    摘要: A dental apparatus provides a substantially uniform concentration of abrasive material entrained in a pressurized gas to a desired location substantially irrespective the amount of abrasive material in a pressurized container of the apparatus, and resists clogging by the abrasive material. The apparatus includes a control unit having a container (26) that secures the abrasive material (80), the abrasive material in the container becoming entrained in pressurized gas received from a dental unit. The concentration of the mixture of entrained abrasive material in pressurized gas is maintained by upwardly directing the flow of the mixture (88) in a first conduit against a cap (74), a portion (90) of the entrained abrasive material returning to the container, with the regulated mixture (92) of entrained abrasive material in pressurized gas being delivered through a hand piece to the desired location.

    摘要: A syringe sleeve (10) receives a syringe (11) without the syringe (10) dispensing tip (12). After the syringe (11) is received within the sleeve (10), the dispensing tip (12) is affixed to the syringe (11). This causes the end (50) of the sleeve (10) to open and the end (50) to be physically impinged between the tip (12) and the syringe (11). The syringe (11) is thus protected from the operative environment.

    摘要: A dental syringe (10) has a needle (11) affixed to a carpule holder (12), which carpule holder (12) is affixed to a power drive unit (13). A harpoon (20) is provided to affix the drive unit to the carpule plunger (32). The harpoon (20) is made of stainless steel or other hard, corrosion resistant, sterilizable, material. Harpoon (20) has a unique barb geometry and hardened, knife-like edges (21). The syringe (10) may operate to divide the delivery of anesthesia into two phases. According to the method, during the first about 10 seconds of the injection, anesthetic is delivered at an extremely slow rate to maximize patient comfort. The injection rate then automatically increases to the preprogrammed rate associated with the injection type selected.
