Comparison of the Area of the Canal Space Occupied by Gutta Percha Following Four Gutta-Percha and Sealer Obturation Techniques

摘要

Sixty anterior teeth were filled using four gutta percha sealer-techniques: lateral, vertical, mechanical, and chloroform-dip. The teeth were mounted in groups and sectioned. Four levels were evaluated for area of canal obturated by gutta percha versus area empty or obturated with sealer. Lateral condensation had significantly less gutta percha in the apical two levels than the other three techniques. By the third and fourth levels, the vertical technique had significantly more sealer present than the chloroform-dip and mechanical techniques. The mechanical and chloroform-dip techniques were not significantly different at any level.
