Maarc Endo -L (17% EDTA)

Maarc Endo -L (17% EDTA) is a chelating agent can bind to metals via four carboxylate and two amine groups. It is a polyamino carboxylic acid and a colorless, water-soluble solid, which is widely used to dissolve lime scale. It is produced as several salts, notably disodium EDTA and calcium disodium EDTA. EDTA reacts with the calcium ions in dentine and forms soluble calcium chelates.

INDICATIONS:

• Prep canal lubricants help remove calcifications and the smear layer as well as lubricate the canal for competent instrumentation
• Contain about 17% EDTA. water-based, which allows easy access to the narrow apical area and is easier to remove than gels or creams
• Used with a surfactant to loosen up calcifications inside the root canal and facilitate canal shaping for obturation

ADVANTAGES:

• Antibacterial effect
• Helps to find the root canal entrys
• Reduces file breakage during mechanical preparation
• EDTA helps in chelating the calcium salts
• Gel helps lubricate endodontic instrument and makes penetration easier
• Carbamide peroxide in EDTA promotes internal bleaching on irrigation with hypochlorite solution
