  1. ADVANCED NON-INVASIVE TECHNIQUES IN EARLY DETECTION OF ORAL CANCER • PRESENTED BY: Abhishek Ghosh 3rd prof. B.D.S. Dr.R.Ahmed Dental college &Hospital • GUIDED BY: Dr. Jay Gopal Ray H.O.D. Dept. Of Oral & Maxillofacial Pathology

  2. ORAL CANCER : SOME DEADLY STATISTICS

  3. IMPORTANCE OF EARLY DETECTION 70% cases are diagnosed in late stages It leads to 5 year survival rate of 57% patients Oral cancer is 90% curable when detected early

  4. Why non-invasive techniques?

  5. EXFOLIATIVE CYTOLOGY • It is the histo-pathological examination of cells obtained by their physical removal,followed by placement on glass-slide and then appropriately stained.

  6. Preparation of ‘Pap-smear’

  7. VIZILITE Simple painless non-invasive technology to visualize suspicious areas at earlier stages what we may not see by naked eyes .It’s based onthe principle of CHEMILUMINESCENCE

  8. ACTION OF VIZILITE • Under vizilite normal healthy tissue will absorb light & appear dark. Abnormal tissue will appear white.

  9. HOW VIZILITE WORKS?

  10. STEPS

  11. Make the room dark & re-examine the oral cavity with vizilite

  12. Intra-oral vital staining With Toluidine blue helps to identify dysplastic and malignant mucous membrane in the oral cavity.

  13. STEPS

  14. VIZILITE &TOLUIDINE BLUE

  15. IR THERMOGRAPHY • It uses the heat of our body to aid in making diagnosis.It is completely safe and uses no radiation. 2 parts-1.IR CAMERA 2.HIGH RESOLUTION COMPUTER

  16. MECHANISM Detection of breast cancer Use in oral cancer –on way

  17. ADJUNCT TO SURGICAL BIOPSY

  18. CONCLUSION • These screening techniques help in early detection of malignancy with an accuracy of 90 % and thus %
