RESUMO
OBJECTIVE: This study aimed to evaluate cytology diagnosis accuracy using adjuvant methods in clinical routine for oral cancer. STUDY DESIGN: This prospective study was conducted on 98 patients with clinically potentially malignant or malignant oral cavity lesions. One oral lesion smear was taken from each patient using a cytobrush before biopsy and stored at PreservCyt Thinprep. Samples were cytologically analyzed, and DNA ploidy measurement was performed on the same slide. The diagnostic methods' accuracy was then calculated. RESULTS: In clinical inspection, 61 patients had suspicious lesions for malignancy, whereas 37 had potentially malignant disorders. Cytology associated with DNA image cytometry presented a sensitivity of 81.2% and specificity of 90.9%. When analyzing lesions located in high-risk sites to oral malignancies individually, cytology associated with DNA image cytometry presented a sensitivity of 88.2%, specificity of 100.0%, accuracy of 90.0%, and Kappa value of 0.77 (CI 95%: 0.48-1.00). CONCLUSIONS: Association between cytology and DNA image cytometry is an objective and non-invasive diagnostic method that demonstrated high sensitivity and specificity in diagnosing malignant epithelial squamous cell transformation in the oral cavity.

Este artigo aborda 18 casos de fibroma ossificante periférico (FOP) diagnosticados no Centro de Referência de Lesões Bucais da Universidade Estadual de Feira de Santana/Bahia, no período de 2002 a 2008. Para descrever a relação entre as variáveis sociodemográficas com o FOP, utilizou-se o Statistical Package for Social Science (SPSS), versão 10.0 for Windows (1998). Observou-se maior acometimento desta doença na quarta década de vida, sexo feminino e cor não branca. A gengiva superior anterior foi a região de maior prevalência. Faz-se importante que os cirurgiões-dentistas conheçam as características do FOP para o correto diagnóstico.
