Device Description

CLEARFIL SA CEMENT is a dual-cure (light-and/or self-adhesive resin cement for conventional porcclain, ceramic, hybrid ceramics (e.g. ESTENIA C&B), composite resin and metal restorations. It is classified into dental cement (21 CFR section 872.3275, Product code: EMA ) according to 21 CFR § 872 since it is composed of various materials other than zinc oxide-eugenol. According to the applicable FDA recognized consensus standard, ISO 4049: 2000 "Dentistry - Polymer-based filling, restorative and luting materials", this device is classified into the following: Class 3: materials that are cured by the application of external energy and also have a self-curing mechanism present

AI/ML Overview

Here's the analysis of the provided text regarding the acceptance criteria and study for the device:

Device: CLEARFIL SA CEMENT (Dental adhesive resin cement)
510(k) Number: K081583

This submission focuses on demonstrating substantial equivalence to predicate devices, rather than an independent clinical study to establish acceptance criteria for novel performance claims. Therefore, the "acceptance criteria" discussed here are primarily compliance with an existing standard and comparative performance to predicates.


Acceptance Criteria and Reported Device Performance

CriteriaReported Device Performance
1. Compliance with ISO 4049: 2000 "Dentistry - Polymer-based filling, restorative and luting materials" (specifically for Class 3 materials: dual-cure)Verified: The device has been "verified to comply with the requirements of the applicable FDA recognized consensus standard, ISO 4049: 2000." It is classified as Class 3 under this standard.
2. Chemical Ingredient Equivalence/SafetySubstantially Equivalent: "All the chemical ingredients of CLEARFIL SA CEMENT, the subject device, have been used in the predicate devices, PANAVIA F2.0 and CLEARFIL ESTHETIC CEMENT & DC BOND. It indicates that the safety of the applicant device is substantially equivalent to that of the predicate devices." (References tables in "Section 7: Substantial Equivalence Discussion")
3. Effectiveness/Performance Equivalence to Predicate (MAXCEM) based on ISO 4049: 2000Effective as well as the predicate: "As to comparison with the predicate device, MAXCEM, according to ISO 4049; 2000, it was proved that both the subject one and the predicate one complied with ISO 4049: 2000 and the subject one should be effective as well as the predicate one." This implies comparative testing against MAXCEM, although specific numerical performance results are not provided in this summary, only the conclusion of compliance and equivalence.
4. Intended Uses EquivalenceEquivalent: "It is intended to be used for the indications listed in the left hand column of the table of "Section 5: Executive Summary, Table 5" that are equivalent to the predicate devices, PANAVIA F2.0 and CLEARFIL ESTHETIC CEMENT & DC BOND." (Specific indications are listed in the "Indications for Use" section of the 510(k) – e.g., cementation of crowns, bridges, inlays, onlays, metal cores, resin cores, metal posts, glass-fiber posts.)
5. Biocompatibility EquivalenceSubstantially Equivalent: "All the chemical ingredients of CLEARFIL SA CEMENT, the subject device, have been used in the predicate devices... From those tables [on chemical ingredients], it can be said that the safety of the subject device is substantially equivalent to the predicate devices."

Study Information:

  1. Sample size used for the test set and the data provenance:

    • The document does not explicitly state the sample size used for specific tests within ISO 4049: 2000 or for the comparative effectiveness study against MAXCEM.
    • Data provenance is not specified (e.g., country of origin, retrospective/prospective). Dental material testing standards like ISO 4049 typically involve in vitro laboratory tests.
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • This information is not applicable as the studies described appear to be in vitro laboratory tests (compliance with ISO 4049) rather than studies requiring expert interpretation of clinical data or images.
  3. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

    • This information is not applicable for in vitro laboratory tests.
  4. 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:

    • No, an MRMC comparative effectiveness study was not done. This device is a dental cement, not an AI-assisted diagnostic tool.
  5. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:

    • Not applicable. This isn't an algorithm; it's a dental material.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

    • For compliance with ISO 4049, the "ground truth" would be established by the measurement protocols and physical properties defined within the ISO standard itself, measured by laboratory equipment. For example, mechanical strength, film thickness, water sorption, solubility, etc.
  7. The sample size for the training set:

    • Not applicable. This is a physical product, not an AI model requiring a training set.
  8. How the ground truth for the training set was established:

    • Not applicable. (Same as above).

Summary of the "Study":

The "study" referenced in the 510(k) summary is primarily focused on demonstrating compliance with the international standard ISO 4049: 2000 ("Dentistry - Polymer-based filling, restorative and luting materials") for the physical and chemical properties of the dental cement. Additionally, a comparative evaluation against a predicate device (MAXCEM) was performed to show that both met the ISO standard, leading to the conclusion that the subject device is "effective as well as the predicate one." The primary evidence for substantial equivalence lies in the chemical composition being identical to or derived from predicate devices, and the material's physical properties meeting an established performance standard. No clinical trials or human-reader studies are mentioned or evidently required for this type of device and submission.

Dear Mr. Nishida:

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 (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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
