AvuePREP – EDTA gel ( Dental Avenue)

• As it is water soluble, allows it to be washed away easily by irrigating the canal.

• EDTA when used with sodium hypochlorite is an effective chelating agent.

• The lubricant in the gel helps in easier preparation of the canal.

• Phase separation is not usually seen.

• Long shelf life of 2 years from date of manufacturing.

• As compared to a paste form of EDTA, doesn’t easily coat the file.

EDTA

• 17% EDTA is an effective chelating agent, that removes the inorganic ( dentine etc) components inside the canal. It can be used after the mechanical preparation for removal of the smear layer.

• AvuePREP has 15% EDTA and is used DURING mechanical preparation. The presence of glycol in the composition enable lubrication of the canal and also prevents fracture or separation of file. It should always be preceded and followed with an irrigation of 2% or 5.25% Sodium Hypochlorite, which dissolves organic matter and has an anti-bacterial effect.

CARBAMIDE PEROXIDE

• Peroxides in concentration between 1-30% has been used widely in endodontics for disinfection and sterilization. This is usually done by the release of hydroxyl free radicals by the method of effervescence or bubbling.

• AvuePREP uses 10% carbamide peroxide. It improves the cleansing activity when used along with Sodium hypochlorite. Also effective as an anti-bacterial agent when used along with 2% Chlorhexidine, specially against secondary infections of E. Faecalis.

• Carbamide peroxide in presence of water breaks down into free radicals, which penetrates the enamel and dentine pores and causes bleaching. This can remove stains from inside the tooth (internal bleach). Though the concentration available in AvuePREP may not be effective as an internal bleach.
