Title: Early methods of diagnostic in oral medicine

Early methods of diagnostic in oral medicine

  • The five-year mortality rate of Oral Cancer is
    higher than, cervical cancer and prostate cancer,
    and kills one person every hour of every day.
  • Why are we not speaking about it?Why are we not
    screening for it at every visit?Why are we not
    detecting it earlier - when the cure rates are
    80-90 percent?
  • Because the signs and symptoms of oral cancer are
    often missed by the naked eye!

  • Dentists and hygienists are the best overall
    defense against oral cancer they are, in fact,
    a lifesaver.
  • No other medical professionals are as well
    positioned to address this potentially deadly
    disease at its earliest stage.
  • The key is to identify oral abnormalities at
    their most easily treated stage of development.

 Early Detection is Critical !!!

Biopsy
  • Biopsy is a microscopic examination of a tissue
    sample to see if the cells are indeed cancer
    cells or not. Biopsy only occurs after you have
    identified the lesion. Biopsy is the next step
    in this entire process.
  • What we have been missing in dentistry is this
    screening process which can easily identify
    pre-malignant and malignant lesions before you
    can either possibly see them or if in fact you do
    see them but are not sure if they should be
    biopsied.

6
We are blessed today to have oral cancer
screening tools available.So, lets speak about
some of them.

VELscope
  • Most effective as a component of comprehensive
    patient care, the VELscope Vx is introduced as
    part of the intra-oral and extra-oral exam.
  • After discussing the exam with the patient,
    VELscope Vx's blue excitation light is shone into
    the oral cavity.
  • Abnormal tissue typically appears as an
    irregular, dark area that stands out against the
    green fluorescence pattern of surrounding healthy
    tissue.

  •  The VELscope hand piece emits a safe blue light
    into the oral cavity, causing tissue fluorescence
    from the surface of the epithelium through to the
    basal membrane   where pre-malignant changes
    typically start.
  • By utilizing special optical filters in the
    VELscope hand piece the clinician is able to
    immediately view the different fluorescence
    signatures in the oral tissue to help
    differentiate between normal and abnormal
    cellular activity.

Orascoptic DK
  • The DK oral lesion screening instrument works in
    conjunction with a mild acetic acid rinse to
    improve the visualization of oral lesions.
  • The DK exam enhances the ability to identify
    potentially cancerous tissue at its earliest
    stages.
  • Early detection of pre-cancerous tissue can
    minimize or eliminate the disfiguring effects of
    oral cancer and possibly save a life!

16
Orascoptic DK 
  • The oral lesion screening instrument works in
    conjunction with an acetic acid rinse to improve
    the visualization of lesions.
  • The device also includes a transillumination
    instrument and lighted mirror.

17
Orascoptic DK 
  • Product Bief - Orascoptic DK uses a battery
    powered handheld LED light source and 3
    interchangeable diagnostic instruments.
  • Special Features - Transillumination instrument,
    mirror
  • How it Works - Mild Acetic acid rinse for the
    visualization of oral lesions

18
Microlux Diagnostic Light (Microlux/DL)
  • With refractive light technology already proven
    to help save lives in the detection of
    pre-cancerous cervical abnormalities,
    the Microlux Diagnostic Light (Microlux/DL) makes
    this advance in patient care simple and
    inexpensive.
  • When used in conjunction with conventional oral
    mucosal exams, it improves identification,
    evaluation, and monitoring of soft tissue
    abnormalities and changes in all patients.

19
Microlux Diagnostic Light (Microlux/DL)
  •  After noting any acetowhite soft tissue lesions
    during a routine exam, simply have the patient
    rinse with the Microlux DL 1 acetic acid
    solution for 60 seconds.
  • Then, repeat the oral exam using the Microlux DL.
  • Since the acetic acid dehydrates the cytoplasm of
    acetowhite lesions, the lesions refractive
    properties are changed.
  • Under diffused light from the special Microlux/DL
    fiberoptic light guide, acetowhite or leukoplakic
    lesions become more visible.
  • The irregular cells take on a whitish hue which
    contrasts with surrounding tissue, helping to
    identify abnormalities which require further
    testing.

20
Identafi3000 ultra
  • The Identafi uses white, violet and amber
    wavelengths of light to excite oral tissue in
    distinct and unique ways.
  • As a result, biochemical changes can be monitored
    with fluorescence, while morphological changes
    can be monitored with reflectance.
  • The combined system of fluorescence and
    reflectance uses the body's natural tissue
    properties as an adjunctive tool for oral mucosal
    examination.

21
Identafi
  •  The device minimizes false positives while
    disclosing abnormalities in oral tissue that
    otherwise would be missed by the naked eye.

23
ViziLite Plus with TBlue630
  • ViziLite Plus with TBlue630 is an oral lesion
    identification and marking system that is used as
    an adjunct to the conventional head and neck
    examination.
  • It is comprised of a chemiluminescent light
    source (ViziLite) to improve the identification
    of lesions and a blue phenothiazine dye to mark
    those lesions identified by ViziLite. 

24
How ViziLite Plus Works
  • Similarly in the oral cavity, after rinsing with
    a dilute acetic acid solution, abnormal squamous
    epithelium tissue will appear acetowhite when
    viewed under ViziLite's diffuse low-energy
    wavelength light.
  • Normal epithelium will absorb the light and
    appear dark. ViziLite can assist a dentist or
    hygienist in identifying an abnormality in the
    oral cavity.

  • So, lets be the real physicians of the mouth that
    our patients expect us to be!
