Device Story

Novidia™ Flowable Composite is a low-viscosity, radiopaque, visible light-activated dental restorative material. Composed of a resin matrix (UDMA, Bis-GMA, TEGDMA) and inorganic fillers (alumino-silicate glass, silica dioxide, pigments). A portion of silica filler is covalently bound to quaternary ammonium residues (QASi) to maintain restoration integrity. Provided in syringes or single-dose capsules in three shades. Used by dentists in clinical settings for restorative procedures. Applied to cavity preparations and cured using a dental light source (430-490 nm). QASi incorporation aims to prevent microbial degradation and preserve surface integrity, though clinical outcomes regarding this benefit are not established. Output is a hardened, tooth-colored restoration.

Clinical Evidence

No clinical or animal data provided. Bench testing only. Performance assessed via ISO 4049 standards for flexural strength, elastic modulus, compression strength, shade stability, polymerization conversion, viscosity, water solubility/sorption, depth of cure, radio-opacity, and Knoop hardness. Biocompatibility confirmed via ISO 10993/7405 testing including cytotoxicity, irritation, systemic toxicity, pyrogenicity, and genotoxicity (Bacterial Reverse Mutation, Mouse Lymphoma Assay). Atomic force microscopy used to demonstrate resistance to microbial degradation.

Technological Characteristics

Low-viscosity, light-activated methacrylate resin (UDMA, Bis-GMA, TEGDMA). Inorganic fillers: alumino-silicate glass, silica dioxide, pigments. Includes 1.2% wt/wt quaternary ammonium (QASi) modified silica filler. Curing: 430-490 nm light, ≥550 mW/cm2 intensity. Radiopaque. Complies with ISO 4049:2009. Packaging: 2g syringes or 0.2g single-dose capsules.

Indications for Use

Indicated for patients requiring Class III and V restorations, minimally invasive cavity preparations, base/liner placement, repair of esthetic indirect restorations, pit and fissure sealing, undercut blockout, and repair of resin/acrylic temporary materials.

Regulatory Classification

Identification

#### DEVICE DESCRIPTION 5.4

Novidia™ Flowable Composite is a low viscosity, visible light activated, radiopaque, flowable composite indicated for minimally invasive cavity preparations as well as various other indications.

The resin matrix of the Novidia™ Flowable Composite contains Urethane dimethacrylate (UDMA), Bisphenol-a glycidyl dimethacrylate (Bis-GMA) and triethylene glycol dimethacrylate (TEGDMA).

The inorganic filler of the Novidia™ Flowable Composite is a mix of particles of alumino-silicate-based glasses, silica dioxide and pigments. A small percentage of the silica-based filler particles are covalently bound to quaternary ammonium residues (OASi), added to maintain the integrity of the restoration.

Note: "Clinical studies demonstrating that the presence of OASi in this device improves clinical outcomes have not been conducted".

The Novidia™ Flowable Composite is provided in syringes (2 g) and in single-dose capsules (0.2 g) and is available in three shades (A1, A2 and A3).

#### 5.7 PERFORMANCE DATA

## Non-Clinical Performance Testing:

Non-clinical and biological testing was completed to assess the performance and biocompatibility of the Novidia™ Flowable Composite and to support substantial equivalence. The data provided in this 510(k) submission shows that the composite is biocompatible based on the biocompatibility assessment conducted as per ISO 10993 and ISO 7405 and performs as intended based on the bench testing per ISO 4049 and FDA guidance document "Dental Composite Resin Devices - Premarket Notification [510(k)] Submissions". The list of these tests is provided in Table 5-2.

Table 5-2: List of Tests Completed on Novidia™ Flowable Composite

An additional test that was performed is "Preservation of Surface Integrity". This study used the atomic force microscopy (AFM) method to test the hypothesis that incorporation of QASi into the Novidia Flowable Composite prevents the increase of surface roughness (a surrogate measure of material degradation) caused by biofilm. The study concluded that the Novidia Flowable Composite with 1.2% (wt/wt) QASi filler is resistant to microbial degradation evidenced by preserved surface roughness in presence of continuous microbial challenge and therefore supports the thesis that 1.2% QASi filler improves the integrity of the dental composite restorations and preserves its functionality over time. Clinical studies demonstrating that the addition of 1.2% wt/wt QASi results in enhanced clinical outcomes have not been conducted.

# Animal and Clinical Performance Testing:

Animal and clinical performance data was not included.

#### 5.8 CONCLUSION

Nobio Ltd. believes that Novidia™ Flowable Composite is substantially equivalent to the Filtek™ Supreme Ultra Flowable Restorative and other legally marketed products. It does not introduce new indications for use, has similar technological characteristics and does not introduce any new safety or effectiveness concerns.
