Oral Pathology as part of the Head and Neck Pathology is an
interdisciplinary field of science. The oral mucosa and the saliva are
reflectors of many systemic diseases of the organism and therefore
valuable parameters of the diagnosis and prognosis of pathological
processes. In the last years many new methods have been integrated in
the diagnostic repertoire. Proliferation markers are of predicitive
value and characterize the biological behavior of a tumor. Markers are
such as oncogenes, growth factor receptors or genetic aberrations. The
importance of these new markers shall be discussed concerning the
different types of oral cancers and salivary gland tumours.
