2. 2 Early Dysplasia Moderate Dysplasia Severe Dysplasia Carcinoma-In-Situ (CIS) Invasive Squamous Cell Carcinoma (SCC) Appropriate Stage for Discovery & Intervention Potentially Malignant Disease Stages EARLY DETECTION IS THE KEY 67% of all oral cancer is currently discovered beyond this stage. (Stage II)

3. Fluorescence ↓ Breakdown of Collagen Matrix (prelude to invasion) Collagen cross-links ↓ Micro-Vascularization (recruitment of new blood supply) Inflammation Blood absorption ↑ Nuclear back-scattering ↑ Fluorophores excited ↓ Metabolic Activity ↑ FAD ↓ Tissue Fluorescence and Dysplastic Progression Fluorescence ↓ Florescence intensity decreases with dysplastic progression

19. NEW CLINICAL STUDIES Impressive New Findings for VELscope –Recent 620-patient study at University of Washington found that 11.1% of patients had lesions only detected by the VELscope exam In addition to oral cancers and precancers, VELscope was powerful in detecting –Viral, fungal and bacterial infections –Inflammation – including lichen planus, other lichenoid reactions –Squamous papillomas –Salivary gland tumors

20. Implementation In Your Practice VELscope Provides Extensive Training DVD Recorded Modules Live Webinar Training Taped Webinar Training Training and Case Studies on the VELscope Website www.velscope.comwww.velscope.com Regular Seminars and Courses Oral Pathologist Consultation

21. Who and how often? It is recommended that all patients 14+ should have an enhanced annual oral soft tissue exam. HPV is on the rise! –Tobacco users, heavy alcohol users and patients with a prior history of cancer should have exams every 6 months The exam should have two key components: 1.Conventional white light exam with palpation 2.VELscope examination DO THE RIGHT THING AND SCREEN ALL OF YOUR PATIENTS 14 AND OVER!

22. What Should You Charge? The dental code, D0431, is increasingly being covered by insurance companies as oral cancer continues to increase. For a mere 1.5 - 2 minute exam, the average charge for the VELscope is approximately $24. Even without reimbursement, at $15 per exam, 4 exams/day, ROI in only 8 weeks

23. You are doing a potentially life saving exam. This is a non negotiable part of the exam.

24. VELscope Endorsements June 30, 2010 – World Health Organization recognizes VELscope as “an innovative device” that addresses global health concerns –1 of 8 commercial devices to be so honored –The only dental device to be honored AGD – partnership with LED Dental / VELscope –12 oral cancer screening courses with CDE –Includes advertising for VELscope Vx University of Washington study led by Dr. Ed Truelove –Impressive new findings with use of VELscope by GPs –Clear case for expanded/routine usage in clinical practice Many NA teaching hospitals and over 100 thought leaders are “VELscope lovers”
