RESUMO

The assessment of bone destruction by oral and oropharynx malignant neoplasms is a critical factor in the therapeutic planning and to determine the patient prognostic. The aim of this study was to determine the clinical aspects (localization, clinical manifestation and stage) that can be associated with the potential of bone infiltration, and also determine the physical exam sensibility and specificity. The study population consisted of twenty five patients (17 men and 8 women, mean age 57.88 years-old), with malignant neoplasms of the mouth and oropharynx, of the Stomatology Clinic of the College of Dentistry at the Sao Paulo University - campus Sao Paulo, in the period of august 2003 to august 2004, who were submitted to a clinical and computed tomography (CT) examinations. CT was considered the gold standard to evaluate the presence of bone involvement. The presence of bone destruction by the tumor was observed in 68% of the cases (17 patients). The physical examination of the patients revealed 82% of sensibility, 87.50% of specificity, and 84% of accuracy in the assessment of bone invasion by these diseases. The lesions that were clinical considered to be infiltrative ulcer and nodular lesions, non-ulcerated, presented the highest potential to cause bone destruction, 68.75% and 100% respectively. The tumor localization in specific sites also influenced the presence of bone invasion, meanly with the lesions localized in the gingival, retromolar trigone, hard palate and oropharynx. The stage of the lesions revealed a relation between the size and the presence of distant metastasis, with the presence of invasion by the neoplasm. In conclusion, it was determined that the identification of some clinical parameters such localization, clinical presentation, lesion size and the presence of distant metastasis, associated with a perceptive regional physical exam must be use as a value tool is the assessment of bone destruction by oral and oropharynx malignant neoplasms.
