SFMS Dental Practice Exam

Dental instrument #150 is commonly known as a universal forceps. This instrument is specifically designed for the extraction of both maxillary (upper) anterior teeth and can also be used for premolars. Its design features curved beaks that ensure a good grip on the tooth, allowing for effective traction during an extraction.

Universal forceps are versatile tools that a dental practitioner can use for a variety of tooth extractions, which contributes to their designation as "universal." This adaptability makes them a staple in dental practices, accommodating different tooth positions and roots found in patients.

In contrast, other instruments listed have specific functions: maxillary forceps are used primarily for upper molar extractions, an X-ray holder is used for positioning radiographic films or sensors, and a curette is utilized for scaling and root planing in periodontal treatments. Understanding the specific function and application of these instruments is essential for effective dental practice and patient care.
