title: Influence of plugger penetration on the sealing ability of vertical condensation.
abstract: This study sought to evaluate the influence of plugger penetration on the sealing ability of vertical compaction. Ninety anterior teeth were used. After cleaning and shaping to a size #30 file, these teeth were divided into three equal groups (A, B, and C) according to the level of plugger penetration set at 5, 7, and 9 mm short of the working length, respectively. Then vertical compaction was performed. Apical microleakage was determined using pressurized fluid filtration at 90 min, 1 day, and 1, 4, 12, 18, and 24 wk after root canal obturation. Leakage tended to increase over time for the three groups. The deeper plugger penetration groups (A and B) showed significantly less apical leakage than group C.
