title: [The diagnosis value of malignant tumors in the Oral and Maxillofacial region using healthy person's free radical of hair]
abstract: Electron spin Resonance(ESR) was used to determine the free radical of hair from 324 cases.These cases included 185 healthy persons,33 benign tumor patients,84 malignant cases and 22 oral mucosa disease cases.The determined results were controlled with pathologic diagnosis to analyse the accordance. The result showed the positive rates of above mentioned cases were 5.9%,6.1%,84.52%and 9.1% respectively.The significant differences were observed when comparing the results of malignant cases with healthy person and benign tumor cases with healthy person and benign tumor cases(P<0.01).The ESR saturation power points of some malignant cases rose to above border-line(>10.0mW) after treatment.These results indicated using ESR to diagnosis early malignant cases and follow treatment effect possess certain clinical value.
