Title In a Healthy Adult Requiring a Composite Restoration, SonicFill is More Effective at Reducing Polymerization Shrinkage Compared to Bulk Fill Flowable Composites
Clinical Question In a healthy adult requiring a composite restoration, does SonicFill reduce polymerization shrinkage compared to bulk fill flowable composites?
Clinical Bottom Line In a healthy adult requiring a composite restoration, SonicFill was more effective at reducing polymerization shrinkage compared to bulk fill flowable composites. This is supported by a laboratory test where SonicFill, a nanohybrid flowable composite, had the lowest shrinkage value compared to the bulk fill flowable composites.

The Evidence
Validity: This was a lab study that tested polymerization shrinkage of four different composites. Each composite was treated the same and followup was adequate. Perspective: This study is limited in is validity because it is a laboratory experiment. Clinical trials are necessary to confirm the reduced polymerization shrinkage of SonicFill compared to other bulk fill flowable composites.
Applicability This study is weak because it has not been tested in a clinical setting. More studies are needed to determine if these results will translate from the laboratory to the clinic.
