[Electrochemical analysis in differential diagnosis of benign and malignant oral maxillofacial tumors].
A bioelectrochemical-sensor device was designed according to the principles of galvanic cell reaction. Modified bioelectrochemically, the device was used to measure the current of samples from benign and malignant tumor tissues. Statistical analysis and clinical test showed that the current values (426 microA) of the malignant tissue were higher than those (216 microA) of the benign tissue. The sensitivity and specificity were 95% and 90% respectively. This method provided important information about benignancy or malignancy of the tumor and its involvement and metastasis.
