Question

Which separators are placed between contacts with a "sawing" or flossing motion?

1) Brass wire
2) Elastomeric
3) Steel spring
4) Wedge

Answer 1

Elastomeric separators are used in dentistry to create space between teeth and are placed with a sawing or flossing motion. Other separators like brass wire, steel spring, and wedges are used differently.

Step-by-step explanation:

Separators are used in dentistry to create space between teeth before the placement of orthodontic bands. The type of separator that is placed between contacts with a "sawing" or flossing motion is the elastomeric separator. These are made of elastic material and can be inserted into the interproximal spaces of teeth using a flossing-like action. They slowly push the teeth apart to create enough space, usually for the bands to fit properly during orthodontic treatment. Brass wire, steel spring, and wedge are other forms of separators; however, they are typically used for different applications and might be placed using other techniques.
