Average filler content seen in macrofilled composites is:
**Core Concept**
The question is testing knowledge of dental materials, specifically the composition of macrofilled composites. Macrofilled composites are a type of **dental restorative material** used for filling teeth. The filler content is an essential aspect of these materials, as it affects their mechanical properties.
**Why the Correct Answer is Right**
Macrofilled composites typically contain a high percentage of **inorganic filler particles**, such as glass or quartz, which are added to improve their strength and durability. The average filler content in these composites is around 70-80% by weight, which helps to reduce shrinkage and improve the material's resistance to wear.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it represents a lower filler content than what is typically found in macrofilled composites.
**Option B:** This option is also incorrect, as it is lower than the average filler content.
**Option D:** This option is incorrect because it represents a higher filler content than what is typically achievable in macrofilled composites.
**Clinical Pearl / High-Yield Fact**
Remember that the high filler content in macrofilled composites makes them more resistant to wear, but also more difficult to polish. This can affect the material's appearance and patient satisfaction.
**Correct Answer:** C. 70-80%
