  • Treatment of periodontitis
    Patent number: 5240696
    Abstract: The present invention relates to the prevention of periodontitis by the use of a medicament which contains Triclosan. It has been found that Triclosan has a considerable anti-cyclo-oxygenase activity, thus inhibiting the formation of prostaglandins which are mediators of the loss of alveolar bone in the periodontium. Reducing the formation of said prostaglandins therefore reduces said loss of alveolar bone, which is one of the symptoms connected with periodontitis.The medicament is preferably in the form of a toothpaste.
