What is the flexural strength of SMITE Flow?

SMITE Flow achieves a mean flexural strength of 137.68 MPa (SD ±6.20), with a peak value of 147.71 MPa. This meets and exceeds the ISO 4049:2019 minimum requirement of 80 MPa for Type II flowable composites. Tested at an accredited Dental Research Center in Egypt on 10 specimens per standard protocol.

What filler percentage does SMITE Flow contain?

SMITE Flow contains 75% barium glass filler by weight, with a particle size of 2 micrometers (2μm). The remaining 25% is a methacrylate resin matrix incorporating Long-Chain Nano Technology. This high filler load significantly reduces polymerization shrinkage and improves mechanical properties compared to conventional flowable composites (typically 50-65% filler).

Is SMITE Flow radiopaque?

Yes. SMITE Flow has a radiopacity greater than 2mm aluminum equivalent, meeting the ISO 4049:2019 requirement for radiopacity (minimum 1mm Al equivalent). This ensures clear visibility on dental radiographs for proper diagnosis and monitoring of restorations.

What is the depth of cure for SMITE Flow?

SMITE Flow achieves a depth of cure of 2mm under standard LED curing light at 40 seconds exposure. This meets the ISO 4049:2019 depth of cure test requirements and ensures complete polymerization through clinically relevant layer thicknesses.

⚗️ COMPOSITION

75% Filler Load — Why It Matters

The filler-to-matrix ratio is the single most important factor determining a composite's mechanical performance. SMITE Flow's 75% filler load places it at the top of the flowable composite category.

75% Filler

Barium Glass Filler Silanated, 2μm particle size. Provides strength, radiopacity, and wear resistance. Barium glass specifically gives superior radiopacity for easy radiographic detection.

75%

Methacrylate Resin Matrix Long-Chain Nano Technology™ resin. Provides workability, adhesion, and polymerization. Lower matrix content means lower shrinkage stress on the restoration margins.

25%

Why 75% vs typical 50–65%?

Higher filler load = more glass particles = more surface area bearing mechanical stress = higher flexural strength. This is why SMITE Flow achieves up to 148 MPa while many standard flowables reach only 90–110 MPa.
