SALINAS QUIROGA, Myrna Delia et al. Evaluation of filtration at endodontical obturation at crown-apical area when different barrier methods are used. Odontología Vital [online]. 2016, n.25, pp.49-56. ISSN 1659-0775.

This study analizes and compares the intracoronal sealing of 50 extracted, single rooted, human dental organs that underwent endodontic treatment; they were divided in 5 groups of 10 each, applying the materials used as barrier method: Cavit G, Ketac Molar, Perma Seal, Single Bond and to 4 groups and leaving one control group without any barrier material. Afterwards they were submerged in artificial saliva for 1 month; after this time they were stained with methylene blue at 2% and proceeded to make the cuts for their study, evaluating crown-apical filtration in 7 sections of 1 mm each along the entire root length starting immediately after the material used as a barrier method. Results: found that the adhesive Single Bond was the most effective as material barrier to avoid crown-apical filtration
