Sodium phosphate dibasic is an inorganic compound with alkaline pH and hygroscopic in nature.12 Numerous dye leakage studies have been performed on MTA when used as a root-end filling material using different types of dyes such as methylene blue, fuchsin, rhodamine B, silver nitrate, India ink, and Pelikan ink.13,14 In this study rhodamine B dye was used for dye penetration.
The root samples were stained by NaOCl-acid fuchsin method (Byrd et al., 1983) and a part of the collected root samples were cut into small pieces for extraction of second stage juveniles (J2s) and males by modified Baermann's technique (Whitehead and Hemming, 1965).

(2005) studied the efficiency of azo dyes for staining phytonematodes and found that dyes containing bordeaux, red bordeaux, and the mixture of bordeaux and 1% indigotine blue, consistently stained in red color the egg masses, eggs, juveniles and females of Meloidogyne incognita, inside the root, compared to the dyes phloxine B and acid fuchsin. However, studies regarding the use of artificial dyes for staining fungal structures are scarce.
