c. Cotton Pliers (FORCEPS, DRESSING). Cotton pliers (figure 1-10) are tong-
like, metallic instruments. The working end of a pair of cotton pliers consists of two
tapered opposing portions that form a 60 degree angle with their handle. Cotton pliers
are used for handling cotton pellets, cotton rolls, small instruments, or other small items
placed into or withdrawn from the mouth. The pliers are also used to carry liquid
medication between the closed beaks for deposit in areas of the mouth or teeth.

d. Periodontal Probes (PROBE, PERIODONTAL). Periodontal probes (figure
1-11) are non-cutting instruments used to determine the depth and outline of soft tissue
pockets. Most are single-ended; some are double-ended. A periodontal probe has a
handle, a rounded nib, and a point (or face). The angle of the nib will vary according to
the intended use. The nib is marked with graduations that correspond to millimeters.
