Objective: To observe the influence of the trial point on the quality of root canal obturation. Method: 1500 cases of root canal therapy with lateral compaction during 1998.10~1999.4 were obtained randomly from Digora system. The quality of obturation was analyzed based on with and without testing the trial point. Results: There were 748 teeth with the trial point and 752 cases without. The rates of flush filled teeth were 62%, 64% and 51% with the trial point against 44%, 35% and 31% without the test in anterior, premolars and molars, respectively. The rates of underfilled teeth were reduced from 22%, 32% and 45% with the trial point to 7%, 13% and 19% without the test in anterior, premolars and molars, respectively. Conclusions: The trial point test may improve the quality of obturation with lateral compaction. [
