The Milton Syringe was essentially a miniature syringe.

The critical factor in the accuracy of a syringe is the internal diameter.

Each time you reduce the diameter by half, you increase the required plunger travel AND the accuracy by four.

Each millimeter of travel of the Milton Syringe produces 0.0009cc of cement.

Since we have the capability of moving the plunger in tenth of millimeter increments, the accuracy is plus or minus 0.00009cc.

As you can imagine, it would take forever to fill a canal at this rate, so the Milton is used to seal the apex, under pressure and then back filling is done with either the Precision Endo Syringe, the Precision Multi_Mode Syringe or the newest Precision Endo Obturating Cartridge Syringe.

The "Milton Syringe" has now been relegated to research status.

A new syringe incorporating an actual micrometer is now available that exceeds the capabilities of the "Milton" in that it is possible to move the plunger as little as 0.00025 inches and thus with the 0.119 inch diameter of the cement cartridge, deliver cement with such control that we can actually now predetermine the SIZE of the puff.
