Comparison of apical sealability of three obturation techniques (an in vitro study)

Abstract

The aim of this study was to evaluate the sealing ability and the time required to
complete obturationof three different obturation techniques.The palatal roots of sixty
maxillary first molar teeth were selectedfor this study. The root canals prepared using
ProFile rotary instruments to an apical dimension of size 40 (.06 taper). Thespecimens
were then randomly divided into 3 experimental groups (20 sample of each) and filled
with gutta-percha and sealer byusing either cold lateral compaction, Thermafil, or the
Easy & Quick Master system.For the first parameter(Time of obturation), the results
showed that Thermafil technique required the least time to complete obturation and it
was significantly lower than other twogroups.The second measurement
(Microleakage) showed that the lateral condensation technique leaked apically and
significantly higher than other test groups, while the Thermafil group exhibited the
least value of apical microleakage.
