Biochemical markers of the periodontal ligament.
For many years the diagnosis of Periodontal Disease has been based on clinical and radiographic methods. Other more recent methods have the objective of studying the inflammatory response of the host. That way, immunologic and biological methods determine the free mediators in the periodontal infection. The components of the gingivo-crevicular liquid or fluid are used to identify or to diagnose the active disease, to anticipate the risk of acquiring the disease and to determine its progress. For it to be clinically useful important changes should be registered the way a specific site turns active or that a previously disease affected site improves its conditions as a result of periodontal therapy. The response of the neutrophillic granulocytes play an important role in the detection of Periodontal Disease. The unspecific defense system in the gingivo-crevicular fluid can be determined through cytokines and/or interleukines that serve to identify sites at risk on the patient. In Periodontal Disease, the cytokines are not only defense mediators of the gingival sulcus fluid, but are also an indicator of tissue destruction. The liberation of high levels of lysosomal enzymes by neutrophils, proteolytic enzymes as the collagenases, or intercytoplasmatic enzymes as dehydrogenase lactate and aspartate amino transferase can equally help monitor the progress of the Periodontal Disease.
