Ultrasonic Scaler is used to remove dental plaque from teeth and remove stains on teeth during dental cleaning.
A device intended for use during dental cleaning and periodontal (gum) therapy to remove adherent plaque and food debris from the teeth to reduce tooth decay, potential stains in the gingival groove, the back of the tooth and the tooth and associated gingival line. The electronic oscillation circuit generates ultrasonic frequency electric pulse wave, which is amplified to a certain intensity and conveyed to the transducer. The electrical energy is converted into mechanical energy, and the working head tool is stimulated to produce vibration of the same frequency, so as to achieve the purpose of crushing calculus and loosening tartar.
The provided text is a 510(k) summary for an Ultrasonic Scaler (K240707). It describes the device's substantial equivalence to a predicate device and outlines performance data. However, it does not contain the acceptance criteria or a study that proves the device meets those criteria in the context of AI/ML performance.
Instead, the document focuses on:
- Comparison of technological characteristics between the proposed device and a predicate device (K163414). This comparison highlights similarities and differences in design, operation controls, power supply, operating conditions, storage conditions, and electrical/EMC/biocompatibility standards.
- Performance data limited to biocompatibility testing and non-clinical testing of electrical safety and electromagnetic compatibility (EMC) according to various IEC standards.
Therefore, I cannot provide the requested information regarding acceptance criteria for an AI/ML device, its reported performance, sample sizes, ground truth establishment, or specific AI/ML study details, because this information is not present in the provided document.
The document discusses acceptance criteria and performance data for a physical medical device (ultrasonic scaler), not an AI/ML component.
If this was a misunderstanding and you were expecting information related to a traditional medical device's performance, please clarify. Otherwise, the requested AI/ML specific information is absent from this document.

Dear Fengmeng Han:
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/cdrh/cfdocs/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.
