Parkell Sensimatic Electrosurgery Electrodes, 1/16" Shaft · T-2 Scalpel Point

• Scaler Units — The unit that generates the vibration, as against the tips and accessories that fit it. A rotary scaler does the same job differently: it is an abrasive device attached to a powered handpiece to remove calculus deposits, also Class II (21 CFR 872.4840).
• Scaler Tips & Inserts — The part that is changed, matched to one of the two categories of ultrasonic scaler.
• Scaler Accessories — Carries water, air or the tip to the unit; it is not the working end itself.
• Electrosurgery Units — Cuts and coagulates soft tissue with current, where a scaler removes calculus from teeth with vibration.
• Electrosurgery Accessories — The electrode that carries the current into the tissue, not the generator behind it.
• Air Polishing Units — Cleans with a powder-and-water jet rather than with a vibrating tip. Powder jet handpieces sit outside the scope of ISO 14457, the standard for dental handpieces and motors, as do air-powered and electrical-powered scalers.
• General Repair & Replacement Parts — A worn part swapped for the same part, not a tip consumed in treatment.
• Handpiece Parts Accessories & Maintenance — Belongs to the handpiece that carries the tip, not to the generator or the tip itself.
• Filters — Treats the water going into the scaler rather than touching the tooth.
• Hoses Tubing & Fittings — Carries water and air to the handpiece; the filter in the same line treats what passes through it.

Two pages here also carry a hand-instrument scaler tag although the products are piezo tips; that type belongs to the periodontal instruments shelf.

Scaler type: the tips are made for one category or the other, and the two differ in frequency as well as in tip movement. In a clinical study patients reported more pain, noise and vibration from magnetostrictive scalers than from piezoelectric ones, which the authors attribute to the different tip movements.

Power: low power is recommended in order to reduce discomfort and loss of hard tissue, and a narrative review found a positive correlation between power setting and surface alteration.

Implanted cardiac devices: the ADA reports that piezoelectric dental scalers may be safer than magnetostrictive models, and that electrosurgery devices have the highest potential for electromagnetic interference. In-vitro studies have consistently shown clinically significant interference from monopolar electrosurgery, including pacing interruptions.

Powder for an air polisher: sodium bicarbonate is effective on supragingival plaque and stains but is highly abrasive to root cementum, dentin and restoration surfaces. Glycine is approximately 80 percent less abrasive than sodium bicarbonate, and erythritol has a particle size similar to or smaller than glycine. A narrative review of periodontal instrumentation described air-polishing systems as less abrasive, particularly in biofilm management.

Polishing powder is its own FDA class: an oral cavity abrasive polishing agent, a paste or powder containing an abrasive material intended to remove debris from the teeth and applied by a handpiece attachment, Class I under 21 CFR 872.6030.
