Comparison of the Sealing Ability of GuttaFlow Bioseal with Different Obturation Systems (An in vitro study)

Abstract
The major goal of a root canal filling is the three-dimensional obturation with the complete seal
of the whole canal system. The aim of this study is to quantitatively evaluate and compare the
sealing ability of GuttaFlow bioseal with different obturation systems (GuttaFlow 2, AH plus,
Bioceramic sealer) of single cone techniques.
64 freshly extracted maxillary first molars with a straight palatal root canal were selected. After
sectioning of the palatal roots, their canals were instrumented using EdgeEndo X7 rotary system in
sequence (20/04 – 40/04) then divided into 4 experimental groups according to the obturation
system, Group I: AH plus sealer, Group II: GuttaFlow 2, Group III: Bioceramic sealer, Group IV:
GuttaFlow bioseal sealer, and 2 control groups. Apical leakage evaluation was done by dye
extraction methods. Data were analyzed using One-way ANOVA, and Tukey HSD tests.
The lowest leakage was in GuttaFlow bioseal, while the highest leakage was for GuttaFlow 2.
The statistical analysis revealed that GuttaFlow bioseal had significantly lower leakage than
GuttaFlow 2 and Bioceramic sealer ( P< 0.05), while it had no significant difference in the mean
leakage when compared with AH Plus.
The type of the sealer act as a major determinant of the sealing ability when used with a single
cone technique. Bioactive glass based sealer showed the best sealing ability.
