Irrigation

Various Irrigation Solution in Endodontic

• Removal of root canal debris seems to be related to:
• Canal diameter (the canal must be enlarged at least size 40 at the apex
• Viscosity or surface tension of the solution.
• Diameter of the irrigating needle.
• Depth of penetration of the irrigating needle.
• Volume of the solution used.
• Anatomy of the canal.

• Ram (1977)

Previous studies showed that both mechanical and chemical action of the irrigant were dependent upon:

• The efficiency of the delivery system (Abou-Rass M, Oglesby SW 1981)
• The tissue surface area in contact with the irrigant solution ( Baker et al. 1975, Moored WR, Wesselink PR 1982,Gomes et al. 2001, Radcliffe et al. 2004, Vianna et al. 2004,).
• The frequency of changing the solution (Moorer WR, Wesselink PR 1982)
• The total volume of the irrigant (Cunningham et al.1982,siqueira at al.2000, Sedgley et al.2005).
