No
The device description and performance studies focus on the material properties and physical performance of a root canal sealer, with no mention of AI or ML technologies.
Yes
The device is a permanent root canal filling and sealing material used following pulp-extirpation or removal of infected pulp, which constitutes a therapeutic intervention for dental health.
No
The device is a permanent root canal filling and sealing material, which is a therapeutic device rather than a diagnostic one. It is used to obturate (fill) the root canal, not to identify or assess a medical condition.
No
The device description clearly states it is a "premixed ready-to-use, injectable white hydraulic bioceramic paste" packaged in a syringe with disposable tips, indicating it is a physical material and delivery system, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "Permanent obturation of the root canal," which is a dental procedure performed in vivo (within the body) to fill and seal the root canal space.
- Device Description: The device is a "Root Canal Bioceramic Sealer," a material used to fill the root canal. This is a therapeutic device, not a diagnostic one.
- Lack of Diagnostic Function: There is no mention of the device being used to diagnose a condition, analyze a sample in vitro, or provide information about a patient's health status based on testing of biological specimens.
IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device is used directly within the patient's body for treatment.

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.
The performance of the Injectable Root Canal Bioceramic Sealer conforms to ISO 6876:2012 Dentistry - Root canal sealing materials.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench testing was performed per ISO 6876:2012 and internal procedures to ensure that the Injectable Root Canal Bioceramic Sealer met its specifications. All tests were verified to meet acceptance criteria. Test results on Appearance, Loading capacity, Flow, Setting time, Film thickness, Dimensional change following setting, Solubility and disintegration, Radio-opacity, PH, Heavy metal content and Microorganism of the subject device are very similar to predicate device. Biocompatibility testing was performed to verify the equivalent safety of the materials that are used.
According to ISO 10993-1:2018, we evaluated and conducted the compatibility test for the proposed device. The biocompatibility testing results for Cytotoxicity, Skin sensitization, Salmonella typhimurium reverse mutation assay (Ames test), Mouse lymphoma cells (TK) gene mutation test, Acute Systemic Toxicity Test, Subchronic systemic toxicity Test, Bone implant test, and Endodontic usage Test all passed.
No clinical study is included in this submission.
