velscope What.jpg

  • A cordless device that uses fluorescent lights of green, yellow and green
  • Reflects blue light to help show contrast between what is normal and abnormal tissue
  • It is used for detecting oral cancer both pre-cancer and cancerous, as well as other abnormalities that can be found in the mouth, lips and throat.
  • It is a short procedure that takes approximately one to two minutes.
  • It is painless and tasteless
  • FDA approved for use in clinical practice

velscope how to.jpg

  1. Perform regular extra-oral and intra-oral assessment on client.
  2. Use VELscope Vx to assess intra-oral tissues. Space between the oral cavity should be about 2 inches (5 cm.)
  3. If irregular tissues found, assess the area again to confirm the oral lesion with regular lighting and use of Velscope Vx.
  4. Write any abnormalities in the client’s chart. Take a picture if possible.
  5. Make a client referral if further investigation needed or assess again on a later date.

    Normal tissues - appear as uniform shades of green
    Irregular tissues – “appears as an irregular, dark area that stands out"

velscope Study.jpg

Article # 1 - Summary
Rahman, M., Ingole, N., Roblyer, D., Stepanek, V., Richards-Kortum, R., Gillenwater, A., Shastri, S., and Chaturvedi, P. (2010). Evaluation of a low-cost, portable imaging system for early detection of oral cancer. Head & Neck Oncology 2010, 2, 1-8.

INTRODUCTION
A malignant tissue is a type of tissue that does not respond to treatment. It is most likely fatal, and could cause death. When it is identified as a malignant, it is cancerous. Oral cancer is one of the most common types of cancer. Such condition can be prevented if detected in the early stages.

109 individuals participated in the clinical study for soft tissue areas with a possibility of finding malignant tissues in their oral cavity. It took place at a hospital in India. Candidates were selected through referrals, due to a sign or symptom of abnormal oral tissues, and volunteers who had past tobacco experience or not. Informed consent was acquired from participants in the research study.

METHODS
Initially, each client received a thorough examination from a “head and neck specialist”. Healthy and irregular tissues were documented. Then, irregular tissues were carefully examined through the use of fluorescent devices. “Lateral border of the tongue, buccal mucosa, and the lip” were also assessed. Finally, non-diagnostic images were not used.
Clinical findings were assessed by knowledgeable individuals by categorizing it to classifications as “normal, low risk for neoplasia, high risk for neoplasia, or cancer.” Each region was appraised using a white light and fluorescent device with the use of different fluorescent colors: “red, green, and blue”, or varying combination of two colors. It was then analyzed, and categorized to differentiate what is normal and not.

RESULTS

Table 1. (Rahman, et al., 2010)
Result of 351 images collected from various areas of the oral cavity


velscope Fig 1.jpg
Figure 4. (Rahman, et al., 2010)
Tissues observed under fluorescent light are as follows:
  • Normal tissues - uniform shades of green
  • Low and high risk for neoplasia - decrease shades of green
  • Cancer - absence color of green, with varying colours of orange and red seen

Five graphs were used to interpret collected data (images) according to type of tissue category and specificity (individuals not affected in the study). Findings from this study produced the same results when compared with other existing analysis. Restrictions of the study include: same data were used for categorizing and evaluating the analysis, therefore reliability of the data may not be accurate; required areas to detect may not be all included due to the extent of available resources; and areas may be categorized in the wrong type (such as low risk areas in this study).

CONCLUSION
An actual study was used in this research to assess how an electronic device can distinguish tissue types, normal and irregular, in the oral cavity. Outcome of this clinical study may be limited due to the available sources, but it can still be used by a health care professional who has knowledge deficit of performing thorough intra-oral assessment and/or when other resources may not be present.

"I have found VELscope to be a very useful addition to the diagnostic methods used for the detection and management of oral dysplastic and malignant lesions. In the year that I have used the VELscope there have been several occasions where its use allowed detection of malignant or dysplastic oral lesions when clinical suspicion of the lesion was very low or nonexistent. The scope is easy to use and provides a more objective method than visual inspection alone for determination of which lesions demand immediate biopsy and more aggressive follow-up. Adding the VELscope to our diagnostic protocol has been extremely useful and resulted in detection of dangerous lesions that would have otherwise been undetected."
Anthony Palombaro, DDS

“A scan told us the patient had cancer, but we couldn’t find the primary source by just looking in her mouth with regular light. Using a VELscope exam, I was able to visualize the oral source of the cancer. The surgeon removed it, and the patient is still with us over 6 years later. VELscope literally saved the patient's life."
Tony Hewlett, DDS
Standwood, WA
“I find the VELscope to be an invaluable tool for the detection of oral cancer. The response from my patients has been overwhelmingly positive. I have yet to have a patient decline the service. In my opinion, this technology will be the standard of care in a short period of time. There is no other adjunctive method available to so accurately help find areas of oral cancer at a stage that is so readily treatable. I am so pleased with the device I am about to purchase another VELscope to make sharing the unit within my office easier.”
Ken Neuman, DMD, FAGD, FADI, FICD, FACD
“Dentists saving lives? Now more than ever a reality with the development of VELscope. As easy as looking through a camera lens, we are now better equipped to discover potentially malignant lesions in time to save many lives. Every dental office needs this instrument.”
Dr. George Moss D.D.S. F.A.G.D.
Lakewood Park Dental
Lake Conroe, Texas
“My office has been using VELscope for almost a year, and my associate and I have definitely become more thorough in our oral cancer exam. We have discovered and confirmed dysplasias and several benign lesions that would probably have been missed had it not been for our use of the Velscope. We feel strongly that all dental offices should provide this service."
