Thirty extracted human single-root teeth were instrumented to #45 file size while creating a continuous coronal taper. Canals were obturated with Roth 801 sealer and either JS Quick-Fill or lateral condensation of gutta-percha. Mean apical linear microleakage of India Ink was evaluated in cleared teeth using a stereomicroscope. Significantly less leakage (p < 0.1) occurred with lateral condensation than with JS Quick-Fill.
选取30颗拔除的人单根牙，预备至45号锉的尺寸，同时形成连续的冠部锥度。根管使用Roth 801封闭剂和JS Quick-Fill或牙胶尖侧方加压充填进行封闭。使用体视显微镜对透明牙齿中印墨水的平均根尖线性微渗漏进行评估。与JS Quick-Fill相比，侧方加压充填时的渗漏显著更少（p < 0.1）。
