More Information

Not Found

No
The device description and performance studies focus on the physical and biological properties of a calcium hydroxide paste, with no mention of AI or ML.

No
The device is described as an ointment material that fills the root canal and is used as a temporary root canal filling material, indicating it is a dental material, not a therapeutic device.

No

This device is a material used for temporary root canal filling, not a device that provides diagnostic information about a patient's condition.

No

The device description clearly states it is a "calcium hydroxide paste with barium sulfate," which is a physical material, not software. The performance studies also focus on physical properties and biocompatibility of the material.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to temporarily fill the root canal for various dental procedures. This is a direct application within the body for therapeutic or restorative purposes.
  • Device Description: It's a calcium hydroxide paste used as a temporary root canal filling material. This is a material placed inside the body.
  • Lack of IVD Characteristics: IVD devices are used to examine specimens (like blood, urine, tissue) taken from the human body to provide information about a physiological state, health, disease, or congenital abnormality. This device does not involve the analysis of such specimens.

The device described is a dental material used in a clinical setting for direct application within the patient's body.

Dear Kab Lee:

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. 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 located 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.

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

9. Conclusion

"Root Canal Filling Materials (model name: DiaPaste)" was compared to "Root Canal Filling Materials (model name: Diapaste) which has similar purpose of use, principle of action, method of use and test specifications. The purpose of use, principle of action, test standard, and method of use were the same as the comparison product, but there were differences in performance, and the raw materials were similar except for some components. In addition, there were no cases of biological side effects reported so far for the licensed product, and the biological safety test results for the applied product were judged as "suitable" for all items. DiaPaste is determined to have a level of biological safety that satisfies risk-benefit analysis based on the clinical use history of similar market products when used according to the intended use and methods of use.
