Periodontal scaler

（重定向自Dental scaler）

A posterior scaler shown in relation to a posterior tooth on a typodont.

The anterior scaler (yellow ring) is straight, while the posterior scaler (orange ring) has an angled terminal shank (highlighted in red) to allow for easy access to the surfaces of posterior teeth.

Periodontal scalers are dental instruments used in the prophylactic and periodontal care of teeth (most often human teeth), including scaling and root planing. The working ends come in a variety of shapes and sizes, but they are always narrow at the tip, so as to allow for access to narrow embrasure spaces between teeth. They differ from periodontal curettes, which possess a blunt tip.
