    This device generates ultrasonic vibrations intended for ultrasonic procedures: 1.) General Supra and Subgingival scaling applications; 2.) Periodontal debridement for non-surgical treatment of Periodontal diseases.

    Device Description

    The Swerv Magnetostrictive Ultrasonic Scaler is a portable stand alone scaler, handpiece and foot control. The Swerv Magnetostrictive Ultrasonic Scaler operates at 25 kHz and accepts voltage inputs between 100-240V. The available power output is segmented into two over zones to assist the user in selecting the recommended power setting for a selected ultrasonic insert. The power and water controls of the Swerv' Scaler are located in the control unit. The Swerv2 Magnetostrictive Ultrasonic Scaler plugs into an ordinary electrical outlet and converts the AC current into high frequency electro-mechanical vibrations. The Swerv3 Scaler features a patented switching mechanism to support the use of either 25 kHz or 30 kHz inserts. Therefore, the scaling system accepts both Hu-Friedy 25 kHz and 30 kHz Ultrasonic Inserts.

    Infection Control Barrier Efficacy: - Viral penetration resistance- Tested and certified to be in compliance for viral penetration in accordance with ASTM F1671.
    Compliance to Standards: - Manufactured to ASTM E1104-98- All of TIDI Products probe cover products (i.e. thermometer sheath, instrument sheaths, and dental camera covers) are manufactured to ASTM E1104-98. (This is a statement about the predicate device, but since the new device is identical, it implies this applies to the new device as well).

    2. Sample Size Used for the Test Set and Data Provenance

    The primary study mentioned is field validation study #604.

    • Sample size used for the test set: Not explicitly stated as a numerical value for patients or devices. The study involved "clinicians" evaluating the device, implying a qualitative assessment by multiple users rather than a statistically defined test set size typical for quantitative performance metrics.
    • Data provenance: Prospective, as it was a field validation study where clinicians evaluated the device. The country of origin for the data is not explicitly stated, but given the submission is to the FDA for a US market device by a US-based company, it can be inferred to be from the US or a region adhering to similar clinical practices.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

    • Number of experts: Not explicitly stated as a specific number. The summary mentions "clinicians" without specifying how many.
    • Qualifications of those experts: "Clinicians" are mentioned, which would typically imply dental professionals or those involved in patient care. No specific qualifications (e.g., years of experience, specialty) are provided.

    4. Adjudication Method for the Test Set

    The field validation study #604 appears to be a qualitative assessment by clinicians. There is no explicit mention of an adjudication method (e.g., 2+1, 3+1 consensus) for the results of this study. The wording "successfully completing a field validation study #604 where clinicians evaluate..." suggests a collective positive outcome rather than a formal, adjudicated reading of results.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done

    No, an MRMC comparative effectiveness study was not done. The primary focus of this submission is demonstrating substantial equivalence to a predicate device and validating basic functional performance through a field study. There is no mention of comparing human readers' performance with and without AI assistance, as AI is not a component of this barrier sleeve device.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done

    No, a standalone (algorithm only) performance study was not done. This device is a passive barrier sleeve, not an algorithm or an AI-powered system, so such a study would not be applicable.

    7. The Type of Ground Truth Used

    For the field validation study #604, the ground truth was expert assessment/consensus (from the clinicians). The criteria evaluated (fit, ease of use, readability, control activation, disposal, tearing resistance, tactile sensitivity) are subjective and based on the practical experience and judgment of the clinicians using the device.

    For the material, biocompatibility, and viral penetration testing, the ground truth was established by standardized testing protocols (e.g., ASTM E1104-98, ISO 10993, ASTM F1671) and their associated pass/fail criteria.

    8. The Sample Size for the Training Set

    Not applicable. This device is not an AI/ML algorithm that requires a training set. The "EI DownPak Barrier Sleeves" are physical accessories.

    9. How the Ground Truth for the Training Set Was Established

    Not applicable. As stated above, this device does not involve a training set.

    Intended Use

    This product is intended for use by dental professionals only. This device generates ultrasonic vibrations intended for use in dental applications such as scaling, periodontal therapy, root canal treatment and cavity preparation.

    Device Description

    The Hu-Friedy® brand Symmetry IQ Ultrasonic Scalers are similar to the Ultrasonic Scalers of the predicate device listed above. These devices are intended for use by dental professionals only. These devices generate ultrasonic vibrations intended for use in dental applications such as scaling, periodontal therapy, root canal treatment and cavity preparation. Hu-Friedy will purchase the generators from NSK, Inc. (Nakanishi) and own brand private label the device. The modifications to the Hu-Friedy product are cosmetic in nature and consist mainly of new shape and design to the housing of the control unit. All of the internal electrical and technical specifications are identical to the marketed NSK units. Hu-Friedy currently has a 510k (K053178) approval for the Symmetry line of piezoelectric tips that are compatible with Satelec and NSK piezoelectric ultrasonic scalers. The addition of the Symmetry IQ generators and handpiece will complete our ultrasonic piezo scaling product line. The Symmetry IQ Ultrasonic Scalers have essentially the same design as the predicate device's ultrasonic generators. The Symmetry IQ 2000 series is equivalent to the Varios 150 Lux (Optic), which is an integrated version of the Varios 350 Lux (Optic) to be used in the delivery tray table as a built in system. The Symmetry IO 3000 series is equivalent to the combination of the Varios 550 control unit with the handpiece used in the Varios 350 Lux (Optic). The Symmetry IQ 3000 unit is based on the NSK Varios 560 which is currently pending FDA 510k approval. The addition of a silicone grip to the ultrasonic generator handpiece used in both models is the only significant change and the reason for the new 510k application.

    AI/ML Overview

    This submission describes the Symmetry IQ Dental Ultrasonic Scaler, a dental device used for various dental applications. The basis of the 510(k) clearance is substantial equivalence to a predicate device, as opposed to a new algorithm-based device requiring extensive performance testing against acceptance criteria.

    Therefore, the requested information regarding acceptance criteria, performance studies, expert involvement, and ground truth for an AI/algorithm-based device is not applicable to this 510(k) submission.

    The document states that:

    • "The modifications to the Hu-Friedy product are cosmetic in nature and consist mainly of new shape and design to the housing of the control unit. All of the internal electrical and technical specifications are identical to the marketed NSK units."
    • "The Symmetry IQ Ultrasonic Scalers have essentially the same design as the predicate device's ultrasonic generators."
    • The "addition of a silicone grip to the ultrasonic generator handpiece used in both models is the only significant change and the reason for the new 510k application."

    The studies mentioned (sterilization study, biocompatibility testing, ISO 22374 life testing) are safety and performance verification tests for the modified components and overall device, rather than comparative effectiveness studies for an AI-driven diagnostic or therapeutic tool.

    As such, I cannot populate the table and answer the specific detailed questions as they are designed for performance evaluation of AI/ML software or algorithms, which is not the nature of this device's submission.
