With the objective of statistically proving the importance of exfoliative citology in the early diagnosis of oral oncological lesions, a crosswise, analytical and observational study was carried out at "Manuel Ascunce" Provincial Teaching Hospital in Camaguey from January to December, 2000. PDCB test was performed on 248 referred patients of whom 41 were selected because they presented with lesions that seemed to be malignant or suspected of malignancy. All these lesions were applied cytological tests and biopsies. Given the characteristics of the study, they were as samples or controls depending on the applied procedures. The effectiveness of the methods is confirmed by Galen and Gambino's statistical system. Cytological results were positive in 30 patients, negative in 6, 0 suspected and 5 were useless. Biopsies showed 29 epidermoid carcinomas, 10 leukoplasias and 2 descriptive. When compared, cytology showed 100% sensitivity, 28% specificity, predictive and negative value of 81% and 100% and the global efficiency of the test was 96%. This paper proved the importance of exfoliative cytology as non-invasive diagnostic method.
