Excluding the control group of 30 patients 15 males and 15 females (mean age=37.5yrs) among the remaining 62 patients 22 of those who showed loss of fluorescence on tissue fluorescence imaging only 19 patients showed histopathological presence of neoplastic changes (mild/moderate/ severe dysplasia CIS and well differentiated OSCC) concluding the sensitivity of autofluorescence (VELscope) for the detection of dysplastic lesions to be 86% and its specificity in detecting neoplastic lesions and diagnosing oral potentially malignant disorders and benign lesions to be 74%.
