The cleaning of dental calculus mainly relies on ultrasonic scaler, ultrasonic supragingival cleaning, the cleaning process includes cleaning and polishing.
1. Cleaning: adjust the appropriate vibration frequency according to the thickness of the tartar when cleaning, to avoid direct contact with the tooth surface of the working head causing damage to the tooth surface. The front part of the working head is gently moved back and forth in parallel with the tooth surface or at an angle of <15° in contact with the underside of the tartar, using ultrasonic vibration to break up and vibrate down the tartar.
Scaling should be carefully checked with a probe after the completion of any omissions, for some small or neighboring surface of the tartar should be hand-operated instruments to supplement the scraping.
2. Polishing: The commonly used polishing equipment is rubber cup polishing. Through the rubber cup dipped in polishing paste low-speed rotation polishing tooth surface, so that the surface of the tooth is smooth without scars, plaque and tartar will not be easy to build up again.
When there is a need to clean the calculus, it is recommended to go to a regular dental hospital for cleaning, to avoid irregular operation damage to the dental tissues.
