The NanovaTM Suture Anchor is comprised of two types: Screw-In and Push-In. Nanova™ Screw-In Suture Anchor is a cannulated, threaded, tapered anchor with integral eyelet for suturing soft tissue to bone. Nanova™ Push-In Suture Anchor is a cannulated anchor with integral evelet for suture soft tissue to bone. In addition the Push-In anchor can use a knotless technique by capturing suture. Suture anchors are preloaded with suture on a handled inserter with a hex driver. The device is made from a copolymer of absorbable 70-30 Poly-L/D-lactide (PLDLA) reinforced with hydroxyapatite. Nanoval Screw-In Suture Anchors are single use, prescription, long term implant, no drug.

The provided document is a 510(k) premarket notification for two medical devices: the Nanova Screw-in Suture Anchor and the Nanova Push-in Suture Anchor. This document focuses on demonstrating substantial equivalence to legally marketed predicate devices rather than proving the device meets specific acceptance criteria through a clinical study.

Therefore, many of the requested categories for acceptance criteria and study details are not applicable or not provided in this type of submission. The information below reflects what can be extracted from the document within the context of a 510(k) submission.

1. A table of acceptance criteria and the reported device performance

For a 510(k) submission, the "acceptance criteria" are generally based on demonstrating "similar performance" to the predicate devices through non-clinical testing. The document states that the mechanical and performance testing resulted in "similar mechanical and performance to the predicate." No specific numerical acceptance criteria or detailed device performance metrics (e.g., in a table with target values) are provided beyond this general statement.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Sample Size for Test Set: This information is not provided in the document. The document mentions "non-clinical performance testing" which includes mechanical and performance testing, but the specific number of units tested is not disclosed.
• Data Provenance: The document does not specify the country of origin of the data or whether the testing was retrospective or prospective. Given it's non-clinical benchtop testing, these distinctions are less relevant than for clinical studies.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This information is not applicable for this 510(k) submission. Ground truth establishment by experts (e.g., radiologists) is typically associated with clinical studies, especially those involving diagnostic devices or image interpretation. This submission focuses on the mechanical and biocompatibility properties of a physical implant (suture anchor), where "ground truth" would be determined by objective measurements and standardized testing protocols, not expert consensus on medical images or patient outcomes.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This information is not applicable for this 510(k) submission. Adjudication methods like 2+1 or 3+1 are used in clinical studies, particularly for subjective assessments or when multiple readers provide conflicting interpretations (e.g., in radiology studies). The non-clinical testing described involves objective mechanical measurements where adjudication by multiple experts is not relevant.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This information is not applicable for this 510(k) submission. MRMC studies, especially those focusing on AI assistance, are relevant for diagnostic devices or software that assist human readers in interpreting medical data. The Nanova Suture Anchor is a physical surgical implant, not a diagnostic or AI-enabled device, so an MRMC study would not be performed for this product.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This information is not applicable for this 510(k) submission. "Standalone performance" refers to the performance of an algorithm or software operating independently without human intervention, which is relevant for AI-powered diagnostic tools. As mentioned, the Nanova Suture Anchor is a physical surgical implant.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

For the non-clinical performance testing, the "ground truth" would be derived from objective measurements obtained through standardized laboratory testing methods and equipment (e.g., force gauges for pullout strength, torque wrenches for insertion torque, etc.). There is no mention of expert consensus, pathology, or outcomes data being used as ground truth for these tests, as they are not clinical studies. The biocompatibility testing followed ISO 10993 standards, where "ground truth" is defined by the results meeting specific criteria or thresholds outlined in those standards.

8. The sample size for the training set

This information is not applicable for this 510(k) submission. "Training set" refers to data used to train machine learning algorithms. The Nanova Suture Anchor is a physical medical device, not an AI or software device that requires a training set.

9. How the ground truth for the training set was established

This information is not applicable for this 510(k) submission, as there is no training set for a physical hardware device.

Nanova™ Flowable Dental Composite is a methacrylate based, low viscosity, visible-light activated, radiopaque, flowable composite. This device is available in syringe and ampule packaging. Nanova™ Flowable Dental Composite is available in a variety of tooth colored shades. Nanova™ Flowable Dental Composite contains methacrylate resins, photo-initiator, and inorganic filler material. Inorganic filler loading is approximately 60% by weight.

When irradiated by light, the methacrylate functionalities of the resins and surface-treated fillers undergo, in conjunction with the photo-initiator system, a light-induced polymerization to form a hard composite that is bonded to the tooth structure with a permanent dental adhesive.

Nanova™ Flowable Dental Composite formulation is based off of several FDA cleared commercially available flowable dental composites. The formulation was modified to improve physical properties, such as flexural strength, and handling properties. As a result of the reformulation, a biocompatibility assessment was developed for Nanova™ Flowable Dental Composite using standard risk assessment techniques and consideration of FDA & internationally recognized guidelines, including ISO 10993 Parts 3, 5, 6, 10 and 11.

The document describes the Nanova™ Flowable Dental Composite, a dental material. The acceptance criteria and supporting studies are detailed, primarily through comparison with a predicate device and non-clinical performance testing.

Here's a breakdown of the requested information:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria for "Nanova™ Flowable Dental Composite" are largely established by demonstrating its substantial equivalence to a legally marketed predicate device (Filtek Supreme Ultra Flowable Restorative K100235) and by meeting established international and ADA standards for dental materials.

Specific quantitative values for performance (e.g., exact flexural strength in MPa) are not provided in this summary, but the document confirms that the device meets or exceeds the standards or predicate device performance for these properties.

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

The document does not specify the sample sizes used for the individual non-clinical performance tests (e.g., number of specimens for flexural strength, depth of cure). It lists the types of tests performed.

The data provenance is from non-clinical benchtop testing performed by Nanova Biomaterials, Inc. and potentially external labs for GLP studies, but specific country of origin for all data is not explicitly stated. The submission is from Nanova Biomaterials, Inc. in Columbia, Missouri, USA. The studies are retrospective as they were conducted to support the 510(k) submission.

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

This information is not applicable as the studies are entirely non-clinical (benchtop and biocompatibility). There is no "ground truth" derived from expert consensus on patient data. The ground truth for performance is the specified standards (e.g., ISO, ADA) and comparison to the predicate device. For biocompatibility, it's defined by the ISO 10993 series.

4. Adjudication Method for the Test Set

This is not applicable as there is no human interpretation or subjective assessment of the test results that would require adjudication in the context of clinical or image-based studies. The results are quantitative measurements against established standards.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This is not applicable. The device is a dental restorative material, not an AI-powered diagnostic or assistive tool. No MRMC study was performed.

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

This is not applicable. The device is a physical dental material, not an algorithm.

7. The Type of Ground Truth Used

The ground truth used for evaluating the Nanova™ Flowable Dental Composite is primarily:

• Established industry standards: ISO 4049:2009 (E) for properties like flexural strength, depth of cure, water sorption/solubility; ADA specification 27 for compressive strength.
• Comparison to a legally marketed predicate device: Filtek Supreme Ultra Flowable Restorative (K100235) for various technical and performance characteristics.
• Biocompatibility standards: ISO 10993 Parts 3, 5, 6, 10 and 11.

There is no pathology, outcomes data, or expert consensus on clinical cases described in this summary for establishing ground truth.

8. The Sample Size for the Training Set

This is not applicable. The device is a physical material, not a machine learning model, therefore there is no "training set."

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

This is not applicable as there is no training set for this type of device.

Ask a specific question about this device

StarBright™ 5% Sodium Fluoride Varnish is a fluoride containing preparation for use as a cavity varnish and for the treatment of dentin hypersensitivity.

StarBright™ 5% Sodium Fluoride Varnish is a rosin based 5% sodium fluoride varnish. This device is available in tray form unit doses of 0.25 and 0.40 mL. Fluoride ions within StarBright™ 5% Sodium Fluoride Varnish may react with calcium and phosphate ions in saliva to form crystals in exposed dentin tubules, such as in exposed root surfaces, leading to protection by blocking external stimuli thereby reducing hypersensitivity.

The provided document is a 510(k) premarket notification for a medical device called "StarBright™ 5% Sodium Fluoride Varnish." This type of submission is for demonstrating substantial equivalence to a legally marketed predicate device, not for proving a device meets specific acceptance criteria based on its performance against quantitative metrics in a clinical study.

Therefore, the document does not contain the information requested regarding acceptance criteria tables, sample sizes for test/training sets, expert ground truth establishment, adjudication methods, MRMC studies, standalone algorithm performance, or detailed ground truth types.

Here's why the information is not present and what the document does contain:

• Type of Device: The device is a "Cavity Varnish" (Product Code: LBH), regulated as Class II. This is a dental material, not an AI/ML-based diagnostic or imaging device.
• Regulatory Pathway (510(k)): The 510(k) pathway for medical devices largely relies on showing that the new device is "substantially equivalent" to a legally marketed predicate device. This typically involves demonstrating similar technological characteristics, intended use, and performance, often through bench testing and biocompatibility. It does not generally require large-scale clinical trials or detailed performance metrics against ground truth, especially for a well-established device type like a fluoride varnish.
• Lack of AI/ML Component: The device is a chemical preparation. It does not involve any artificial intelligence, machine learning, image analysis, or diagnostic algorithms. Therefore, concepts like "test set," "training set," "ground truth experts," "adjudication," "MRMC study," and "standalone algorithm performance" are not applicable to this product.

What the document does include relevant to its regulatory pathway:

• Identified Predicate Devices: The submission identifies several predicate devices (e.g., Duraflor ®, 3M Vanish, Nupro Model 13016901, Enamelast) to which StarBright™ 5% Sodium Fluoride Varnish is considered substantially equivalent.
• Technological Characteristics and Intended Use: It states that the device has the same intended use (cavity varnish, treatment of dentin hypersensitivity) and similar technological characteristics (rosin-based 5% sodium fluoride varnish, paste formulation, unit dose packaging, applied with a brush) as the predicate devices.
• Non-clinical Performance Testing: It mentions that non-clinical performance testing (fluoride release, tubule occlusion, cytotoxicity, sensitization, irritation) was conducted to support substantial equivalence. The document states these tests "demonstrate that the device is as safe, as effective, and performs as well as or better than the legally marketed predicate devices." This is the closest it comes to performance, but it's not quantitative "acceptance criteria" on a diagnostic metric.
• No Clinical Performance Testing: The document explicitly states, "Clinical performance data was not included." This further supports that the type of study design you're asking about (which often involves clinical endpoints or diagnostic accuracy) was not a requirement for this specific 510(k) submission.

In summary, as the input document describes a chemical dental product undergoing a 510(k) review based on substantial equivalence, the requested information pertaining to AI/ML device performance and clinical studies (e.g., MRMC, standalone algorithm performance, expert ground truth) is not applicable or present in this document.
