Intended Use

Permanent obturation of the root canal following vital pulp-extirpation.
Permanent obturation of the root canal following removal of infected or necrotic pulp and placement of intracanal dressings.
Injectable Root Canal Bioceramic Sealer is suitable for use in the single cone and lateral condensation technique.

Device Description

NRSP Injectable Root Canal Bioceramic Sealer is a convenient premixed ready-to-use, injectable white hydraulic bioceramic paste developed for permanent root canal filling and sealing applications. NRSP is an insoluble, radiopaque and aluminum-free material based on a strontium silicates composition, which requires the presence of water to set and harden. NRSP does not shrink during setting and demonstrates excellent physical properties. NRSP is packaged in a preloaded syringe and is supplied with disposable Intra Canal tips. NRSP may be delivered into the canal via the disposable tips or it can be delivered via traditional methods. NRSP Injectable Root Canal Bioceramic Sealer is available in three preloaded syringe mode that provide different in specification in5g,3g,2g,1g and 0.5g. The only difference between the types are the net weight.
Root canal filling paste is a pre mixed paste material consisting of an inorganic powder system and an organic mixed liquid. It can solidify in a humoral environment, effectively seal the root tip, and has good biocompatibility; The curing time is stable and less affected by root canal moisture and humidity; It has excellent X-ray resistance, fluidity, antibacterial properties, non staining of teeth, and no irritation.

AI/ML Overview

The provided document is a 510(k) premarket notification for a medical device called "Injectable Root Canal Bioceramic Sealer." It does not contain information about an AI/ML powered device or study results related to AI/ML performance.

Therefore, I cannot extract the requested information regarding acceptance criteria and study details for an AI-powered device. The document primarily focuses on non-clinical bench testing and biocompatibility testing for a traditional medical device (root canal sealer) to demonstrate its substantial equivalence to a predicate device.

The tables and information presented are for the non-AI root canal sealer, for example:

  • Table 1: Comparison to Predicate Device lists characteristics of the proposed device and its predicate, showing "Same" for many attributes like product code, regulation number, class, indications for use, chemical composition, and performance standard conformance.
  • Table 2: Biocompatibility testing details various biocompatibility tests performed on the device (e.g., In Vitro Cytotoxicity, Skin sensitization, Ames test, Acute Systemic Toxicity Test, Bone implant test, Endodontic usage Test), all of which resulted in "Pass" for the "Proposed device."

Since the request is specifically about "acceptance criteria and the study that proves the device meets the acceptance criteria" in the context of AI/ML, and the document describes a non-AI medical device, I cannot fulfill the request as phrased.

Dear Hao He:

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.

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.

Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
