Irrigation

The root canal is flushed with an irrigant. Some common ones are listed below:

  • Sodium hypochlorite (NaClO) in concentrations ranging between 0.5% and 5.25%
  • 6% sodium hypochlorite with surface modifiers for better flow into nooks and crannies
  • 2% chlorhexidine gluconate
  • 0.2% chlorhexidine gluconate plus 0.2% cetrimonium chloride
  • 17% ethylenediaminetetraacetic acid (EDTA)
  • Framycetin sulfate
  • Mixture of citric acid, doxycycline, and polysorbate 80 (detergent) (MTAD)
  • Saline
  • Near anhydrous ethanol

The primary aim of chemical irrigation is to kill microbes and dissolve pulpal tissue.[18] Certain irrigants, such as sodium hypochlorite and chlorhexidine, have proved to be effective antimicrobials in vitro[18] and are widely used during root canal therapy worldwide. According to a systematic review, however, there is a lack of good quality evidence to support the use of one irrigant over another in terms of both short and long term prognosis of therapy.

Root canal irrigation systems are divided into two categories: manual agitation techniques and machine-assisted agitation techniques. Manual irrigation includes positive-pressure irrigation, which is commonly performed with a syringe and a side vented needle. Machine-assisted irrigation techniques include sonics and ultrasonics, as well as newer systems which deliver apical negative-pressure irrigation.
