Abstract

Aim: The aim of this study is to evaluate the microleakage of a new cold flowable silicone based sealer after
application to the root canals by different obturation techniques using bacterial leakage method.
Materials and Methods: In our study 100 single rooted maxillar incisor teeth were used. Teeth were caries free and
have straight canals and fully matured apexes. Teeth were divided into four experiment (20 teeth) and two control (10
teeth) groups after decoronated from CEJ. All teeth in experiment groups were root filled by using GuttaFlow due to
the manufacturers manuel and then observed for bacterial leakage for 60 days. Leakage ratios compared between
groups.
Results: In our study Group l (GuttaFlow canal tip and single cone technique) showed least leakage and Group lV
(lentulo and lateral condensation technique) showed most leakage amongst all groups. Also according to the speed of
leakage, Group l was the slowest and Group lV was the fastest amongst all groups. The rate of bacterial leakage was
analysed statistically using Fisher’s Exact Chi-Square Test. The speed of bacterial leakage was analysed statistically
using Kaplan-Meier analyse and Log-Rank Test.
Conclusions: GuttaFlow shows adequate resistance to bacterial leakage if used under the directions of the
manufacturer and applied by a canal tip and single cone technique. Considering the sealing abilities, GuttaFlow can be
a good alternative to existing root canal sealers.
