Background:
Premixedcalcium silicate-based sealers are ready-to-use, injectable
materials with advantageous biological properties that create
environment favorable for periapical tissues repair and health.
The aim of our study was to examine the radiopacities of premixed
calcium silicate-based sealers:TotalFill BCSealer, EndoSequence BC
Sealer, Ceraseal, Bio-C Sealer and to compare them with
epoxy-basedsealer,AH Plus.
Material and methods: Three specimens (2 mm thick and 5 mm in
diameter) of each sealer were radiographed using charge-coupled
device-baseddigital sensor (Trophy Radiology, Cedex, France) along with
an aluminum stepwedge reference.For radiopacity determination, a graph
of the logarithm of aluminum thickness versus radiographic density was
plotted and a calibration curve was generated. Radiopacities were
assessed from the graph and presented as millimeters of aluminum per
millimeter of material (mmAl).ANOVA with a post hoc Tukey test was used
for statistical analysis and significance was set at 0.05.
Results: Radiopacity values of EndoSequence BC Sealer and Bio-C
Sealerwere significantly lower than radiopacities of Ceraseal and AH
Plus. Differences in values between EndoSequence BC Sealer and Bio-C
Sealer as well as between Ceraseal and AH Plus were nonsignificant.
TotalFill BC Sealer was nonsignificantly different from all other
sealers.
Conclusion: Premixed calcium silicate-based endodontic sealers
evaluated in our study had radiopacity values higher than 9 mmAl, in
ascending order,from Bio-C Sealer, EndoSequence BC Sealer, TotalFill BC
Sealer to Ceraseal.
