- Introduction: Early diagnosis of oral cancer ameliorates the constancy of outcomes. Efficacious untimely screening of PMDs through diagnostic addition may ease preliminary diagnosis. However certain hindrance and fetch of existing diagnostic add-on limit their extensive use. Droroscope is an economical fluorescence visualization device using blue light (400- 460nm) that expose abnormal oral tissue that cannot be glimpse by white light. Droroscope is a palmtop intraoral device with 3 lights (red, blue, green-amber).Aim: To evaluate the efficacy of Droroscope in the early detection of PMDs & malignant disorders. Objective: To observe the borders of the lesion under various monochromatic lights & to identify the specificity & sensitivity of the device in identifying lesions. Material & methods: 20 patients over 18 years of age with a clinical diagnosis of PMDs & Malignant disorders. Patient with a clinical diagnosis of oral cancer, patients suffering from systemic diseases were excluded in this study. Droroscope examination: The lesion will then be visualized with blue & green lights of the device & findings will be noted along with photographs. Lack of fluorescence on blue light will be regarded as being positive for dysplasia. Visibility of blood vessels near the surface under green light will be taken as positive change for dysplasia. Correlation between the findings of the device and histopathological findings will be done. Results: The sensitivity and specificity of this device as per the sample were 100% and 98.3%. So, DROROSCOPE was statistically effective in detecting lesions malignancy
