Curettage involves the removal of plaque, calculus, and pigmentation from the crown and from root surfaces of the teeth as well as any cement on the root surfaces, in order to reveal a smooth, hard, and clean surface.
It is a clinical procedure that must be performed with local infiltrative anesthesia and, depending on the location of the calculus and the depth of the periodontal sac, it can be performed in a number of different ways, such as open curettage, closed curettage and maintenance curettage. p>
