Do Universal curettes have two cutting edges?
DESIGN FEATURES. The working end of a universal curet consists of two straight parallel cutting edges that join to form a rounded toe. The face of the blade is at a 90° angle to the shank, and both cutting edges are used to remove calculus and debride the root surface.
What are the different types of curettes?
There are two categories of periodontal curettes: universal curettes and Gracey curettes. A universal curette is designed to adapt to all teeth surfaces in all areas of the mouth. A Gracey curette, also called area-specific curette, adapts to a precise area of the teeth.

(Dilatation and Curettage, D&C) A dilation and curettage procedure, also called a D&C, is a surgical procedure in which the cervix (lower, narrow part of the uterus) is dilated (expanded) so that the uterine lining (endometrium) can be scraped with a curette (spoon-shaped instrument) to remove abnormal tissues.
What is a Gracey 17 18 used for?
The 17/18 Gracey Curette is designed to improve access to the distal surfaces of posterior teeth (Figure 15). The deep angle of the shank, along with multiple bends, provides crown clearance and prevents interference of the handle with the opposing arch and teeth.
