The purpose was to evaluate the in vitro apical seal of root canals obturated with Diadent DiaPro .04 and .06 taper gutta percha points.;Sixty eight canals of extracted human teeth were instrumented with ProFile Series 29, 0.06 taper rotary files. Canals were obturated as follows: (Group 1) cold lateral condensation using an ISO size master gutta percha point; (Group 2) cold lateral condensation using a DiaPro 0.04 taper master gutta percha point; (Group 3) warm vertical hybrid condensation using DiaPro 0.06 taper master gutta percha point; (Group 4) single cone obturation using a DiaPro 0.06 taper master gutta percha point. Dye leakage was measured after the teeth were rendered transparent. There was no statistically significant difference among the groups for the presence of leakage (Chi Square, p = 0.94). There was no significant difference in mean linear apical leakage among the groups (Kruskall-Wallis, p = 0.94).
