Study Groups

Waterlase Express™, BIOLASE®
Root canals will be instrumented up to size 30/0.04 taper using Er,Cr:YSGG laser (Waterlase Express™, BIOLASE®), followed by standard of care (NaOCl).
Waterlase Express™, BIOLASE®
Er,Cr:YSGG laser 2780nm (Waterlase Express™, BIOLASE®) with 300μm tip (EdgePro #3) will be placed into the mid-root of the canal. The tip will be activated and slowly withdrawn to the orifice (1-2mm/sec) following the manufacturer settings (energy 15 Millijoule (mJ), repetition rate 50 Hertz (Hz), 0% air, 0% water).
Sodium Hypochlorite
Root canals will be instrumented up to size 30/0.04 taper using standard of care (NaOCl).
Sodium Hypochlorite
Root canals will be instrumented up to size 30/0.04 taper using 1.5cc of 3% NaOCl in between files.
