The aim of this study was to evaluate the integrity of the coronal seal of Temp-Bond and compare it to
Cavit and IRM after post space preparation using S. faecalis as a microbial tracer. In addition, the affect
of two methods of gutta percha removal on the apical seal of root canal fillings was also evaluated. Forty
extracted human single rooted teeth were prepared chemomechanically and obturated with gutta percha and
AH26 sealer cement using the lateral cold condensation technique to a standardized working length of 15
