This study compared the density of gutta percha when using cold lateral condensation (CLC) and continuous wave of condensation (CWC) under varying temperature and plugger depths. Seventy acrylic blocks were instrumented. The blocks were weighed and assigned to seven groups. Group 1 was obturated with CLC. The remaining six groups were obturated with CWC. Groups 2-4 were obturated by advancing the plugger to 3 mm short of the working length at 100°C, 200°C, and 300°C, respectively, and then backfilled. In groups 5-7 the plugger was advanced to 5 mm short of working length. The blocks were weighed again after obturation. Data were analyzed using a one-way ANOVA and Tukey's tests. Results indicated a significantly greater density of gutta percha when using CWC compared to CLC and when the plugger was advanced to 3 mm short of working length (p.05).
