Dental product

A dental product comprising:

• (i) a dispensing container with an upper and a lower body which are telescopically engageable one with another, the upper body including at least two hollow and separate parallel cylinders, the cylinders having a first generally closed end and a second end telescopically and slidingly accommodating at least two parallel pistons which conform to ride sealingly along the interior walls of the cylinders so as to force any flowable materials to flow toward the first end of the cylinder upon relative compression of the cylinders and pistons, the cylinders having outlet channels;
• (ii) an outlet means in fluid communication with the outlet channels, the outlet means including adjacent outlet openings unconnected to each other and having means for causing the flowable materials to flow toward each other at the outlet openings to form a single, banded, unmixed stream;
• (iii) a first semi-solid flowable material and a second semi-solid flowable material, the second semi-solid material containing a bicarbonate salt, each of the first and second semi-solid materials being stored in separate ones of the at least two hollow parallel cylinders, and at least one of the semi-solid materials containing from 0.05 to 20% of a polyphosphate.
