Abstract: A dental handpiece especially for transmitting intense light for use in polymerizing dental materials in situ has a readily removable opaque shield of deformable material affixed to the end thereof to preclude the light from spreading and to prevent inadvertent contact of the handpiece tip with the subjacent area.

Abstract: An apparatus for treating the surface of a dental inlay for a tooth has a cup enclosure with a restricted opening therein. A hollow stem is slidably received in the cup and releasably held in a chosen position. An inlay holder is at the end of the stem within the cup enclosure and in the path of a stream of grit particles projected from the reservoir through a nozzle extending through the opening into proximity with the inlay holder.

Abstract: A dental dam clamp in each of two lateral wings has an aperture at least partially bounded by several arcuate walls to engage a handling tool in any of several different positions.

Abstract: A dental wedge system has two interfitting circular-bodied wedges adapted to extend between adjacent teeth and to abut and hold a matrix disposed around one of the teeth.

Abstract: An interdental stimulator for use with human teeth in situ is formed of a stick of clear wood, preferably European sycamore, elongated in the direction of the wood grain and for the most part being substantially rectangular in transverse cross-section. One end portion of the stick is conformed to define two mutually inclined, longitudinally extending, approximately planar side surfaces. This end portion is substantially triangular in transverse cross-section and is truncated to form an inclined planar surface opposite the apex or ridge of the triangular portion. The end portion in transverse cross-section is of a size to be at least partly received in the normal interproximal spaces between human teeth.
