Endodontic irrigants from a comprehensive perspective

Table 1 Sodium hypochlorite types and concentrations

Solution	Concentration	Parts per million
Dakin's solution	0.5% NaOCl solution	Equivalent to 5000 ppm, and is neutralized with boric acid to bring the pH close to neutral
Dausfrene solution	0.5% NaOCl solution	Equivalent to 5000 ppm, that has been neutralized using sodium bicarbonate
Milton's solution	1% NaOCl solution	Equivalent to 10000 ppm, that is stabilized with 16% sodium chloride
Labarraque Liqueur	2.5% NaOCl solution	Equivalent to 25000 ppm
Chlorinated soda	4%-6% NaOCl solution	Equivalent to 40000-60000 ppm
Sanitary water	2%-2.5% NaOCl solution	Equivalent to 20000-25000 ppm
