The jet (36) may comprise medical grade saline, disinfectant, antibiotic or abrasive solutions. All the soft tissue within t he tooth (10) is cut, excised, emulsified, and aspirated out of the tooth (10).  The time required to excise, emulsify, and aspirate all the soft tissue with in a typical molar is on the order of 10 seconds to 240 seconds. The interior chamber (26) of the tooth (20) is completely aspirated, verified visually fo r completion of removal of all soft tissue, and then packed with an appropriat e filler material. The opening (32) in the top of the tooth (10) is filled or provided with a prosthetic crown. The fluid jet (36) may comprise a pulsed j et formed by a pulse intensifier device in the handpiece (33) of the dental hyd ro- jet tool (35), or steady stream jet emanating from the orifice.

Inventor: WILLIAMS KELLY F
IPC: B65H37/00
Filed: 2002-07-05
Abstract: A slip-sheet compactor for an imaging device with automatic media handling capabilities provides a two-stage compaction for a slip-sheet removed from a media sheet to be imaged. A pair of rollers advances the slip-sheet into a pre-compression chamber effecting a first compression or folding operation. In a second compression, a plunger sweeps the pre-compression cavity, which is narrowed towards an exit slot thus effecting a second compression on the slip-sheet material.      By performing individual compaction on each removed slip-sheet, the possibility of blockages or jams is reduced.
