Obturation Effect of Different Filling Techniques on Isthmuses in Mandibular Molars after Passive Ultrasonic Irrigation
Journal of Research and Practice in Dentistry
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…
