- To clean l interior of this tooth well, by a mechanical action: scraping of the interior surface of the pulpar channels (with l´aide of manual or mechanical endodontical files), associated with a chemical action: irrigation with sodium l´hypochlorite (bleach diluted to 3%), which is disinfecting it most effective.
- To format the canal light jusqu´au foramen apical, with l´aide of manual files or mechanized files so that the solution of irrigation penetrates everywhere.
