VELscope® Technology

The VELscope® Vx Enhanced Oral Assessment System centers on a handheld scope that is used by dentists to help detect oral tissue abnormalities, including cancer and pre-cancer.

The VELscope® Vx system is an adjunctive device which means it must be used together with and as a supplement to the traditional intra and extra oral head and neck exam. Unlike other adjunctive devices used for oral examinations, the VELscope® Vx does not require any dyes or prolonged testing procedures. In fact, a VELscope® Vx exam can be performed in the dentist's office during a routine hygiene exam in about two minutes.

A New Way to Examine for Oral Disease

VELscope® Vx technology is changing the way oral mucosal examinations take place. The VELscope® Vx handheld device emits a harmless, bright blue light which is used to inspect the mouth and tongue. The device is extremely sensitive to abnormal tissue changes and the distinctive blue-spectrum light causes the soft tissue (oral mucosa) of the mouth to naturally fluoresce. Healthy tissues fluoresce in distinct patterns that are visibly disrupted by trauma or disease, such as neoplastic lesions, and fungal, viral or bacterial infections.

Supplementing the COE

Dentists use the VELscope® Vx device to supplement the traditional intra and extra oral head and neck exam (also referred to as the comprehensive oral exam or "COE"), and they are rapidly embracing the use of this device to help detect abnormal oral tissue such as potential cancerous or pre-cancerous tissues that are not apparent or sometimes not even visible with the naked eye alone. Exams can be more thorough and any suspicious areas can be quickly investigated for confirmation of oral disease.

Why Early Discovery Matters?

The VELscope device is an imaging modality which is extremely sensitive to tissue changes. Its use in everyday practice can provide timely information to dentists and hygienists to enable earlier detection of abnormal tissues and provide better outcomes for patients.

The statistics are highly favourable: when discovered early the 5-year survival rate for oral cancer patients is about 83%. Unfortunately, most cases of oral cancer are discovered in late stages, when the five-year survival rate drops to around 50 percent.

Changing Demographics

New research confirms that the risk factors for oral cancer have been expanded to include the Human Papilloma Virus (HPV16), in addition to tobacco use, frequent and/or excessive alcohol consumption, a compromised immune system, and past history of cancer. This changing demographic presents an unprecedented call to action for oral cancer awareness and regular screenings.
