Concentration of thromboxane B2 in gingival tissues in relation to main clinical parameters of periodontal health

: Considering the role played by some metabolites of Arachidonic Acid in the pathogenesis of periodontal disease, the Authors have investigated on the existence of a relation between the Thromboxane B2 concentration in gingival tissues and the principal clinical Indices of periodontal health: Gingival Index, Plaque Index, pocket depth, and Bleeding Time Index. The results showed that just the bleeding Index resulted to be well related to the Thromboxane B2 tissue concentration and then to the level of inflammation of deep periodontal tissues. On the ground of these data the Authors underline the importance held by the bleeding index in the showing to the Clinician the therapy necessity of a periodontal site in order to prevent a possible future attachment loss.
