What are periodontal dental instruments?

Periodontal instruments are hand tools used to remove subgingival deposits, perform root planing, and assess periodontal health. The category includes Gracey curettes (paired site-specific designs 1/2 through 17/18), Columbia curettes, sickle scalers (H6/H7, S204S, Jacquette), universal curettes, and periodontal probes (Williams 1-2-3-5-7-8-9-10, UNC-15, WHO ball-tip). Hollow-handle and rigid-shank variants serve scaling versus root-planing applications respectively.
