Designed for removal of light to moderate supragingival calculus from the lingual surfaces of mandibular anterior teeth and interproximal embrasures. The 204S sickle tip adapts to the curved incisal edges of lower centrals and laterals during prophylaxis appointments. Its sharp cutting edge shears hardened plaque without requiring excessive lateral pressure on delicate gingival margins.

Employed for subgingival root planing on specific tooth surfaces where the Gracey angulation matches the root concavity, typically mesial or distal aspects of premolars and molars. The offset blade reaches 4–6 mm below the gingival margin to debride cementum affected by moderate periodontitis. Clinicians use each Gracey number to instrument only one-third of the tooth circumference per appointment.

Used during routine prophylaxis to remove supragingival stain and calculus from buccal and facial surfaces of all dentition. The hygienist scaler’s balanced design supports fulcrum stability when scaling the maxillary molars from the palatal approach. It is well suited for maintenance patients with generalized gingivitis who require thorough coronal polishing after debridement.

Applied when encountering tenacious subgingival and supragingival deposits on teeth with heavy tobacco staining or long-standing neglect. The Super Taha scaler’s robust shank transmits controlled force to fracture calcified ledges on the cementoenamel junction of posterior teeth. Periodontal therapists select this instrument during initial phase therapy for patients with advanced calculus formation.
