  abstract = {The effect of ultrasonic debridement on cleaning isthmuses and   the effect of obturation techniques on filling of isthmuses   in mandibular first molars were evaluated.  Sixty molars with two mesial canals were instrumented by rotary instruments, divided into four groups (15 each). Group 1 & 2 were irrigated by PUI (passive ultrasonic irrigation) or by hand irrigation with %5.25 NaOCl and not obturated. Group 3 & 4 obturated by Microseal or lateral condensation after   passive ultrasonic irrigation.  The roots were sectioned at horizontally different levels, the quantity of debris was evaluated under stereomicroscope and the percentage of obturated area in isthmus was statistically analyzed (ANOVA and Newman-Keuls). The highest incidence of isthmus was found in the 3.5 mm sections of the roots.  PUI was found to be more effective than hand irrigation to clean isthmuses in mandibular molars (p<0.05). More gutta-percha content was found in Microseal obturation than lateral condensation (p<0.05). Ultrasonic instruments were found to be effective to clean isthmuses and Microseal was superior to lateral condensation technique on obturating isthmuses.},
