Scaler Currettes Anterior & Posterior Sickle

A scaler curette is not a standard standalone instrument name — it's a general term people sometimes use when referring to scalers and curettes, which are two distinct but related types of periodontal instruments used for cleaning teeth.

GROUP 1: Anterior Sickle Scalers

Used for supragingival cleaning on front (anterior) teeth. Thin, straight, or slightly curved.

1. 1Y1-1YS
2. H6-7
3. H5-33
4. U15-30

GROUP 2: Posterior Sickle Scalers

Used for supragingival cleaning on back (posterior) teeth. Curved and short blades for tight spaces.

1. 204S
2. U15-33
3. 2Y-3Y

Here’s the difference:

Scaler

• Sharp, pointed tip
• Used to remove supragingival calculus (above the gumline)
• Types: Sickle scaler, Jacquette scaler
• Typically two cutting edges with a triangular cross-section
• Used with a pulling motion

Curette

• Rounded toe and back
• Used to remove subgingival calculus (below the gumline) and for root planing
• Types:
  • Universal curettes (e.g., Columbia 13/14 – both edges work)
  • Gracey curettes (area-specific, one working edge)
• Semi-circular cross-section – less tissue trauma
