When passing and root canal filling dentists require a specific group of instruments. The representative of this group is a dental root spreader designed for lateral condensation (compaction) of gutta-percha pins.
Lateral (lateral) procedure obturation (filling) with gutta-percha pins involves the introduction of gutta-percha pins (small pointed sticks) and their condensation (compaction) in the canals of the tooth. For high-quality condensation, the pins need to be made plastic. This effect is achieved by warming up the pointed end of the spreader and pressing the pins against the tooth wall with it.
Tool description
Tool characteristics:
- working part material - stainless steel;
- handle material - stainless steel or medical plastic;
- the shape of the working part is one-sided, conical, with a pointed, curved end and smooth walls.

Difference from other instruments in this group
This group of tools also includes a pluger (vertical seal 
gutta-percha) and condensers (machine tools for filling root canals).
The characteristic difference between a spreader and a pluger is its function. The plug is used to perform vertical condensation, that is, in the root canal, it performs up and down movements. The spreader is pressed against the walls of the gutta-percha (horizontal movements are carried out).
Condensers are not separate instruments, but handpieces for dental burs.
There are also more advanced tools that heat up on their own.
