What distinguishes a Jaquette scaler?

A Jaquette scaler is specifically designed as a hand instrument for the removal of calculus and plaque from the surfaces of teeth. Its design typically features a pointed tip that allows dental professionals to effectively access and clean areas such as the proximal surfaces of teeth where calculus tends to accumulate. This scaling action is crucial for maintaining periodontal health and preventing gum disease.

The other options point to different uses of dental instruments. For instance, orthodontic adjustments involve different specialized tools, surgical incisions require instruments designed for cutting tissue rather than scaling teeth, and aesthetic procedures often utilize instruments tailored for cosmetic outcomes, rather than for cleaning. Thus, the main distinguishing feature of the Jaquette scaler is its role as a hand instrument specifically intended for the removal of calculus.
