H5/33 Sickle Scaler Instrument

The H5/33 Sickle Scaler Instrument is a double-ended dental scaling tool. It pairs a stainless-steel body with a violet-colored resin handle that measures 10 mm in diameter. The handle surface carries a raised dot pattern for a secure, non-slip grip. Both working ends come from German-grade stainless steel. Each end has a triangular cross-section with two sharp cutting edges tapering to a pointed tip. The total instrument length is approximately 18.5 cm, and it weighs around 28 grams.

The H5/33 DE Scaler carries two distinct working ends on a single handle. The H5 end has a straight, moderate shank with a curved blade for anterior tooth surfaces. The 33 end features an angled shank that bends away from the handle axis to reach posterior quadrants. The violet color of the handle allows quick identification on a dental tray without searching through instruments. Both tips retain their cutting edge through repeated autoclave sterilization cycles without warping.

Dental hygienists and periodontists use the H5/33 Sickle Scaler Instrument during supragingival scaling procedures. These include routine prophylaxis visits, periodontal maintenance, and initial debridement appointments. The H5 end removes calculus deposits from the labial and lingual surfaces of anterior teeth. The 33 end targets the buccal and lingual surfaces of premolars and molars. The H5-33 Sickle Scaler also sees use in pre-surgical site preparation before periodontal flap surgery.

Leader Surgical manufactures this instrument to dimensional standards that dental teams rely on across daily clinical use. The violet resin handle and dual working-end design work well in high-volume practices. Durable stainless-steel tips handle repeated sterilization without shape loss. The dot-pattern grip reduces hand fatigue during extended scaling sessions. Every geometric detail of this scaler reflects direct input from practicing clinicians.

What is the H5/33’s primary clinical role?
It is a non-paired anterior scaler designed for the removal of supragingival calculus (tartar above the gum line). The H5 end is a straight sickle for anterior surfaces, while the Jacquette 33 end is a curved sickle for reaching tight interproximal spaces.
