The term curettage is used in periodontics to mean the scraping of gingival wall of a periodontal pocket to separate diseased soft tissue. Whereas scaling refers to removal of deposits from tooth/root surface and root planning; means smoothening the root to remove infected and necrotic tooth surface. This chapter covers the types, rationale, indications, procedure, healing after scaling and curettage, clinical appearance after scaling and curettage, and current concept. The main accomplishment of curettage is the removal of chronically inflamed granulation tissue that forms in the lateral wall of the periodontal pocket. Indications for curettage are very limited and can be used after scaling and root planing. Curettage can also be performed with the help of chemicals and ultrasonic scalers.
