Abstract：AIM:To evaluate the root canal obturation effects of warm gutta-percha vertical comdensation and cold gutta-percha lateral condensation techniques.METHODS:30 extracted human teeth with single root were randomly divided into two groups(n =15 ),the canals were instrumented and filled with System B &Obtura Ⅱ by warm vertical condensation and cold lateral condensation respectively.The roots were sectioned vertically and were ob-served under light microscope for the evaluation of filling density.The percentage of gutta-percha filled area (PGFA) at apical,middle and cervical parts of the root canals was measured using an image analysis soft ware.RESULTS:The PGFA(%)of the apcial area in warm vertical condensation group and cold gutta-percha lateral condensation group was 95.6 ±1.7 and 84.4 ±2.5 (P<0.05),in the middle area 90.2 ±1.4 and 93.6 ±3.1 (P<0.05),in the cervical area 98.3 ±2.3 and 97.4 ±3.4(P>0.05)respectively.CONCLUSION:Warm vertical condensation produced sig-nificantly higher PGFA in the apical part of root canal than cold lateral condensation technique.
