Comparative Analysis on Apical Microleakage in Root Canals Obturated with Gutta flow, Thermafil and Regular Guttapercha with Lateral Condensation – A Stereomicroscopic Study
Harsh Priyank, Mahalakshmi V., Ankita Verma

Aims: The aim of this study was to evaluate and compare the apical microleakage of GuttaFlow in comparison with the Cold Lateral Condensation, and Thermafil obturation technique.  Settings and Design:  In-Vitro Material Science Study. Methods and Material: Forty five extracted human maxillary incisors with intact root were selected and crown portion removed. In all the samples access was gained and working length was determined. Biomechanical preparation was done using step back technique upto size 50 K file with copious irrigation with 5.25% sodium hypochlorite and 17% EDTA. The teeth were divided into three groups of fifteen teeth each for obturation. Group I- GuttaFlow with Master cone; Group II- Thermafil group; Group III- Cold Lateral Condensation group. Following obturation, the samples were incubated followed the application of two layers of nail polish up until the apical 2mm for all the samples. All the samples were placed in India ink dye with two thirds of the roots apically submerged in the dye for seven days. The samples were then washed in running water and sectioned vertically along the long axis, short of reaching the obturation material, creating a stress canal. A chisel was then used to split the tooth. The dye penetration was then measured using stereomicroscope.  Statistical analysis used: In order to compare the means of the 3 groups, ANOVA was used. Results: Mean Apical microleakage for Thermafil group was the maximum followed by Guttaflow and Cold Lateral condensation with AH Plus sealer. However the difference was not statistically significant. Conclusions: The result in the present study showed that GuttaFlow provides a similar consistent seal as compared to either cold lateral compaction or Thermafil technique.
Key-words: Microleakage, Guttaflow, Thermafil, Stereomicroscope.
