Which instrument from the list is a type of plier?

• A. Mathieu pliers
• B. Band seater
• C. Ligature tucker
• D. Mosquito forceps

Answer: (A)

Pliers are hand-held gripping tools with two handles that pivot to close a jaw for bending, shaping, or holding metal. The name Mathieu pliers identifies them as a plier type because they are specifically designed for gripping and manipulating metalwork in dental work, such as bending wires or forming bands. The other instruments have different roles: a band seater is used to seat orthodontic bands on teeth, a ligature tucker is used to tuck ligatures in place, and mosquito forceps are small grasping forceps used for tissue or small items rather than as pliers. So the instrument that is truly a plier is the Mathieu pliers.
