Microhybrid Composite

By the Dental Nation clinical team — a licensed dental group practising in the UAE

A microhybrid composite was tested in molar cavities, where polishing methods were compared by measuring surface roughness.

[1][2]

The short answer

Microhybrid composite was one of three composite groups used to restore standardized occlusal cavities in mandibular molars in laboratory research.

What is microhybrid composite?

How microhybrid composite was tested
Study itemDetails
Tooth typeThe study used mandibular molars with standardized occlusal cavities.[1][2]
Composite groupsNanofilled, nanohybrid and microhybrid composites were the three groups.[1][2]

[1][2]

What was measured after curing
StageMeasurement
After curingSurface roughness was evaluated with a stylus contact profilometer.[1][2]
After polishingRoughness was measured to assess the effect of each polishing system.[1][2]

[1][2]

Which surface property is studied?

The laboratory comparison measures surface roughness after curing and after polishing. It uses a stylus contact profilometer to compare the effect of polishing systems on each composite group.

[1][2]

Where was microhybrid composite placed in the study?

Microhybrid composite was placed into standardized box-shaped occlusal cavities in mandibular molars. Each cavity measured 5 mm by 3 mm by 2 mm in the laboratory study.

[1][2]

Which other composite groups were included?

Nanofilled and nanohybrid composites were tested alongside microhybrid composite in the molar-cavity study. The wider review also compares nanofilled, nanohybrid and hybrid resin-based composites in direct posterior restorations.

[1][2]

Why is polishing part of the research?

Five polishing systems were used after curing: Shofu, Optragloss, Diacomp-Plus Twist, Kenda and Sof-Lex spiral. The comparison measures how each system changes surface roughness for each composite.

[1][2]

Why does a smooth surface matter?

Surface roughness can contribute to plaque accumulation, microleakage, discoloration and secondary caries. Polishing systems aim to produce smooth composite surfaces for long-term clinical success.

[1][2]

Frequently asked questions

What did the microhybrid study measure after polishing?

It measured post-polishing surface roughness to compare the effectiveness of different polishing systems on each composite group.
