DenTek Temparin Precision
The DenTek Temparin Precision is a penlike device for dispensing temporary filling material into teeth. You are supposed to remove the tip and then click the handle to dispense the temporary filling paste into a cavity. Then, you are supposed to replace the cap and use it to compact the paste into the cavity.
Good aspects of the design:
- The clicking handle dispenses paste with an audible and tangible click, providing excellent feedback to the user.
Usability flaws:
- The cap is difficult to replace after paste has been dispensed for the first time. Some of the paste remains in the way, so the cap can only be replaced loosely; it becomes prone to falling off.
- Using the cap to compact temporary filling paste into a cavity is practically impossible. The cap falls off into your mouth every time.
- The cap is small, unattached, and easy to swallow accidentally while trying to compact the filling material.
- Without the cap, the dispenser tip provides no real aid in dispensing the filling material. It is easier to dispense the temporary filling paste onto a finger and then push it onto a tooth, than to use the dispenser as intended.
In other words, the only good aspect of the design is the clicking handle. Most of the design features make the device difficult or impossible to use as intended. It is easier to use just the temporary filling material without the dispensing device, making this product essentially frivolous.
