30/33 Jacquette Scaler

The 30/33 Jacquette Scaler is a double-ended anterior sickle scaling instrument constructed from surgical-grade stainless steel, combining two distinctly sized straight sickle blades — the figure 30 end carries a standard-width blade, while the figure 33 end features a narrower miniature blade. Both working ends carry two sharp cutting edges on a straight blade that taper to a pointed tip with a triangular cross-section — the defining geometry of the Jacquette scaler pattern. The straight, non-angled shank on each end positions the blade for direct anterior tooth access without the contra-angle geometry found on posterior sickle variants. The vivid cyan silicone dot-grip handle stands out clearly on any tray, providing a secure hold throughout active scaling strokes.

The two different blade widths on a single instrument give the 30/33 Jacquette Sickle Scaler a dual-function capability — the standard 30 end addresses broader anterior surfaces and heavier deposits, while the miniature 33 end targets the tightest interproximal spaces between crowded anterior teeth. Both blades maintain sharpness through the instrument’s rigid shank construction, which transmits direct pull-stroke force without flex deflection.

Dental hygienists use the 30/33 Jacquette Scaler during prophylaxis appointments to remove supragingival calculus from the labial, lingual, and interproximal surfaces of mandibular and maxillary anterior teeth. The clinician adapts the blade tip against the tooth at 70-to-80 degrees, establishes an intraoral anterior fulcrum, and activates short 2-to-3mm vertical or oblique pull strokes until calculus fractures free from the enamel surface.

The Jacquette Scaler 30/33 remains a foundational anterior hygiene instrument in clinical practice. Leader Surgical produces this scaler to consistent blade geometry, verified stainless steel composition, and a sterilization-safe cyan silicone handle coating.
