Outcome Measures

Primary Outcomes (1)

  • To establish a preliminary estimate of the sensitivity and specificity of the Active Biopsy Guidance System with respect to histopathology

    Through study completion an average of 1 year.

Study Arms (1)

The Active Biopsy Guidance System

EXPERIMENTAL

This imaging scanning device is made up of 2 parts: the optical mapping scope and the high-resolution microendoscope (HRME):

Device: High Resolution Microendoscope (HRME)Device: Optical Mapping ScopeDrug: Proflavine hemisulfate

Interventions

The High Resolution Microendoscope (HRME) take pictures of a very small area of the lining of the mouth, about the size of a pencil tip, but at high magnification.

The Active Biopsy Guidance System

The optical mapping scope displays a wide area of the lining of the mouth (about the size of the top of a soda can) by shining different colors of light into the mouth and taking pictures.

The Active Biopsy Guidance System

A coloring substance (a fluorescent dye which glows green in the dark), called proflavine hemisulfate, will be painted on areas of the mouth with a cotton tip applicator to help improve the pictures
