VELSCOPE ASSESMBLY FOR ORAL CANCER SCREENING,PRESENTATION FOR B.D.S LEVEL PROJECTS AND RESEARCH WORK,PRESENTED AT I.D.A CONFERENCE 2017,SMALL AND SIMPLE,EASY TO UNDERSTAND FOR U.G. LEVEL

1. VELSCOPE : ASSESSMENT SYSTEM
FOR ORAL CANCER SCREENING

2. INTRODUCTION
• Advancements in dental technology offers
improved solutions to traditional dental problems
and helps detecting oral problems at an early stage.
• The driving force behind such technological
advances is a desire to provide patients with
leading edge dental treatment that can be
performed in a more efficient, effective and most
importantly comfortable manner.

3. THE VELSCOPE ASSEMBLY SYSTEM…

4. NO LONGER TO SEE OR NOT TO
SEE…
• It is a brand new oral cancer screening system
which helps in early detection of oral cancer.
• Developed by BRITISH COLUMBIA CANCER
AGENCY about 10 years ago.
• Approved by FDA and recognised by WORLD
HEALTH ORGANISATION.
• The VELSCOPE Vx enhanced oral assessment
system centers on a handheld scope and a 12 MP
high resolution digital camera that is being used by
dentists to help visualise oral tissue abnormalities.

5. • Process of ADJUNCTIVE MUCOSAL SCREENING.
• It is a pre-diagnostic test to aid in detection of mucosal
abnormalities including pre-malignant and malignant
lesions.
• It is supplemental to traditional intra and extra oral
examinations.
• Sensitivity 98%.
• Specificity 100%.

6. IT IS TIME TO TAKE A CLOSER LOOK…
• Simple and objective assessment with device that is
portable, easy to store and handle.
• Painless and comfortable for patient as no chemical
agents are used.
• No unpleasant odour, taste or sensation.
• Low cost.
• Procedure time < 3 minutes.
• Can be used as a part of patient’s
preventive examination during
routine check up.

8. MECHANISM OF ANOMALY
DETECTION BY VELSCOPE…
ABNORMAL TISSUE CHANGE
BLUE LIGHT OF 400-460 nm PENETRATES FROM EPITHELIUM TO
BASEMENT MEMBRANE TO STROMA
AUTOFLUORESCENCE OF TISSUE
FLUORESCENCE PATTERN ALTERED DUE TO DISEASE

9. NORMAL TISSUE FLUORESCENCE PATTERNS

10. DETECTS GROWTH BELOW THE
SURFACE THAT IS 1 mm WIDE &
ONLY 3 CELL THICK

12. WHAT IT CAN DETECT : APART FROM
PRE-MALIGNANT AND MALIGNANT
LESIONS
*SQUAMOUS PAPILLOMAS
*SALIVARY GLAND TUMORS
*INFLAMMATION SUCH AS LICHENOID
REACTIONS
*FUNGAL,BACTERIAL,VIRAL
INFECTIONS

13. GET IT EARLY,GET IT ALL…
• Improves clinical decision (good differential diagnosis and
treatment planning).
• Helps in detection of borders in both surgical biopsy and
excision.
• Non invasive nature of examination.
• Cost effective.
• Early discovery of oral cancer leads to
significant rise in survival rate for patients
and extensive disfigurement can also be
avoided.

14. RELATIVE DEMERITS…
• Low patient education rate about newer technology.
• Fear of pain related to dental treatments.
• Financial constraints.
• Indifference towards oral health.
• Lack of motivation for preserving
better quality of life.

15. PROGRESSION TO GOLD STANDARD FOR
SCREENING…
• More than 25 million VELSCOPE Vx examinations have been performed
by over 12,000 dental practitioners in 23 countries.
• From results of various studies conducted worldwide and also in
India(Tata Memorial Hospital, Mumbai),it was concluded that the
performance of the VELSCOPE Vx has the potential to improve oral
screening efforts especially in low resource settings.
• It is backed by more clinical studies than any other adjunctive device for
tissue fluorescence visualisation.
