ProRoot MTA Root Repair Material Mixing Instructions

Note: ProRoot MTA root repair material does not set as quickly as other cements.  Careful mixing will make the material easier to handle

• Open a pouch of ProRoot MTA root repair material and dispense the powder onto a mixing pad

• Pull off the end of a ProRoot liquid micro-dose ampoule and squeeze out contents onto the mixing pad next to the root repair material

• Gradually incorporate the liquid into the cement using the ProRoot MTA mixing stick (plastic)

• Mix the material with the liquid for about one minute to ensure all the powder particles are hydrated

• If needed (one extra ampoule is provided, sterile water can also be used), one or two drops of liquid can be added to make the material into a thick, creamy consistency

Note:

1. Adding too much, or too little liquid will reduce the ultimate strength of the material
2. The ProRoot MTA root repair material will set over a period of four hours, but the working time is about five minutes.  If more working time is needed, cover the mixed material with a moist gauze pad to prevent evaporation
