Intended Use
UltraSeal XT plus bioprotection by Nobio sealant - UltraSeal XT plus sealant for prophylactic sealing of pits and fissures and can be used where the use of a flowable composite is indicated. The bioprotection by Nobio reduces demineralization, which is part of the caries formation process. UltraSeal XT hydro bioprotection by Nobio sealant - Use UltraSeal XT hydro sealant for prophylactic sealing of pits and fissures. The addition of the bioprotection by Nobio reduces demineralization, which is part of the caries formation process.
Device Description
UltraSeal XT plus bioprotection by Nobio sealant and flowable composite – UltraSeal XT plus sealant is a 58% filled, light-cured, radiopaque, methacrylate-based, thixotropic resin sealant. It is used with PrimaDry drying and priming agent to aid in avoiding moisture contamination which can cause microleakage and poor retention. It is a Type 1 Class 2 Group 1 polymer-based dental restorative flowable resin which is suitable for occlusal surfaces. It can be used where the use of a flowable is indicated. It is compatible with adhesives and bonding agents. UltraSeal XT plus sealant has a radiopacity value of 1.44 mm of aluminum. Aluminum has a radiopacity equivalent to that of dentin. Thus, 1 mm of material (having a radiopacity equivalent to 1 mm of aluminum) has a radiopacity equivalent to that of dentin-and 2 mm of aluminum is equivalent to enamel. The addition of the bioprotection by Nobio reduces demineralization, which is part of the caries formation process. UltraSeal XT hydro bioprotection by Nobio sealant – UltraSeal XT hydro sealant is a Class 2, 53% filled, light-cured, radiopaque, methacrylate-based, thixotropic resin sealant. It is partly hydrophobic and hydrophilic before it is cured, hydrophobic once cured, and has a selfadhesive quality. UltraSeal XT hydro sealant chemistry provides the option of a visual verification for marginal retention-with the use of a black light upon placement and at recall visits. The UV light is not included in the UltraSeal XT hydro sealant kit. The addition of the bioprotection by Nobio reduces demineralization, which is part of the caries formation process. Some of the silica-based filler particles (max 1.2% wt/wt of the total formulation) contained in all the UltraSeal XT plus Bioprotection by Nobio and UltraSeal XT hydro Bioprotection by Nobio are decorated with quaternary ammonium functional groups that are covalently bound to the filler particles' silica core via a silane linker (herein referred to as "QASi"). Following light induced polymerization, QASi particles (produced by Nobio) remain permanently entrapped within the sealant and destroy microorganisms by contact. As the cell membrane of microorganisms is negatively charged and the QASi particles have strong positive charges, microorganisms are electrostatically attracted to the positively charged cured material's surface resulting in disruption of their cell membrane and immediate microbial lysis. Both subject devices have a depth of cure ≥ 1.5mm, are curable at wavelengths of 385-515nm and will remain uncured after light exposure while in their primary container. UltraSeal XT plus Bioprotection by Nobio is also indicated for use as a flowable composite. It has a flexural strength of ≥ 80 MPa, Water Sortpion ≤ 40 µ g/mm3, Water Solubility ≤ 7.5 µ g/mm3, Radio-Opacity, ≥ 1mm of Al, Surface Hardness ≥ 20 HK and Ambient light sensistivity resulting in the product being physically homogeneous after 60 seconds.

No
The device description focuses on the material properties and chemical composition of the sealant, with no mention of AI or ML technologies. The performance studies are based on standard biocompatibility and bench testing, not algorithmic performance.

No.
The device is indicated for prophylactic sealing of pits and fissures and does not claim to treat or cure a disease or condition.

No

This device is a sealant used for prophylactic sealing of pits and fissures, which is a treatment or preventive measure, not a diagnostic one.

No

The device description clearly indicates that the device is a physical dental sealant material (methacrylate-based resin) with added filler particles. It is 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 the prophylactic sealing of pits and fissures in teeth and as a flowable composite. This is a direct treatment/preventative measure applied to the patient's body.
  • Device Description: The device is a resin sealant/flowable composite that is light-cured and applied to the tooth surface. It contains particles that physically interact with microorganisms on contact.
  • Lack of In Vitro Testing: The description of the performance studies focuses on biocompatibility and bench testing of the material properties (depth of cure, strength, etc.). There is no mention of testing patient samples (blood, urine, tissue, etc.) to diagnose or monitor a condition.
  • No Mention of Analyzing Samples: The device description and intended use do not involve analyzing samples taken from the human body.

IVD devices are used to examine specimens derived from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, prevention, or treatment of a disease or condition. This device is applied directly to the patient's teeth for a preventative and restorative purpose.

the use of a flowable is indicated. It is compatible with adhesives and bonding agents. UltraSeal XT plus sealant has a radiopacity value of 1.44 mm of aluminum. Aluminum has a radiopacity equivalent to that of dentin. Thus, 1 mm of material (having a radiopacity equivalent to 1 mm of aluminum) has a radiopacity equivalent to that of dentin-and 2 mm of aluminum is equivalent to enamel.

UltraSeal XT hydro bioprotection by Nobio sealant – UltraSeal XT hydro sealant is a Class 2, 53% filled, light-cured, radiopaque, methacrylate-based, thixotropic resin sealant. It is partly hydrophobic and hydrophilic before it is cured, hydrophobic once cured, and has a selfadhesive quality. UltraSeal XT hydro sealant chemistry provides the option of a visual verification for marginal retention-with the use of a black light upon placement and at recall visits. The UV light is not included in the UltraSeal XT hydro sealant kit. The addition of the bioprotection by Nobio reduces demineralization, which is part of the caries formation process.

Some of the silica-based filler particles (max 1.2% wt/wt of the total formulation) contained in all the UltraSeal XT plus Bioprotection by Nobio and UltraSeal XT hydro Bioprotection by Nobio are decorated with quaternary ammonium functional groups that are covalently bound to the filler particles' silica core via a silane linker (herein referred to as "QASi"). Following light induced polymerization, QASi particles (produced by Nobio) remain permanently entrapped within the

sealant and destroy microorganisms by contact. As the cell membrane of microorganisms is negatively charged and the QASi particles have strong positive charges, microorganisms are electrostatically attracted to the positively charged cured material's surface resulting in disruption of their cell membrane and immediate microbial lysis.

Both subject devices have a depth of cure ≥ 1.5mm, are curable at wavelengths of 385-515nm and will remain uncured after light exposure while in their primary container. UltraSeal XT plus Bioprotection by Nobio is also indicated for use as a flowable composite. It has a flexural

Conclusion:

The predicate and subject devices have identical indications for use with a slight variation highlighting the inclusion of the Nobio QASi particles that reduces demineralization. Reference device, Infinix Flowable composite (K201010), intended for use as a flowable composite and/or pit and fissure sealant, incorporates the same Nobio QASi particles that reduces demineralization. Like the predicate devices, the subject devices utilized ISO 6874 and ISO 4049 to evaluate performance aspects of the devices. Safety is further proven by testing conducted to ISO 10993-1 and ISO 7405 supporting the biological safety of the devices. Lastly, device efficacy is met with clinical acceptance as being an effective pit and fissure sealant and as a flowable restorative (UltraSeal XT plus Bioprotection by Nobio only) through simulated use testing with representative users. As such, the differences in indications for use between the predicate and subject devices does not impact safety or effectiveness of the devices.

Based on this, the similar intended use and testing information presented above for the predicate products, UltraSeal XT plus and UltraSeal XT hydro, and the subject products, UltraSeal XT plus Bioprotection by Nobio and UltraSeal XT hydro Bioprotection by Nobio, are substantially equivalent.
