Hypothesis
Different filler size, distribution, and temperature have no effect on the packing stress and viscosity of uncured resin composite.
Conclusion
Filler size and distribution significantly affect the viscosity and packing stress of resin-composites, especially at different temperatures.
Supporting Evidence
- Packing stress and viscosity were significantly affected by filler size and temperature.
- Statistical analysis showed significant differences among the materials tested.
- As temperature increased, the viscosity of resin-composites decreased.
Takeaway
The size and type of filler in dental materials can change how thick or runny they are, which is important for how they are used in dental work.
Methodology
The study tested eight resin-composite materials at two temperatures (23 °C and 37 °C) to measure packing stress and viscosity using a precision instrument based on the penetrometer principle.
Limitations
The study focused only on specific filler sizes and types, which may not represent all resin-composites.
