VELscope Vx Step-By-Step
Examination Guide
Note: This is an abbreviated clinical guide. Please see the
VELscope Vx Training DVD for more detailed information.
1
Review the patient's relevant medical and
dental history.
2
Conduct a thorough extra-oral and intra-oral
examination both visually and manually, palpating
all the structures of the head and neck.
3
Repeat the intra-oral examination using the
VELscope Vx by viewing the oral cavity through
the VELscope Handpiece (Figure 1). Maintain a
distance of approximately 2 inches (5 cm) from
the oral cavity to optimize the visualization of the
natural tissue fluorescence.
4
Abnormal tissue typically appears as an irregular,
dark area that stands out against the otherwise
normal, green fluorescence pattern of surrounding
healthy tissue.
5
If a suspicious area is discovered, reevaluate under
white light and VELscope trying to identify what
might have caused the region to appear abnormal.
Take into consideration its appearance under
both VELscope and white light, its response to
palpation, and salient patient history information.
6
Photo-document any areas of concern both under
white light and through the VELscope Vx.
7
Record all relevant findings. Documentation forms
are available at www.velscope.com.
8
Inform the patient of all relevant findings and the
appropriate course of action.
9
Follow up or refer as appropriate.

VELscope Vx examination: The clinician shines the • blue excitation light into the patient’s oral cavity and looks precancerous and cancerous lesions in the soft through the VELscope Handpiece tissues of the oral cavity is surgical biopsy.
- Page 3 Figure 2. Representative examples of the appearance of healthy vs. suspicious oral tissue under both incandescent light and VELscope examination. Normal Floor of the Mouth Sometimes the area around the sub-lingual gland can be well vascularized, and can lead to a variable degree of loss of fluorescence.
- Page 4 Pigmented Lesions: Amalgam Tattoo Pigmented lesions show a loss of fluorescence for the same reason that they appear pigmented under white light: absorption of light by the pigment. One should expect the size and shape of the loss of fluorescence to be the same as the size and shape of the pigmented area under white light. Erosive Lichen Planus The intense inflammation associated with erosive lichen planus results in a pronounced loss of fluorescence.
