Can we differentiate with pictures and explanation between fissured and pathological tongue disease? i am worry and not sure what i have.

Yes and no: Fissured tongue really isnt a disease. It's just a characteristic that some people have. For an example, i've included a photo of fissured tongue. There are differing degrees as well, some more or less pronounced. If there is a concern that you have some sort of pathology, see a dentist for a professional opinion.

No: Pictures alone will not help tell the difference. Many new instruments are on the market one such is called veld cope this shines a light into the mouth which penetrates the tissue any irregular, did plastic, cancerous cells will come back a different color as you look through a special lens. This unit has a camera which can be attach to it so you can take a picture.
