ABSTRACT
Close relationship existing between dentobacterial plaque and chronic inflammatory periodontal disease, as well as effectiveness of conservative treatments used to eliminate chronic gingivitis, is wordly known. However, several years ago, chronic destructive periodontal disease was only solved by surgical techniques, most of them bloody and of doubtful solution for some periodontal problems; for such reasons, a study was carried out in order to learn about the role played by a medicament formed with sodium bicarbonate, sodium chloride and hydrogen peroxide, deeply applied as a paste into active periodontal pockets, after an exquisite open radicular planing. Results obtained point out that the use of this procedure effective in the therapy of chronic inflammatory periodontal disease.
