Capacity to remove smear layer of dentin root canal after use the vinegar of alcohol and vinegar of apple as irrigants solutions during endodontic therapy

The authors analyzed by scanning electron microscopy (SEM) the capacity to remove smear layer of dentin root canal wall after endodontic treatment. The study used premolars extracted human teeth. ProTaper System (Dentsply Maillefer) was used to endodontic instrumentation helpful by five irrigants solutions: sodium hypochlorite 1% + EDTA; sodium hypochlorite 1% + vinegar of apple; vinegar of apple; sodium hypochlorite 1% + vinegar of alcohol and vinegar of alcohol. Root longitudinal-sections were obtained and analyzed by SEM. We analyzed three regions of root canal wall: cervical third, the region located 3 mm after the root canal open; apical third, the region located 3 mm short of the apical foramen and middle third. Every samples tested, associated or single, were effectives in removal of smear layer.
