| Popis: | An in vitro dye leakage study was performed to determine the incidence of patent furcal accessory canals following exposure of the pulp chamber to 5.25% sodium hypochlorite. One hundred extracted molars were labeled, endodontically opened, and irrigated for 1 h at 5-min intervals. The external furcations were exposed to 0.5% basic fuchsin for 24 h. Patency was determined by dye presence on the chamber floor. Statistical analysis revealed that first and second molars, regardless of arch position or location, demonstrated a patent accessory canal at a rate of 57% +/- 19.6% in the furcal area. It was concluded that accessory canal exposure to 5.25% sodium hypochlorite in the furcal area of molars produced patency which was demonstrable via passive methods--no vacuum or injection pressures were utilized. |
