Successful root canal therapy depends on correct diagnosis and planning, effective irrigation,
excellence in cleaning and shaping, accurate three dimensional obturation of the root canal system
along with a suitable treatment management. The aim of the study was to evaluate the obturation of
root canals at two positions using different percentages of gutta-percha cones. Twenty recently
extracted mandibular molars were selected for the study. Access opening was done, working length
determined, cleaning and shaping of the canal was done using ProTaper rotary instruments. The teeth
were then obturated with gutta-percha cones and AH plus sealer. Horizontal sectioning was done on
the teeth at the middle and apical third of the obturated root. Colour photographs were taken using a
camera attached to a stereomicroscope and then digitized using a scanner. The cross sectional areas of
the canal contents were analyzed using Auto CAD. The percentages of gutta-percha to the root canal
area were derived and the data was analyzed. Results showed that 2 % lateral condensation for
obturation is effective when compared to 6 % Greater Taper gutta -percha in Pro Taper instrumented

Key words: Obturation ,guttapercha, condensation, sectioning , homogenous
