair of nozzle tubes. The nozzle tubes have exits at the illuminator tip, and are secured thereto in a removable manner. The modular nature of the apparatus allows removal and exchange of the nozzle elements as desired to accommodate differing illuminator neck shapes and lengths and permit sterilization and replacement of the nozzle elements.

Abstract: An apparatus for assisting in the positioning of a dental X-ray generating unit for the creation of an X-ray image of an internal target portion of the mouth separated from the X-ray generating unit by a soft-tissue facial portion is composed of a substantially X-ray-transparent body adapted to be mounted in the path of the X-rays between the X-ray generating unti and the film element and an illumination source mounted to the body. The body has an outwardly-directed face positioned essentially perpendicular to the X-ray path and facing the soft-tissue facial portion between the X-ray source and target. The illumination source is positioned to direct at least one beam of light perpendicular to and outwardly from the body face towards the facial feature along the path of the X-rays generated by the generating unit to produce at least one light spot on the facial feature to serve as an orientation means for said X-ray unit.
