Abstract
OBJECTIVE: To investigate the presence of voids in bulk fill
flowable composites.
METHODS: This study investigated two well-known bulk-fill
flowable composites, Smart Dentin Replacement (SDR)
(Dentsply/Caulk, Milford, Germany) and Filtek bulk fill flowable
(FBF) (3M ESPE, Minnesota, USA). Three ampules
of each material were randomly selected. The ampules
were subjected to 3D Micro-CT (General Electric Phoenix
V|Tome|X L240) reconstruction in order to assess the
presence of any voids within the ampules.
RESULTS: Voids were present in all the ampules. The total
void percentage for each group of three ampules was
found to be SDR : 1.147 % and FBF : 0.0424 %. There was
a significant difference between the volume of voids for
SDR and FBF, p-value=0.003924.
CONCLUSION: Voids were found in the randomly selected
samples of bulk-fill flowable composites. This is undesirable
and manufacturers should be urged to ensure that no
voids are present, or at least are minimized in the ampules
of material.
