Abstract: The invention discloses a pen-shaped micro-dispensing applicator for calcium hydroxide liners such as Dycal. The device comprises two separate chambers containing base paste and catalyst paste, a plunger-actuated delivery system, finger rests for ergonomic operation, a sliding lock ring for storage and dose control, a Y-shaped mixing junction, a transparent static micro-mixer containing a spiral mixing element, and a flexible bendable cannula tip for direct placement into deep cavities.
