Intended Use
The ultrasonic scaler tips are intended for use by dental professionals to: 1. Remove supra and sub gingival calculus deposits and stain from the teeth; 2. Clean and irrigate root canals.
Device Story
Ultrasonic scaler tips function as accessories to piezoelectric ultrasonic handpieces and scaler units. Tips attach to handpieces via M3x0.6 internal thread; vibrate at ultrasonic frequencies (23kHz-33kHz) to remove calculus deposits, stain, and perform endodontic root canal cleaning/irrigation. Used by dental professionals in clinical settings. Output is mechanical vibration applied directly to tooth surfaces or root canals. Benefits include efficient removal of dental deposits and effective root canal preparation. Device is provided non-sterile and requires steam sterilization by the user.
Clinical Evidence
No clinical data. Substantial equivalence supported by bench performance testing, including biocompatibility (cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity), reprocessing validation (ISO 17665-1), and mechanical performance testing per ISO 18397 and ISO 3630-5.
Technological Characteristics
Materials: Stainless Steel 30Cr13 and Nickel Titanium Alloy. Energy: Piezoelectric ultrasonic vibration (23kHz-33kHz). Form factor: Tips with M3x0.6 internal thread. Sterilization: Steam sterilization (132°C for 4 minutes). Connectivity: Mechanical attachment to compatible piezo-electric dental scalers.
Indications for Use
Indicated for dental professionals to remove supra and sub gingival calculus and stain from teeth, and to clean and irrigate root canals.
Regulatory Classification
Identification
An ultrasonic scaler is a device intended for use during dental cleaning and periodontal (gum) therapy to remove calculus deposits from teeth by application of an ultrasonic vibrating scaler tip to the teeth.

Dear Alice Yang:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrb/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
