A curette is a surgical instrument designed for scraping biological tissue or debris in a biopsy, excision, or cleaning procedure. In form, the curette is a small hand tool, often similar in shape to a stylus; at the tip of the curette is a small scoop, hook, or gouge.
Uses of Curette
Surgeons often use a curette for the debridement of tissue, a common example of which is dilation and curettage of the uterus performed in gynecology.
In the performance of an adenoidectomy, an otolaryngologist may view the adenoids using a mirror or endoscope, and then excise the adenoids with a curette.
In periodontology, the edged hook of the periodontal curette scrapes calculus (tartar) deposits from tooth enamel.
