A dental capsule for mixing a cement powder with an activating liquid having a frangible seal. The frangible seal is placed between a nozzle and the body portion of a capsule preventing unmixed cement from entering the nozzle. The nozzle has a circumferential groove facilitating positioning thereof. A vent formed in the body of the capsule prevents premature rupturing of the frangible seal upon insertion of the plug. A second and third embodiment use a two-part plug for dispensing activating liquid to the cement powder contained within the body of the capsule. |
