<p>Abstract : The goal of endodontic treatment is completed with the sealing of the apical foramen at the cementodentinal junction with an inert material. At present the gutta-percha technique is dominant for obturation of curved canals.</p><p> An aim of this study was to compare the new soft-type gutta-percha point FGP-3 (GC Corporation) and the current commercial gutta-percha point (GC Corporation) by using the lateral condensation technique.</p><p> As a root canal model, we used a plastic model, which had a middle degree curved root canal model. We enlarged the root canal with K-files from ＃15 to ＃45, and applied the step-back technique. After the canal preparation, we obturated the root canal with a cold lateral condensation technique using two kinds of gutta-percha master points and ＃35 accessory points.</p><p> To evaluate the sufficiency of obturated gutta-percha, the root canal model was horizontally cut at 1, 5, and 8 mm from the apex. The cross sectional image at 1, 5, and 8 mm was analyzed using Scion Image analysis software (Scion Corporation).</p><p> Soft-type gutta-percha points changed in shape and dimension more easily than the current commercial type under the lateral condensation. At 1 and 8 mm, we found a statistical difference between the soft type and the current commercial type.</p>
