This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers are testing a device called GOCCLES®—special glasses that use ultraviolet light to detect early warning signs of oral cancer. The study will compare how well this device works compared to a traditional staining method (blue toluidine) that doctors currently use. The goal is to see if GOCCLES® can help catch dangerous mouth changes earlier, when they're easier to treat.
Oral cancer is often caught too late, when it's harder to treat. Doctors need better tools to spot dangerous changes in the mouth early, before they become full-blown cancer. This trial will test whether this new screening device works better than methods doctors use today.

You will visit the clinic once for an examination. First, a doctor will look at and measure your mouth sore. Then they will use the GOCCLES® device (special glasses with ultraviolet light) to examine the area and take photos. Next, they will apply a blue stain to the area to see if it highlights anything concerning, and take more photos. Finally, the doctor will take a small tissue sample (biopsy) from the area for lab testing to find out exactly what's going on.
