title: Solution for the isolation of the working field in a difficult case of root canal therapy.
abstract: A technique for the isolation of a posterior tooth with large distogingival caries and which needed endodontic therapy is described. To ensure a perfect seal, avoiding contamination or infiltration of the chemicals used for irrigation during the root canal therapy, a direct resin temporary restoration was done before placing the rubber dam as required for endodontic treatment.
