Document Summary
Describe the 3 rules for determining the correct working end of a curet: toe pointed in the direction you are scaling (m or d) Angulation is decreased/closed by tilting blade toward tooth. Use modified pen grasp and establish a fulcrum. 0 deg insertion to have smooth insertion and to not cut gingiva. Increase angulation by tilting lower shank away from the tooth. Once inserted, open to 45-90 deg: describe methods for adapting the curet blade to remove calculus. Roll the wrist and keep 1/3 of the blade on the tooth: describe methods for activating exploratory strokes and scaling/working strokes. Push and pull strokes, usually with forearm. Vertical (mesial, distal surfaces), horizontal (selectively at line angles and deep pockets) extreme caution with horizontal, oblique (circumferentially) Calculus forms in horizontal rings so v and o strokes are directed at right angles toward calc. When calc felt, muscles of fingers and hands are firm and firm lateral pressure applied.
