title: [Laboratory tests in periodontology].
abstract: The dentist may prescribe biological examinations in periodontics in view of confirming the diagnosis of a general disease or preparing a therapeutical treatment. Biological tests are necessary to evaluate the activity of periodontal disease. Even if research is carried out at microbiological and immunological level and on the substances related to tissue wearing, only two examinations are possible today in clinics: optical microscopy, DNA probes.
