An algorithm has been derived and a computer program based on it developed, which helps to the dentist to carry out fluorescent cytological investigations and make a tentative rapid diagnosis using a PC. The algorithm is based on a simple standard assessment of the cytological preparation. Efficacy of differential diagnosis of labial and buccal cancer and precancer is 91.9 +/- 3.2%.

Infiltration fluorescein test based on examination of the strength of tissue structures subject to dystrophy in cancer is suggested to improve the results of differential diagnosis of cancer and precancer. The diagnosis is made depending on the appearance or absence of fluorescein drops on a tumor surface in response to injection of fluorochrome dose into the tumor. A fluorescent stomatoscope is used to assess the test results. Clinical trials in 85 patients have demonstrated that the test parameters and methods of evaluation are essential to obtain correct results. A high diagnostic value of the test (9.6 +/- 3.3%) recommend it as a malignancy test during fluorescent cheilostomatoscopy.

In order to improve the results of clinical diagnostic in labial and oral precancers and cancers the contact fluorescent microscopy was performed in addition to cheiloscopy and stomatoscopy in 82 patients. Fluorescent images of precancers and cancers were described and classified. In 94.0 +/- 2.6% of the cases the diagnose was correct.
