ultrasonic scaler

Also found in: Dictionary, Thesaurus, Encyclopedia.


a dental instrument for removal of plaque, bacterial endotoxins, and calculus from teeth.
Scaler. From Dorland's, 2000.
ultrasonic scaler an ultrasonic instrument with a tip for supplying high-frequency vibrations, used to remove plaque and calculus from teeth and bits of inflamed tissue from the walls of the gingival crevice.

ul·tra·son·ic sca·ler

an ultrasonic instrument that uses high frequency vibration to remove adherent deposits from the teeth.

ultrasonic scaler

a vibrating crystal-driven high frequency (18 to 50 kHz) instrument with a tip for supplying high-frequency vibrations which produces bubbles that form and collapse, allowing the removal of adherent deposits such as bacteria, biofilm, calculus, and other root surface accretions from the teeth. The water stream washes the gingival pocket and the root surfaces to dilute and remove endotoxins along with bits of inflamed tissue from the walls of the gingival crevice and loose debris. See also hand scaling, sonic scaler.

ul·tra·son·ic scal·er

(ŭltră-sonik skālĕr)
An ultrasonic instrument that uses high frequency vibration to remove adherent deposits from the teeth.

mag·ne·to·stric·tive ul·tra·son·ic de·vice

(mag-nē'tō-strik'tiv ŭl'tră-son'ik dĕ-vīs')
Electronically powered tool that used rapid energy vibrations of a powered instrument tip to fracture calculus from tooth surfaces and cleanse environment of a periodontal pocket; consists of a portable unit that contains an electronic generator, a handpiece, and interchangeable instrument inserts.
Synonym(s): ultrasonic scaler.


a manual or mechanical instrument used to remove deposits from the surface of teeth. See also tartar scraper.

rotosonic scaler
an air-driven scaler with a rotating bur.
subsonic scaler
one with a tip that vibrates less than 20,000 cycles per minute.
ultrasonic scaler
the scaling tip, which vibrates at high frequency, is cooled by water. There are several types, including magnetostrictive and piezoelectric, which differ in the mechanisms producing the vibrations. Cleaning occurs by cavitation. See also ultrasonic cleaning.
