Every hour in our country, one patient died of oral cancer! Oral cancer increases at an annual rate of 11%. Oral cancer mortality is now higher than cancer, such as cervical cancer, thyroid cancer, Hodgkin's lymphoma, testicular cancer, laryngeal cancer or malignant melanoma. Due to the late diagnosis, more than 5,000 men and 2,000 women died of oral cancer each year. Compared with dentists, more doctors diagnose oral cancer. Of course, we should be the first line of defense against oral cancer.
More than 40% of patients diagnosed with oral cancer have a history of non-delivery - they do not smoke or smokeless tobacco, and they do not drink too much alcohol. Due to sexual transmission of HPV 16 and 18 (human papillomavirus), oral cancer in young people has increased by 500%.
Unfortunately, 62% of oral cancer cases were diagnosed with a poor prognosis in stage III or IV. By early detection, there can be a survival rate of 80 to 90%; however, this disease is not always obvious at an early stage. The survival rate in the past 40 years has hardly improved.
Because Identafi® oral cancer screening systems use technologies such as “multi-spectral” imaging (triwavelength spectroscopy), better patient care and early detection can be achieved! The purple wavelength of the dental instruments is the optimal excitation wavelength to distinguish tumor and non-tumor tissue regions.
By early detection, there can be a survival rate of 80 to 90%; however, this disease is not always obvious at an early stage.
Identafi uses white, green-amber and violet wavelengths of light to distinguish between normal and abnormal tissue.
First, the 12 areas of the oral cavity were observed with concentrated white light to provide a regular appearance on the tissue. Next, observe the same area with a purple wavelength that enhances the natural fluorescence of the tissue. The clinician wears filter glasses that block the violet excitation light and allow observation of the tissue's natural fluorescence.
Suspicious organizations appear dark due to the lack of flowering. Third, when a suspicious tissue area is detected with a purple wavelength, a green-amber wavelength is used because it enhances the reflection characteristics of normal tissue. The clinician can observe the difference between normal and abnormal tissue vasculature. Normal tissue has a more definite vascular appearance, whereas abnormal tissue has more diffuse vascular appearance.
This can minimize false alarms and reduce the number of biopsy. In fact, only 10% of the famous areas do have some worrying things. In this case, the vasculature does not appear to be diffuse; however, due to the history of smoking, biopsy was performed anyway. Biopsy results showed that the lesion was benign.
During the first six months of implementing Ideafi, we diagnosed two cases of squamous cell carcinoma, two cases of precancerous lesions, and one case of benign but very severe jugular venous glomeruli. If this enhanced oral cancer screening dental equipment can only save one life, then this would be a worthwhile investment.
