摘要:
A dental syringe tip having positioned in a material-containing passage therein a plug with a stepped nose configuration to minimize the force required to dispense material from the syringe tip. The stepped nose configuration also increases the amount of material dispensed from the syringe thereby reducing waste. The plug includes a sealing member to provide improved sealing between the plug and the internal surfaces defining the passage within the syringe tip.
