Abstract: Dental matrix band devices including a housing with a band, a tensioning device for the band with the control for the tensioning mechanism controllable by a control knob external to the housing, and at least one deflector pushbutton. The deflector pushbutton(s) applies pressure on an upper or lower portion of the band causing the geometry of the band to change. The resulting band geometry forms a conical loop better matching the configuration of a tooth. In one embodiment two deflector pushbuttons are provided and positioned to apply pressure on the upper or lower portion of the band depending on which deflector pushbutton is depressed in the housing. In another embodiment a single deflector pushbutton unit is provided with a pushbutton at each end.

Abstract: A spindle assembly for supporting a web material roll in a web material dispenser, the web material roll having first and second extremities and defining a central cavity provided with a bushing toward the first extremity. The spindle assembly includes a bushing-engaging member having: a first dispenser mounting portion mountable to a first side of the dispenser, and a bushing-engaging portion sized and configured to fit at least partially in the bushing; and a spindle connection member having: a second dispenser mounting portion mountable to a second side of the dispenser, and a connecting portion removably mountable to the bushing-engaging member; thereby allowing use of the roll with the bushing in the dispenser. Also, a roll dispensing assembly and a method for inserting a roll of web material in a dispenser.
