Oral Cancer Detection Devices
Recently, we had a Twitter follower ask us what the latest methods of detecting oral cancer are. With Twitter’s allowances of only 140 characters to answer the question, we decided to post a blog that gives a more in depth look at the state of oral cancer detection devices.
The main oral cancer detection devices that are on the market today are:
- Brush biopsy – “The OralCDx® BrushTest®is an easy, painless and definitive way for dentists to test the common small white and red oral spots that most people have in their mouth at one time or another. The BrushTest is used to determine if a common oral spot contains abnormal cells (known as dysplasia) that, if left alone for several years, may develop into oral cancer.”
- ViziLite Plus, MicroLux DL – A light technology that “in combination with a regular visual examination, provides a comprehensive oral screening procedure for patients at increased risk for oral cancer.”
- Velscope - “The ‘white light’ exam. The VELscope exam is actually the second step in a comprehensive oral cancer exam. The first step is a conventional ‘white light’ exam in which the dentist or hygienist looks for lesions in the oral cavity with the naked eye and uses palpation to feel for any bumps in the neck or face.”
- Trimira OCS 3000 – Trimira’s®, new Identafi® 3000 ultra uses the Identafi® Multi-Spectral Fluorescence and Reflectance technology to enhance visualization of mucosal abnormalities such as oral cancer or premalignant dysplasia that may not be apparent to the naked eye. But unlike other fluorescence technologies and dye systems, the Identafi® 3000 ultra is Multi-Spectral with three distinct color wavelengths, making it easier to distinguish lesion morphology and vasculature thereby reducing false positives.
The oral cancer detection devices mentioned above are only tools for screening and are not designed to diagnose oral cancer. They result false negatives if not used appropriately. The ideal screening is a conventional visual oral tactile exam at the dental office first.
Visiting a pathologist in suspicious cases is highly recommended. A second opinion can save you a lifetime. Do not wait and watch the cancer grow in your mouth.

Oral Cancer Screening: Reviewing the New Technologies
There are many technologies that boast of the ability to detect pre-cancer conditions for oral cancer. These oral cancer screening technologies look for abnormal cells that when detected will allow the physician to be able to more precisely locate risk areas and do a more thorough assessment. However, the question arises: “Do these technologies truly live up to their claims?”
The research in the article Oral Precancer and Early Cancer Detection- A Review of Technologies by Jerry E. Bouquot, DDS, MSD, Patricia Suarez, DDS, MS and Nadarajah Vigneswaran, BDS, DMD3 provides an overview and summary of the technologies that are out there, determining if they are what they claim to be.
In reviewing oral cancer screening, the procedures that are covered are:
- The Brush Biopsy
- Toluidine Blue – in Vivo Staining of DnA in the Dental Office
- The ViziLite – Highlighting the Keratin
- Oral Autofluorescence – When the Mucosa doesn’t glow
In conclusion on their oral cancer screening technology review they had this to say:
“Our intention is not to recommend one of these technologies over another, but the future looks most bright for the optical autofluorescence technology (pardon our pun), combined with either a biopsy, brush biopsy or LBC. All devices have limitations and the published research is sparse, but until other methods are developed, such as the use of molecular markers in salivary proteomics or genomics, it is heartening to know that relatively acceptable in-office devices are already available and can be used as adjunctive diagnostic tools. Refinements and continued research will undoubtedly improve our ability to detect, at the earliest possible stage, dysplastic changes in our patients, and new technologies may emerge quickly which will prove much more valuable. Until then, it is refreshing to be practicing dentistry during a time of such exciting emerging technologies attempting to address one of the most frustrating and serious of our oral diagnostic dilemmas.”
